kubectl describe pods xxx 提示错误Error syncing pod, skipping: failed to "StartContainer" for "POD" with ImagePullBackOff: "Back-off pulling image \"registry.access.redhat.com/rhel7/pod-infrastructure:latest\"" 看到registry.access.redhat.com/rhel7/pod-infrastructure:latest感觉很奇怪,我设置的仓库是grc.io,为什么去拉取这个镜像,怀疑是不是什么没有安装好。尝试运行docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest,提示redhat-ca.crt: no such file or directory。ls查看改文件是个软连接,链接目标是/etc/rhsm,查看没有rhsm,尝试安装yum install *rhsm*,出现相关软件,感觉比较符合,所以安装查看产生了/etc/rhsm文件夹。 再次运行kubectl get pods 如果依然报错,可参考下面的方案: wget http://mirror.centos.org/centos/7/os/x86_64/Packages/python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm rpm2cpio python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm | cpio -iv --to-stdout ./etc/rhsm/ca/redhat-uep.pem | tee /etc/rhsm/ca/redhat-uep.pem 这两个命令会生成/etc/rhsm/ca/redhat-uep.pem文件.
