### swarmd package
|
||||
|
||||
This adds a `swarmd` package for Moby which contains the standalone
|
||||
swarmkit orchestration daemon (`swarmd`) and CLI tool (`swarmctl`).
|
||||
|
||||
The package tracks [ijc's `container-wip` branch][containerd-wip].
|
||||
Compared with mainline swarmkit (which container a basic containerd
|
||||
executor merged in [PR1965]) this reworks the executor to use the
|
||||
container client library and adds support for CNI networking.
|
||||
|
||||
With a suitable LinuxKit image (such as `swarmd.yml` from this
|
||||
directory) something like this should work:
|
||||
|
||||
ctr exec -- swarmd swarmd swarmctl service create --image docker.io/library/nginx:alpine --name nginx
|
||||
ctr exec -- swarmd swarmd swarmctl service ls
|
||||
|
||||
Note that `swarmd` uses the "swarmd" containerd namespace, so to see
|
||||
swarmd managed containers you will need to use `-n swarmd` on all
|
||||
`ctr` commands e.g.:
|
||||
|
||||
ctr -n swarmd containers ls
|
||||
|
||||
Alternatively you may export `CONTAINERD_NAMESPACE=swarmd`.
|
||||
|
||||
### TODO
|
||||
|
||||
Bootstrapping a cluster needs more investigation. 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.
