Containerization related articles about Docker and Podman
Podman’s integration with Kubernetes through the podman kube play command allows users to create pods, containers, and volumes from Kubernetes YAML files. This command reads the structured file and recreates the described resources, starting the containers within a pod and outputting the ID of the new pod or the name of the new volume.
Sometimes you must create your own Podman images. Building your own Podman images allows for greater customization, control, consistency, and organizational efficiency compared to using only public images. The investment upfront can pay dividends in the long run through improved security, consistency, and maintainability of your container infrastructure.

Podman-compose is a script that simplifies the use of Podman to manage multi-container setups. It interprets the docker-compose.yml file and creates a Podman-compatible setup. This means you can use your existing Docker Compose files with Podman, making the transition smoother if you’re moving from Docker to Podman.
Podman volumes allow you to persist data outside of the container’s file system. This is particularly important when you need to ensure that your application data is not lost when a container is stopped, restarted, or removed. In this lesson you will learn the basics of managing Podman volumes in the command line.

Jenkins is a platform for creating a Continuous Integration/Continuous Delivery (CI/CD) environment. It is written in Java and provides support for various version control tools such as Git, running Bash scripts and Windows batch files, building Ant and Apache Maven-based projects, and more. Jenkins helps build, test, and continually deploy software. It is an open-source system and one of the leading automation servers. Jenkins requires scripting some automation steps, but it provides a fast and robust way to systematize the software development lifecycle. The program runs web containers and plugins, such as Apache Tomcat, and helps manage lifecycle and access rights requests. Over 1700 plugins for Jenkins enrich the software integration, automation, and delivery processes and provide a customizable environment. Jenkins is used for the whole software delivery pipeline, including deployment.
