No url found for submodule path 'vendor/github.com/ogier/pflag' in .gitmodules

[TylerRick]

When I cloned the repo, I got this...

git clone git@github.com:micahhausler/container-tx.git
Cloning into 'container-tx'...

fatal: No url found for submodule path 'vendor/github.com/ogier/pflag' in .gitmodules

I don't see a .gitmodules so was surprised it even had any way to know that path was supposed to be a submodule.

But I learned from https://stackoverflow.com/a/4185579/47185 that git stores submodule directories with a special mode '160000'. Running git ls-files --stage | grep 160000 confirms that it is a submodule:

160000 45c278ab3607870051a2ea9040bb85fcb8557481 0	vendor/github.com/ogier/pflag
160000 ec7fdbb58eb3e300c8595ad5ac74a5aa50019cc7 0	vendor/github.com/sergi/go-diff
160000 e4d366fc3c7938e2958e662b4258c7a89e1f0e3e 0	vendor/gopkg.in/yaml.v2

I'm guessing you just forgot to add the .gitmodules file to git?

Anyway, the missing submodule leads to this error when I try to build (following the instructions from the Dockerfile):

Yea honestly I've been meaning to switch to dep, but this project hasn't had a whole lot of love in the last year.
