Shameless plug: I wrote undocker[1] to convert docker images to a rootfs tarball, so I can run them with plain systemd. Goal: no more daemons to run 3rd party containers, systemd is good enough by now: resource limits, isolation, chroot, dynamic users, logging, and more. Low-level tooling is done, I am now building ecosystem around it: easy installation, convert to deb/rpm, systemd units, etc. [1]: https://sr.ht/~mot…
Been using systemd for personal project deployments for quite a while now after leaving ZEIT (Vercel) and the year or so fighting endlessly with k8s and docker's shortcomings. I love it. It does everything I need it to, it's fast, decently documented, supports everything Docker does (just not 1:1 in terms of DX) and is present wherever I need it.
I'm considering them for an upcoming project.
