Dep: Wrong docker client version is discovered

[Trane9991]

What version of dep are you using (dep version)?

v0.3.1-151-g1d73a4a2

What dep command did you run?

dep ensure

What did you expect to see?

  name = "github.com/docker/docker"
  ...
  version = "v17.05.0-ce"

What did you see instead?

  name = "github.com/docker/docker"
  ...
  version = "v1.13.1"

Hey, I'm using github.com/fsouza/go-dockerclient/ so I have
github.com/docker/docker as the transitive dependency.
I suspect that dep takes v1.13.1 as latest version because of ce in the v17.05.0-ce version.

I tried to constrain the version or branch by adding
required = ["github.com/docker/docker"]

and

[[constraint]]
  branch = "master"
  name = "github.com/docker/docker"

But it gave me constraint errors during ensuring process.

I suspect it is because github.com/fsouza/go-dockerclient uses like 20 subpackages from docker, but I'm constraining the whole repo.

Do I need to write a constraint for each subpackage or how to overcome this issue?

@Trane9991 hi, since docker/docker is a transitive dependency, you have to use override. We have a FAQ entry for the same how-do-i-constrain-a-transitive-dependencys-version.

Also, I gave it a try to verify that it works as expected.

Add

[[override]]
  name = "github.com/docker/docker"
  version = "v17.05.0-ce"

to your Gopkg.toml and run dep ensure. You would see v17.05.0-ce added to Gopkg.lock.

branch = "master" works as well. Refers the latest commit revision.

Hope this helps 🙂

I love how Docker's silly versioning choices are haunting me across multiple repos. I had the same problem with the Docker Version Manager too! 🤦‍♀️

Sorry about the issue spam. I went off down the wrong track and nothing I said was right! 😊

go-dockerclient now supports dep.
