Docker-compose does not use docker endpoint set via docker context

Docker Engine Compose
1

I am using docker-cli and docker-compose on my mac, installed via Docker for Mac.

I am not using the docker engine on the mac but I’ve used docker context to use some other host on my network.

For docker commands everything goes as expected, all commands invoked with the docker command are executed on the remote docker engine.

When I try to use docker-compose, it gives me an error:
ERROR: Couldn't connect to Docker daemon. You might need to start Docker for Mac.
This is as expected: I am not using that.

I did notice that if I prepend my docker-compose command with DOCKER_HOST=tcp://xxx:1234 it does work. I was using docker context to avoid setting this environment variable.

Is this a bug or a feature request or am I using it not correctly? I am not sure where to report so that is why I put the request here first. I would assume that docker-compose is able to use the same endpoint set via docker context.

Hey @joggienl, I ran into the same issue and am not sure if it’s a bug or just (still) not implemented. Did you get it to work or find more info on the issue somewhere?

I have not tried in a while to be honest.
Currently I am using a workflow with docker-machine and docker-compose which works so far so good.
