这篇文章主要讲解了“Kubernetes 1.17.0 有什么变化”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着丸趣 TV 小编的思路慢慢深入，一起来研究和学习“Kubernetes 1.17.0 有什么变化”吧！
Kubernetes 1.17.0 已发布，与之前版本的变化较大。
各服务的容器镜像版本如下：
k8s.gcr.io/kube-apiserver:v1.17.0
k8s.gcr.io/kube-controller-manager:v1.17.0
k8s.gcr.io/kube-scheduler:v1.17.0
k8s.gcr.io/kube-proxy:v1.17.0
k8s.gcr.io/pause:3.1
k8s.gcr.io/etcd:3.4.3-0
k8s.gcr.io/coredns:1.6.5拉取容器镜像：
原始的 kubernetes 镜像文件在 gcr 上，不能直接下载。我给镜像到了阿里云的杭州机房的容器仓库里，拉取还是比较快的。

Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run kubectl apply -f [podnetwork].yaml with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.199.173:6443 --token iq5i5d.xbrsj7ilq026786r \
--discovery-token-ca-cert-hash sha256:1275462841fd4d1a65734869bf75b73e80786cb7cd923937a6cdcec8f968c495
(base) supermap@openbox00:~/iobjectspy$关于 –control-plane-endpoint 的指定方法：
sudo kubeadm init --kubernetes-version=v1.17.0 \
--apiserver-advertise-address=192.168.199.173 \
--control-plane-endpoint=192.168.199.173:6443 \
--pod-network-cidr=10.244.0.0/16 \
--upload-certs使用 kubeadm 创建高可用集群，请参考：
Creating Highly Available clusters with kubeadm
注意，使用多个 Master 节点的 kubeadm init 方法后，输出有所不同：
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run kubectl apply -f [podnetwork].yaml with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
You can now join any number of the control-plane node running the following command on each as root:
kubeadm join 192.168.199.173:6443 --token rlxvkn.2ine1loolri50tzt \
--discovery-token-ca-cert-hash sha256:86e68de8febb844ab8f015f6af4526d78a980d9cdcf7863eebb05b17c24b9383 \
--control-plane --certificate-key 440a880086e7e9cbbcebbd7924e6a9562d77ee8de7e0ec63511436f2467f7dde
Please note that the certificate-key gives access to cluster sensitive data, keep it secret!
As a safeguard, uploaded-certs will be deleted in two hours; If necessary, you can use
kubeadm init phase upload-certs --upload-certs to reload certs afterward.
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.199.173:6443 --token rlxvkn.2ine1loolri50tzt \
--discovery-token-ca-cert-hash sha256:86e68de8febb844ab8f015f6af4526d78a980d9cdcf7863eebb05b17c24b9383感谢各位的阅读，以上就是“Kubernetes 1.17.0 有什么变化”的内容了，经过本文的学习后，相信大家对 Kubernetes 1.17.0 有什么变化这一问题有了更深刻的体会，具体使用情况还需要大家实践验证。这里是丸趣 TV，丸趣 TV 小编将为大家推送更多相关知识点的文章，欢迎关注！
