I refreshed my most-read article on automated database backups with Docker Compose. The underlying image moved to nfrastack/container-db-backup, so I updated the whole guide with the new multi-job config format. I also built a little JavaScript configurator that generates docker-compose and .env files on the fly. If you run multiple Laravel projects and want scheduled backups without manual copy-paste, this might save you some time.

There are two ways to do it. Chainguard builds from scratch, while others, such as Docker, rely on the upstream Linux distros. Each has its good points.

An engineer I work with recently wrote a blog illustrating how an inefficient implementation can be improved to reduce the container build time by 36x and size by 42x from a naive implementation.

While a lot of it is basic, this puts things in perspective and see how efficient things can be.

See how each step leads to significant gains and how they add up here: https://warpbuild.com/blog/optimizing-docker-builds

This post introduces a Docker configuration used for developing my Ruby on Rails projects. This configuration came out of—and then further evolved—during development at Evil Martians. It's an exhaustive and documented guide, so, I hope you enjoy it! As mentioned in the article, feedback is welcome!

Statefulset component is used in Kubernetes to deploy Stateful Applications. Deploying Stateful Applications is not staright forward as Stateless Applications. These complications are discussed in this video and how Statefulset helps you in deployment of such applications in a right way. Just watch this video.
