If you developed modern CI/CD pipelines you probably stumbled on the need to auto tag releases with semantic versions. Today I’ll show how to do that automatically and which tools may help to achieve automatic tagging releases with semantic versions.
Today, I’ll show how to create Kubernetes cluster on Linode using CLI. It might be useful, for instance, for CI/CD, automation processes, etc…
Today, I’ll show how to create and use Kubernetes operator using Ansible. I’ll also explain why to use Kubernetes operators and their relation to Kubernetes CRDs. As always, I’ll show a demo.

Migration from Jenkins to GitLab
Have you considered migration from Jenkins to GitLab? While working on CI/CD pipelines in Jenkins, you probably didn’t like coding them in Groovy. You wondered if any simpler CI/CD platform exists where you just have to worry about what commands to run in the pipelines. We’ll review important things to consider while planning migration from Jenkins to GitLab.
Jenkins docs suggest several ways to backup Jenkins home data. One of the easiest and mysterious ones is using file system snapshots. Luckily there’s a great tool – Kopia which I’ll demo today. We’ll backup Jenkins controller’s data to S3 bucket on the cloud.
In the last article we saw how to run Jenkins Docker in Docker Agent. In addition to its obvious use case of building and pushing Docker images, I also noted that such an agent allows to run minikube inside. Today, I’ll show how to run minikube in Docker container. Of course, we’ll use docker in docker client and daemon images for that.

Jenkins Docker in Docker Agent
So you installed Jenkins helm chart on Kubernetes cluster. Now you want to build Docker images. How would you do that? There are several ways. Today, we’ll focus on creating and using Jenkins Docker in Docker agent for that purpose.
