kubernetes资源管理平台ratel

ratel是一个kubernetes集群资源管理平台,使用它可以对多种资源进行创建查看修改和删除操作，支持配置多个集群的管理。

官网：https://github.com/dotbalo/ratel-doc

需要注意在安装时配置 server.yaml

# 先拷贝集群配置文件到当前目录：cp /root/.kube/config test1.config
# kubeConfigPath 按如下去写，不用在/mnt下手动创建test1.config
# 不用配置serverAdminUser serverAdminPassword serverAdminToken，使用kubeConfigPath连接集群
[root@k8smaster ratel]# cat servers.yaml
- serverName: 'test1'serverAddress: '集群访问地址，可以用kube cluster-info查看'#serverAdminUser: 'xxx'#serverAdminPassword: 'xxx#'serverAdminToken: 'null'serverDashboardUrl: "部署的集群可视化监控平台dashboard地址"production: 'false'kubeConfigPath: "/mnt/test1.config"# 启动时候启动创建server.yaml和test1.config
kubectl create secret generic ratel-config  --from-file=test1.config  --from-file=servers.yaml -n kube-system

如果使用ingress访问，在启动ingress前需要安装ingress-controller(不是系统controller,默认没有安装)

ingress-controller.yaml
