3. 输入以下命令来创建所需的服务密钥：

   sh-4.4$ python3 tools/generatekeypair.py quay-readonly

   Copy to Clipboard Toggle word wrap

   输出示例

   Writing public key to quay-readonly.jwk
   Writing key ID to quay-readonly.kid
   Writing private key to quay-readonly.pem

   Copy to Clipboard Toggle word wrap

步骤

1. 输入以下命令进入 Red Hat Quay 数据库环境：

   $ oc rsh example-registry-quay-app-76c8f55467-52wjz psql -U <database_username> -d <database_name>

   Copy to Clipboard Toggle word wrap

2. 输入以下命令显示 servicekeyapproval 的批准类型和相关备注：

   quay=# select * from servicekeyapproval;

   Copy to Clipboard Toggle word wrap

   输出示例

    id | approver_id |          approval_type           |       approved_date        | notes
   ----+-------------+----------------------------------+----------------------------+-------
     1 |             | ServiceKeyApprovalType.AUTOMATIC | 2024-05-07 03:47:48.181347 |
     2 |             | ServiceKeyApprovalType.AUTOMATIC | 2024-05-07 03:47:55.808087 |
     3 |             | ServiceKeyApprovalType.AUTOMATIC | 2024-05-07 03:49:04.27095  |
     4 |             | ServiceKeyApprovalType.AUTOMATIC | 2024-05-07 03:49:05.46235  |
     5 |           1 | ServiceKeyApprovalType.SUPERUSER | 2024-05-07 04:05:10.296796 |
   ...

3. 输入以下查询，将服务密钥添加到您的 Red Hat Quay 数据库中：

   quay=# INSERT INTO servicekey
     (name, service, metadata, kid, jwk, created_date, expiration_date)
     VALUES ('quay-readonly',
              'quay',
              '{}',
              '{<contents_of_.kid_file>}',
              '{<contents_of_.jwk_file>}',
              '{<created_date_of_read-only>}',
              '{<expiration_date_of_read-only>}');

   Copy to Clipboard Toggle word wrap

   输出示例

   INSERT 0 1

   Copy to Clipboard Toggle word wrap

4. 接下来，使用以下查询添加密钥批准：

   quay=# INSERT INTO servicekeyapproval ('approval_type', 'approved_date', 'notes')
     VALUES ("ServiceKeyApprovalType.SUPERUSER", "CURRENT_DATE",
              {include_notes_here_on_why_this_is_being_added});

   Copy to Clipboard Toggle word wrap

   输出示例

   INSERT 0 1

   Copy to Clipboard Toggle word wrap

5. 将创建的服务键行中的 approval_ id 字段设置为创建的服务密钥批准中的 id 字段。您可以使用以下 SELECT 语句来获取必要的 ID：

   UPDATE servicekey
   SET approval_id = (SELECT id FROM servicekeyapproval WHERE approval_type = 'ServiceKeyApprovalType.SUPERUSER')
   WHERE name = 'quay-readonly';

   UPDATE 1

步骤

1. 输入以下命令在 OpenShift Container Platform 部署中读取 Red Hat Quay 的 secret 名称：

   $ oc get deployment -o yaml <quay_main_app_deployment_name>

   Copy to Clipboard Toggle word wrap

2. 使用 base64 命令对 quay-readonly.kid 和 quay-readonly.pem 文件进行编码：

   $ base64 -w0 quay-readonly.kid

   Copy to Clipboard Toggle word wrap

   输出示例

   ZjUyNDFm...

   Copy to Clipboard Toggle word wrap

   $ base64 -w0 quay-readonly.pem

   Copy to Clipboard Toggle word wrap

   输出示例

   LS0tLS1CRUdJTiBSU0E...

   Copy to Clipboard Toggle word wrap

3. 输入以下命令来获取当前的配置捆绑包和 secret：

   $ oc get secret quay-config-secret-name -o json | jq '.data."config.yaml"' | cut -d '"' -f2 | base64 -d -w0 > config.yaml

   Copy to Clipboard Toggle word wrap

4. 编辑 config.yaml 文件并添加以下信息：

   # ...
   REGISTRY_STATE: readonly
   INSTANCE_SERVICE_KEY_KID_LOCATION: 'conf/stack/quay-readonly.kid'
   INSTANCE_SERVICE_KEY_LOCATION: 'conf/stack/quay-readonly.pem'
   # ...

   Copy to Clipboard Toggle word wrap

5. 运行以下命令保存文件和 base64 编码：

   $ base64 -w0 quay-config.yaml

   Copy to Clipboard Toggle word wrap

6. 将 Red Hat Quay Operator pod 缩减为 0。这样可确保 Operator 在编辑后不会协调 secret。

   $ oc scale --replicas=0 deployment quay-operator -n openshift-operators

   Copy to Clipboard Toggle word wrap

7. 编辑 secret 使其包含新内容：

   $ oc edit secret quay-config-secret-name -n quay-namespace

   Copy to Clipboard Toggle word wrap

   # ...
   data:
     "quay-readonly.kid": "ZjUyNDFm..."
     "quay-readonly.pem": "LS0tLS1CRUdJTiBSU0E..."
     "config.yaml": "QUNUSU9OX0xPR19..."
   # ...

   在只读模式下使用 Red Hat Quay on OpenShift Container Platform 部署，您可以安全地管理 registry 的操作并执行诸如备份和恢复的操作。
