Cache location with gitlab-runner and docker executor on Windows?

Question

Where are the zips of the job caches when running gitlab-runner on Windows with docker executor ?

Answer 1

Here is what I found on the computer executing gitlab-runner, which has a more or less default configuration:

C:\ProgramData\docker\volumes\<runner-id>\_data\<path\to\repo>\<cache key>-N\cache.zip

With:

• <cache key> the value of the cache key provided from .gitlab-ci.yml.

• N an integer close to 1, possibly due to parallel builds (?). I think that sometimes the directory name is simply <cache key>.
