See Also kubectl set - Set specific features on objects kubectl taint Synopsis Update the taints on one or more nodes. A taint consists of a key, value, and effect. As an argument here, it is expressed as key=value:effect. The key must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 253 characters. Optionally, the key can begin with a DNS subdomain prefix and a single '/', like example.com/my-app. The value is optional. If given, it must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters. The effect must be NoSchedule, PreferNoSchedule or NoExecute. Currently taint can only apply to node. kubectl taint NODE NAME KEY_1=VAL_1:TAINT_EFFECT_1 ...

--allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats. --dry-run string[="unchanged"]     Default: "none" Must be "none", "server", or "client".

The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview]. --validate string[="strict"]     Default: "strict" Must be one of: strict (or true), warn, ignore (or false). "true" or "strict" will use a schema to validate the input and fail the request if invalid. It will perform server side validation if ServerSideFieldValidation is enabled on the api-server, but will fall back to less reliable client-side validation if not. "warn" will warn about unknown or duplicate fields without blocking the request if server- side field validation is enabled on the API server, and behave as "ignore" otherwise

"false" or "ignore" will not perform any schema validation, silently dropping any unknown or duplicate fields. --as string Username to impersonate for the operation.

JSONPath Support Kubectl supports JSONPath template. JSONPath template is composed of JSONPath expressions enclosed by curly braces {}. Kubectl uses JSONPath expressions to filter on specific fields in the JSON object and format the output. In addition to the original JSONPath template syntax, the following functions and syntax are valid: Use double quotes to quote text inside JSONPath expressions. Use the range , end operators to iterate lists. Use negative slice indices to step backwards through a list. Negative indices do not "wrap around" a list and are valid as long as -index + listLength >=

0 . Note: The $ operator is optional since the expression always starts from the root object by default. The result object is printed as its String() function. Given the JSON input: { "kind" : "List" , "items" :[ {• • • • • • • • • • • • • • • • • • • • • • • 1. 2. 3. •

"kind" :"None" , "metadata" :{ "name" :"127.0.0.1" , "labels" :{ "kubernetes.io/hostname" :"127.0.0.1" } }, "status" :{ "capacity" :{"cpu" :"4"}, "addresses" :[{"type" : "LegacyHostIP" , "address" :"127.0.0.1" }] } }, { "kind" :"None" , "metadata" :{"name" :"127.0.0.2" }, "status" :{ "capacity" :{"cpu" :"8"}, "addresses" :[ { "type" : "LegacyHostIP" , "address" :"127.0.0.2" }, { "type" : "another" , "address" :"127.0.0.3" } ] } } ], "users" :[ { "name" : "myself" , "user" : {} }, { "name" : "e2e" , "user" : {"username" : "admin" , "password" : "secret" } } ] } Function Description Example Result text the plain text kind is {.kind} kind is List @the current object{@} the same as input . or [] child operator {.kind} , {['kind']} or {['name\.type']} List ..recursive descent{..name}127.0.0.1

This in turn means that you mus

t use a single quote or escaped double quote around any literals in the template. For example: kubectl get pods -o=jsonpath= "{range .items[*]}{.metadata.name}{'\t'}{.status.startTime}{'\n'} {end}" kubectl get pods -o=jsonpath= "{range .items[*]}{.metadata.name}{\" \t\"}{.status.startTime}{\" \n\"} {end}" Note: JSONPath regular expressions are not supported. If you want to match using regular expressions, you can use a tool such as jq. # kubectl does not support regular expressions for JSONpath output # The following command does not work kubectl get pods -o jsonpath ='{.items[?(@.metadata.name=~/^test$/)].metadata.name}' # The following command achieves the desired result kubectl get pods -o json | jq -r '.items[] | select(.metadata.name | test("test-")).metadata.name' kubectl for Docker Users You can use the Kubernetes command line tool kubectl to interact with the API Server. Using kubectl is straightforward if you are familiar with the Docker command line tool. However, there are

a few differences between the Docker commands and the kubectl commands. The following sections show a Docker sub-command and describe the equivalent kubectl command

docker run To run an nginx Deployment and expose the Deployment, see kubectl create deployment . docker: docker run -d --restart =always -e DOMAIN =cluster --name nginx-app -p 80:80 nginx 55c103fa129692154a7652490236fee9be47d70a8dd562281ae7d2f9a339a6db docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 55c103fa1296 nginx "nginx -g 'daemon of..." 9 seconds ago Up 9 seconds 0.0.0.0:80->80/tcp nginx-app kubectl: # start the pod running nginx kubectl create deployment --image =nginx nginx-app deployment.apps/nginx-app created # add env to nginx-app kubectl set env deployment/nginx-app DOMAIN =cluster deployment.apps/nginx-app env updated Note: kubectl commands print the type and name of the resource created or mutated, which can then be used in subsequent commands. You can expose a new Service after a Deployment is created. # expose a port through with a ser

vice kubectl expose deployment nginx-app --port =80 --name =nginx-http service "nginx-http" exposed By using kubectl, you can create a Deployment to ensure that N pods are running nginx, where N is the number of replicas stated in the spec and defaults to 1. You can also create a service with a selector that matches the pod labels. For more information, see Use a Service to Access an Application in a Cluster . By default images run in the background, similar to docker run -d ... . To run things in the foreground, use kubectl run to create pod: kubectl run [-i] [--tty] --attach <name> --image =<image> Unlike docker run ... , if you specify --attach , then you attach stdin , stdout and stderr . You cannot control which streams are attached ( docker -a ... ). To detach from the container, you can type the escape sequence Ctrl+P followed by Ctrl+Q. docker ps To list what is currently running, see kubectl get

There is a slight difference between pods and containers; by default pods do not terminate if their processes exit. Instead the pods restart the process. This is similar to the docker run option --restart=always with one major difference. In docker, the output for each invocation of the process is concatenated, but for Kubernetes, each invocation is separate. To see the output from a previous run in Kubernetes, do this: kubectl logs --previous nginx-app-zibvs 10.240.63.110 - - [14/Jul/2015:01:09:01 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.26.0" "-" 10.240.63.110 - - [14/Jul/2015:01:09:02 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.26.0" "-" For more information, see Logging Architecture . docker stop and docker rm To stop and delete a running process, see kubectl delete . docker: docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a9ec34d98787 nginx "nginx -g 'daem

Note: When you use kubectl, you don't delete the pod directly. You have to first delete the Deployment that owns the pod. If you delete the pod directly, the Deployment recreates the pod. docker login There is no direct analog of docker login in kubectl.

Using kubectl in Reusable Scripts For a stable output in a script: Request one of the machine-oriented output forms, such as -o name , -o json , -o yaml , -o go-template , or -o jsonpath . Fully-qualify the version. For example, jobs.v1.batch/myjob . This will ensure that kubectl does not use its default version that can change over time. Don't rely on context, preferences, or other implicit states.• •

Subresources You can use the --subresource beta flag for kubectl commands like get, patch , edit and replace to fetch and update subresources for all resources that support them. Currently, only the status and scale subresources are supported. For kubectl edit , the scale subresource is not supported. If you use --subresource with kubectl edit and specify scale as the subresource, the command will error out. The API contract against a subresource is identical to a full resource. While updating the status subresource to a new value, keep in mind that the subresource could be potentially reconciled by a controller to a different value. Best Practices kubectl run For kubectl run to satisfy infrastructure as code: Tag the image with a version-specific tag and don't move that tag to a new version. For example, use :v1234 , v1.2.3 , r03062016-1-4 , rather than :latest (For more information, see Best Practices for Configuration ). Check in the script for an image that is heavily

parameterized. Switch to configuration files checked into source control for features that are needed, but not expressible via kubectl run flags. You can use the --dry-run=client flag to preview the object that would be sent to your cluster, without really submitting it. kubectl apply You can use kubectl apply to create or update resources. For more information about using kubectl apply to update resources, see Kubectl Book .

Feature Gates This page contains an overview of the various feature gates an administrator can specify on different Kubernetes components. See feature stages for an explanation of the stages for a feature. Overview Feature gates are a set of key=value pairs that describe Kubernetes features. You can turn these features on or off using the --feature-gates command line flag on each Kubernetes component. Each Kubernetes component lets you enable or disable a set of feature gates that are relevant to that component. Use -h flag to see a full set of feature gates for all components. To set feature gates for a component, such as kubelet, use the --feature-gates flag assigned to a list of feature pairs: --feature-gates =...,GracefulNodeShutdown =true The following tables are a summary of the feature gates that you can set on different Kubernetes components. The "Since" column contains the Kubernetes release when a feature is introduced or its release stage is changed. The "Until" column, i

f not empty, contains the last Kubernetes release in which you can still use a feature gate. If a feature is in the Alpha or Beta state, you can find the feature listed in the Alpha/Beta feature gate table . If a feature is stable you can find all stages for that feature listed in the Graduated/ Deprecated feature gate table . The Graduated/Deprecated feature gate table also lists deprecated and withdrawn features. Note: For a reference to old feature gates that are removed, please refer to feature gates removed .
