• Registry Service: Developers can store and manage Docker and OCI images using Harbor. Harbor is an open-source container image registry that secures images with role-based access control.

Procedure

Login to Harbor Registry with the vSphere Docker Credential Helper.

docker-credential-vsphere login <container-registry-IP> --user [email protected]

Note:While providing --user username is acceptable for login, you should use the UserPrincipalName (UPN) syntax ( --user [email protected]) to login and use docker push commands.

Tag the image that you want to push to the project in Harbor Registry with same name as the

namespace, where you want to use it:

docker tag <image-name>[:TAG] <container-registry-IP>/<project-name>/<image-name>[:TAG]

For example:

docker tag hello-world:latest 10.179.145.77/tkgs-cluster-ns/hello-world:latest

docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

10.179.145.77/tkgs-cluster-ns/hello-world latest bf756fb1ae65 10 months ago

13.3kB

hello-world latest bf756fb1ae65 10 months ago 13.3kB

To push an image to a project in Harbor, run the following command:Syntax:

docker push <container-registry-IP>/<namespace-name>/<image_name>

For example:

docker push 10.179.145.77/tkgs-cluster-ns/hello-world:latest

Expected result.

The push refers to repository [10.179.145.77/tkgs-cluster-ns/hello-world]
