Initial login

  1. You will need to be logged in to the Orka CLI using the orka3 login command in your terminal, and connected to the VPN as outlined in your IP plan.
  2. Navigate to your Harbor URL included in your IP Plan in a web browser. This will typically be the last available IP in your Orka subnet. Example: https://10.221.189.254. Your Harbor metrics URL will differ, and have the /metrics destination. Example: <http://10.221.189.254:9090/metrics>. Each Harbor instance includes a Let’s Encrypt certificate, enabling you to access your instance via FQDN by adding the appropriate entry to your local hosts file.

Key Harbor web interface features

​
Project summary:

The project section provides an overview of:
  • The total number of repositories in your project
  • Your storage usage and quota limits
  • Recent activity and statistics
  • Project members and roles

​
Repository management:

The ‘repositories’ section provides a detailed overview of:
  • All the repositories within your project
  • Browsing image tags and versions
  • Delete images if necessary (see ‘Garbage collection’ section below)

​
User management:

As a Project Admin, you can:

​
Using Harbor with the Orka CLI:

Add credentials to Orka to access the Harbor OCI repository: orka3 regcred add -u <OCI.User> -p <OCI.Pass> <OCI.FQDN>

​
Pulling images:

Instruct all Orka nodes to fetch an image from the OCI repository: orka3 imagecache add <OCI.FQDN>/library/<Image.Name> --all Cache the image to a single node: orka3 imagecache add <OCI.FQDN>/library/<Image.Name> --nodes <Node.Name> Monitor the status of the image being fetched: orka3 imagecache info <OCI.FQDN>/library/<Image.Name> For more information, run orka3 regcred --help command in the Orka CLI.

​
Pushing images:

The state of a running VM is saved on the host and pushed to your Harbor container registry. This operation is applicable only to Apple silicon-based VMs. The provided image must be in the following format: server.com/repository/image:tag. If --namespace is not set, Harbor assumes that the VM is running in the orka-default namespace.
Registry credentials must exist in the same namespace as the VM. Registry credentials are required to authenticate to the registry for the push operation. For more information, run orka3 regcred --help in the Orka CLI. Pushing an OCI image is an async operation. To check the status of the operation, run:
orka3 vm get-push-status JOB_NAME

​
Usage:

orka3 vm push VM_NAME IMAGE[:TAG] [flags]

​
Image management and deletion:

​
Deleting images:

Note: Images must be deleted through Harbor, not via the Orka CLI.
  1. Log in to the Harbor web interface
  2. Navigate to your project
  3. Select the repository that contains the image for deletion
  4. Check the box next to the image tag(s) you want to delete
  5. Click ‘DELETE’ to confirm the action

​
Garbage collection:

  • Default schedule: Garbage collection runs hourly to reclaim storage space from deleted images
  • Timing: Garbage collection occurs hourly, at the top of the hour
  • Custom scheduling: If you would like to adjust your instance’s garbage collection schedule, please contact our support team.
Please note that deleted images are not immediately removed from storage. They are marked for deletion and then cleaned up during the next garbage collection cycle.

​
Storage quota and limits:

Your Harbor instance comes with pre-defined storage quotas. You can monitor your resource usage via the Harbor web interface under your project settings. If you attempt to push an image and have hit your storage quota, you will be met with an internal server error.

​
Example:

Image push progress: 8%
Error: internal error (13): Unexpected status code: 500
orka-engine image push 90gbventurassh.orkasi -u admin -p Harbor12345 0.26s user 0.04s system 0% cpu 51.752 total
If you encounter this error, we recommend logging into your Harbor instance using the instructions above, and verifying that you have not hit your storage quota. This can be viewed in the Harbor web interface, on the right side of the screen. HarborQuota.png If you have hit your quota and need to free up space on your instance urgently, or need to increase your storage limits for any reason, please contact our support team.
