The run-only means run only without build.
yes
Why need export DOCKER_SKIP_REBUILD?
because sometimes the images may be not exist, so need to check whether have images before run container. refer: [PATCH v3 compass-ci 3/5] sparrow/4-docker/buildall: export env DOCKER_SKIP_REBUILD if env DOCKER_SKIP_REBUILD exists, then check image exists in $container/build script by call docker_skip_rebuild(), then not rebuild container. Thanks, Yinsi
Thanks, Xueliang
export env DOCKER_SKIP_REBUILD, then image already is exist, just exit build script, not rebuild container.
