Docker Build Cache Reuse Docker utilizes a layering system for its images. Each command in a Dockerfile creates a new layer that is built upon the previous one. This layering system is leveraged by Docker’s build cache. If Docker recognizes that a layer hasn’t changed (i.e., the command is the same and the context hasn’t changed), it reuses the existing layer instead of rebuilding it. When building .NET applications in Docker, one common practice is to restore dependencies as a separate step before the application is built. This is done because restoring dependencies can be a time-consuming process, and it’s often the case that dependencies change less frequently than the application code. By restoring dependencies as a separate step, Docker can reuse the cached layer for the restore step, significantly speeding up the build process. ...
