Support for local dev with Docker/docker-compose

[adelevie]

Love the project. I'd like to be able to contribute without worrying about dependencies or setting of a golang environment on my host. Is this feasible? Happy to take a stab it if this is something you're interested in.

Hi @adelevie , you should be able to do this already with make run-docker.

[adelevie]

Huh. I tried that and got this error:

Makefile:13: recipe for target 'build-docker' failed
make: *** [build-docker] Error 1

Is golang somehow a host dependency?

[treeder]

oh, need to run glide install -v, give me a minute, I have a docker image for glide we can do that with to make it so you don't need go at all.

[adelevie]

That'd be fantastic!

[treeder]

Pull request here: #545

[adelevie]

Taking a look.

[treeder]

Try make docker-dep in that branch.

[adelevie]

Just got

➜  functions git:(make-update) make docker-dep
make: *** No rule to make target 'docker-dep'.  Stop.

[treeder]

Oops, try that again.

[adelevie]

make docker-dep and make docker-build seemed to work fine. make test-docker and make run-docker didn't though.

➜  functions git:(make-update) make test-docker

➜  functions git:(make-update) make docker-run

[treeder]

I changed them all to docker-, so now it's docker-dep, docker-build, docker-run and docker-test.

[adelevie]

Sweet, trying those now.

[treeder]

Did it work ok?

[adelevie]

hey @treeder, sorry.

works:

• make docker-dep
• make docker-build

doesn't work:

• make docker-run
• make docker-test

To get make docker-run working, rewrite line 27 to docker-run: docker-build. I still can't get make docker-test working though.
