6.3.4. 提取 OpenShift Container Platform 安装程序

流程

1. 设置环境变量：

   $ export cmd=openshift-baremetal-install
   $ export pullsecret_file=~/pull-secret.txt
   $ export extract_dir=$(pwd)

2. 获取 oc 二进制文件：

   $ curl -s https://mirror.openshift.com/pub/openshift-v4/clients/ocp/$VERSION/openshift-client-linux.tar.gz | tar zxvf - oc

3. 展开安装程序：

   $ sudo cp oc /usr/local/bin
   $ oc adm release extract --registry-config "${pullsecret_file}" --command=$cmd --to "${extract_dir}" ${RELEASE_IMAGE}
   $ sudo cp openshift-baremetal-install /usr/local/bin
