Question: purpose of ubuntu.tar.gz

[jdkent]

I am using the fmriprep .circleci/config.yml as a template for NiMARE (e.g. neurostuff/NiMARE#62) (this config has a lot of useful features! 💯 ), and I am curious what the purpose of the ubuntu.tar.gz is and whether it is necessary.

that tarball contains the docker layers of the ubuntu image.

I believe the idea was to reduce the odds of needing to pull down the Ubuntu image from docker hub, and thus the odds of rebuilding the entire image. There's a lot of debris in this file from trying to reuse layers from previous builds, because Circle does not play nicely with Docker except in the paid plans.

I see, thanks! I linked where the image gets loaded from the cache, but where/when did the image get first saved to cache? I couldn't see an obvious command that said to save ubuntu.tar.gz in cache.

Oh, looks like it's gone. We can probably remove that line, then.

[jdkent]

I can take care of that.

EDIT: on second thought, this may be a great first issue for anyone looking to contribute.
AFAIK that line is harmless, and it would allow a first time contributor to focus on git-flow.

Major 😻 to that, @jdkent ! I think all we need to do is add the right issue label(s).

Sorry for the educational value of that line, but I forgot of this discussion and removed it in 1bf4a21
