@hsanjuan this should also fix the docker build (it was calling an non existent image).

[hsanjuan]

Small ask. Thanks for contributing this!

[Jorropo]

@hsanjuan done

[hsanjuan]

@Jorropo it seems docker is still borked

[Jorropo]

@hsanjuan it works now (on my machine at least) :)

Edit:
The go test isn't working anymore, absolutely no idea why, it was working at 0393c0c but isn't at dc7a3d8 but I havn't made any change to the go code.
See the old one : https://travis-ci.com/github/ipfs/ipfs-cluster/jobs/379201483

I'm gonna try a restart.

It finally builds !
