This is based on https://github.com/docker/swarmkit/pull/1965 which adds a direct containerd executor to swarmkit. It is very much a work in progress. With a suitable moby image (such as projects/swarmd/swarmd.yml) 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 Signed-off-by: Ian Campbell <ian.campbell@docker.com>

### 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.
