Bug: Builds fail because cache size is getting too big

[yuvii]

📜 Description

We have a pipeline where builds continuously fail because the cache size is too big.

Looking over the build history we can see how in a period of one month it grew from around ~400Mb to a staggering size of almost 4Gb

It grows in size, until it's too big and the build fails, then we have to run the build manually without cache, so it shrinks again for a while before it grows once more. We have to repeatedly do this.

👟 Reproduction steps

I'm not sure. I don't know if this is a unique situation because our repository is large to begin with (monorepo), or something else.

👍 Expected behavior

Cache should be pretty consistently the same size.

👎 Actual Behavior

Cache grows in size seemingly to no end.

Are you using buildx? USE_BUILDX flag in devtron cm

As discussed over discord, using buildx eliminates this issue of increasing cache size. We recommend using the same
