# Add a source registry

A source registry is the connection to another registry that you want to copy images from, such as
Docker Hub or AWS ECR. Add it to your registry project first, then create a replication rule that
copies images from it into the project.

## Before you begin

You need:

- A registry project that reads **Created**, and, if you are a team member, a role with the create
  permission for Container Registry. See
  [Create a registry project](/myaccount/container-registry/how-to/create-a-registry-project/).
- The other registry's address, and the username and password of your account on it.

## Add the source registry

1. In MyAccount, under **Storage**, click **Container Registry**, and click your project. Open its
   **Source Registries** tab, headed **Manage Registries**.
2. Click **+** (**New Registry Endpoint**). **Create Registry Endpoint** opens.
3. In **Type**, choose the kind of registry you copy from: **Alibaba ACR**, **Artifact Hub**,
   **AWS ECR**, **Azure ACR**, **Docker Hub**, **Docker Registry**, **DTR**, **Github GHCR**,
   **Gitlab**, **Harbor**, **Huawei SWR**, **JFrog Artifactory**, or **Tencent TCR**.
4. In **Name**, enter a name for the connection. It starts with a lowercase letter, uses the same
   characters as a project name, and must be unused in this project.
5. (Optional) In **Description**, add a note about the source registry.
6. In **Endpoint URL**, enter the other registry's address. For some types, **Endpoint URL** is a
   list of the provider's endpoints: choose the one your images are in.
7. In **Access ID** and **Access Secret**, enter the username and password of your account on the
   other registry. For **Docker Hub**, that is your Docker Hub username and your password or a Docker
   Hub access token.
8. Keep **Verify Remote Cert** checked. Clear it only when the source registry uses a self-signed or
   untrusted certificate.
9. Click **Test Connection** to check the details without saving them. A working connection is
   confirmed; otherwise you see `Either Access Key, Access Secret, or Endpoint URL is Invalid.`
10. Click **Create**.

The source registry is listed on the **Source Registries** tab with its **Name**, **Type**, **URL**,
**Description**, and **Updated Time**. If the connection test fails, see
[Troubleshooting Container Registry](/myaccount/container-registry/troubleshooting/container-registry/#either-access-key-access-secret-or-endpoint-url-is-invalid).

## Edit a source registry

1. In MyAccount, under **Storage**, click **Container Registry**, click your project, and open its
   **Source Registries** tab. Open the source registry's **Actions** menu and click **Edit**.
   **Edit Registry Endpoint** opens.
2. Change the details you need. Enter the **Access Secret** again, even if it has not changed.
3. Click **Update**.

## Delete a source registry

Before you delete a source registry, delete the replication rules that use it; see
[Create a replication rule](/myaccount/container-registry/how-to/create-a-replication-rule/#delete-a-rule).

1. In MyAccount, under **Storage**, click **Container Registry**, click your project, and open its
   **Source Registries** tab. Open the source registry's **Actions** menu and click **Delete**.
2. **Confirm Delete Registry** asks **Are you sure you want to delete <name> Registry?** Confirm to
   delete it.

Your project can now copy images from the source registry. Next, create a rule that says what to
copy and when; see
[Create a replication rule](/myaccount/container-registry/how-to/create-a-replication-rule/).
