Display one or many resources
Display one or many resources.
Possible resource types include (case insensitive): pods (po), services (svc), deployments, replicasets (rs), replicationcontrollers (rc), nodes (no), events (ev), limitranges (limits), persistentvolumes (pv), persistentvolumeclaims (pvc), resourcequotas (quota), namespaces (ns), serviceaccounts (sa), ingresses (ing), horizontalpodautoscalers (hpa), daemonsets (ds), configmaps, componentstatuses (cs), endpoints (ep), and secrets.
By specifying the output as ‘template’ and providing a Go template as the value of the –template flag, you can filter the attributes of the fetched resource(s).
kubectl get [(-o|--output=)json|yaml|wide|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=...] (TYPE [NAME | -l label] | TYPE/NAME ...) [flags]
# 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=
# 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
--all-namespaces[=false]: If present, list the requested object(s) across all namespaces. Namespace in current context is ignored even if specified with --namespace.
--export[=false]: If true, use 'export' for the resources. Exported resources are stripped of cluster-specific information.
-f, --filename=[]: Filename, directory, or URL to a file identifying the resource to get from a server.
--include-extended-apis[=true]: If true, include definitions of new APIs via calls to the API server. [default true]
-L, --label-columns=[]: Accepts a comma separated list of labels that are going to be presented as columns. Names are case-sensitive. You can also use multiple flag statements like -L label1 -L label2...
--no-headers[=false]: 当使用默认输出格式时不打印标题栏。
-o, --output="": Output format. One of: json|yaml|wide|name|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://releases.k8s.io/release-1.3/docs/user-guide/jsonpath.md].
--output-version="": Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
-R, --recursive[=false]: Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
-l, --selector="": Selector (label query) to filter on
-a, --show-all[=false]: When printing, show all resources (default hide terminated pods.)
--show-labels[=false]: When printing, show all labels as the last column (default hide labels column)
--sort-by="": If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
--template="": Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].
-w, --watch[=false]: After listing/getting the requested object, watch for changes.
--watch-only[=false]: Watch for changes to the requested object(s), without listing/getting first.
--alsologtostderr[=false]: 同时输出日志到标准错误控制台和文件。
--certificate-authority="": 用以进行认证授权的.cert文件路径。
--client-certificate="": TLS使用的客户端证书路径。
--client-key="": TLS使用的客户端密钥路径。
--cluster="": 指定使用的kubeconfig配置文件中的集群名。
--context="": 指定使用的kubeconfig配置文件中的环境名。
--insecure-skip-tls-verify[=false]: 如果为true,将不会检查服务器凭证的有效性,这会导致你的HTTPS链接变得不安全。
--kubeconfig="": 命令行请求使用的配置文件路径。
--log-backtrace-at=:0: 当日志长度超过定义的行数时,忽略堆栈信息。
--log-dir="": 如果不为空,将日志文件写入此目录。
--log-flush-frequency=5s: 刷新日志的最大时间间隔。
--logtostderr[=true]: 输出日志到标准错误控制台,不输出到文件。
--match-server-version[=false]: 要求服务端和客户端版本匹配。
--namespace="": 如果不为空,命令将使用此namespace。
--password="": API Server进行简单认证使用的密码。
-s, --server="": Kubernetes API Server的地址和端口号。
--stderrthreshold=2: 高于此级别的日志将被输出到错误控制台。
--token="": 认证到API Server使用的令牌。
--user="": 指定使用的kubeconfig配置文件中的用户名。
--username="": API Server进行简单认证使用的用户名。
--v=0: 指定输出日志的级别。
--vmodule=: 指定输出日志的模块,格式如下:pattern=N,使用逗号分隔。
