Push images to Harbor

To be able to push images to Harbor, you'll need a robot account with push permissions. Teams are offered the option to download the Docker config for their team's private registry in Harbor.

1. Log in to the App Platform Console and select Download DOCKERCFG in the left menu. This downloads the docker config file to your local machine.

2. When you have downloaded the docker config, copy the file to your .Docker folder.

   Bash

   cp docker-team-labs.json $HOME/.Docker
   

3. Log in to the Harbor registry through the Docker CLI.

   Bash

   docker login harbor.<domain-of-your-cluster>
   

4. Build and tag your image.

   Bash

   docker build -t harbor.<your-domain>/team-<team-name>/<image-name>:<tag> <path to your Dockerfile>
   

5. Push the image to Harbor:

   Bash

   docker push harbor.<your-domain>/team-<team-name>/<image-name>:<tag>
