If we get an error we'll only hold the deploy lock if it occurs while
trying to switch the running containers.
We'll also move tagging the latest image from when the image is pulled
to just before the container switch. This ensures that earlier errors
don't leave the hosts with an updated latest tag while still running the
older version.
When deploying check if there is already a container with the existing
name. If there is rename it to "<version>_<random_hex_string>" to remove
the name clash with the new container we want to boot.
We can then do the normal zero downtime run/wait/stop.
While implementing this I discovered the --filter name=foo does a
substring match for foo, so I've updated those filters to do an exact
match instead.
* main:
Wording
Remove accessory images using tags rather than labels
Update readme to point to ghcr.io/mrsked/mrsk
Validate that all roles have hosts
Commander needn't accumulate configuration
Pull latest image tag, so we can identity it
Default to deploying the config version
Remove unneeded Dockerfile.dind, update Readme
add D-in-D dockerfile, update Readme
`docker image ls` doesn't tell us what the latest deployed image is (e.g
if we've rolled back). Pull the latest image tag through to the server
so we can use it instead.
* main:
Add another assertion for `escape_shell_value`
Add tests for `Mrsk::Utils`
Fix indentation
Don't report exception here too
Don't report exception
Add CLI tests for remaining commands that are not tested yet
Minor: Properly require active_support
