Trouble vendoring docker with glide

[deinspanjer]

I'm working on a project and wanted to convert it over to using glide.

I ran glide create and generated the following yaml:

package: github.com/myco/myapp
import:
- package: github.com/dghubble/sling
- package: github.com/docker/docker
  subpackages:
  - api/types
  - api/types/container
  - api/types/strslice
  - client
- package: github.com/docker/go-connections
  subpackages:
  - nat
- package: github.com/kardianos/osext
- package: github.com/sanbornm/go-selfupdate
  subpackages:
  - selfupdate
- package: github.com/shibukawa/configdir
- package: golang.org/x/net
  subpackages:
  - context
- package: golang.org/x/oauth2

However, when I tried to run glide install, it kept failing with the errors:

[ERROR]	Error scanning github.com/docker/docker/api/types/container: open /Users/dre/.glide/cache/src/https-github.com-docker-docker/api/types/container: no such file or directory
...
[ERROR]	Error scanning github.com/docker/docker/api/types/strslice: open /Users/dre/.glide/cache/src/https-github.com-docker-docker/api/types/strslice: no such file or directory
...
[ERROR]	Error scanning github.com/docker/docker/client: open /Users/dre/.glide/cache/src/https-github.com-docker-docker/client: no such file or directory
[ERROR]	Failed to retrieve a list of dependencies: Error resolving imports

I tried various combinations of resetting my GOPATH and clearing my previous vendor directory.

Eventually I happened on the one thing that did work.

After creating the yaml, I had to manually run go get github.com/docker/go-connections. For some reason, that then let me run install without a problem, but if I try to run glide update, it still fails with the same errors.

This has something to do with the change Docker made between 1.12.3 and 1.13.0-dev. They removed the engine-api package and shuffled things around.

It looks like at some point, we put a dependency into our code based on the new 1.13.0-dev structure and I have to either refactor that back out or accept using the dev.

Is it possible to refer to 1.13.0-dev as a semantic version? Especially if I could accept a patch release to stable when it comes?

Docker uses trash for fixing their dependencies, so as a first step glide would need the changes from #740. Afterwards you could fix your dependencies e.g. like here https://github.com/stffabi/watchtower/blob/feature_DependencyFixed/glide.yaml#L6
