4.5. 在多架构计算机器上的镜像流中导入清单列表

先决条件

• 已安装 OpenShift Container Platform CLI (oc)。

流程

• 以下示例命令演示了如何对 ImageStream cli-artifacts 进行补丁，以便 cli-artifacts:latest 镜像流标签作为清单列表导入。

  $ oc patch is/cli-artifacts -n openshift -p '{"spec":{"tags":[{"name":"latest","importPolicy":{"importMode":"PreserveOriginal"}}]}}'

验证

• 您可以通过检查镜像流标签来检查是否正确导入的清单列表。以下命令将列出特定标签的各个架构清单。

  $ oc get istag cli-artifacts:latest -n openshift -oyaml

  如果存在 dockerImageManifests 对象，则清单列表导入成功。
