This is the hangup for most CI/CD systems with containers. Typical configurations (e.g. Gitlab basic setup) don't leverage any caching, so every container is built 100% from scratch, every time.
Adjusting the system to properly utilize caching and ordering your container builds in a way that the most volatile steps are as late as possible in the build will massively speed up container builds.
