swarmd package
This adds a swarmd package for Moby which contains the standalone
swarmkit orchestration daemon (swarmd) and CLI tool (swarmctl).
The package tracks [docker/swarmkit#1965][PR1965] which is a WIP PR adding a containerd executor to swarmkit.
With a suitable moby image (such as swarmd.yml from this directory)
something like this should work:
runc exec swarmd swarmctl service create --image docker.io/library/nginx:alpine --name nginx
runc exec swarmd swarmctl service ls
TODO
Currently the swarm state directory needs to be at a path which is
identical from the PoV of both the containerd and swarmd
processes. For now this means that the swarmkit state is put in
/var/lib/containerd/swarmd.
Bootstrapping a cluster needs more invesigation. Tokens and join
addresses can currently only be passed on the swarmd command line
which is inconvenient for automated image deployment.
Swarmkit [PR 1965][PR1965] also contains a number of TODOs which are not separately listed here.
