Launching backstopJS container as a "sibling" from within the service-cli container

[justinlevi]

We are looking to create a local development and CI workflow with visual regression testing using backstopjs.

We have a reasonable workflow established with backstopjs using the official docker container detailed in your blog post here:

This works great on mac but we're looking for a way to launch the backstopjs container as a "sibling" from within the bash cli. I found some documentation on how to do this, but I'm pretty new to docker and I'm feeling kinda lost...

I started playing around with this idea here by updating the docker-cli dockerfile here:
justinlevi/service-cli@51104c4#diff-f5069010bde43f486fa2ec4ffbfa9739

Any thoughts on whether or not this is a good idea and how I might get this to work?

I'm thinking this approach would also allow visual regression tests to run in a CI environment a little easier

@justinlevi dind (Docker in Docker) is, probably, not the best approach here.

I'd suggest creating a custom fin command (fin backstop), which would then run your backstop tests. Similar to how you can have fin behat to run Behat tests. This command can be used both locally and in CI.

Take a look at https://github.com/docksal/qa-suite. It has not been updated in a while, but it's a good start anyway.

Thanks for the response. I didn't know about the qa-suite repo. Definitely some ideas in there I think I can adopt for our setup.

One issue we're running into with this approach on Windows though is that Babun doesn't seem to work with docker commands well

babun/babun#655

There is another babun fork that seems to work, but haven't had a chance to try that yet.

To further complicate the situation I'm also looking to run backstopjs on several sites passing in the appropriate config file stored for each site. I'll post back if I can make some progress.

@justinlevi run fin docker <whatever you wanted>. It will run fine.

Any more questions left on this issue or can it be closed?
