What about raw systemd? It can do resource control, service monitoring and restart and seems pretty lightweight compared to Docker. Fewer ways to footgun with data being erased, no separate shells or finding a tool you need isn't available inside the container.
Or, you could use a distro with a sane init system, which eliminates all the systemd and reinvented wheel footguns.
The last time I installed ubuntu 18.04, DNS queries took ~5 seconds. It’s a well known issue, with no diagnosed root cause. The solutions involved uninstalling the local dns stack, starting with systemd’s resolver.
2018 was well after DNS was reliable. How can stuff like that break in a long term support release?
Which is ironic because systemd got a lot of hate for doing the right thing and not just querying DNS servers in order but discovering the remembering the servers that are up/fastest.
Turns out a lot of people just ignored the fact that all configured DNS servers are assumed to serve the same records and used DNS ordering to implement shitty split-horizon DNS.
