Published on Aug. 22, 2023, 12:19 p.m.
To push a Docker image to a registry, you first need to tag the Docker image with the registry URL, repository name, and appropriate tag using the docker tag
command. For example:
docker tag my_image registry.example.com/my_repository:my_tag
This command will tag the my_image
Docker image with the URL registry.example.com
, repository name my_repository
and tag my_tag
.
After tagging the image, use the docker push
command followed by the tagged image name to push the image to the registry. For example:
docker push registry.example.com/my_repository:my_tag
This command will push the my_image
Docker image to the registry with URL registry.example.com
, repository name my_repository
, and tag my_tag
.
Note that you need to be authenticated to the registry before you can push the image. For more information, refer to the Docker documentation on docker push
.
