rostainer-deploy

A rostainer plugin that pushes package updates (from rostainer-package) to robots over ssh. Images go through a registry on your machine, so each robot downloads only the layers it doesn't have yet - after a code change, typically just the workspace's build. No image tar is copied, and robots need only ssh, Docker and Python 3.

pipx inject rostainer rostainer-deploy     # or: pip install 'rostainer[deploy]'
rostainer init --with deploy               # adds [plugins.deploy] to .rostainer.toml

[plugins.deploy]
[plugins.deploy.groups]
robots = ["robot1", "robot2"]

[plugins.deploy.targets.robot1]
host = "10.0.0.5"          # or a ~/.ssh/config alias
user = "ros"

[plugins.deploy.targets.robot2]
host = "robot2"

rostainer deploy setup                     # first time: copy your ssh key, check the robots, push
rostainer package create                   # build a new version
rostainer deploy push                      # send it to every robot (or: push robots, push robot1)
rostainer deploy status                    # what each robot runs
rostainer deploy rollback robot1           # back to the version it ran before
