先决条件
- 从 Red Hat OpenShift Cluster Manager 获取了镜像 pull secret。
-
已安装 OpenShift CLI（
oc）。
流程
使用
oc adm命令提取与特定发行版本对应的driver-toolkit的镜像 URL：对于 x86 镜像，命令如下：
oc adm release info quay.io/openshift-release-dev/ocp-release:4.16.z-x86_64 --image-for=driver-toolkit
$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.16.z-x86_64 --image-for=driver-toolkitCopy to Clipboard Copied! Toggle word wrap Toggle overflow 对于 ARM 镜像，命令如下：
oc adm release info quay.io/openshift-release-dev/ocp-release:4.16.z-aarch64 --image-for=driver-toolkit
$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.16.z-aarch64 --image-for=driver-toolkitCopy to Clipboard Copied! Toggle word wrap Toggle overflow
输出示例
quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:b53883ca2bac5925857148c4a1abc300ced96c222498e3bc134fe7ce3a1dd404

podman pull --authfile=path/to/pullsecret.json quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:<SHA>
$ podman pull --authfile=path/to/pullsecret.json quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:<SHA>Copy to Clipboard Copied! Toggle word wrap Toggle overflow
