Can not compile plugin with docker 1.10+ - missing Capabilities Volume API method

[jianghaitao]

I would like to test out the plugin but it failed to compile as one can see below. Would appreciate any help. Thanks.

Have not seen this error before - but FYI golang 1.6 is not generally supported due to stricter http HOST header checks. Really depends on your docker version and whether docker daemon sending correct HOST header yet.

Also looks like you are using a much newer version of the volume helpers, which has some new Capabilities method on the volume.Driver interface, which we do not yet support.

I've the same error with go 1.6 on ubuntu 14.04

We don't (yet) support docker 1.10 nor the new volume-driver plugin "Capabilities" method. Workaround until we add something proper is to downgrade the docker client libraries and docker volume helpers to < docker volume api 1.10.

[porcupie]

Looks like the Capabilities method was added in docker 1.12.

According to the documentation in the pull request for Capabilities method, we should return the following to indicate that Ceph RBD volumes managed by this plugin are global to the cluster:

{
  "Capabilities": {
    "Scope": "global"
  }
}

Fixed already
