kubectl wait

Synopsis

Experimental: Wait for a specific condition on one or many resources.

The command takes multiple resources and waits until the specified condition is seen in the Status field of every given resource.

Alternatively, the command can wait for the given set of resources to be created or deleted by providing the "create" or "delete" keyword as the value to the --for flag.

A successful message will be printed to stdout indicating when the specified condition has been met. You can use -o option to change to output destination.

kubectl wait ([-f FILENAME] | resource.group/resource.name | resource.group [(-l label | --all)]) [--for=create|--for=delete|--for condition=available|--for=jsonpath='{}'[=value]]

Examples

  # Wait for the pod "busybox1" to contain the status condition of type "Ready"
  kubectl wait --for=condition=Ready pod/busybox1
  
  # The default value of status condition is true; you can wait for other targets after an equal delimiter (compared after Unicode simple case folding, which is a more general form of case-insensitivity)
  kubectl wait --for=condition=Ready=false pod/busybox1
  
  # Wait for the pod "busybox1" to contain the status phase to be "Running"
  kubectl wait --for=jsonpath='{.status.phase}'=Running pod/busybox1
  
  # Wait for pod "busybox1" to be Ready
  kubectl wait --for='jsonpath={.status.conditions[?(@.type=="Ready")].status}=True' pod/busybox1
  
  # Wait for the service "loadbalancer" to have ingress
  kubectl wait --for=jsonpath='{.status.loadBalancer.ingress}' service/loadbalancer
  
  # Wait for the secret "busybox1" to be created, with a timeout of 30s
  kubectl create secret generic busybox1
  kubectl wait --for=create secret/busybox1 --timeout=30s
  
  # Wait for the pod "busybox1" to be deleted, with a timeout of 60s, after having issued the "delete" command
  kubectl delete pod/busybox1
  kubectl wait --for=delete pod/busybox1 --timeout=60s

Options

--all
	Select all resources in the namespace of the specified resource types
-A, --all-namespaces
	If present, list the requested object(s) across all namespaces. Namespace in current context is ignored even if specified with --namespace.

	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.
--field-selector string
	Selector (field query) to filter on, supports '=', '==', and '!='.(e.g. --field-selector key1=value1,key2=value2). The server only supports a limited number of field queries per type.
-f, --filename strings
	identifying the resource.
--for string
	The condition to wait on: [create\|delete\|condition=condition-name[=condition-value]\|jsonpath='{JSONPath expression}'=[JSONPath value]]. The default condition-value is true. Condition values are compared after Unicode simple case folding, which is a more general form of case-insensitivity.
-h, --help
	help for wait
--local
	If true, annotation will NOT contact api-server but run locally.
-o, --output string
	Output format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).

--context string
	The name of the kubeconfig context to use
--default-not-ready-toleration-seconds int Default: 300
	Indicates the tolerationSeconds of the toleration for notReady:NoExecute that is added by default to every pod that does not already have such a toleration.
--default-unreachable-toleration-seconds int Default: 300
	Indicates the tolerationSeconds of the toleration for unreachable:NoExecute that is added by default to every pod that does not already have such a toleration.
--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

--match-server-version
	Require server version to match client version
-n, --namespace string
	If present, the namespace scope for this CLI request

--profile string Default: "none"
	Name of profile to capture. One of (none\|cpu\|heap\|goroutine\|threadcreate\|block\|mutex)
--profile-output string Default: "profile.pprof"
	Name of the file to write the profile to
--request-timeout string Default: "0"
	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.
-s, --server string
	The address and port of the Kubernetes API server
--storage-driver-buffer-duration duration Default: 1m0s
