Update fields of a resource
Update fields of a resource using strategic merge patch, a JSON merge patch, or a JSON patch.
JSON and YAML formats are accepted.
Note: Strategic merge patch is not supported for custom resources.
ergo kubectl patch (-f FILENAME | TYPE NAME) [-p PATCH|--patch-file FILE]
# Partially update a node using a strategic merge patch, specifying the patch as JSON
kubectl patch node k8s-node-1 -p '{"spec":{"unschedulable":true}}'
# Partially update a node using a strategic merge patch, specifying the patch as YAML
kubectl patch node k8s-node-1 -p $'spec:\n 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"}]'
# Update a deployment's replicas through the scale subresource using a merge patch.
kubectl patch deployment nginx-deployment --subresource='scale' --type='merge' -p '{"spec":{"replicas":2}}'
--allow-missing-template-keys 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. (default true)
--dry-run string[="unchanged"] Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it. If server strategy, submit server-side request without persisting the resource. (default "none")
--field-manager string Name of the manager used to track field ownership. (default "kubectl-patch")
-f, --filename strings Filename, directory, or URL to files identifying the resource to update
-h, --help help for patch
-k, --kustomize string Process the kustomization directory. This flag can't be used together with -f or -R.
--local If true, patch will operate on the content of the file, not the server-side resource.
-o, --output string Output format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).
-p, --patch string The patch to be applied to the resource JSON file.
--patch-file string A file containing a patch to be applied to the resource.
-R, --recursive Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
--show-managed-fields If true, keep the managedFields when printing objects in JSON or YAML format.
--subresource string If specified, patch will operate on the subresource of the requested object. Must be one of [status scale]. This flag is alpha and may change in the future.
--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")
--as string Username to impersonate for the operation. User could be a regular user or a service account in a namespace.
--as-group stringArray Group to impersonate for the operation, this flag can be repeated to specify multiple groups.
--as-uid string UID to impersonate for the operation.
--cache-dir string Default cache directory (default "/Users/ysicing/.kube/cache")
--certificate-authority string Path to a cert file for the certificate authority
--client-certificate string Path to a client certificate file for TLS
--client-key string Path to a client key file for TLS
--cluster string The name of the kubeconfig cluster to use
--config string The ergo config file to use (default "/Users/ysicing/.ergo/config/ergo.yml")
--context string The name of the kubeconfig context to use
--debug Prints the stack trace if an error occurs
--disable-compression If true, opt-out of response compression for all requests to the server
--insecure-skip-tls-verify If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
--kubeconfig string Path to the kubeconfig file to use for CLI requests.
--match-server-version Require server version to match client version
-n, --namespace string If present, the namespace scope for this CLI request
--password string Password for basic authentication to the API server
--profile string Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex) (default "none")
--profile-output string Name of the file to write the profile to (default "profile.pprof")
--request-timeout string The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0")
-s, --server string The address and port of the Kubernetes API server
--silent Run in silent mode and prevents any ergo log output except panics & fatals
--tls-server-name string Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used
--token string Bearer token for authentication to the API server
--user string The name of the kubeconfig user to use
--username string Username for basic authentication to the API server
--warnings-as-errors Treat warnings received from the server as errors and exit with a non-zero exit code
- ergo kubectl - Kubectl controls the Kubernetes cluster manager
