GitLab-CI how to increase cache lifetime?

Question

GitLab

For tests, I cached the python packages from requirements.txt, but the cache lifetime is short and after some time, the installation of packages starts again, how can I increase the cache lifetime?

Answer 1

In general, a cache does not have a parameter to its lifetime. Lives until the moment of its reset.
Is there a log with the reason for invalidating the cache? Maybe your cache is not synchronized between runners?
