请到「今天看啥」查看全文

restart docker to take effec t: sudo systemctl restart docker
[root@localhost ~]# systemctl restart docker

2.下载镜像,自己通过Dockerfile到dockerhub生成对镜像,也可以克隆我的

images=(kube-controller-manager-amd64 etcd-amd64 k8s-dns-sidecar-amd64 kube-proxy-amd64 kube-apiserver-amd64 kube-scheduler-amd64 pause-amd64 k8s-dns-dnsmasq-nanny-amd64 k8s-dns-kube-dns-amd64)
for imageName in ${images[@]} ; do
docker pull champly/$imageName
docker tag champly/$imageName gcr.io/google_containers/$imageName
docker rmi champly/$imageName
done

3.修改版本

docker tag gcr.io/google_containers/etcd-amd64 gcr.io/google_containers/etcd-amd64:3.0.17 && \
docker rmi gcr.io/google_containers/etcd-amd64 && \
docker tag gcr.io/google_containers/k8s-dns-dnsmasq-nanny-amd64 gcr.io/google_containers/k8s-dns-dnsmasq-nanny-amd64:1.14.5 && \
docker rmi gcr.io/google_containers/k8s-dns-dnsmasq-nanny-amd64 && \
docker tag gcr.io/google_containers/k8s-dns-kube-dns-amd64 gcr.io/google_containers/k8s-dns-kube-dns-amd64:1.14.5 && \
docker rmi gcr.io/google_containers/k8s-dns-kube-dns-amd64 && \
docker tag gcr.io/google_containers/k8s-dns-sidecar-amd64 gcr.io/google_containers/k8s-dns-sidecar-amd64:1.14.2 && \
docker rmi gcr.io/google_containers/k8s-dns-sidecar-amd64 && \
docker tag gcr.io/google_containers/kube-apiserver-amd64 gcr.io/google_containers/kube-apiserver-amd64:v1.7.5 && \
docker rmi gcr.io/google_containers/kube-apiserver-amd64 && \
docker tag gcr.io/google_containers/kube-controller-manager-amd64 gcr.io/google_containers/kube-controller-manager-amd64:v1.7.5 && \
docker rmi gcr.io/google_containers/kube-controller-manager-amd64 && \
docker tag gcr.io/google_containers/kube-proxy-amd64 gcr.io/google_containers/kube-proxy-amd64:v1.6.0 && \
docker rmi gcr.io/google_containers/kube-proxy-amd64 && \
docker tag gcr.io/google_containers/kube-scheduler-amd64 gcr.io/google_containers/kube-scheduler-amd64:v1.7.5 && \
docker rmi gcr.io/google_containers/kube-scheduler-amd64 && \
docker tag gcr.io/google_containers/pause-amd64 gcr.io/google_containers/pause-amd64:3.0 && \
docker rmi gcr.io/google_containers/pause-amd64

4.添加阿里源

[root@localhost ~]#  cat >> /etc/yum.repos.d/kubernetes.repo << EOF
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=0
EOF

5.查看kubectl kubelet kubeadm kubernetes-cni列表

[root@localhost ~]# yum list kubectl kubelet kubeadm kubernetes-cni
