2.3. 在 Red Hat Developer Hub 中安装第三方插件

流程

1. 在 dynamic-plugins.yaml 文件中定义带有 oci:// 前缀的插件：

   oci://<image-name>:<tag>!<plugin-name>

   dynamic-plugins.yaml 文件中的配置示例

   plugins:
     - disabled: false
       package: oci://quay.io/example/image:v0.0.1!backstage-plugin-myplugin

   Copy to Clipboard

2. 通过将 REGISTRY_AUTH_FILE 环境变量设置为 registry 配置文件的路径，为私有 registry 配置身份验证。例如： ~/.config/containers/auth.json 或 ~/.docker/config.json。

3. 要执行完整性检查，请使用镜像摘要来代替 dynamic-plugins.yaml 文件中的标签，如下所示：

   dynamic-plugins.yaml 文件中的配置示例

   plugins:
     - disabled: false
       package: oci://quay.io/example/image@sha256:28036abec4dffc714394e4ee433f16a59493db8017795049c831be41c02eb5dc!backstage-plugin-myplugin

   Copy to Clipboard

4. 要应用更改，请重启 RHDH 应用程序。

流程

1. 使用以下示例在 dynamic-plugins.yaml 文件中指定归档 URL 及其完整性哈希：

   dynamic-plugins.yaml 文件中的配置示例

   plugins:
     - disabled: false
       package: https://example.com/backstage-plugin-myplugin-1.0.0.tgz
       integrity: sha512-9WlbgEdadJNeQxdn1973r5E4kNFvnT9GjLD627GWgrhCaxjCmxqdNW08cj+Bf47mwAtZMt1Ttyo+ZhDRDj9PoA==

   Copy to Clipboard

2. 要应用更改，请重启 RHDH 应用程序。

流程

1. 运行以下命令以从 NPM registry 获取完整性哈希：

   npm view --registry <registry-url> <npm package>@<version> dist.integrity

   Copy to Clipboard

2. 在 dynamic-plugins.yaml 文件中指定软件包名称、版本及其完整性哈希，如下所示：

   dynamic-plugins.yaml 文件中的配置示例

   plugins:
     - disabled: false
       package: @example/backstage-plugin-myplugin@1.0.0
       integrity: sha512-9WlbgEdadJNeQxdn1973r5E4kNFvnT9GjLD627GWgrhCaxjCmxqdNW08cj+Bf47mwAtZMt1Ttyo+ZhDRDj9PoA==

   Copy to Clipboard

3. 如果您使用自定义 NPM registry，请使用 registry URL 和身份验证详情创建一个 .npmrc 文件：

   .npmrc 文件示例

   registry=<registry-url>
   //<registry-url>:_authToken=<auth-token>

   Copy to Clipboard

4. 使用 OpenShift Container Platform 或 Kubernetes 时：

   • 使用 Helm Chart 通过创建 secret 添加 .npmrc 文件。例如：

     secret 配置示例

     apiVersion: v1
     kind: Secret
     metadata:
       name: <release_name>-dynamic-plugins-npmrc 

     1

     
     type: Opaque
     stringData:
       .npmrc: |
         registry=<registry-url>
         //<registry-url>:_authToken=<auth-token>

     Copy to Clipboard

     1

     将 <release_name > 替换为您的 Helm 发行版本名称。此名称是 Kubernetes 集群中每个 chart 安装的唯一标识符。

   • 对于 RHDH Helm Chart，使用以下格式命名 secret 进行自动挂载：

     <release_name>-dynamic-plugins-npmrc

5. 要应用更改，请重启 RHDH 应用程序。

1. 获取第三方插件源代码 ：克隆 plugins 存储库并导航到 Todo 插件 目录：

   获取第三方插件源代码

   $ git clone https://github.com/backstage/community-plugins
   $ cd community-plugins/workspaces/todo
   $ yarn install

   Copy to Clipboard

2. 导出后端和前端插件 ： 运行以下命令构建后端插件，调整动态加载的软件包依赖项，并生成自包含的配置模式：

   导出后端插件

   $ cd todo-backend
   $ npx @janus-idp/cli@latest package export-dynamic-plugin

   Copy to Clipboard

   导出后端插件命令的输出

   您可以运行以下命令来设置默认动态 UI 配置，创建前端插件资产，并为前端插件生成配置模式：

   导出前端插件

   $ cd ../todo
   $ npx @janus-idp/cli@latest package export-dynamic-plugin

   Copy to Clipboard

     "exposedModules": {
       "PluginRoot": "./src/index.ts"
     }
   }
   If you wish to change the defaults, add "scalprum" configuration to plugin "package.json" file, or use the '--scalprum-config' option to specify an external config.
