perf: use COPY --link to increase Docker cache hit frequency (#1073) The --link flag is a feature of Docker BuildKit which tells Docker to treat the COPY'd layer independently of previous layers, enabling more aggressive build caching. For more details, see this Docker blog post [1]. When using COPY --link to copy files from a stage that does not contain /etc/passwd, we must --chown with $APP_USER_ID rather than app. Otherwise, the build would fail with "unknown user id".
