Tag Docker image for each BackstopJS release

[fusionfox]

It would be great if we could lock down our dependancy to a particular release of BackstopJS using the docker container, but the only tag on there at the moment is 'latest'

What do you recommend? Let’s do it. Also, that container is new, I don’t remember what version of chrome it’s using — but we should set it to >=v62 to be compatible with the flags we’re using.

FWIW: I don’t have much experience with containers— Would be super helpful if someone wants to take the lead to manage this.

I think the Docker container should have the same semver as the version of BackstopJS it's using, then we can lock down that dependancy.

Do you ever rebuild the container for the same version of Backstop?

Sounds like a sensible idea.

I'm sorry but I am not sure I understand the question -- but I'll try to explain. The container rebuild is triggered on every github push -- regardless of package version. I only bump the package version value before releasing a new NPM build. Hope that helps.
