kubectl patch (-f FILENAME | TYPE NAME) -p PATCH
Examples
# Partially update a node using strategic merge patch
kubectl patch node k8s-node-1 -p '{"spec":{"unschedulable":true}}'
# Partially update a node identified by the type and name specified in "node.json" using strategic merge patch
kubectl patch -f node.json -p '{"spec":{"unschedulable":true}}'
# Update a container's image; spec.containers[*].name is required because it's a merge key
kubectl patch pod valid-pod -p '{"spec":{"containers":[{"name":"kubernetes-serve-hostname","image":"new image"}]}}'
# Update a container's image using a json patch with positional arrays
kubectl patch pod valid-pod --type='json' -p='[{"op": "replace", "path": "/spec/containers/0/image", "value":"new image"}]'
Options
-f, --filename stringSlice Filename, directory, or URL to files identifying the resource to update
--local If true, patch will operate on the content of the file, not the server-side resource.
--no-headers When using the default or custom-column output format, don't print headers.
-o, --output string Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
--output-version string Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
-p, --patch string The patch to be applied to the resource JSON file.
--record Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists.
-R, --recursive Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
-a, --show-all When printing, show all resources (default hide terminated pods.)
--show-labels When printing, show all labels as the last column (default hide labels column)
--sort-by string 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 string 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].
--type string The type of patch being provided; one of [json merge strategic] (default "strategic")
