创建集群

要使用 Helm，我们首先需要一个 Kubernetes 集群环境。在本课程中，我们将使用 kind 作为本地集群工具。让我们来看看具体如何操作。

管理 Kubernetes 集群

创建集群

我们可以通过在下方终端中执行以下命令来创建一个集群：

1kind create cluster

接着运行：

1docker ps

输出结果如下：

1CONTAINER ID   IMAGE                  STATUS  
2efcf4b73c74d   kindest/node:v1.21.1   Up 8 minutes  

我们还可以查看日志，确认一切是否正常运行：

1docker logs kind-control-plane

输出内容如下：

1INFO: ensuring we can execute mount/umount even with userns-remap
2INFO: remounting /sys read-only
3INFO: making mounts shared
4INFO: detected cgroup v1
5INFO: fix cgroup mounts for all subsystems
6INFO: clearing and regenerating /etc/machine-id
