Examples

Push a new image to a registry

First, you have to save the new image of the container and then commit it to a new image name.

$ docker container commit c423234f34fe34 arch-demo:latest

Then tag the image with hostname or IP address and port. After that push the image to the registry.

$ docker image tag arch-demo:latest registry:5000/admin/arch-demo:latest

$ docker image push registry:5000/admin/arch-demo:latest

Note: Here, registry is your registry host.

Push all tags of an image

$ docker image tag myImage registry:5000/myName/myImage:latest
$ docker image tag myImage registry:5000/myName/myImage:v1
$ docker image tag myImage registry:5000/myName/myImage:v1.0.1
$ docker image tag myImage registry:5000/myName/myImage:v1.0

Then push with —all-tags or -a flag. It will push all tags of the registry:5000/myName/myImage.

$ docker image push --all-tags registry:5000/myName/myImage
