kube-state-metrics can be configured through command line arguments.
Those arguments can be passed during startup when running locally:
kube-state-metrics --telemetry-port=8081 --kubeconfig=<KUBE-CONFIG> --apiserver=<APISERVER> ...
Or configured in the args section of your deployment configuration in a Kubernetes / Openshift context:
spec:
template:
spec:
containers:
- args:
- '--telemetry-port=8081'
- '--kubeconfig=<KUBE-CONFIG>'
- '--apiserver=<APISERVER>'$ kube-state-metrics -h
kube-state-metrics is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects.
Usage:
kube-state-metrics [flags]
kube-state-metrics [command]
Available Commands:
completion Generate completion script for kube-state-metrics.
help Help about any command
version Print version information.
Flags:
--add_dir_header If true, adds the file directory to the header of the log messages
--alsologtostderr log to standard error as well as files (no effect when -logtostderr=true)
--apiserver string The URL of the apiserver to use as a master
--config string Path to the kube-state-metrics options config file
--custom-resource-state-config string Inline Custom Resource State Metrics config YAML (experimental)
--custom-resource-state-config-file string Path to a Custom Resource State Metrics config file (experimental)
--custom-resource-state-only Only provide Custom Resource State metrics (experimental)
--enable-gzip-encoding Gzip responses when requested by clients via 'Accept-Encoding: gzip' header.
-h, --help Print Help text
--host string Host to expose metrics on. (default "::")
--kubeconfig string Absolute path to the kubeconfig file
--log_backtrace_at traceLocation when logging hits line file:N, emit a stack trace (default :0)
--log_dir string If non-empty, write log files in this directory (no effect when -logtostderr=true)
--log_file string If non-empty, use this log file (no effect when -logtostderr=true)
--log_file_max_size uint Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
--logtostderr log to standard error instead of files (default true)
--metric-allowlist string Comma-separated list of metrics to be exposed. This list comprises of exact metric names and/or regex patterns. The allowlist and denylist are mutually exclusive.
--metric-annotations-allowlist string Comma-separated list of Kubernetes annotations keys that will be used in the resource' labels metric. By default the metric contains only name and namespace labels. To include additional annotations provide a list of resource names in their plural form and Kubernetes annotation keys you would like to allow for them (Example: '=namespaces=[kubernetes.io/team,...],pods=[kubernetes.io/team],...)'. A single '*' can be provided per resource instead to allow any annotations, but that has severe performance implications (Example: '=pods=[*]').
--metric-denylist string Comma-separated list of metrics not to be enabled. This list comprises of exact metric names and/or regex patterns. The allowlist and denylist are mutually exclusive.
--metric-labels-allowlist string Comma-separated list of additional Kubernetes label keys that will be used in the resource' labels metric. By default the metric contains only name and namespace labels. To include additional labels provide a list of resource names in their plural form and Kubernetes label keys you would like to allow for them (Example: '=namespaces=[k8s-label-1,k8s-label-n,...],pods=[app],...)'. A single '*' can be provided per resource instead to allow any labels, but that has severe performance implications (Example: '=pods=[*]'). Additionally, an asterisk (*) can be provided as a key, which will resolve to all resources, i.e., assuming '--resources=deployments,pods', '=*=[*]' will resolve to '=deployments=[*],pods=[*]'.
--metric-opt-in-list string Comma-separated list of metrics which are opt-in and not enabled by default. This is in addition to the metric allow- and denylists
--namespaces string Comma-separated list of namespaces to be enabled. Defaults to ""
--namespaces-denylist string Comma-separated list of namespaces not to be enabled. If namespaces and namespaces-denylist are both set, only namespaces that are excluded in namespaces-denylist will be used.
--node string Name of the node that contains the kube-state-metrics pod. Most likely it should be passed via the downward API. This is used for daemonset sharding. Only available for resources (pod metrics) that support spec.nodeName fieldSelector. This is experimental.
--one_output If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
--pod string Name of the pod that contains the kube-state-metrics container. When set, it is expected that --pod and --pod-namespace are both set. Most likely this should be passed via the downward API. This is used for auto-detecting sharding. If set, this has preference over statically configured sharding. This is experimental, it may be removed without notice.
--pod-namespace string Name of the namespace of the pod specified by --pod. When set, it is expected that --pod and --pod-namespace are both set. Most likely this should be passed via the downward API. This is used for auto-detecting sharding. If set, this has preference over statically configured sharding. This is experimental, it may be removed without notice.
--port int Port to expose metrics on. (default 8080)
--resources string Comma-separated list of Resources to be enabled. Defaults to "certificatesigningrequests,configmaps,cronjobs,daemonsets,deployments,endpoints,horizontalpodautoscalers,ingresses,jobs,leases,limitranges,mutatingwebhookconfigurations,namespaces,networkpolicies,nodes,persistentvolumeclaims,persistentvolumes,poddisruptionbudgets,pods,replicasets,replicationcontrollers,resourcequotas,secrets,services,statefulsets,storageclasses,validatingwebhookconfigurations,volumeattachments"
--shard int32 The instances shard nominal (zero indexed) within the total number of shards. (default 0)
--skip_headers If true, avoid header prefixes in the log messages
--skip_log_headers If true, avoid headers when opening log files (no effect when -logtostderr=true)
--stderrthreshold severity logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=false) (default 2)
--telemetry-host string Host to expose kube-state-metrics self metrics on. (default "::")
--telemetry-port int Port to expose kube-state-metrics self metrics on. (default 8081)
--tls-config string Path to the TLS configuration file
--total-shards int The total number of shards. Sharding is disabled when total shards is set to 1. (default 1)
--use-apiserver-cache Sets resourceVersion=0 for ListWatch requests, using cached resources from the apiserver instead of an etcd quorum read.
-v, --v Level number for the log level verbosity
--vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging
