18.4. 将引用附加到镜像标签

流程

1. 输入以下命令标记 OCI 介质工件：

   $ podman tag <myartifact_image> <quay-server.example.com>/<organization_name>/<repository>/<image_name>:<tag>

   Copy to Clipboard Toggle word wrap

2. 将工件推送到 Red Hat Quay registry。例如：

   $ podman push <myartifact_image> <quay-server.example.com>/<organization_name>/<repository>/<image_name>:<tag>

   Copy to Clipboard Toggle word wrap

3. 输入以下命令，使用带有 oras 的 OCI 1.1 引用 API 模式来附加清单：

   $ oras attach --artifact-type <MIME_type> --distribution-spec v1.1-referrers-api <myartifact_image> \
   <quay-server.example.com>/<organization_name>/<repository>/<image_name>:<tag> \
   <example_file>.txt

   Copy to Clipboard Toggle word wrap

   输出示例

   -spec v1.1-referrers-api quay.io/testorg3/myartifact-image:v1.0 hi.txt
   ✓ Exists    hi.txt                                                               3/3  B 100.00%     0s

7. 可选。您还可以使用 /v2/<organization_name>/<repository_name>/referrers/<sha256_digest& gt; 端点来发现引用器。要实现此目的，您必须在 config.yaml 文件中生成 v2 API 令牌并设置 FEATURE_REFERRERS_API: true。

   1. 更新 config.yaml 文件，使其包含 FEATURE_REFERRERS_API 字段。例如：

      # ...
      FEATURE_REFERRERS_API: true
      # ...

   3. 输入以下命令使用 base64 编码的令牌，并将 URL 端点改为 Red Hat Quay 服务器：

      $ curl --location '<quay-server.example.com>/v2/auth?service=<quay-server.example.com>&scope=repository:quay/listocireferrs:pull,push' --header 'Authorization: Basic <base64_username:password_encode_token>' -k | jq

      {
        "token": "<example_token_output>..."
      }
