  日志可能会显示镜像拉取源两次，如上例中所示。

  如果您的 ImageContentSourcePolicy 对象列出了多个镜像，OpenShift Container Platform 会尝试按照配置中列出的顺序拉取镜像，例如：

  Trying to access \"li0317gcp1.mirror-registry.qe.gcp.devcluster.openshift.com:5000/ocp/release@sha256:1926eae7cacb9c00f142ec98b00628970e974284b6ddaf9a6a086cb9af7a6c31\"
  Trying to access \"li0317gcp2.mirror-registry.qe.gcp.devcluster.openshift.com:5000/ocp/release@sha256:1926eae7cacb9c00f142ec98b00628970e974284b6ddaf9a6a086cb9af7a6c31\"
