OC-ADM-RESTART-KUBELET(1)

💅 oc adm restart-kubelet 💅

okay bestie, welcome to the OC ADM(1) manual page for oc adm restart-kubelet — we're doing every flag, every default, every little detail, and we're gonna make it cute 🫶✨

---

👑 NAME 👑

oc adm restart-kubelet — Restart kubelet on the specified nodes

---

✨ SYNOPSIS ✨

oc adm restart-kubelet [OPTIONS]

---

🦋 DESCRIPTION 🦋

So the page says: regenerate certificates provided by an OCP v4 cluster. Yes, literally that's the description — we're not changing the facts, bestie 💀

This command does not wait for changes to be acknowledged by the cluster. Some may take a very long time to roll out into a cluster, with different operators and operands involved for each.

Experimental: This command is under active development and may change without notice. Not me being dramatic — that's literally in the page 🙈

---

💅 OPTIONS 💅

• --all=false — Select all resources in the namespace of the specified resource types
• --allow-missing-template-keys=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.
• --command="" — command to run after the kubelet stops, before the kubelet starts.
• --directive="" — run a well-known command while restarting kubelets: RemoveKubeletKubeconfig
• --dry-run=false — Set to true to use server-side dry run.
• --field-selector="" — 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=[] — identifying the resource.
• --local=false — If true, annotation will NOT contact api-server but run locally.
• -o, --output="" — Output format. One of: (json, yaml, kyaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).
• --parallelism="10%" — parallelism is a raw number or a percentage of the nodes to work with concurrently.
• -R, --recursive=true — Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
• -l, --selector="" — Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2)
• --show-managed-fields=false — If true, keep the managedFields when printing objects in JSON or YAML format.
• --template="" — 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].

🌸 OPTIONS INHERITED FROM PARENT COMMANDS 🌸

• --as="" — Username to impersonate for the operation. User could be a regular user or a service account in a namespace.
• --as-group=[] — Group to impersonate for the operation, this flag can be repeated to specify multiple groups.
• --as-uid="" — UID to impersonate for the operation.
• --as-user-extra=[] — User extras to impersonate for the operation, this flag can be repeated to specify multiple values for the same key.
• --cache-dir="/homeless-shelter/.kube/cache" — Default cache directory
• --certificate-authority="" — Path to a cert file for the certificate authority
• --client-certificate="" — Path to a client certificate file for TLS
• --client-key="" — Path to a client key file for TLS
• --cluster="" — The name of the kubeconfig cluster to use
• --context="" — The name of the kubeconfig context to use
• --disable-compression=false — If true, opt-out of response compression for all requests to the server
• --insecure-skip-tls-verify=false — If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure

⚠️ bestie, that --insecure-skip-tls-verify=false one is literally saying it makes your HTTPS connections insecure if true. Read the flag, love her, respect her 💀

• --kubeconfig="" — Path to the kubeconfig file to use for CLI requests.
• --kuberc="" — Path to the kuberc file to use for preferences. This can be disabled by exporting KUBECTL_KUBERC=false feature gate or turning off the feature KUBERC=off.
• --match-server-version=false — Require server version to match client version
• -n, --namespace="" — If present, the namespace scope for this CLI request
• --profile="none" — Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex)
• --profile-output="profile.pprof" — Name of the file to write the profile to
• --request-timeout="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="" — The address and port of the Kubernetes API server
• --tls-server-name="" — Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used
• --token="" — Bearer token for authentication to the API server

🎀 EXAMPLE 🎀

                # Restart all the nodes, 10% at a time
                oc adm restart-kubelet nodes --all --directive=RemoveKubeletKubeconfig

                # Restart all the nodes, 20 nodes at a time
                oc adm restart-kubelet nodes --all --parallelism=20 --directive=RemoveKubeletKubeconfig

                # Restart all the nodes, 15% at a time
                oc adm restart-kubelet nodes --all --parallelism=15% --directive=RemoveKubeletKubeconfig

                # Restart all the masters at the same time
                oc adm restart-kubelet nodes -l node-role.kubernetes.io/master --parallelism=100% --directive=RemoveKubeletKubeconfig
