I was reading the docs regarding docker buildx build to build to multiple architectures and I got puzzled with the --push option, it says that it pushes to the registry directly but how does it know or how can I specify where I want it to push the built images?

For more context, my plan is to push the images to my Gitlab private container registry from my Gitlab CI/CD pipeline

CodePudding user response：

First login to your private registry, with the command docker login myregistry.com. After that specify your registry in the tag name of your image docker buildx build --push -t myregistry/appname:version . and it should push your image after build.
