A few days ago to do a docker run runner, now want to seem a bit out of the way. The real thing is to pack a Docker image, test it in the mirror, pass the test through to the mirror repository, post it to the test cluster for integration testing, and finally publish it to the production environment.
You are now done testing by packaging the test image and then generating the production image. In order to reduce the size of the production image (Golang image will be nearly 700m,golang:alpine mirror 250M, and Mutil+stage way to package to Alpine base package, only about 10M . Here is a detailed example of a file.
In a project, there is generally only one dockerfile, can not meet the requirements, found that the use of-f dockefile to specify a different file for packaging, but dockerfile.test this with the suffix method is problematic, should be used dockerfiletest this way. See Docker Build

One, package Docker image

First install Docker CE, refer to Docker installation
The Gitlab-runner user is then given Docker execution permissions, or the package will prompt for no permissions.

sudo usermod -aG docker gitlab-runnersudo -u gitlab-runner -H docker info

Very troublesome, how to test first, test pass and then package?
Does the test use a Docker runner to do the test and then use the Shell runner to package the upload release?
