Firebase service account for Docker

[brian-nguyen]

The production container should have a copy of the service account credentials in the final stage. Also investigate whether or not the vendor/ directory is being updated properly.

yeah you'll want to remove this and add vendor to your .dockerignore, my bad: 😋

RUN if [ ! -d "vendor" ]; then \
    go get -u github.com/golang/dep/cmd/dep; \
    dep ensure; \
    fi

Some history behind this decision - Docker caching for this layer seemed a bit finnicky, and since all Inertia builds are done either a) manually with dep ensure beforehand or b) automatically via Travis but with a fresh dep ensure, I added this condition so that if a vendor directory is mounted then Docker would 100% skip the potentially lengthy dep operations.

Didn't think too much of it when I added the configuration to Bumper, but in continuous deployment via Inertia, your vendor directory will never get updated if one exists already, since itll get mounted and the dep ensure step will be skipped 😢
