[REQ] Cache build steps if not modified

[keithmattix]

What kind of request is this?

None

What is your request or suggestion?

not sure if this is possible, but it would be great to be able to cache previous build steps (maybe as image layers or something) so that I can put expensive ones first (e.g. compiling protobuf). That way, if I don't change the build script, I don't have to run them again

Are you willing to submit PRs to contribute to this feature request?

• Yes, I am willing to implement it.

maybe as image layers or something)

This we cannot do.

What we can do is setup caching like ccache, go mod/build caches, etc.
