To kick off the provider would be nice to have the big picture of out how Vagrant features / commands map to docker "stuff". These are thoughts about how the integration might look like under the hood:
- how can we tell docker to "just start" a container? "docker start base" would start the base image right?
- would probably need to commit the base "box" image and interact with that
- would it make sense to have a "commandless"
docker run -d <image>? - on "pure lxc" it basically means a "lxc-create" if the container has not been created yet and a "lxc-start -d"
- how can we get the container IP from the command line to SSH into it?
- I saw some github issue action a while ago that there was some thinking around something related to that (something like data volumes?)
- on "pure lxc" I just pass in '-s lxc.mount.entry=...' to
lxc-start
- does it map directly to docker images? what are the contents of an image?
- all boxes will need to have an ssh server running so that people can use provisioners and other plugins that depend on it. does the base image come with it? I can't remember now
- on "vanilla lxc" we have
- a metadata.json with optional template params for lxc-create (this file is required by vagrant and just needs to have a "provider" key, the rest is up to us)
- the rootfs tarball
- the lxc template script which gets symlinked to the right folder so that "lxc-create" finds it
- the current lxc template script is the same that comes with ubuntu 12.10 without the download / debootstrap part (i handle that when packaging the box)
- maps to "docker stop" + "docker wait"?
- maps to "docker rm" ?
- could use docker's built in port forwarding + a custom "vagrant port" command to lookup the public ports NATed
- it won't work for localhost redirects, we could use "redir" as it is currently implemented on vagrant-lxc already
Hey Fabio,
Thanks for putting this together! Would you mind making it a comment on the related issue (moby/moby#404)?
