使用多合一镜像运行集群 #

本文档介绍了使用多合一镜像创建集群的步骤。

入门 #

docker run --rm -it -p 8080:8080 registry.k8s.io/kwok/cluster:v0.4.0-k8s.v1.28.0

Cluster is creating                                                       cluster=kwok
Cluster is created                                           elapsed=0.3s cluster=kwok
Cluster is starting                                                       cluster=kwok
Cluster is started                                           elapsed=0.7s cluster=kwok
You can now use your cluster with:

	kubectl cluster-info --context kwok-kwok

Thanks for using kwok!

# The above example works if your host's port is the same as the container's,
# otherwise, change it to your host's port

在 Pod 中使用 #

如果您在 Pod 中使用多合一镜像，则需要禁用服务帐户令牌，否则集群可能无法正常工作。

...
spec:
  automountServiceAccountToken: false
...

或者

删除服务帐户令牌文件 /var/run/secrets/kubernetes.io/serviceaccount/token。

后续步骤 #

现在，您可以使用 kwok 管理 Kubernetes 集群中的节点和 Pod。
