Bump unbounded to v0.18.0 - #410
Merged

Conversation
v0.18.0 brings Azure/unbounded#962, which stops preflight warning that docker-active's and kubelet-active's service state "could not be determined" on every host where the service isn't running, and #967, which lets the agent supply the nspawn lifecycle hooks' commands instead of the helper unbounded copies onto the host. Nothing here supplies them yet. It also has NVIDIA nspawn nodes use the CDI runtime (#975). No code changes are needed.
…n it The move to the host root installs the nspawn lifecycle helper before it rewrites the active machine's hooks. With unbounded v0.18.0 a machine's config can supply the hooks' commands, and then its hooks don't run the helper. EnsureNSpawnLifecycleHelperFor installs it only for a machine whose hooks run it, as EnsureNSpawnConfig expects, so the move doesn't put a helper back on a host whose config supplies the commands. Until one does, nothing changes.

github.com/Azure/unboundedfrom v0.16.0 to v0.18.0. Onlygolang.org/xmodules move with it, and unbounded's minimum Go is still 1.26.10.For the agent, v0.18.0 brings:
docker-activeandkubelet-activechecks no longer warn that the service's state "could not be determined" on every host where the service isn't running, Ubuntu included.It builds without code changes. One follows from #967: the move to the host root installs the helper with
EnsureNSpawnLifecycleHelperFor, rather thanEnsureNSpawnLifecycleHelper. That way the move doesn't put a helper back on a host whose config supplies the hooks' commands. Until a config does, it installs the helper as before.Testing
