k8 installation​

Install via KubeKey​

kubekey

# 	Kubernetes 版本 ≥ 1.18
# socat	必须安装
# conntrack	必须安装
# 验证: socat -V && conntrack --version
sudo apt install socat conntrack -y


# 使用脚本获取 KubeKey
export KKZONE=cn
curl -sfL https://get-kk.kubesphere.io | sh -
# 创建集群(快速开始)
export KKZONE=cn
# ./kk create cluster [--with-kubernetes version] [--with-kubesphere version]
# 使用默认版本创建一个纯 Kubernetes 集群
./kk create cluster
# 创建一个部署了 KubeSphere 的 Kubernetes 集群 （例如 --with-kubesphere v3.1.0）
./kk create cluster --with-kubesphere
# 使用配置文件创建集群
./kk create cluster -f ~/myfolder/config-sample.yaml


# Console: http://10.0.16.146:30880
# Account: admin
# Password: P@88w0rd

# Please check the result using the command:
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f


# 删除集群
./kk delete cluster
# 有时候可能还需要主动删除这个文件夹
rm -rf /etc/kubernetes/

Problem​

# FATA[0000] validate service connection: validate CRI v1 image API for endpoint "unix://run/containerd/containerd.sock": rpc error: code = Unimplemented desc = unknown service runtime.v1. mageService: Process Excludes with status 1

vi /etc/containerd/config. oml

# disabled_plugins = []# Ensure CRI
# Restart Containerd：
sudo systemctl start containerd


## /etc/etc/etcd. nv (this file may need to be created manually) (file in the current document directory)

# Certificate question
sudo mkdir -p /etc/ssl/certs
sudo chmod 755 /etc/ssl/certs
apt update && sudo apt install ca-certificates
sudo update-ca-certificates
## If docker is used, then you may need to restart docker (systemctl restart docker)
