I read the docs for installing custom software (https://circleci.com/docs/installing-custom-software/) and find I am not 100% clear on whether things I install with
apt-get would be cached. The docs say:
Naturally, downloading and compiling this custom software can take time, making your build longer. To reduce the time spent installing dependencies, CircleCI will cache them between builds.
I wasn’t clear if “will cache them between builds” literally meant it happens automatically and I don’t need to do anything further – that I’d only need to specify extra cache directories if I was compiling dependencies.
I tried searching through the forum for posts to clear this up. I found one or two from about a year ago that say the results of
apt-get installs are not cached and suggesting a few approaches to work around this. But I didn’t find anything more recent than this and it seems like it was a feature request at some point.
So my question is…what’s the current status?
