Kubernetes创建启动容器： -------------------------------------------------------------------- [docker@localhost ~]$ kubectl create -f kubernetes_yaml/ replicationcontroller "mysql" created service "mysql" created replicationcontroller "myweb" created service "myweb" created -------------------------------------------------------------------- 检查pod： -------------------------------------------------------------------- [docker@localhost ~]$ kubectl get pods NAME READY STATUS RESTARTS AGE mysql-7shv6 0/1 ContainerCreating 0 6s myweb-2vg5v 0/1 ContainerCreating 0 6s myweb-hz3zd 0/1 ContainerCreating 0 6s -------------------------------------------------------------------- 这是容器状态都属于ContainerCreating，而不是Running 解决方案： 方案一： -------------------------------------------------------------------- [root@localhost ~]# yum install *rhsm* -y [root@localhost ~]# docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest -------------------------------------------------------------------- 到这里如果检查pod状态还是ContainerCreating，尝试方案二 方案二： -------------------------------------------------------------------- [root@localhost ~]# docker pull docker.io/kubernetes/pause [root@localhost ~]# docker tag docker.io/kubernetes/pause gcr.io/google_containers/pause-amd64:3.0 [root@k8s ~]# docker rmi -f docker.io/kubernetes/pause -------------------------------------------------------------------- 到这里先进行delete，在重新创建容器 -------------------------------------------------------------------- [docker@localhost ~]$ kubectl delete -f kubernetes_yaml/ replicationcontroller "mysql" deleted service "mysql" deleted replicationcontroller "myweb" deleted service "myweb" deleted -------------------------------------------------------------------- 新建完成后，进行检查pod状态，如果还是ContainerCreating状态，方案三一定可以解决 方案三： -------------------------------------------------------------------- [root@localhost ~]# wget http://mirror.centos.org/centos/7/os/x86_64/Packages/python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm [root@localhost ~]# 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 [root@localhost ~]# docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest -------------------------------------------------------------------- 到这里就算结束了，这三种方案一定会解决【open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory】证书的问题。
