Using Docker for Full Stack Development and Deployment

1. Introduction to Docker

What is Docker? Docker is an open-source platform that automates the deployment, scaling, and management of applications inside containers. A container packages your application and its dependencies, ensuring it runs consistently across different computing environments.

Containers vs Virtual Machines (VMs)

Containers are lightweight and use fewer resources than VMs because they share the host operating system’s kernel, while VMs simulate an entire operating system. Containers are more efficient and easier to deploy.

Docker containers provide faster startup times, less overhead, and portability across development, staging, and production environments.

Benefits of Docker in Full Stack Development

Portability: Docker ensures that your application runs the same way regardless of the environment (dev, test, or production).

Consistency: Developers can share Dockerfiles to create identical environments for different developers.

Scalability: Docker containers can be quickly replicated, allowing your application to scale horizontally without a lot of overhead.

Isolation: Docker containers provide isolated environments for each part of your application, ensuring that dependencies don’t conflict.

2. Setting Up Docker for Full Stack Applications

Installing Docker and Docker Compose

Docker can be installed on any system (Windows, macOS, Linux). Provide steps for installing Docker and Docker Compose (which simplifies multi-container management).

Commands:

docker --version to check the installed Docker version.

docker-compose --version to check the Docker Compose version.

Setting Up Project Structure

Organize your project into different directories (e.g., /frontend, /backend, /db).

Each service will have its own Dockerfile and configuration file for Docker Compose.

3. Creating Dockerfiles for Frontend and Backend

Dockerfile for the Frontend:

For a React/Angular app:

Dockerfile

FROM node:14 WORKDIR /app COPY package*.json ./ RUN npm install COPY . . EXPOSE 3000 CMD ["npm", "start"]

This Dockerfile installs Node.js dependencies, copies the application, exposes the appropriate port, and starts the server.

Dockerfile for the Backend:

For a Python Flask app

Dockerfile

FROM python:3.9 WORKDIR /app COPY requirements.txt . RUN pip install -r requirements.txt COPY . . EXPOSE 5000 CMD ["python", "app.py"]

For a Java Spring Boot app:

Dockerfile

FROM openjdk:11 WORKDIR /app COPY target/my-app.jar my-app.jar EXPOSE 8080 CMD ["java", "-jar", "my-app.jar"]

This Dockerfile installs the necessary dependencies, copies the code, exposes the necessary port, and runs the app.

4. Docker Compose for Multi-Container Applications

What is Docker Compose? Docker Compose is a tool for defining and running multi-container Docker applications. With a docker-compose.yml file, you can configure services, networks, and volumes.

docker-compose.yml Example:

yaml

version: "3" services: frontend: build: context: ./frontend ports: - "3000:3000" backend: build: context: ./backend ports: - "5000:5000" depends_on: - db db: image: postgres environment: POSTGRES_USER: user POSTGRES_PASSWORD: password POSTGRES_DB: mydb

This YAML file defines three services: frontend, backend, and a PostgreSQL database. It also sets up networking and environment variables.

5. Building and Running Docker Containers

Building Docker Images:

Use docker build -t <image_name> <path> to build images.

For example:

bash

docker build -t frontend ./frontend docker build -t backend ./backend

Running Containers:

You can run individual containers using docker run or use Docker Compose to start all services:

bash

docker-compose up

Use docker ps to list running containers, and docker logs <container_id> to check logs.

Stopping and Removing Containers:

Use docker stop <container_id> and docker rm <container_id> to stop and remove containers.

With Docker Compose: docker-compose down to stop and remove all services.

6. Dockerizing Databases

Running Databases in Docker:

You can easily run databases like PostgreSQL, MySQL, or MongoDB as Docker containers.

Example for PostgreSQL in docker-compose.yml:

yaml

db: image: postgres environment: POSTGRES_USER: user POSTGRES_PASSWORD: password POSTGRES_DB: mydb

Persistent Storage with Docker Volumes:

Use Docker volumes to persist database data even when containers are stopped or removed:

yaml

volumes: - db_data:/var/lib/postgresql/data

Define the volume at the bottom of the file:

yaml

volumes: db_data:

Connecting Backend to Databases:

Your backend services can access databases via Docker networking. In the backend service, refer to the database by its service name (e.g., db).

7. Continuous Integration and Deployment (CI/CD) with Docker

Setting Up a CI/CD Pipeline:

Use Docker in CI/CD pipelines to ensure consistency across environments.

Example: GitHub Actions or Jenkins pipeline using Docker to build and push images.

Example .github/workflows/docker.yml:

yaml

name: CI/CD Pipeline on: [push] jobs: build: runs-on: ubuntu-latest steps: - name: Checkout Code uses: actions/checkout@v2 - name: Build Docker Image run: docker build -t myapp . - name: Push Docker Image run: docker push myapp

Automating Deployment:

Once images are built and pushed to a Docker registry (e.g., Docker Hub, Amazon ECR), they can be pulled into your production or staging environment.

8. Scaling Applications with Docker

Docker Swarm for Orchestration:

Docker Swarm is a native clustering and orchestration tool for Docker. You can scale your services by specifying the number of replicas.

Example:

bash

docker service scale myapp=5

Kubernetes for Advanced Orchestration:

Kubernetes (K8s) is more complex but offers greater scalability and fault tolerance. It can manage Docker containers at scale.

Load Balancing and Service Discovery:

Use Docker Swarm or Kubernetes to automatically load balance traffic to different container replicas.

9. Best Practices

Optimizing Docker Images:

Use smaller base images (e.g., alpine images) to reduce image size.

Use multi-stage builds to avoid unnecessary dependencies in the final image.

Environment Variables and Secrets Management:

Store sensitive data like API keys or database credentials in Docker secrets or environment variables rather than hardcoding them.

Logging and Monitoring:

Use tools like Docker’s built-in logging drivers, or integrate with ELK stack (Elasticsearch, Logstash, Kibana) for advanced logging.

For monitoring, tools like Prometheus and Grafana can be used to track Docker container metrics.

10. Conclusion

Why Use Docker in Full Stack Development? Docker simplifies the management of complex full-stack applications by ensuring consistent environments across all stages of development. It also offers significant performance benefits and scalability options.

Recommendations:

Encourage users to integrate Docker with CI/CD pipelines for automated builds and deployment.

Mention the use of Docker for microservices architecture, enabling easy scaling and management of individual services.

The data directory contains an old postmaster.pid file

PostgreSQL Connection Failure

I experienced this issue when my laptop crushed and after rebooting, PostgreSQL was unable to connect to the database. I attempted to start my server and this error dialog window appeared.

The Problem: Two instances of the same PostgreSQL server cannot run on the same data directory at the same time thanks to the postmaster.pid lock file. Follow the link for more information about what a postmaster.pid file is, otherwise let's move on to resolving our issues.

STEP 1:

Click on the “OK” button to close the dialog window or open the Postgres.app desktop app if its not already open

STEP 2

Click on “Server Settings…” button

Click on Show button next to the Data Directory. This should open the data directory of your PostgreSQl installation.

STEP 3

Once you have located your postmaster.pid file. Delete it!

STEP 4

After deleting the file, the error message should change from "Stale postmaster.pid file" to "Not running" on the Postgres GUI app . Now just start your PostgreSQL server by clicking the "Start" button on the Postgres GUI app

#Installing postgres app how to#

See Removing Existing PostgreSQL Installations on the Postgres.app website for instructions on how to do this. It’s recommended that you remove any pre-existing PostgreSQL installations before installing Postgres.app. If you do, you’ll run into problems, if both versions are trying to use the same port (5432 is the default port). The above instructions assume you don’t already have PostgreSQL running on your Mac. sudo mkdir -p /etc/paths.d &Įcho /Applications/Postgres.app/Contents/Versions/latest/bin | sudo tee /etc/paths.d/postgresapp Remove Existing Installations You can also configure your $PATH to use the included command line tools. This will connect to your default database.Īnother alternative is to use a GUI application, such as pgAdmin, DBeaver, Postico, Azure Data Studio, etc. This will connect to that database using the psql command line interface.Īlternatively, you can launch psql in a separate terminal window and type psql. To connect to a database, double click one of the database icons shown in the above screen. You can start and stop PostgreSQL using the relevant buttons on this panel.

#Installing postgres app install#

When you install Postgres.app, several databases are created by default, including one using your system username. Once you’ve done that, you should see a screen similar to the following:

Double-click the Postgres.app icon (in your Applications folder).

Drag the Postgres.app icon to your Applications folder.ĭone.

#Installing postgres app download#

Download the latest version of Postgres.app from the Postgres.app website.

Here are step-by-step instructions for installing PostgreSQL.app on your Mac. You simply download it and drag it to your Applications folder, just like with any other application.

#Installing postgres app mac#

Postgres.app is a full-featured PostgreSQL installation packaged as a standard Mac application. While you can configure PATH for this to work, there is easier solution.The easiest way to install PostgreSQL on a Mac is by installing Postgres.app. Because this package for the setup expects to find standard Postgres installation on your machine. However this won't work on your local machine. If you already deployed your app on the server with Postgres, you probably installed the psycopg2 package to talk to the database. Click the "Start" button and your server is ready to go. Now all that is left to do is to run the app. Download it, open and move the Postgres.app to Applications folder on your Mac. The most up to date version is "Postgres.app with PostgreSQL 13" as of writing this post in December 2020. You can get the dmg file from the official site. This also assumes you don't have other versions of Postgres installed. There are more than one ways how to install this database on your machine, however downloading Postgres.app is the easiest. We will start with the Postgres part that is not Django specific. So developing this feature without Postgres database would be kind of crazy.Īnyway, let's see how to setup Postgres locally. Add -set flags to the command to connect the installation to the PVC you created and enable volume permissions: helm install release-name repo-name -set persistence.existingClaim pvc-name -set volumePermissions.enabledtrue. Postgres offers powerful full-text search you can use from Django. Install the helm chart with the helm install command. In my case, what kind of forced me to have local PostgreSQL for one of my projects, was search. For example SQLite does not care about length of the text in columns. You can get yourself into a situation where your app works locally but does not start on the server, because there is a small difference in how these two databases work. While this setup is pretty easy (you get configuration for SQLite out of the box) it has some issues. With Django I would say it is pretty common to have SQLite as a developer database and then on the server have Postgres as "the real" production database.

Now, we can give our new user access to administer our new database:

ALTER ROLE myprojectuser SET timezone TO 'UTC'.

ALTER ROLE myprojectuser SET default_transaction_isolation TO 'read committed'.

ALTER ROLE myprojectuser SET client_encoding TO 'utf8'.

These are all recommendations from the Django project itself: By default, our Django projects will be set to use UTC. We are also setting the default transaction isolation scheme to “read committed”, which blocks reads from uncommitted transactions. We are setting the default encoding to UTF-8, which Django expects. This will speed up database operations so that the correct values do not have to be queried and set each time a connection is established.

#INSTALLING POSTGRES APP PASSWORD#

CREATE USER myprojectuser WITH PASSWORD ' password' Īfterwards, we’ll modify a few of the connection parameters for the user we just created.

Next, create a database user for our project. Note: Every Postgres statement must end with a semi-colon, so make sure that your command ends with one if you are experiencing issues. You will be given a PostgreSQL prompt where we can set up our requirements.įirst, create a database for your project: Log into an interactive Postgres session by typing: We can use sudo and pass in the username with the -u option. We need to use this user to perform administrative tasks. Basically, this means that if the user’s operating system username matches a valid Postgres username, that user can login with no further authentication.ĭuring the Postgres installation, an operating system user named postgres was created to correspond to the postgres PostgreSQL administrative user. We’re going to jump right in and create a database and database user for our Django application.īy default, Postgres uses an authentication scheme called “peer authentication” for local connections. Creating the PostgreSQL Database and User

#INSTALLING POSTGRES APP INSTALL#

This will install pip, the Python development files needed to build Gunicorn later, the Postgres database system and the libraries needed to interact with it, and the Nginx web server.

sudo apt install python-pip python-dev libpq-dev postgresql postgresql-contrib nginx curl.

If you are starting new projects, it is strongly recommended that you choose Python 3.

sudo apt install python3-pip python3-dev libpq-dev postgresql postgresql-contrib nginx curlĭjango 1.11 is the last release of Django that will support Python 2.

If you are using Django with Python 3, type: The packages we install depend on which version of Python your project will use.

#INSTALLING POSTGRES APP UPDATE#

We need to update the local apt package index and then download and install the packages. We will use the Python package manager pip to install additional components a bit later. To begin the process, we’ll download and install all of the items we need from the Ubuntu repositories. Installing the Packages from the Ubuntu Repositories We will then set up Nginx in front of Gunicorn to take advantage of its high performance connection handling mechanisms and its easy-to-implement security features. This will serve as an interface to our application, translating client requests from HTTP to Python calls that our application can process. Once we have our database and application up and running, we will install and configure the Gunicorn application server. Installing Django into an environment specific to your project will allow your projects and their requirements to be handled separately. We will be installing Django within a virtual environment.

#INSTALLING POSTGRES APP HOW TO#

You can learn how to set this up by running through our initial server setup guide. In order to complete this guide, you should have a fresh Ubuntu 20.04 server instance with a basic firewall and a non-root user with sudo privileges configured. We will then set up Nginx to reverse proxy to Gunicorn, giving us access to its security and performance features to serve our apps. We will configure the Gunicorn application server to interface with our applications. We will be setting up a PostgreSQL database instead of using the default SQLite database. In this guide, we will demonstrate how to install and configure some components on Ubuntu 20.04 to support and serve Django applications.

#INSTALLING POSTGRES APP CODE#

Django includes a simplified development server for testing your code locally, but for anything even slightly production related, a more secure and powerful web server is required.

Apple M1 para desenvolvedores do zero - Part 1

Eae, essa vai ser uma série ( espero ) de artigos de tudo que fiz assim que recebi o meu Macbook Air com processador M1. Espero que te ajude migrar todo seu ambiente Intel para M1 ( arm64 ).

Infelizmente ainda temos um caminho longo pela frente, boa parte dos softwares já conseguem ser compilados nativamente, porem, outros ainda precisam ser emulados atrav'ées do Rosetta por conta de bibliotecas de sistema com "ffi" que ainda não estao 100% compativels.

Separei em topicos de passos que segui exatamente na ordem que estão, espero que ajude.

Xcode + Rosetta

A instalação é feita através da App Store. Antes de começar toda a configuração da maquina instale a versão mais recente.

Em seguida instalar componentes de desenvolvimento: xcode-select --install

Brew no M1 ( Gerenciador de Pacotes )

As instalação do brew eu segui as instruções dadas a partir do artigo:

https://gist.github.com/nrubin29/bea5aa83e8dfa91370fe83b62dad6dfa

Instalando dependências de sistema

Essas bibliotecas servirão para diversos softwares como Python, Pillow, Node e etc. Elas são necessárias para a compilação e uso dos mesmos.

brew install libtiff libjpeg webp little-cms2 freetype harfbuzz fribidi brew install openblas brew install blis brew install zlib brew install gdal brew install pyenv brew install geoip brew install libgeoip brew install libffi brew install xz

Opcionais:

brew install postgres

Instalando Pyenv no M1

Instalando pyenv para facilitar o isolavento e definição de versões do python no sistema.

Eu tive problemas instalando diretamente no sistema, utilizando o brew. Algumas bibliotecas não eram encontradas e o trabalho para configuração de PATHs me fez migrar para pyenv.

brew install pyenv

Variaveis de ambiente

Para que as futuras compilações e instalações consigam encontrar todas as bibliotecas instaladas através do brew, é necessário configurar variáveis de ambiente para isso.

Adicione as linhas abaixo em seu arquivo de configuração do shell.

Se for bash: .bashrc Se for zsh: .zshrc

Eu fiz um script onde faz cache das chamadas do homebrew. Fique atento as versões das bibliotecas, se por ventura algumas delas não forem encontradas, confira o path das variaveis de ambiente.

Obs.: A melhor forma para obter o path das bibliotecas seria através do comando brew --prefix mas fazer inumeras chamadas pode deixar a inicialização do shell lenta.

Segue o que deve ser inserido em um dos arquivos acima:

if [ -z "$HOMEBREW_PREFIX" ]; then export PATH="/opt/homebrew/bin:$PATH" if command -v brew 1>/dev/null 2>&1; then SHELL_ENV="$(brew shellenv)" echo -n "$SHELL_ENV $(cat ~/.zshrc)" > .zshrc eval $SHELL_ENV fi fi export PATH="$HOMEBREW_PREFIX/opt/openssl@1.1/bin:$PATH" export LDFLAGS="-L/opt/homebrew/lib -L/opt/homebrew/opt/openssl@1.1/lib -L/opt/homebrew/opt/sqlite/lib -L/opt/homebrew/opt/python@3.8/lib -L/opt/homebrew/opt/libffi/lib -L/opt/homebrew/opt/openblas/lib -L/opt/homebrew/opt/lapack/lib -L/opt/homebrew/opt/zlib/lib -L/opt/homebrew/Cellar/bzip2/1.0.8/lib -L/opt/homebrew/opt/readline/lib" export CPPFLAGS="-I/opt/homebrew/include -I/opt/homebrew/opt/openssl@1.1/include -I/opt/homebrew/opt/sqlite/include -I/opt/homebrew/opt/libffi/include -I/opt/homebrew/opt/openblas/include -I/opt/homebrew/opt/lapack/include -I/opt/homebrew/opt/zlib/include -I/opt/homebrew/Cellar/bzip2/1.0.8/include -I/opt/homebrew/opt/readline/include" export PKG_CONFIG_PATH="$HOMEBREW_PREFIX/opt/openssl@1.1/lib/pkgconfig" export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:$HOMEBREW_PREFIX/opt/python@3.8/lib/pkgconfig:$HOMEBREW_PREFIX/opt/libffi/lib/pkgconfig:$HOMEBREW_PREFIX/opt/openblas/lib/pkgconfig:$HOMEBREW_PREFIX/opt/lapack/lib/pkgconfig:$HOMEBREW_PREFIX/opt/zlib/lib/pkgconfig" export GDAL_LIBRARY_PATH="/opt/homebrew/opt/gdal/lib/libgdal.dylib" export GEOS_LIBRARY_PATH=$GDAL_LIBRARY_PATH export LD_LIBRARY_PATH=$HOMEBREW_PREFIX/lib:$LD_LIBRARY_PATH export DYLD_LIBRARY_PATH=$HOMEBREW_PREFIX/lib:$DYLD_LIBRARY_PATH export OPENBLAS="$(brew --prefix openblas)" if command -v pyenv 1>/dev/null 2>&1; then eval "$(pyenv init -)" fi

Instalando Python 3 no M1

Para instalar o Python através do pipenv no m1 é necessário aplicar um patch para corrigir algumas informações da arquitetura.

O time do Homebrew disponibilizou esses patchs e pode ser localizado em: https://github.com/Homebrew/formula-patches/tree/master/python

Como estou instalando a versão 3.8, segue o comando:

PYTHON_CONFIGURE_OPTS="--with-openssl=$(brew --prefix openssl)" \ pyenv install --patch 3.8.7 <<(curl -sSL "https://raw.githubusercontent.com/Homebrew/formula-patches/master/python/3.8.7.patch")

NVM e Node no M1

mkdir ~/.nvm

Colocar no .zshrc ou .bashrc

export NVM_DIR="$HOME/.nvm" [ -s "/opt/homebrew/opt/nvm/nvm.sh" ] && . "/opt/homebrew/opt/nvm/nvm.sh" # This loads nvm [ -s "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" ] && . "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" # This loads nvm bash_completion

Fim da primeira parte:

Essa primeira parte mostrei como instalar o gerenciador de pacores, Python e Node. Irei fazer Posts sobre partes especificas como Android Studio, Xcode, Docker e etc.

Espero que me acompanhem e qualquer dúvida pode deixar o comentário.

Até mais

Homebrew will install a couple of packages required by Python and then Python itself. Now that you’ve got Homebrew installing Python is simple: brew install python See or type brew help or man brew for more info on Homebrew. Normal executables go in /usr/local/bin/ and Python scripts installed by Homebrew go in /usr/local/share/python/. bash_profile) file: export PATH=/usr/local/bin:/usr/local/share/python:$PATH To add Homebrew installed executables and Python scripts to your path you’ll want to add the following line to your.

#XCODE FOR MAC OS X 10.7.5 FOR MAC OS X#

Homebrew is an excellent package manager for Mac OS X that can install a large number of packages. (You’ll need a free Apple ID.) (See also. If you prefer another editor it’s possible to get only the libraries and compilers that you need with the Command Line Tools for Xcode. However, I use hardly any of its features and unless you’re an iOS or Mac developer you probably won’t either.

#XCODE FOR MAC OS X 10.7.5 CODE#

I use the Xcode editor because I like its syntax highlighting, code completion, and organizer. On Lion you can install Xcode from the App Store, on Snow Leopard you’ll have to get an older Xcode from. You will need Apple’s developer tools in order to compile Python and the other installs. Update: If doing all the stuff below doesn’t seem like your cup of tea, it’s also possible to install Python, NumPy, SciPy, and matplotlib using double-click binary installers (resulting in a much less flexible installation), see this post to learn how. On Snow Leopard you won’t install Xcode via the App Store, you’ll have to download it from Apple.Īfter I’d helped my friend I found this blog post describing a procedure pretty much the same as below. These instructions are for Lion but should work on Snow Leopard or Mountain Lion without much trouble. See the “Install Python” page for the most recent instructions.Ī bit ago a friend and I both had fresh Mac OS X Lion installs so I helped him set up his computers with a scientific Python setup and did mine at the same time. Update: These instructions are over a year old, though they may still work for you.

Setting the State of a Postgres Sequence.

You can work around the bug in Xcode 3.2.x by using the -k-no_order_inits command line parameter when compiling a dynamic library. There is however an issue when compiling dynamic libraries with FPC under Mac OS X 10.6 due to a bug in the Xcode 3.2.x linker. Xcode 3.2.x - 4.2 compatibility (Mac OS X 10.6)įPC 3.0.4 is qualified for use with Mac OS X 10.4 till macOS 10.14. Afterwards, FPC will install and function correctly. To install them manually, open Xcode, go to Preferences, select "Downloads" and install the "Command Line Tools". Xcode 4.3 and later however no longer install the command line tools by default, which are required by FPC. Xcode 4.3 - 5.x compatibility (Mac OS X 10.7/OS X 10.8)įPC 3.0.4 is qualified for use with Mac OS X 10.4 till macOS 10.14. To install them manually, open "/Applications/Utilities/Terminal", execute "xcode-select -install" and choose "Install". Xcode 5 and later however no longer install the command line tools by default, which are required by FPC. Xcode 5+ compatibility (OS X 10.9 for OS X 10.8, see below)įPC 3.0.4 is qualified for use with Mac OS X 10.4 till macOS 10.14.

#XCODE FOR MAC OS X 10.7.5 HOW TO#

See also the section below on how to install the command line tools. If you already installed FPC under a previous Mac OS X/OS X/macOS version, you will have to reinstall FPC 3.0.4a under macOS 10.14 to get a configuration file that enables the compiler to find the necessary files). Xcode 10 installs some command line file in different locations compared to previous releases. These workarounds are required because we do not pay Apple 79 euro per year, which would prove you can trust us.įPC 3.0.4 is qualified for use with Mac OS X 10.4 till macOS 10.14.

If this is not one of the most robust, free, rich and informative era ever then I cannot think of any other time in history adorned with the wealth of technology as this one. If you would wish to accomplish anything, this era wields the most virile grounds to nourish, nurture and aid the sprouting, the growth and the maturity of your dreams. You can literaly learn to be what you would wish to be in this age. That being said, this disquisition takes on a quest to get you into setting up something similar to Heroku on your own environment. We shall get to know what Heroku is then get off the dock and sail off towards our goal of having such an environment. The proliferation of cloud technologies brought with it many opportunities in terms of service offerings. First and foremost, users had the ability to get as much infrastructure as they could afford. Users can spawn servers, storage and network resources ad libitum which is popularly known as Infrastructure as a service. Then comes the second layer that sits on the infrastructure. It could be anything, cloud identity service, cloud monitoring server et cetera. This layer provides ready made solutions to people who might need them. This is known as software as a service. I hope we are flowing together this far. In addition to that there is another incredible layer that is the focus of this guide. It is a layer that targets developers majorly by making their lives easier on the cloud. In this layer , developers only concentrate on writing code and when they are ready to deploy, they only need to commit their ready project in a source control platform like GitHub/GitLab and the rest is done for them automatically. This layer provides a serverless layer to the developers since they do not have to touch the messy server side stuff. This layer as you might already have guessed is known as Platform as a Service (PaaS). Heroku is one of the solutions that sits on this layer. In this guide, are going to setup a platform that is similar to Heroku on your own infrastructure. As you know, you cannot download and install Heroku on your server. It is an online cloud service that you subscribe to. We will use Caprover to setup our own private Platform as a service (PaaS). CapRover is an extremely easy to use app/database deployment & web server manager for your NodeJS, Python, PHP, ASP.NET, Ruby, MySQL, MongoDB, Postgres, WordPress and even more applications. Features of Caprover CLI for automation and scripting Web GUI for ease of access and convenience No lock-in! Remove CapRover and your apps keep working! Docker Swarm under the hood for containerization and clustering Nginx (fully customizable template) under the hood for load-balancing Let’s Encrypt under the hood for free SSL (HTTPS) One-Click Apps: Deploying one-click apps is a matter of seconds! MongoDB, Parse, MySQL, WordPress, Postgres and many more. Fully Customizable: Optionally fully customizable nginx config allowing you to enable HTTP2, specific caching logic, custom SSL certs and etc Cluster Ready: Attach more nodes and create a cluster in seconds! CapRover automatically configures nginx to load balance. Increase Productivity: Focus on your apps! Not the bells and whistles just to run your apps! Easy Deploy: Many ways to deploy. You can upload your source from dashboard, use command line caprover deploy, use webhooks and build upon git push Caprover Pre-requisites Caprover runs as a container in your server which can be any that supports containerization. Depending on your preferences, you can use Podman or Docker to pull and run Caprover image. For this example, we are going to use Docker. In case you do not have Docker installed, the following guides listed below will be there to help you set it up as fast as possible. Install Docker and Docker Compose on Debian Setup Docker CE & Docker Compose on CentOS 8 | RHEL 8 How To Install Docker on RHEL 7 / CentOS 7

How To Install Docker CE on Ubuntu Once Docker Engine has been installed, add your user account to docker group: sudo usermod -aG docker $USER newgrp docker Another pre-requisite is a wildcard domain name pointed to the IP of your server where Caprover Server will be running. Setup your Heroku PaaS using CapRover Once the pre-requisites are out of the way, the only task remaining now is to set up our Caprover and poke around its rooms just to see what it has to offer. The following steps will be invaluable as you try to get it up and running. Step 1: Prepare your server Once Docker is installed, you can install all of the applications you need during your stay in the server. They include an editor and such kind of stuff. ##On CentOS sudo yum update sudo yum install vim git curl ##On Ubuntu sudo apt update sudo apt install vim git curl That was straingtforward. Next, let us pull Caprover image to set the stone rolling Step 2: Pull and execute Caprover Image We are going to cover the installation of Caprover depending on where your server sits. Scenario 1: Installation on a local server without Public IP Install dnsmasq After all, as mentioned in the pre-requisites section, we shall need a small DNS server to resolve domain names since Caprover is so particular with it. In case you have a local DNS server that supports wildcard domains, then you are good to go. You can skip the DNS setup part. In case you do not have it, install lightweight dnsmasq as follows: sudo yum -y install dnsmasq After dnsmasq is successfully installed, start and enable the service. sudo systemctl start dnsmasq sudo systemctl enable dnsmasq Add Wildcard DNS Recod Once dnsmasq is running as expected, we can go ahead and add the configs and wildcard domain name as shown below: $ sudo vim /etc/dnsmasq.conf listen-address=::1,127.0.0.1,172.20.192.38 domain=example.com server=8.8.8.8 address=/caprover.example.com/172.20.192.38 Replace the IPs therein with yours accordingly. Then restart dnsmasq sudo systemctl restart dnsmasq Test if it works We shall use the dig utility to test if our configuration works $ dig @127.0.0.1 test.caprover.example.com ; DiG 9.11.20-RedHat-9.11.20-5.el8 @127.0.0.1 test.caprover.example.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER> Checking System Compatibility > Checking System Compatibility

Hopefully, you see some of your own Postgres situation in my particular path, and you can hop on somewhere and get to your own solution. If I was just getting started or I didn’t care about losing that data, I likely would have blown everything away and run rails db:prepare and been up and running with Postgres 13. I went this route as I really wanted to hold on to the data I had in my local DBs.

BREW INSTALL POSTGRES 12 INSTALL

I’m really unsure of what state the install is in, and it’s likely to trip me up in the future if I don’t handle it here while I have this context in my hed. I should remove it or otherwise plan on upgrading my app to it.

Postgres 13 is still installed on my machine.

With this, I could restart Rails and get my app up and running again. A quick start kicked the service off brew services start It’s important to note that even though I had linked brew to the old postgres version, when I was running brew commands, I still needed to reference the appropriate brew Postgres install, hence the Next Steps I began by checking which brew services were running with brew services list. Running Postgresįinally, I had to restart Postgres. Checking the version through the terminal confirmed this. After fumbling with a few commands and various Stack Overflow posts, I discovered brew link -overwrite This pointed the postgres command at the latest version. It was allowing both to be installed on my machine. Homebrew wasn’t installing the old version of Postgres over the existing 13.x. But checking the postgres version still returned the new Postgres install. brew install the old version my app was expecting onto my machine. Installing the older version of Postgres wasn’t too bad. I needed to install 12.x and then point homebrew at the install. The best way to do that would be to walk my local copy back to 12.x. I want to minimize the surface area and variables between known working versions of my software. I’m a believer in intentional upgrades and intentional changes.

Bring my install up to the latest, 13.x or.

Next, I check the version with postgres -version and I get back 13.x which is not the 12.x I expected. With a quick command in the terminal, which postgres, I see that it’s installed in /usr/local/bin which I know is where homebrew installs.

In this case, I know that Postgres can be installed a number of different ways, and I want to verify how the software is installed. When I get stuck, I take a deep breath and gather up my assumptions. And which version of Postgres am I running?.Which install of Postgres am I running?.I then when through my typical debugging questions: I rushed through my typical fix of deleting the postmaster.pid which usually gets left behind when my machine restarts only to find that this can cause worse problems when done incorrectly. Here’s my particular breadcrumb trail.Īfter starting my local Rails server after the OSX upgrade, I was greeted with the dreaded error “connection to database failed: could not connect to server: No such file or directory”. After flailing and staring at countless Stack Overflow threads, I found my way out of the woods. This is pretty typical for me after OS updates the feedback loop between updates is too long for my memory. Traversing array in a loop with a loop variable and range is quite redundant it is only needed when the range is calculated and not the same as the array range otherwise for-in loop should be used.I recently ran into an issue with Postgres after upgrading to Big Sur. If a JSON key uses invalid JSONPath characters, then you can escape those characters using single quotes and brackets. each () is a generic iterator function for looping over object, arrays, and array-like objects.
