stack docker pull assumes /var/ruv/docker.sock exists

[Fuuzetsu]

If we start docker daemon with -H 172.17.42.1:5555, the /var/run/docker.sock file doesn't exist and stack docker pull fails:

[nix-shell:~/programming/HaskellR]$ stack docker pull
Pulling image from registry: 'tweag/haskellr:latest'
Post http:///var/run/docker.sock/v1.20/images/create?fromImage=tweag%2Fhaskellr%3Alatest: dial unix /var/run/docker.sock: no such file or directory.
* Are you trying to connect to a TLS-enabled daemon without TLS?
* Is your docker daemon up and running?
Could not pull Docker image:
    tweag/haskellr:latest
There may not be an image on the registry for your resolver's LTS version in
stack.yaml

In the meantime,

docker -H 172.17.42.1:5555 pull tweag/haskellr:latest works fine so maybe stack should allow us to pass in extra flags to stack docker pull.

Did you try setting the DOCKER_HOST environment variable?

[Fuuzetsu]

That works, thanks!

Perhaps this would be a good q&a to copy over to stack overflow for future
searches?

@borsboom While I have your attention, is there anywhere I can see the dockerfiles used for fpco images? I'm currently getting

[nix-shell:~/programming/HaskellR]$ stack --docker build
/bin/bash: /opt/host/bin/stack: No such file or directory

That image is based on FROM fpco/stack-build:lts-2.14 but I can't find the dockerfile for that to check what changed.

Sorry for piggybacking this issues, don't know where to ask otherwise, are you on IRC?

@snoyberg I'll do that now and post a link in few minutes.

@Fuuzetsu See #624

[nix-shell:~/programming/HaskellR]$ stack --docker build
/bin/bash: /opt/host/bin/stack: No such file or directory

Stack is supposed to mount itself in the container at that location, but it would appear that something is going wrong. Can you show --verbose output?

The haskell-stack mailing list is a good place. I'm not on IRC.

Let's continue in #974
