Basic Commands (Beginner): create Create a resource from a file or from stdin. expose 使用 replication controller, service, deployment 或者 pod 并暴露它作为一个 新的 Kubernetes Service run 在集群中运行一个指定的镜像 set 为 objects 设置一个指定的特征 run-container 在集群中运行一个指定的镜像. This command is deprecated, use "run" instead
Basic Commands (Intermediate): get 显示一个或更多 resources explain 查看资源的文档 edit 在服务器上编辑一个资源 delete Delete resources by filenames, stdin, resources and names, or by resources and label selector
Deploy Commands: rollout Manage the rollout of a resource rolling-update 完成指定的 ReplicationController 的滚动升级 scale 为 Deployment, ReplicaSet, Replication Controller 或者 Job 设置一个新的副本数量 autoscale 自动调整一个 Deployment, ReplicaSet, 或者 ReplicationController 的副本数量
Troubleshooting and Debugging Commands: describe 显示一个指定 resource 或者 group 的 resources 详情 logs 输出容器在 pod 中的日志 attach Attach 到一个运行中的 container exec 在一个 container 中执行一个命令 port-forward Forward one or more local ports to a pod proxy 运行一个 proxy 到 Kubernetes API server cp 复制 files 和 directories 到 containers 和从容器中复制 files 和 directories. auth Inspect authorization
Settings Commands: label 更新在这个资源上的 labels annotate 更新一个资源的注解 completion Output shell completion code for the specified shell (bash or zsh)
Other Commands: api-versions Print the supported API versions on the server, in the form of "group/version" config 修改 kubeconfig 文件 help Help about any command plugin Runs a command-line plugin version 输出 client 和 server 的版本信息
Usage: kubectl [flags] [options]
Use "kubectl <command> --help" for more information about a given command. Use "kubectl options" for a list of global command-line options (applies to all commands).
Examples: # List all pods in ps output format. kubectl get pods # List all pods in ps output format with more information (such as node name). kubectl get pods -o wide # List a single replication controller with specified NAME in ps output format. kubectl get replicationcontroller web # List a single pod in JSON output format. kubectl get -o json pod web-pod-13je7 # List a pod identified by type and name specified in"pod.yaml"in JSON output format. kubectl get -f pod.yaml -o json # Return only the phase value of the specified pod. kubectl get -o template pod/web-pod-13je7 --template={{.status.phase}} # List all replication controllers and services together in ps output format. kubectl get rc,services # List one or more resources by their type and names. kubectl get rc/web service/frontend pods/web-pod-13je7 # List all resources with different types. kubectl get all
scale-扩缩容
Set a new size for a Deployment, ReplicaSet, Replication Controller, or StatefulSet.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
Examples: # Scale a replicaset named 'foo' to 3. kubectl scale --replicas=3 rs/foo
# Scale a resource identified by type and name specified in "foo.yaml" to 3. kubectl scale --replicas=3 -f foo.yaml
# If the deployment named mysql's current size is 2, scale mysql to 3. kubectl scale --current-replicas=2 --replicas=3 deployment/mysql
for i in `kubectl get deployment | awk '{print $1}' |grep -v NAME`; do kubectl scale Deployment $i --replicas=1 done
exec-在container中执行命令
Execute a command in a container.
1 2 3 4 5 6 7 8 9
Options: -c, --container='': Container name. If omitted, the first container in the pod will be chosen -p, --pod='': Pod name -i, --stdin=false: Pass stdin to the container -t, --tty=false: Stdin is a TTY Examples: kubectl exec 123456-7890 -c ruby-container -it -- bash -il Usage: kubectl exec POD [-c CONTAINER] -- COMMAND [args...] [options]
