Docker for Mac about docker-it-scala

[dlouwers]

Looks like the Spotify Docker API has OSX socket support covered. Maybe switch to that lib?

Thanks @dlouwers

I put config variables into README section. Works for me that way as well

[Ciaran0]

Cant get this working even with this work around
Is there anything else I could try?

I have exported the envirnment variables but when I do
docker-machine env
These do not seem to have been set. I am using the ZSH shell, could this be an issue?
docker-machine env export DOCKER_TLS_VERIFY="1" export DOCKER_HOST="tcp://192.168.99.100:2376" export DOCKER_CERT_PATH="/Users/ciaran/.docker/machine/machines/default" export DOCKER_MACHINE_NAME="default"

@Ciaran0 Using docker-machine implies that you are not using the native OSX docker beta.

Unfortunately this http interface has been removed in the latest version. I am now trying to make it work using socat:

socat TCP-LISTEN:2375,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock &
export DOCKER_HOST=tcp://localhost:2375
unset DOCKER_TLS_VERIFY

Will have to combine this with the Netty DockerCmdExecFactory in order to get this workaround to work apparently. Ultimately there should be better Java socket file support on OSX though. Other languages like Go or Python are not having issues at all.

[viktortnk]

Ideally, we'd like to make implementation configurable if we go that way. I'm not vary familiar with spotify client and don't know it's strengths/weaknesses.

Unfortunately it is quite unlikely that I can look into it this week. Personally rolling back my machine to boot2docker temporarily :(

[dlouwers]

Can now confirm a workaround:

socat TCP-LISTEN:2375,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock &
export DOCKER_HOST=tcp://localhost:2375
unset DOCKER_TLS_VERIFY

And then use this alternative Docker implementation:

class Docker(override val config: DockerClientConfig) extends com.whisk.docker.Docker(config) {
      override val client = DockerClientBuilder.getInstance(config).withDockerCmdExecFactory(new com.github.dockerjava.netty.DockerCmdExecFactoryImpl).build()
      override val host = config.getDockerHost.getHost
    }

Can confirm that this works, though it can hardly be called secure running over plain http.

I think this can be closed, the README shows how to use this lib using the Spotify docker client which works both on mac / linux (win?)

override implicit val dockerFactory: DockerFactory = new SpotifyDockerFactory(DefaultDockerClient.fromEnv().build())

[viktortnk]

Yep, agree. Closing
