No issues to report. It's shaping up to be +a great release. + +I've been looking for a suitable [Docker][] replacement for a few years +because of [their repeated license shenanigans][license-shenanigans]. +Last year I tried switching to [Podman][], but ran into into several +incompatibilities and minor annoyances. + +[Podman 4.3][podman-4.3] ships with [Bookworm][] and seems to fix all +the issues I had before. [Rootless containers][], [multi-stage +builds][multi-stage], and all of my muscle-memory `docker` commands now +work as expected. + +The only real differences I noticed are: + +1. The command is `podman` instead of `docker`. +2. Image names are registry-prefixed. Example: `FROM docker.io/bash` instead of `FROM bash`. +3. Searches are registry-prefixed. Example: `podman search docker.io/pablotron`. + +A couple of quick tests: + +* [Sinatra web application (rootless)][sinatra-test] +* [Go web application (rootless, scratch, multi-stage build)][go-test] + +[bookworm]: https://www.debian.org/releases/bookworm/ + "Debian bookworm." +[debian]: https://debian.org/ + "Debian Linux." +[docker]: https://www.docker.com/ + "Docker container manager." +[podman]: https://podman.io/ + "Podman container manager." +[podman-4.3]: https://podman.io/releases/2022/10/22/podman-release-v4.3.0.html + "Podman version 4.3." +[rootless containers]: https://developers.redhat.com/blog/2020/09/25/rootless-containers-with-podman-the-basics + "Rootless containers." +[multi-stage]: https://docs.docker.com/build/building/multi-stage/ + "Multi-stage build." +[sinatra-test]: https://gist.github.com/pablotron/86cb0b355ac3e4cef3b28b3e0718314d + "Test Sinatra web application running in a Podman container." +[go-test]: https://gist.github.com/pablotron/03785b66cc9e90ebd5fdaef5642baa6d + "Test Go web application running in a Podman container." +[license-shenanigans]: https://blog.alexellis.io/docker-is-deleting-open-source-images/ + "Docker is deleting Open Source organizations (updated)." |
