In the help docs it says Migration is still in experimental stages and may not work for all workloads is there any more info on this? Examples when it works, when it doesnt? is it worth relying on this etc.
Thanks.
Pretty much only works if you’re in full control of everything in the container.
Recent versions of systemd for the init system in the container usually prevent live migration, as does many of the modern daemons that may be running in there.
Some network options can also get in the way of live migration.
Our most minimal, known good test case is a an Alpine Linux container with no network interfaces, that works very reliably but is also pretty useless.
