kubeasz单机群下部署kubesphere－出错后的修改脚本

使用kubeasz在单机k8s群,具体的步骤

# https://github.com/easzlab/kubeasz

chmod +x ./easzup2.2.1

echo "#########download packages#########"
# 1 下载安装包
# docker: 19.03.8
# k8s: 1.18.3
./easzup2.2.1 -D

# 2 rpm包之类
# 可选下载离线系统包 (适用于无法使用 yum/apt 仓库情形)
./easzup2.2.1 -P

echo "#########run ansible controller#########"
# 3 容器化运行 kubeasz，详见文档
./easzup2.2.1 -S

echo "#########setup aio#########"
sed -i 's/^INSTALL_SOURCE.*$/INSTALL_SOURCE: "offline"/g' /etc/ansible/roles/chrony/defaults/main.yml
sed -i 's/^INSTALL_SOURCE.*$/INSTALL_SOURCE: "offline"/g' /etc/ansible/roles/ex-lb/defaults/main.yml
sed -i 's/^INSTALL_SOURCE.*$/INSTALL_SOURCE: "offline"/g' /etc/ansible/roles/kube-node/defaults/main.yml
sed -i 's/^INSTALL_SOURCE.*$/INSTALL_SOURCE: "offline"/g' /etc/ansible/roles/prepare/defaults/main.yml
# 4 使用默认配置安装 aio 集群
docker exec -it kubeasz easzctl start-aio

在上面的群上安装kubesphere 安装前提条件 https://kubesphere.io/zh/docs/installing-on-kubernetes/introduction/prerequisites/ kubectl apply -f https://raw.githubusercontent.com/kubesphere/ks-installer/v3.0.0/deploy/kubesphere-installer.yaml kubectl apply -f https://raw.githubusercontent.com/kubesphere/ks-installer/v3.0.0/deploy/cluster-configuration.yaml

安装后，出现问题，没有minikube方便，看日志需要配置存储

如下提供了一个主机的sc.yaml

安装kubesphere步骤

# kubectl --kubeconfig=./config  #在没有预先配置的kubeconfig的主机上执行时可以使用这个方式
kubectl delete -f kubesphere-installer.yaml
kubectl delete -f cluster-configuration.yaml
kubectl delete -f sc.yaml
rm -rf /opt/data/*

mkdir -p /opt/data/{redis,etcd,minio,mysql,openldap,prometues}
kubectl apply -f sc.yaml #需要在k8s dashboard中看下pvc的状态是否正常
kubectl apply -f kubesphere-installer.yaml
kubectl apply -f cluster-configuration.yaml

sleep 5
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f

kubesphere / ks-installer
