Endpoints For Replications and Proxy Cache Projects

Endpoints are container image registries. They can be instances of the Container Registry platform, or other Harbor-based registries, or even non-Harbor-based ones.

Getting Your Access ID and Access Secret from Other Providers

When you create a new endpoint as described below, you will need to enter an Access ID and Access Secret. Different providers have different names for that.

Amazon ECR

In the case of AWS ECR, those are not your (root) user credentials but the so-called keys for programmatic access. Read this AWS documentation article to understand how you can access these keys in your AWS account.

Google Container Registry (GCR)

In GCR, those can be downloaded as a JSON file following the instructions from the official documentation.


Without Authorization

If your Quay registry does not require authorization, do not enter anything in the Access ID and Access Secret fields.

With Authorization

In this case, you need to leave the Access ID field empty and enter all credentials into the Access Secret field in JSON format, like this:

"oauth2_token": "YmQZ1QZENVmOD6v9kENzmfptNVhgBuy5oVl85eGV", 
"account_name": "account_name",
"docker_cli_password": "q6NVazikNqIf4coiQ+JvV4iqiCpkNjE0DLX8ZMQuFRbkHk5iMv6/hd4WdV3W3nyX"
  • The OAuth2 token can be skipped if you do not want to create a new organization;
  • Account name:
    • If you use robot account credentials, be aware that it can only be used in one Container registry system at the same time. Thus, you will need different robot accounts for every Container Registry instance;
    • Alternatively, and this is even recommended, use your personal account name;
  • Docker CLI password is your general CLI password.

Create New Endpoint

In the navigation pane:

  • Go to Administration;

  • Then to Registries;

  • Click + New Endpoint.

  • Fill in the form;

    • For the endpoint URL, use the URL of the registry;
    • If you want to connect to another Harbor-based registry, use the account name of your robot account as Access ID and its token as Access Secret;
    • Select if there is a security certificate on the other side or not.
  • Test the connection;

  • Save the endpoint if the test ran successfully.

Manage Existing Endpoints

You can either edit or delete any of the existing endpoints. In the Registries overview, select one endpoint for editing or one or multiple ones for deleting.
