Azure CLI via Podman (Docker)

#TIL when you're running the azure cli (az) via podman (like docker, but not run via root owned service), that the -t switch is your enemy.

-t joins the output of STDOUT and STDERR, and thus can result in the output of your command containing extra control characters, in particular this means it can contain the \r control character. this makes processing the results in a bash script EXTREMELY difficult.

the -t switch DOES clearly document this, but who reads documentation

NOTE: The --tty flag prevents redirection of standard output. It combines STDOUT and STDERR, it can insert control characters, and it can hang pipes. This option is only used when run interactively in a terminal. When feeding input to Podman, use -i only, not -it.

Man goes to the doctor. Says he's frustrated. Says his Python experience seems complicated and confusing. Says he feels there are too many environment and package management system options and he doesn't know what to do.

Doctor says, "Treatment is simple. Just use Poetry + pyenv, which combines the benefits of conda, venv, pip, and virtualenv. But remember, after setting up your environment, you'll need to install build essentials, which aren't included out-of-the-box. So, upgrade pip, setuptools, and wheel immediately. Then, you'll want to manage your dependencies with a pyproject.toml file.

"Of course, Poetry handles dependencies, but you may need to adjust your PATH and activate pyenv every time you start a new session. And don't forget about locking your versions to avoid conflicts! And for data science, you might still need conda for some specific packages.

"Also, make sure to use pipx for installing CLI tools globally, but isolate them from your project's environment. And if you're deploying, Dockerize your app to ensure consistency across different machines. Just be cautious about Docker’s compatibility with M1 chips.

"Oh, and when working with Jupyter Notebooks, remember to install ipykernel within your virtual environment to register your kernel. But for automated testing, you should...

Unleashing Efficiency: Containerization with Docker

Introduction: In the fast-paced world of modern IT, agility and efficiency reign supreme. Enter Docker - a revolutionary tool that has transformed the way applications are developed, deployed, and managed. Containerization with Docker has become a cornerstone of contemporary software development, offering unparalleled flexibility, scalability, and portability. In this blog, we'll explore the fundamentals of Docker containerization, its benefits, and practical insights into leveraging Docker for streamlining your development workflow.

Understanding Docker Containerization: At its core, Docker is an open-source platform that enables developers to package applications and their dependencies into lightweight, self-contained units known as containers. Unlike traditional virtualization, where each application runs on its own guest operating system, Docker containers share the host operating system's kernel, resulting in significant resource savings and improved performance.

Key Benefits of Docker Containerization:

Portability: Docker containers encapsulate the application code, runtime, libraries, and dependencies, making them portable across different environments, from development to production.

Isolation: Containers provide a high degree of isolation, ensuring that applications run independently of each other without interference, thus enhancing security and stability.

Scalability: Docker's architecture facilitates effortless scaling by allowing applications to be deployed and replicated across multiple containers, enabling seamless horizontal scaling as demand fluctuates.

Consistency: With Docker, developers can create standardized environments using Dockerfiles and Docker Compose, ensuring consistency between development, testing, and production environments.

Speed: Docker accelerates the development lifecycle by reducing the time spent on setting up development environments, debugging compatibility issues, and deploying applications.

Getting Started with Docker: To embark on your Docker journey, begin by installing Docker Desktop or Docker Engine on your development machine. Docker Desktop provides a user-friendly interface for managing containers, while Docker Engine offers a command-line interface for advanced users.

Once Docker is installed, you can start building and running containers using Docker's command-line interface (CLI). The basic workflow involves:

Writing a Dockerfile: A text file that contains instructions for building a Docker image, specifying the base image, dependencies, environment variables, and commands to run.

Building Docker Images: Use the docker build command to build a Docker image from the Dockerfile.

Running Containers: Utilize the docker run command to create and run containers based on the Docker images.

Managing Containers: Docker provides a range of commands for managing containers, including starting, stopping, restarting, and removing containers.

Best Practices for Docker Containerization: To maximize the benefits of Docker containerization, consider the following best practices:

Keep Containers Lightweight: Minimize the size of Docker images by removing unnecessary dependencies and optimizing Dockerfiles.

Use Multi-Stage Builds: Employ multi-stage builds to reduce the size of Docker images and improve build times.

Utilize Docker Compose: Docker Compose simplifies the management of multi-container applications by defining them in a single YAML file.

Implement Health Checks: Define health checks in Dockerfiles to ensure that containers are functioning correctly and automatically restart them if they fail.

Secure Containers: Follow security best practices, such as running containers with non-root users, limiting container privileges, and regularly updating base images to patch vulnerabilities.

Conclusion: Docker containerization has revolutionized the way applications are developed, deployed, and managed, offering unparalleled agility, efficiency, and scalability. By embracing Docker, developers can streamline their development workflow, accelerate the deployment process, and improve the consistency and reliability of their applications. Whether you're a seasoned developer or just getting started, Docker opens up a world of possibilities, empowering you to build and deploy applications with ease in today's fast-paced digital landscape.

Why Building and Deploying Matters

Building and deploying are the final steps of the development lifecycle. Building compiles your Angular project into static files, while deploying makes it accessible to users on a server. Proper optimization and configuration ensure faster load times and better performance.

Preparing Your Angular 19 App for Production

Before building the application, make sure to:

Update Angular CLI: Keep your Angular CLI up to date.

npm install -g @angular/cli

Optimize Production Build: Enable AOT compilation and minification.

Environment Configuration: Use the correct environment variables for production.

Building Angular 19 App

To create a production build, run the following command:

ng build --configuration=production

This command generates optimized files in the dist/ folder.

Key Optimizations in Production Build:

AOT Compilation: Reduces bundle size by compiling templates during the build.

Tree Shaking: Removes unused modules and functions.

Minification: Compresses HTML, CSS, and JavaScript files.

Source Map Exclusion: Disables source maps for production builds to improve security and reduce file size.

Configuration Example:

Modify the angular.json file to customize production settings:

"configurations": "production": "optimization": true, "outputHashing": "all", "sourceMap": false, "namedChunks": false, "extractCss": true, "aot": true, "fileReplacements": [ "replace": "src/environments/environment.ts", "with": "src/environments/environment.prod.ts" ]

    Deploying Angular 19 App

Deployment options for Angular apps include:

Static Web Servers (e.g., NGINX, Apache)

Cloud Platforms (e.g., AWS S3, Firebase Hosting)

Docker Containers

Serverless Platforms (e.g., AWS Lambda)

Deploying on Firebase Hosting

Install Firebase CLI:

npm install -g firebase-tools

Login to Firebase:

firebase login

Initialize Firebase Project:

firebase init hosting

Deploy the App:

firebase deploy

Deploying on AWS S3 and CloudFront

Build the Project:

ng build --configuration=production

Upload to S3:

aws s3 sync ./dist/my-app s3://my-angular-app

Configure CloudFront Distribution: Set the S3 bucket as the origin.

Automating Deployment with CI/CD

Setting up a CI/CD pipeline ensures seamless updates and faster deployments.

Example with GitHub Actions

Create a .github/workflows/deploy.yml file:

name: Deploy Angular App on: [push] jobs: build-and-deploy: runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - name: Set up Node.js uses: actions/setup-node@v2 with: node-version: '18' - run: npm install - run: npm run build -- --configuration=production - name: Deploy to S3 run: aws s3 sync ./dist/my-app s3://my-angular-app --delete

Best Practices for Building and Deploying Angular 19 Apps

Optimize for Production: Always use AOT and minification.

Use CI/CD Pipelines: Automate the build and deployment process.

Monitor Performance: Utilize tools like Lighthouse to analyze performance.

Secure the Application: Enable HTTPS and configure secure headers.

Cache Busting: Use hashed filenames to avoid caching issues.

Containerize with Docker: Simplifies deployments and scales easily.

Postal SMTP install and setup on a virtual server

Postal is a full suite for mail delivery with robust features suited for running a bulk email sending SMTP server. Postal is open source and free. Some of its features are: - UI for maintaining different aspects of your mail server - Runs on containers, hence allows for up and down horizontal scaling - Email security features such as spam and antivirus - IP pools to help you maintain a good sending reputation by sending via multiple IPs - Multitenant support - multiple users, domains and organizations - Monitoring queue for outgoing and incoming mail - Built in DNS setup and monitoring to ensure mail domains are set up correctly List of full postal features

Possible cloud providers to use with Postal

You can use Postal with any VPS or Linux server providers of your choice, however here are some we recommend: Vultr Cloud (Get free $300 credit) - In case your SMTP port is blocked, you can contact Vultr support, and they will open it for you after providing a personal identification method. DigitalOcean (Get free $200 Credit) - You will also need to contact DigitalOcean support for SMTP port to be open for you. Hetzner ( Get free €20) - SMTP port is open for most accounts, if yours isn't, contact the Hetzner support and request for it to be unblocked for you Contabo (Cheapest VPS) - Contabo doesn't block SMTP ports. In case you are unable to send mail, contact support. Interserver

Postal Minimum requirements

- At least 4GB of RAM - At least 2 CPU cores - At least 25GB disk space - You can use docker or any Container runtime app. Ensure Docker Compose plugin is also installed. - Port 25 outbound should be open (A lot of cloud providers block it)

Postal Installation

Should be installed on its own server, meaning, no other items should be running on the server. A fresh server install is recommended. Broad overview of the installation procedure - Install Docker and the other needed apps - Configuration of postal and add DNS entries - Start Postal - Make your first user - Login to the web interface to create virtual mail servers Step by step install Postal Step 1 : Install docker and additional system utilities In this guide, I will use Debian 12 . Feel free to follow along with Ubuntu. The OS to be used does not matter, provided you can install docker or any docker alternative for running container images. Commands for installing Docker on Debian 12 (Read the comments to understand what each command does): #Uninstall any previously installed conflicting software . If you have none of them installed it's ok for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done #Add Docker's official GPG key: sudo apt-get update sudo apt-get install ca-certificates curl -y sudo install -m 0755 -d /etc/apt/keyrings sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc sudo chmod a+r /etc/apt/keyrings/docker.asc #Add the Docker repository to Apt sources: echo "deb https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null sudo apt-get update #Install the docker packages sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y #You can verify that the installation is successful by running the hello-world image sudo docker run hello-world Add the current user to the docker group so that you don't have to use sudo when not logged in as the root user. ##Add your current user to the docker group. sudo usermod -aG docker $USER #Reboot the server sudo reboot Finally test if you can run docker without sudo ##Test that you don't need sudo to run docker docker run hello-world Step 2 : Get the postal installation helper repository The Postal installation helper has all the docker compose files and the important bootstrapping tools needed for generating configuration files. Install various needed tools #Install additional system utlities apt install git vim htop curl jq -y Then clone the helper repository. sudo git clone https://github.com/postalserver/install /opt/postal/install sudo ln -s /opt/postal/install/bin/postal /usr/bin/postal Step 3 : Install MariaDB database Here is a sample MariaDB container from the postal docs. But you can use the docker compose file below it. docker run -d --name postal-mariadb -p 127.0.0.1:3306:3306 --restart always -e MARIADB_DATABASE=postal -e MARIADB_ROOT_PASSWORD=postal mariadb Here is a tested mariadb compose file to run a secure MariaDB 11.4 container. You can change the version to any image you prefer. vi docker-compose.yaml services: mariadb: image: mariadb:11.4 container_name: postal-mariadb restart: unless-stopped environment: MYSQL_ROOT_PASSWORD: ${DB_ROOT_PASSWORD} volumes: - mariadb_data:/var/lib/mysql network_mode: host # Set to use the host's network mode security_opt: - no-new-privileges:true read_only: true tmpfs: - /tmp - /run/mysqld healthcheck: test: interval: 30s timeout: 10s retries: 5 volumes: mariadb_data: You need to create an environment file with the Database password . To simplify things, postal will use the root user to access the Database.env file example is below. Place it in the same location as the compose file. DB_ROOT_PASSWORD=ExtremelyStrongPasswordHere Run docker compose up -d and ensure the database is healthy. Step 4 : Bootstrap the domain for your Postal web interface & Database configs First add DNS records for your postal domain. The most significant records at this stage are the A and/or AAAA records. This is the domain where you'll be accessing the postal UI and for simplicity will also act as the SMTP server. If using Cloudflare, turn off the Cloudflare proxy. sudo postal bootstrap postal.yourdomain.com The above will generate three files in /opt/postal/config. - postal.yml is the main postal configuration file - signing.key is the private key used to sign various things in Postal - Caddyfile is the configuration for the Caddy web server Open /opt/postal/config/postal.yml and add all the values for DB and other settings. Go through the file and see what else you can edit. At the very least, enter the correct DB details for postal message_db and main_db. Step 5 : Initialize the Postal database and create an admin user postal initialize postal make-user If everything goes well with postal initialize, then celebrate. This is the part where you may face some issues due to DB connection failures. Step 6 : Start running postal # run postal postal start #checking postal status postal status # If you make any config changes in future you can restart postal like so # postal restart Step 7 : Proxy for web traffic To handle web traffic and ensure TLS termination you can use any proxy server of your choice, nginx, traefik , caddy etc. Based on Postal documentation, the following will start up caddy. You can use the compose file below it. Caddy is easy to use and does a lot for you out of the box. Ensure your A records are pointing to your server before running Caddy. docker run -d --name postal-caddy --restart always --network host -v /opt/postal/config/Caddyfile:/etc/caddy/Caddyfile -v /opt/postal/caddy-data:/data caddy Here is a compose file you can use instead of the above docker run command. Name it something like caddy-compose.yaml services: postal-caddy: image: caddy container_name: postal-caddy restart: always network_mode: host volumes: - /opt/postal/config/Caddyfile:/etc/caddy/Caddyfile - /opt/postal/caddy-data:/data You can run it by doing docker compose -f caddy-compose.yaml up -d Now it's time to go to the browser and login. Use the domain, bootstrapped earlier. Add an organization, create server and add a domain. This is done via the UI and it is very straight forward. For every domain you add, ensure to add the DNS records you are provided.

Enable IP Pools

One of the reasons why Postal is great for bulk email sending, is because it allows for sending emails using multiple IPs in a round-robin fashion. Pre-requisites - Ensure the IPs you want to add as part of the pool, are already added to your VPS/server. Every cloud provider has a documentation for adding additional IPs, make sure you follow their guide to add all the IPs to the network. When you run ip a , you should see the IP addresses you intend to use in the pool. Enabling IP pools in the Postal config First step is to enable IP pools settings in the postal configuration, then restart postal. Add the following configuration in the postal.yaml (/opt/postal/config/postal.yml) file to enable pools. If the section postal: , exists, then just add use_ip_pools: true under it. postal: use_ip_pools: true Then restart postal. postal stop && postal start The next step is to go to the postal interface on your browser. A new IP pools link is now visible at the top right corner of your postal dashboard. You can use the IP pools link to add a pool, then assign IP addresses in the pools. A pool could be something like marketing, transactions, billing, general etc. Once the pools are created and IPs assigned to them, you can attach a pool to an organization. This organization can now use the provided IP addresses to send emails. Open up an organization and assign a pool to it. Organizations → choose IPs → choose pools . You can then assign the IP pool to servers from the server's Settings page. You can also use the IP pool to configure IP rules for the organization or server. At any point, if you are lost, look at the Postal documentation. Read the full article

Deploying Containers on AWS ECS with Fargate

Introduction

Amazon Elastic Container Service (ECS) with AWS Fargate enables developers to deploy and manage containers without managing the underlying infrastructure. Fargate eliminates the need to provision or scale EC2 instances, providing a serverless approach to containerized applications.

This guide walks through deploying a containerized application on AWS ECS with Fargate using AWS CLI, Terraform, or the AWS Management Console.

1. Understanding AWS ECS and Fargate

✅ What is AWS ECS?

Amazon ECS (Elastic Container Service) is a fully managed container orchestration service that allows running Docker containers on AWS.

✅ What is AWS Fargate?

AWS Fargate is a serverless compute engine for ECS that removes the need to manage EC2 instances, providing:

Automatic scaling

Per-second billing

Enhanced security (isolation at the task level)

Reduced operational overhead

✅ Why Choose ECS with Fargate?

✔ No need to manage EC2 instances ✔ Pay only for the resources your containers consume ✔ Simplified networking and security ✔ Seamless integration with AWS services (CloudWatch, IAM, ALB)

2. Prerequisites

Before deploying, ensure you have:

AWS Account with permissions for ECS, Fargate, IAM, and VPC

AWS CLI installed and configured

Docker installed to build container images

An existing ECR (Elastic Container Registry) repository

3. Steps to Deploy Containers on AWS ECS with Fargate

Step 1: Create a Dockerized Application

First, create a simple Dockerfile for a Node.js or Python application.

Example: Node.js DockerfiledockerfileFROM node:16-alpine WORKDIR /app COPY package.json . RUN npm install COPY . . CMD ["node", "server.js"] EXPOSE 3000

Build and push the image to AWS ECR:shaws ecr create-repository --repository-name my-app docker build -t my-app . docker tag my-app:latest <AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/my-app:latest aws ecr get-login-password --region <REGION> | docker login --username AWS --password-stdin <AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com docker push <AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/my-app:latest

Step 2: Create an ECS Cluster

Use the AWS CLI to create a cluster:shaws ecs create-cluster --cluster-name my-cluster

Or use Terraform:hclresource "aws_ecs_cluster" "my_cluster" { name = "my-cluster" }

Step 3: Define a Task Definition for Fargate

The task definition specifies how the container runs.

Create a task-definition.js{ "family": "my-task", "networkMode": "awsvpc", "executionRoleArn": "arn:aws:iam::<AWS_ACCOUNT_ID>:role/ecsTaskExecutionRole", "cpu": "512", "memory": "1024", "requiresCompatibilities": ["FARGATE"], "containerDefinitions": [ { "name": "my-container", "image": "<AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/my-app:latest", "portMappings": [{"containerPort": 3000, "hostPort": 3000}], "essential": true } ] }

Register the task definition:shaws ecs register-task-definition --cli-input-json file://task-definition.json

Step 4: Create an ECS Service

Use AWS CLI:shaws ecs create-service --cluster my-cluster --service-name my-service --task-definition my-task --desired-count 1 --launch-type FARGATE --network-configuration "awsvpcConfiguration={subnets=[subnet-xyz],securityGroups=[sg-xyz],assignPublicIp=\"ENABLED\"}"

Or Terraform:hclresource "aws_ecs_service" "my_service" { name = "my-service" cluster = aws_ecs_cluster.my_cluster.id task_definition = aws_ecs_task_definition.my_task.arn desired_count = 1 launch_type = "FARGATE" network_configuration { subnets = ["subnet-xyz"] security_groups = ["sg-xyz"] assign_public_ip = true } }

Step 5: Configure a Load Balancer (Optional)

If the service needs internet access, configure an Application Load Balancer (ALB).

Create an ALB in your VPC.

Add an ECS service to the target group.

Configure a listener rule for routing traffic.

4. Monitoring & Scaling

🔹 Monitor ECS Service

Use AWS CloudWatch to monitor logs and performance.shaws logs describe-log-groups

🔹 Auto Scaling ECS Tasks

Configure an Auto Scaling Policy:sh aws application-autoscaling register-scalable-target \ --service-namespace ecs \ --scalable-dimension ecs:service:DesiredCount \ --resource-id service/my-cluster/my-service \ --min-capacity 1 \ --max-capacity 5

5. Cleaning Up Resources

After testing, clean up resources to avoid unnecessary charges.shaws ecs delete-service --cluster my-cluster --service my-service --force aws ecs delete-cluster --cluster my-cluster aws ecr delete-repository --repository-name my-app --force

Conclusion

AWS ECS with Fargate simplifies container deployment by eliminating the need to manage servers. By following this guide, you can deploy scalable, cost-efficient, and secure applications using serverless containers.
