7.5.3. 使用 CLI 查看 Operator 目录源状态

您可以使用 CLI 查看 Operator 目录源的状态。

先决条件

  • 您可以使用具有 cluster-admin 角色的用户访问集群。
  • 已安装 OpenShift CLI(oc)。

流程

  1. 列出命名空间中的目录源。例如,您可以检查 openshift-marketplace 命名空间,该命名空间用于集群范围的目录源:

    $ oc get catalogsources -n openshift-marketplace

    输出示例

    NAME                  DISPLAY               TYPE   PUBLISHER   AGE
    certified-operators   Certified Operators   grpc   Red Hat     55m
    community-operators   Community Operators   grpc   Red Hat     55m
    example-catalog       Example Catalog       grpc   Example Org 2m25s
    redhat-marketplace    Red Hat Marketplace   grpc   Red Hat     55m
    redhat-operators      Red Hat Operators     grpc   Red Hat     55m

  2. 使用 oc describe 命令获取有关目录源的详情和状态:

    $ oc describe catalogsource example-catalog -n openshift-marketplace

    输出示例

    Name:         example-catalog
    Namespace:    openshift-marketplace
    ...
    Status:
      Connection State:
        Address:              example-catalog.openshift-marketplace.svc:50051
        Last Connect:         2021-09-09T17:07:35Z
        Last Observed State:  TRANSIENT_FAILURE
      Registry Service:
        Created At:         2021-09-09T17:05:45Z
        Port:               50051
        Protocol:           grpc
        Service Name:       example-catalog
        Service Namespace:  openshift-marketplace

    在上例的输出中,最后观察到的状态是 TRANSIENT_FAILURE。此状态表示目录源建立连接时出现问题。

  3. 列出创建目录源的命名空间中的 pod:

    $ oc get pods -n openshift-marketplace

    输出示例

    NAME                                    READY   STATUS             RESTARTS   AGE
    certified-operators-cv9nn               1/1     Running            0          36m
    community-operators-6v8lp               1/1     Running            0          36m
    marketplace-operator-86bfc75f9b-jkgbc   1/1     Running            0          42m
    example-catalog-bwt8z                   0/1     ImagePullBackOff   0          3m55s
    redhat-marketplace-57p8c                1/1     Running            0          36m
    redhat-operators-smxx8                  1/1     Running            0          36m

    在命名空间中创建目录源时,会在该命名空间中为目录源创建一个 pod。在前面的示例中,example-catalog-bwt8z pod 的状态是 ImagePullBackOff。此状态表示拉取目录源的索引镜像存在问题。

  4. 使用 oc describe 命令检查 pod 以获取更多详细信息:

    $ oc describe pod example-catalog-bwt8z -n openshift-marketplace

    输出示例

    Name:         example-catalog-bwt8z
    Namespace:    openshift-marketplace
    Priority:     0
    Node:         ci-ln-jyryyg2-f76d1-ggdbq-worker-b-vsxjd/10.0.128.2
    ...
    Events:

      Warning  Failed          8s (x3 over 47s)   kubelet            Error: ErrImagePull

    在前面的示例输出中,错误消息表示目录源的索引镜像因为授权问题而无法成功拉取。例如,索引镜像可能存储在需要登录凭证的 registry 中。
