Run a particular image on the cluster
Create and run a particular image in a pod.

# Start a nginx pod
kubectl run nginx --image=nginx
# Start a hazelcast pod and let the container expose port 5701
kubectl run hazelcast --image=hazelcast/hazelcast --port=5701
# Start a hazelcast pod and set environment variables "DNS_DOMAIN=cluster" and "POD_NAMESPACE=default" in the container
kubectl run hazelcast --image=hazelcast/hazelcast --env="DNS_DOMAIN=cluster" --env="POD_NAMESPACE=default"
# Start a hazelcast pod and set labels "app=hazelcast" and "env=prod" in the container
kubectl run hazelcast --image=hazelcast/hazelcast --labels="app=hazelcast,env=prod"
# Dry run; print the corresponding API objects without creating them
kubectl run nginx --image=nginx --dry-run=client
# Start a nginx pod, but overload the spec with a partial set of values parsed from JSON
kubectl run nginx --image=nginx --overrides='{ "apiVersion": "v1", "spec": { ... } }'
# Start a busybox pod and keep it in the foreground, don't restart it if it exits
kubectl run -i -t busybox --image=busybox --restart=Never
# Start the nginx pod using the default command, but use custom arguments (arg1 .. argN) for that command
kubectl run nginx --image=nginx -- <arg1> <arg2> ... <argN>
# Start the nginx pod using a different command and custom arguments
kubectl run nginx --image=nginx --command -- <cmd> <arg1> ... <argN>
--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)
--annotations stringArray Annotations to apply to the pod.
--attach If true, wait for the Pod to start running, and then attach to the Pod as if 'kubectl attach ...' were called. Default false, unless '-i/--stdin' is set, in which case the default is true. With '--restart=Never' the exit code of the container process is returned.
--command If true and extra arguments are present, use them as the 'command' field in the container, rather than the 'args' field which is the default.
--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")
--env stringArray Environment variables to set in the container.
--expose --port If true, create a ClusterIP service associated with the pod. Requires --port.
--field-manager string Name of the manager used to track field ownership. (default "kubectl-run")
-h, --help help for run
--image string The image for the container to run.
--image-pull-policy string The image pull policy for the container. If left empty, this value will not be specified by the client and defaulted by the server.
-l, --labels string Comma separated labels to apply to the pod. Will override previous values.
--leave-stdin-open If the pod is started in interactive mode or with stdin, leave stdin open after the first attach completes. By default, stdin will be closed after the first attach completes.
-o, --output string Output format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).
--override-type string The method used to override the generated object: json, merge, or strategic. (default "merge")
--overrides string An inline JSON override for the generated object. If this is non-empty, it is used to override the generated object. Requires that the object supply a valid apiVersion field.
--pod-running-timeout duration The length of time (like 5s, 2m, or 3h, higher than zero) to wait until at least one pod is running (default 1m0s)
--port string The port that this container exposes.
--privileged If true, run the container in privileged mode.
-q, --quiet If true, suppress prompt messages.
--restart string The restart policy for this Pod. Legal values [Always, OnFailure, Never]. (default "Always")
--rm If true, delete the pod after it exits. Only valid when attaching to the container, e.g. with '--attach' or with '-i/--stdin'.
--save-config If true, the configuration of current object will be saved in its annotation. Otherwise, the annotation will be unchanged. This flag is useful when you want to perform kubectl apply on this object in the future.
--show-managed-fields If true, keep the managedFields when printing objects in JSON or YAML format.
-i, --stdin Keep stdin open on the container in the pod, even if nothing is attached.
--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].
-t, --tty Allocate a TTY for the container in the pod.
--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
