I've made local changes to a docker image and used docker commit to place it in the cache and then docker image save to create a local copy, to ensure that it doesn't get lost by an accidental overwrite. However, I cannot find syntax for specifying, in a docker-compose.yaml file, that I want to use the local image. Is this possible?

CodePudding user response：

In the docker-compose you can specify the image name. You can create a tag and use that in your docker-compose.

I misunderstood the result of docker image save: it creates a tarball, not a full image. So it cannot be used directly - docker image load/docker import is needed to make it usable.

So this is not possible AFAICT. It seems unlikely that this feature is going to be developed later, either.
