Configuring private image replication - Amazon ECR

Configuring private image replication

Replication settings are configured separately for each Region. Use the following steps to configure replication for your private registry.

To configure registry replication settings (AWS Management Console)

  1. Open the Amazon ECR console at https://console.aws.amazon.com/ecr/repositories.

  2. From the navigation bar, choose the Region to configure your registry replication settings for.

  3. In the navigation pane, choose Registries.

  4. On the Registries page, select your Private registry and choose Edit.

  5. On the Edit registry page, do the following.

    1. For Cross-Region replication, choose the cross-Region replication setting for the registry. If set to Enabled, choose one or more Destination regions.

    2. For Cross-account replication, choose the cross-account replication setting for the registry. If set to Enabled, enter the account ID for the destination account and one or more Destination regions to replicate to.

      Important

      For cross-account replication to occur, the destination account must configure a registry permissions policy to allow replication to occur. For more information, see Private registry permissions.

  6. Choose Save.

To configure registry replication settings (AWS CLI)

  1. Create a JSON file containing the replication configuration settings to define for your registry. This might contain one or more rules, with each rule containing a destination Region and account. If you want to replicate the images in your own registry between Regions, then specify your own account ID. For more examples, see Private image replication examples.

    { "rules": [ { "destinations": [ { "region": "destination_region", "registryId": "destination_accountId" } ] } ] }
  2. Create a replication configuration for your registry.

    aws ecr put-replication-configuration \ --replication-configuration file://crr-setup.json \ --region us-west-2
  3. Confirm your registry settings.

    aws ecr describe-registry \ --region us-west-2
