    This specific version of ORAS is explicitly required for pushing packs to OCI registries.

Upload Pack to an ECR Registry

Follow the steps described below to set up your ECR registry, push the pack, and configure the registry in Palette.

  1. Open up a terminal session and export your AWS credentials as environment variables to authenticate with your AWS account.

    export AWS_ACCESS_KEY_ID=<your-access-key-id>
    export AWS_SECRET_ACCESS_KEY=<your-secret-access-key>
    export AWS_DEFAULT_REGION=<your-default-region>
  2. Additionally, export the required variables for creating the ECR repository and pushing the pack.

    • REPOSITORY_NAME - Specify a name for the repository that will store the pack files. For example, spectro-oci-registry.
    • NAME - The pack's name, which must match the name parameter in the pack.json file.
    • VERSION - The pack's version, which must match the version parameter in the pack.json file.
    • ACCOUNT_ID - Your AWS account ID, containing only numerical digits and no dashes.
    export REPOSITORY_NAME=<your-repository-name>
    export NAME=<your-pack-name>
    export VERSION=<your-pack-version>
    export ACCOUNT_ID=<your-aws-account-id>
  3. Issue the command below to create a base path repository to store your pack repositories.

    aws ecr create-repository --repository-name $REPOSITORY_NAME/spectro-packs/archive --region $AWS_DEFAULT_REGION
  4. Next, proceed to create the repository to store your pack.

    aws ecr create-repository --repository-name $REPOSITORY_NAME/spectro-packs/archive/$NAME --region $AWS_DEFAULT_REGION

Make sure to include the spectro-packs/archive path in all your repositories. Palette expects this namespace in custom OCI registries.

  1. After creating the ECR repositories, issue the command below to authenticate to your ECR registry. The aws ecr get-login-password generates an authorization token, which is then passed to the oras login command.

    aws ecr get-login-password --region $AWS_DEFAULT_REGION | oras login --username AWS --password-stdin $ACCOUNT_ID.dkr.ecr.$

    If the login is successful, you will receive a confirmation message.

    Login Succeeded
  2. Navigate to the directory containing the folder with the pack files.

  3. Before pushing the pack to the ECR registry, compress the contents of the pack folder into an archive file. Issue the command below to create the archive file. Replace <your_pack_folder_name> with the name of the folder containing the pack files.

    tar -czvf $NAME-$VERSION.tar.gz <your_pack_folder_name>
  4. Push the pack to the ECR registry.

    oras push $ACCOUNT_ID.dkr.ecr.$$REPOSITORY_NAME/spectro-packs/archive/$NAME:$VERSION $NAME-$VERSION.tar.gz

    The command output is similar to the following.

    Uploading ba65d21e72f1 your-pack-name-1.0.0.tar.gz
    Uploaded ba65d21e72f1 your-pack-name-1.0.0.tar.gz
    Pushed [registry]
    Digest: sha256:9067f964301c2b8e7a702fdbee35f5ca20a46695ef121e760e38967a2dd7cc4f
  5. After pushing the pack to the ECR registry, follow the steps in Add OCI Packs Registry to add your ECR registry to Palette.


    Palette automatically synchronizes the registries. However, you can manually trigger the synchronization if needed. From the OCI Registries page, click the three-dot Menu next to the registry name you added and select Sync.


Follow the steps below to validate that your pack has been successfully pushed to your OCI registry.

  1. Log in to Palette.

  2. From the left Main Menu, click on Profiles.

  3. Click Add Cluster Profile.

  4. Provide a name and select the type Add-on.

  5. In the following screen, click Add Pack.

  6. Select the ECR registry you added in the Registry drop-down Menu.

  7. Verify the pack you uploaded to the ECR registry is displayed.
