https://github.com/cmctec/ci-workflows/blob/main/.github/workflows/docker.yaml https://github.com/cmctec/ci-workflows/blob/main/.github/wor... This is my shared workflow which I apply to few dozens of projects in my company. Works like a charm! Extremely simple and understandable script. Build times are mere seconds (when cache works). I tried to understand this whole github actions stuff but decided that I don't need all that complexity.
