okay so i discovered my first major limitation of pluug: I/O bottleneck. transfer over ftp sits around 300KB/s while transmission is active, but i paused it and so far it's climbed to 727 and is still increasing at a steady rate.

this is a good example why i'm not using him as a media server, just for the the actual torrenting. like i can manually manage stuff for now but later i can automate transmission's snail mode and provide a window to autocopy anything new over to my NAS/mediaserver

I have been using Btrfs for several months, and it has been stable enough for me. It is a file system that can be used as a storage driver for Linux containers like LXD, Incus, or Docker. If you want to install Btrfs support on Debian Linux and format & mount a disk drive, see my tutorial

Ansible Collections: Extending Ansible’s Capabilities

Ansible is a powerful automation tool used for configuration management, application deployment, and task automation. One of the key features that enhances its flexibility and extensibility is the concept of Ansible Collections. In this blog post, we'll explore what Ansible Collections are, how to create and use them, and look at some popular collections and their use cases.

Introduction to Ansible Collections

Ansible Collections are a way to package and distribute Ansible content. This content can include playbooks, roles, modules, plugins, and more. Collections allow users to organize their Ansible content and share it more easily, making it simpler to maintain and reuse.

Key Features of Ansible Collections:

Modularity: Collections break down Ansible content into modular components that can be independently developed, tested, and maintained.

Distribution: Collections can be distributed via Ansible Galaxy or private repositories, enabling easy sharing within teams or the wider Ansible community.

Versioning: Collections support versioning, allowing users to specify and depend on specific versions of a collection. How to Create and Use Collections in Your Projects

Creating and using Ansible Collections involves a few key steps. Here’s a guide to get you started:

1. Setting Up Your Collection

To create a new collection, you can use the ansible-galaxy command-line tool:

ansible-galaxy collection init my_namespace.my_collection

This command sets up a basic directory structure for your collection:

my_namespace/

└── my_collection/

├── docs/

├── plugins/

│ ├── modules/

│ ├── inventory/

│ └── ...

├── roles/

├── playbooks/

├── README.md

└── galaxy.yml

2. Adding Content to Your Collection

Populate your collection with the necessary content. For example, you can add roles, modules, and plugins under the respective directories. Update the galaxy.yml file with metadata about your collection.

3. Building and Publishing Your Collection

Once your collection is ready, you can build it using the following command:

ansible-galaxy collection build

This command creates a tarball of your collection, which you can then publish to Ansible Galaxy or a private repository:

ansible-galaxy collection publish my_namespace-my_collection-1.0.0.tar.gz

4. Using Collections in Your Projects

To use a collection in your Ansible project, specify it in your requirements.yml file:

collections:

- name: my_namespace.my_collection

version: 1.0.0

Then, install the collection using:

ansible-galaxy collection install -r requirements.yml

You can now use the content from the collection in your playbooks:--- - name: Example Playbook hosts: localhost tasks: - name: Use a module from the collection my_namespace.my_collection.my_module: param: value

Popular Collections and Their Use Cases

Here are some popular Ansible Collections and how they can be used:

1. community.general

Description: A collection of modules, plugins, and roles that are not tied to any specific provider or technology.

Use Cases: General-purpose tasks like file manipulation, network configuration, and user management.

2. amazon.aws

Description: Provides modules and plugins for managing AWS resources.

Use Cases: Automating AWS infrastructure, such as EC2 instances, S3 buckets, and RDS databases.

3. ansible.posix

Description: A collection of modules for managing POSIX systems.

Use Cases: Tasks specific to Unix-like systems, such as managing users, groups, and file systems.

4. cisco.ios

Description: Contains modules and plugins for automating Cisco IOS devices.

Use Cases: Network automation for Cisco routers and switches, including configuration management and backup.

5. kubernetes.core

Description: Provides modules for managing Kubernetes resources.

Use Cases: Deploying and managing Kubernetes applications, services, and configurations.

Conclusion

Ansible Collections significantly enhance the modularity, distribution, and reusability of Ansible content. By understanding how to create and use collections, you can streamline your automation workflows and share your work with others more effectively. Explore popular collections to leverage existing solutions and extend Ansible’s capabilities in your projects.

i think my job should give me a raise and theyre probably not going to bc we got our asses kicked in the latest funding round but they ARE giving me a $10k “please dont leave” bonus, which (as my mom might say) is certainly better than a poke in the eye with a sharp stick

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.
