为节点生成并配置密钥对

生成密钥对

[root@rancher-01 ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:sfL3YnyrNZsioS3ThuOTRME7AIyLxm4Yq396LAaeQOY root@rancher-01

Rancher关于Kubernetes 集群节点的角色定义

https://rancher.com/docs/rancher/v2.x/en/cluster-provisioning/production/nodes-and-roles/
https://kubernetes.io/docs/concepts/overview/components/

etcd

具有etcd角色的节点运行etcd,这是一个用于存储Kubernetes集群配置数据,具有一致性且高可用的键值存储服务。 etcd将数据复制到每个节点。
注意:在用户界面中,具有etcd角色的节点显示为“Unschedulable”,这意味着默认情况下不会将Pod调度到这些节点。

controlplane

具有controlplane角色的节点运行Kubernetes主组件(不包括etcd,因为它是单独的角色)。 有关组件包括kube-apiserver,kube-scheduler,kube-controller-manager和cloud-controller-manager。
注意:在用户界面中,具有controlplane角色的节点显示为“Unschedulable”,这意味着默认情况下不会将Pod调度到这些节点。

worker

具有worker角色的节点运行Kubernetes节点组件。 有关组件包括kubelet,kube-proxy,Container runtime。

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker your-user

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.
