🌸 KUBERNETES — kube-scheduler 💅

okay bestie, welcome to the group chat that is your terminal. this is part of the kubernetes manual family, and today we're hyperfixating on kube-scheduler. the original page was written by Eric Paris, Jan 2015 — an actual icon, we respect the elder. 🫶

✨ NAME ✨

kube-scheduler — that's it, that's the name. no long description here, the NAME section is lowkey mysterious and we love that for it. 💜

✨ SYNOPSIS ✨

kube-scheduler [OPTIONS]

✨ DESCRIPTION ✨

so like. the Kubernetes scheduler is a control plane process which assigns Pods to Nodes. that's the whole job, and it is so main character. ✨

the scheduler determines which Nodes are valid placements for each Pod in the scheduling queue according to constraints and available resources. then — plot twist — the scheduler ranks each valid Node and binds the Pod to a suitable Node. it's giving matchmaker, honestly. 💖

Multiple different schedulers may be used within a cluster; kube-scheduler is the reference implementation. yes, the blueprint, the blueprint-iest. 👑

See scheduling ⟨https://kubernetes.io/docs/concepts/scheduling-eviction/⟩ for more information about scheduling and the kube-scheduler component. go read it bestie, iykyk.

✨ OPTIONS ✨

there are a LOT of these, so grab a strawberry 🍓 and settle in. every single one is here, no skips.

  • --allow-metric-labels=[] — The map from metric-label to value allow-list of this label. The key's format is ,. The value's format is ,... e.g. metric1,label1='v1,v2,v3', metric1,label2='v1,v2,v3' metric2,label1='v1,v2,v3'.
  • --allow-metric-labels-manifest="" — The path to the manifest file that contains the allow-list mapping. The format of the file is the same as the flag --allow-metric-labels, i.e.
allowListMapping:
  "metric1,label1": "value11,value12"
  "metric2,label2": ""

Note that the flag --allow-metric-labels will override the manifest file.

  • --authentication-kubeconfig="" — kubeconfig file pointing at the 'core' kubernetes server with enough rights to create tokenreviews.authentication.k8s.io. This is optional. If empty, all token requests are considered to be anonymous and no client CA is looked up in the cluster.
  • --authentication-skip-lookup=false — If false, the authentication-kubeconfig will be used to lookup missing authentication configuration from the cluster.
  • --authentication-token-webhook-cache-ttl=10s — The duration to cache responses from the webhook token authenticator.
  • --authentication-tolerate-lookup-failure=true — If true, failures to look up missing authentication configuration from the cluster are not considered fatal. Note that this can result in authentication that treats all requests as anonymous. 🙈
  • --authorization-always-allow-paths=[/healthz,/readyz,/livez] — A list of HTTP paths to skip during authorization, i.e. these are authorized without contacting the 'core' kubernetes server.
  • --authorization-kubeconfig="" — kubeconfig file pointing at the 'core' kubernetes server with enough rights to create subjectaccessreviews.authorization.k8s.io. This is optional. If empty, all requests not skipped by authorization are forbidden. 💀
  • --authorization-webhook-cache-authorized-ttl=10s — The duration to cache 'authorized' responses from the webhook authorizer.
  • --authorization-webhook-cache-unauthorized-ttl=10s — The duration to cache 'unauthorized' responses from the webhook authorizer.
  • --bind-address=0.0.0.0 — The IP address on which to listen for the --secure-port port. The associated interface(s) must be reachable by the rest of the cluster, and by CLI/web clients. If blank or an unspecified address (0.0.0.0 or ::), all interfaces and IP address families will be used.
  • --cert-dir="" — The directory where the TLS certs are located. If --tls-cert-file and --tls-private-key-file are provided, this flag will be ignored. (yeah, it gets benched. sorry girl. 🎀)
  • --client-ca-file="" — If set, any request presenting a client certificate signed by one of the authorities in the client-ca-file is authenticated with an identity corresponding to the CommonName of the client certificate.
  • --config="" — The path to the configuration file.
  • --contention-profiling=true — DEPRECATED: enable block profiling, if profiling is enabled. This parameter is ignored if a config file is specified in --config.
⚠️ bestie, that one is DEPRECATED. respect the warning label like it's a red flag on a crush. 🚩
  • --disable-http2-serving=false — If true, HTTP2 serving will be disabled [default=false]
  • --disabled-metrics=[] — This flag provides an escape hatch for misbehaving metrics. You must provide the fully qualified metric name in order to disable it. Disclaimer: disabling metrics is higher in precedence than showing hidden metrics.
  • --emulated-version=[] — The versions different components emulate their capabilities (APIs, features, ...) of. If set, the component will emulate the behavior of this version instead of the underlying binary version. Version format could only be major.minor, for example: '--emulated-version=wardle=1.2,kube=1.31'. Options are: kube=1.34..1.37 (default:1.37) If the component is not specified, defaults to "kube".

and that's the first chunk, bestie — more coming, don't go anywhere 💖

okay so bestie, this one is a BEAST and I need you to breathe with me before we start 💀

  • --feature-gates= — a comma-separated list of component:key=value pairs, and those pairs describe the feature gates for alpha and experimental features across different components. If you don't tell it which component, it just assumes kube, no drama. This flag can be repeatedly invoked — like, over and over, it does not care. For example:
--feature-gates 'wardle:featureA=true,wardle:featureB=false' --feature-gates 'kube:featureC=true'

  • -h, --help=false — the help for kube-scheduler, bestie. It's right there. 💖
  • --http2-max-streams-per-connection=0 — the cap the server hands to clients for how many streams can ride one HTTP/2 connection. Zero means "just use golang's default", so like, it's giving "let Go cook". 🍳
  • --kube-api-burst=100 — DEPRECATED, okay? It's the burst to use while talking with kubernetes apiserver. And here's the tea: this parameter is ignored if a config file is specified in --config. 💀
  • --kube-api-content-type="application/vnd.kubernetes.protobuf" — DEPRECATED: content type of requests sent to apiserver. Same deal, ignored if a config file is specified in --config. 🙈
  • --kube-api-qps=50 — DEPRECATED: the QPS to use while talking with kubernetes apiserver. Yep, you guessed it, ignored if a config file is specified in --config. 😭
  • --kubeconfig="" — DEPRECATED: path to kubeconfig file with authorization and master location information. And this parameter is ignored if a config file is specified in --config. Not me repeating myself, that's just what the page says. 💅
  • --leader-elect=true — start a leader election client and gain leadership before executing the main loop. Enable this when running replicated components for high availability, iykyk. 👑
  • --leader-elect-lease-duration=15s — the duration that non-leader candidates will wait after observing a leadership renewal until attempting to acquire leadership of a led but unrenewed leader slot. Basically it's the max time a leader can be stopped before someone else takes the crown. Only applicable if leader election is enabled. ⏳
  • --leader-elect-renew-deadline=10s — the interval between attempts by the acting master to renew a leadership slot before it stops leading. This must be less than the lease duration. Only applicable if leader election is enabled. 🚨
  • --leader-elect-resource-lock="leases" — the type of resource object used for locking during leader election. Supported options are 'leases'. That's it, that's the list. ✨
  • --leader-elect-resource-name="kube-scheduler" — the name of the resource object used for locking during leader election. 🏷️
  • --leader-elect-resource-namespace="kube-system" — the namespace of the resource object used for locking during leader election. 🌌
  • --leader-elect-retry-period=2s — the duration the clients should wait between attempting acquisition and renewal of a leadership. Only applicable if leader election is enabled. 🔁
  • --log-flush-frequency=5s — maximum number of seconds between log flushes. Keep the logs flowing, periodt. 🌊
  • --log-text-info-buffer-size=0 — [Alpha] in text format with split output streams, the info messages can be buffered for a while to increase performance. The default value of zero bytes disables buffering. The size can be specified as number of bytes (512), multiples of 1000 (1K), multiples of 1024 (2Ki), or powers of those (3M, 4G, 5Mi, 6Gi). Enable the LoggingAlphaOptions feature gate to use this. 🧮
  • --log-text-split-stream=false — [Alpha] in text format, write error messages to stderr and info messages to stdout. The default is to write a single stream to stdout. Enable the LoggingAlphaOptions feature gate to use this. 🎀
  • --logging-format="text" — sets the log format. Permitted formats: "text". That's the whole menu, bestie. 🍽️
  • --master="" — the address of the Kubernetes API server (overrides any value in kubeconfig). 🎯
  • --min-compatibility-version=[] — the min version of control plane components the server should be compatible with. Must be less or equal to the emulated-version. Version format could only be major.minor, for example: '--min-compatibility-version=wardle=1.2,kube=1.31'. Options are: kube=1.34..1.37(default:1.36). If the component is not specified, defaults to "kube". 🌈
  • --permit-address-sharing=false — if true, SO_REUSEADDR will be used when binding the port. This allows binding to wildcard IPs like 0.0.0.0 and specific IPs in parallel, and it avoids waiting for the kernel to release sockets in TIME_WAIT state. [default=false] 🦋
  • --permit-port-sharing=false — if true, SO_REUSEPORT will be used when binding the port, which allows more than one instance to bind on the same address and port. [default=false] 🌸
  • --pod-max-in-unschedulable-pods-duration=5m0s — DEPRECATED: the maximum time a pod can stay in unschedulablePods. If a pod stays in unschedulablePods for longer than this value, the pod will be moved from unschedulablePods to backoffQ or activeQ. This flag is deprecated and will be removed in a future version. 💀
  • --profiling=true — DEPRECATED: enable profiling via web interface host:port/debug/pprof/. This parameter is ignored if a config file is specified in --config. 📈
  • --requestheader-allowed-names=[] — list of client certificate common names to allow to provide usernames in headers specified by --requestheader-username-headers. If empty, any client certificate validated by the authorities in --requestheader-client-ca-file is allowed. 🪪
  • --requestheader-client-ca-file="" — root certificate bundle to use to verify client certificates on incoming requests before trusting usernames in headers specified by --requestheader-username-headers. WARNING: generally do not depend on authorization being already done for incoming requests. ⚠️
  • --requestheader-extra-headers-prefix=[x-remote-extra-] — list of request header prefixes to inspect. X-Remote-Extra- is suggested. 🔍
  • --requestheader-group-headers=[x-remote-group] — list of request headers to inspect for groups. X-Remote-Group is suggested. 👥
  • --requestheader-uid-headers=[] — list of request headers to inspect for UIDs. X-Remote-Uid is suggested. Requires the RemoteRequestHeaderUID feature to be enabled. 🆔
  • --requestheader-username-headers=[x-remote-user] — list of request headers to inspect for usernames. X-Remote-User is common. 🙋
  • --secure-port=10259 — the port on which to serve HTTPS with authentication and authorization. If 0, don't serve HTTPS at all. 🔒
  • --show-hidden-metrics-for-version="" — the previous version for which you want to show hidden metrics. Only the previous minor version is meaningful, other values will not be allowed. The format is ., e.g.: '1.16'. The purpose of this format is make sure you have the opportunity to notice if the next release hides additional metrics, rather than being surprised when they are permanently removed in the release after that. Vibe check your metrics before they ghost you forever. 👻
  • --tls-cert-file="" — file containing the default x509 Certificate for HTTPS. (CA cert, if any, concatenated after server cert). If HTTPS serving is enabled, and --tls-cert-file and --tls-private-key-file are not provided, a self-signed certificate and key are generated for the public address and saved to the directory specified by --cert-dir. 🔐
  • --tls-cipher-suites=[] — comma-separated list of cipher suites for the server. If omitted, the default Go cipher suites will be used. Preferred values: TLS_AES_128_GCM_SHA256, TLS_AES_256_GCM_SHA384, TLS_CHACHA20_POLY1305_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305, TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256. Insecure values: TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_RC4_128_SHA, TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_RC4_128_SHA, TLS_RSA_WITH_3DES_EDE_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA256, TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_256_GCM_SHA384, TLS_RSA_WITH_RC4_128_SHA. 🛡️
  • --tls-curve-preferences=[] — comma-separated list of numeric Go crypto/tls CurveID values, as the allowed key exchange mechanisms for the server. The supported values depend on the Go version used. See https://pkg.go.dev/crypto/tls#CurveID for values supported for each Go version. The order of the list is ignored, and key exchange mechanisms are chosen by Go from this list using an internal preference order. If omitted, the default Go curves will be used. 🌀
  • --tls-min-version="" — minimum TLS version supported. Possible values: VersionTLS10, VersionTLS11, VersionTLS12, VersionTLS13. 🪜
  • --tls-private-key-file="" — file containing the default x509 private key matching --tls-cert-file. 🗝️
  • --tls-sni-cert-key=[] — a pair of x509 certificate and private key file paths, optionally suffixed with a list of domain patterns which are fully qualified domain names, possibly with prefixed wildcard segments. The domain patterns also allow IP addresses, but IPs should only be used if the apiserver has visibility to the IP address requested by a client. If no domain patterns are provided, the names of the certificate are extracted. Non-wildcard matches trump over wildcard matches, explicit domain patterns trump over extracted names. For multiple key/certificate pairs, use the --tls-sni-cert-key multiple times. Examples: "example.crt,example.key" or "foo.crt,foo.key:*.foo.com,foo.com". 👑
  • -v, --v=0 — number for the log level verbosity. Crank it up if you want the whole story. 🗣️
  • --version=false — --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version. 🏷️
  • --vmodule= — comma-separated list of pattern=N settings for file-filtered logging (only works for text log format). 🎛️
  • --write-config-to="" — if set, write the configuration values to this file and exit. 💾
