在Master节点上需要安装的服务：
[ docker | etcd | flannel | kube-apiserver | kube-scheduler | kube-controller-manager ]
在Slave（Node）节点上需要安装的服务：
[ docker | flannel | kubelet | kube-proxy ]
1.解决kubectl get pods时 No resources found的问题：
1、vi /etc/kubernetes/apiserver 2、找到 "KUBE_ADMISSION_CONTROL="--admission_control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota"，去掉ServiceAccount，保存退出。 3、systemctl restart kube-apiserver
2.解决在pul镜像image的时候没有凭据，没有redhat-ca.crt文件的问题：
[具体报错：Trying to pull repository registry.access.redhat.com/rhel7/pod-infrastructure ... open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory]
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 //前两个命令会生成/etc/rhsm/ca/redhat-uep.pem文件. docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest
