20230407kubekey搭建k8s

视频版

https://www.bilibili.com/video/BV1gL411Y75L

背景

20230204尝试搭建k8s青春版

上次尝试了k3s，本来计划是尝试原版k8s，但看了下文档感觉略麻烦，我决定放弃。。。。

按上次eric的建议这次尝试玩下kubekey

安装准备

环境要求

Ubuntu 16.04，18.04，20.04CPU：2 核，内存：4 G，硬盘：40 G

机器节点2c4g * 3

所有节点必须都能通过 SSH 访问。
所有节点时间同步。
所有节点都应使用 sudo/curl/openssl/tar

域名分配

k8s1.k8s.local

k8s2.k8s.local

k8s3.k8s.local

kubesphere.k8s.local

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

Alternatively, if you are the root user, you can run:

  export KUBECONFIG=/etc/kubernetes/admin.conf

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 control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:

  kubeadm join kubesphere.k8s.local:6443 --token 71j95c.vwt766fyex29car8 \
        --discovery-token-ca-cert-hash sha256:57fac9b5408266f709d667f092e5fb7e140e56480e9d2d10796007af241202a8 \
        --control-plane

Then you can join any number of worker nodes by running the following on each as root:

kubeadm join kubesphere.k8s.local:6443 --token 71j95c.vwt766fyex29car8 \
        --discovery-token-ca-cert-hash sha256:57fac9b5408266f709d667f092e5fb7e140e56480e9d2d10796007af241202a8
