4.7.2.4. 测试软件包清单格式目录镜像

流程

1. 拉取 Operator 目录镜像：

   $ podman pull <registry_host_name>:<port>/olm/redhat-operators:v1

2. 运行镜像：

   $ podman run -p 50051:50051 \
       -it <registry_host_name>:<port>/olm/redhat-operators:v1

3. 使用 grpcurl 查询正在运行的镜像中的可用软件包：

   $ grpcurl -plaintext localhost:50051 api.Registry/ListPackages

   输出示例

   {
     "name": "3scale-operator"
   }
   {
     "name": "amq-broker"
   }
   {
     "name": "amq-online"
   }

4. 在频道中获取最新的 Operator 捆绑包：

   $  grpcurl -plaintext -d '{"pkgName":"kiali-ossm","channelName":"stable"}' localhost:50051 api.Registry/GetBundleForChannel

   输出示例

   {
     "csvName": "kiali-operator.v1.0.7",
     "packageName": "kiali-ossm",
     "channelName": "stable",
   ...

5. 获取镜像摘要：

   $ podman inspect \
       --format='{{index .RepoDigests 0}}' \
       <registry_host_name>:<port>/olm/redhat-operators:v1

   输出示例

   example_registry:5000/olm/redhat-operators@sha256:f73d42950021f9240389f99ddc5b0c7f1b533c054ba344654ff1edaf6bf827e3

6. 假设命名空间 my-ns 中存在一个支持您的 Operator 及其依赖项的 Operator 组，使用镜像摘要创建一个 CatalogSource 对象。例如：

   apiVersion: operators.coreos.com/v1alpha1
   kind: CatalogSource
   metadata:
     name: custom-redhat-operators
     namespace: my-ns
   spec:
     sourceType: grpc
     image: example_registry:5000/olm/redhat-operators@sha256:f73d42950021f9240389f99ddc5b0c7f1b533c054ba344654ff1edaf6bf827e3
     displayName: Red Hat Operators

7. 创建一个可从您的目录镜像解析最新可用 servicemeshoperator 及其依赖项的订阅：

   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: servicemeshoperator
     namespace: my-ns
   spec:
     source: custom-redhat-operators
     sourceNamespace: my-ns
     name: servicemeshoperator
     channel: "1.0"
