Wait, docker caches layers, you don't have to rebuild everything from scratch all the time... right? | ||

It does if you are building on the same host with preserved state and didn't clean it. There are lots of cases where people end up with with an empty docker repo at every CI run or regularly empty the repo because docker doesn't have any sort of intelligence space management (like LRU). | ||

To get fine-grained caching you need to use cache-mounts, not just cache layers. But the cache export doesn't include cache mounts, therefore the docker github action doesn't export cache mounts to the CI cache. | ||
