5.2. 使用 Operator 在部分断开连接的 OpenShift Container Platform 环境中使用 Orchestrator 安装 Red Hat Developer Hub

流程

1. 为 oc-mirror 创建 ImageSetConfiguration 文件。您必须在 ImageSetConfiguration 文件中包括 Serverless Logic Operator 所需的镜像和 Operator，因为 oc-mirror 不会自动镜像所有镜像。使用以下示例：

   apiVersion: mirror.openshift.io/v2alpha1
   kind: ImageSetConfiguration
   mirror:
     additionalimages:
     - name: registry.redhat.io/openshift-serverless-1/logic-jobs-service-postgresql-rhel8:1.36.0
     - name: registry.redhat.io/openshift-serverless-1/logic-jobs-service-ephemeral-rhel8:1.36.0
     - name: registry.redhat.io/openshift-serverless-1/logic-data-index-postgresql-rhel8:1.36.0
     - name: registry.redhat.io/openshift-serverless-1/logic-data-index-ephemeral-rhel8:1.36.0
     - name: registry.redhat.io/openshift-serverless-1/logic-db-migrator-tool-rhel8:1.36.0
     - name: registry.redhat.io/openshift-serverless-1/logic-swf-builder-rhel8:1.36.0
     - name: registry.redhat.io/openshift-serverless-1/logic-swf-devmode-rhel8:1.36.0
     operators:
       - catalog: registry.redhat.io/redhat/redhat-operator-index:4.19
         # For example: registry.redhat.io/redhat/redhat-operator-index:v4.19
         packages:
         - name: logic-operator-rhel8
           channels:
           - name: alpha
             minVersion: 1.36.0
             maxVersion: 1.36.0
         - name: serverless-operator
           channels:
           - name: stable
             minVersion: 1.36.0
             maxVersion: 1.36.1

   另外，您可以使用 podman 命令查找缺少的镜像，并在版本更改时将它们添加到 additionalimages 列表中：

   IMG=registry.redhat.io/openshift-serverless-1/logic-operator-bundle:1.36.0-8
   mkdir local-manifests-osl
   podman create --name temp-container "$IMG" -c "cat /manifests/logic-operator-rhel8.clusterserviceversion.yaml"
   podman cp temp-container:/manifests ./local-manifests-osl
   podman rm temp-container
   yq -r '.data."controllers_cfg.yaml" | from_yaml | .. | select(tag == "!!str") | select(test("^.\\/.:.*$"))' ./local-manifests-osl/manifests/logic-operator-rhel8-controllers-config_v1_configmap.yaml

2. 通过运行 oc-mirror 命令，对 ImageSetConfiguration.yaml 文件中的镜像进行镜像(mirror)。例如：

   oc-mirror --config=imagesetconfiguration.yaml docker://<registry URL:port> --workspace file://<workspace folder> --authfile /path/to/authfile  --v2
   cd <workspace folder>/working-dir/cluster-resources/
   oc apply -f .

3. 使用以下任一方法下载编配器 1.8.2 的节点软件包管理器(NPM)软件包：

   • 从以下 registry 中下载为 tgz 文件：

     • https://npm.registry.redhat.com/@redhat/backstage-plugin-orchestrator/-/backstage-plugin-orchestrator-1.8.2.tgz
     • https://npm.registry.redhat.com/@redhat/backstage-plugin-orchestrator-backend-dynamic/-/backstage-plugin-orchestrator-backend-dynamic-1.8.2.tgz
     • https://npm.registry.redhat.com/@redhat/backstage-plugin-scaffolder-backend-module-orchestrator-dynamic/-/backstage-plugin-scaffolder-backend-module-orchestrator-dynamic-1.8.2.tgz
     • https://npm.registry.redhat.com/@redhat/backstage-plugin-orchestrator-form-widgets/-/backstage-plugin-orchestrator-form-widgets-1.8.2.tgz

   • 或者，使用来自 Red Hat NPM registry 的 NPM 软件包，如下例所示：

     npm pack "@redhat/backstage-plugin-orchestrator@1.8.2" --registry=https://npm.registry.redhat.com
     npm pack "@redhat/backstage-plugin-orchestrator-backend-dynamic@1.8.2" --registry=https://npm.registry.redhat.com
     npm pack "@redhat/backstage-plugin-scaffolder-backend-module-orchestrator-dynamic@1.8.2 --registry=https://npm.registry.redhat.com
     npm pack "@redhat/backstage-plugin-orchestrator-form-widgets@1.8.2" --registry=https://npm.registry.redhat.com

4. 将您下载的 NPM 软件包推送到 NPM 服务器，如下例所示：

   npm publish backstage-plugin-orchestrator-1.8.2.tgz
   npm publish backstage-plugin-orchestrator-backend-dynamic-1.8.2.tgz
   npm publish backstage-plugin-orchestrator-form-widgets-1.8.2.tgz
   npm publish backstage-plugin-scaffolder-backend-module-orchestrator-dynamic-1.8.2.tgz

5. 使用 OperatorHub 安装 OpenShift Serverless Operator 和 OpenShift Serverless Logic Operator。
6. 创建 Backstage 自定义资源(CR)。

7. 为 Orchestrator 配置 Backstage CR，如安装 Operator 的 Orchestrator 插件依赖项 中所述。

   创建所有资源并相应地配置 Backstage 实例。有关如何将 RHDH 指向 自定义 NPM registry 的说明，请参阅配置自定义 NPM registry。
