Force pull with docker_compose

[scalp42]

Describe the Feature You Want

We currently using latest tags on every image with docker-compose. We'd like to be able to "force pull" as even if we rebuild the image with Tilt using docker_build, docker-compose won't recreate the container / pull the latest changes for the latest tag.

Currently we're thinking of doing a random tag somehow and then override the tag:

my_service_docker_tag = local('printf $RANDOM')

docker_build("my_service:%s" % my_service_docker_tag)

# NOTE: to override by hand
override_image = { 'admin': {'image': "my_service:%s" % my_service_docker_tag } }
docker_compose(['./docker-compose.yml', encode_yaml({'services': override_image})])

The problem is that it doesn't work unless we save the actual docker-compose YAML file and then the containers get recreated.

Thanks in advance for the help or insights, feels like we're missing something.

The desired behavior you're describing is the way we hope/expect Tilt to behave currently, so I'd probably call this a bug.

I didn't have any luck reproing it on one of our sample projects though:

1. git clone https://github.com/tilt-dev/servantes && servantes
2. tilt up -f Tiltfile.dc vigoda
3. edit vigoda/main.go

Tilt rebuilds the vigoda_for_dc image and restarts the service.

(the docker-compose.yaml at HEAD just says "image: vigoda_for_dc", but it also works if I change it to "image: vigoda_for_dc:latest".

Any idea what I might be missing to repro the problem you're describing?
