Controller Options

The external-secrets binary includes three components: core controller, certcontroller and webook.

Core Controller Flags

The core controller is invoked without a subcommand and can be configured with the following flags:

Name Type Default Descripton
--client-burst int uses rest client default (10) Maximum Burst allowed to be passed to rest.Client
--client-qps float32 uses rest client default (5) QPS configuration to be passed to rest.Client
--concurrent int 1 The number of concurrent ExternalSecret reconciles.
--controller-class string default The controller is instantiated with a specific controller name and filters ES based on this property
--enable-cluster-external-secret-reconciler boolean true Enables the cluster external secret reconciler.
--enable-cluster-store-reconciler boolean true Enables the cluster store reconciler.
--enable-secrets-caching boolean false Enables the secrets caching for external-secrets pod.
--enable-configmaps-caching boolean false Enables the ConfigMap caching for external-secrets pod.
--enable-flood-gate boolean true Enable flood gate. External secret will be reconciled only if the ClusterStore or Store have an healthy or unknown state.
--enable-leader-election boolean false Enable leader election for controller manager. Enabling this will ensure there is only one active controller manager.
--experimental-enable-aws-session-cache boolean false Enable experimental AWS session cache. External secret will reuse the AWS session without creating a new one on each request.
--help help for external-secrets
--loglevel string info loglevel to use, one of: debug, info, warn, error, dpanic, panic, fatal
--metrics-addr string :8080 The address the metric endpoint binds to.
--namespace string - watch external secrets scoped in the provided namespace only. ClusterSecretStore can be used but only work if it doesn't reference resources from other namespaces
--store-requeue-interval duration 5m0s Default Time duration between reconciling (Cluster)SecretStores

Cert Controller Flags

Name Type Default Descripton
--crd-requeue-interval duration 5m0s Time duration between reconciling CRDs for new certs
--enable-leader-election boolean false Enable leader election for controller manager. Enabling this will ensure there is only one active controller manager.
--healthz-addr string :8081 The address the health endpoint binds to.
--help help for certcontroller
--loglevel string info loglevel to use, one of: debug, info, warn, error, dpanic, panic, fatal
--metrics-addr string :8080 The address the metric endpoint binds to.
--secret-name string external-secrets-webhook Secret to store certs for webhook
--secret-namespace string default namespace of the secret to store certs
--service-name string external-secrets-webhook Webhook service name
--service-namespace string default Webhook service namespace

Webhook Flags

Name Type Default Descripton
--cert-dir string /tmp/k8s-webhook-server/serving-certs path to check for certs
--check-interval duration 5m0s certificate check interval
--dns-name string localhost DNS name to validate certificates with
--healthz-addr string :8081 The address the health endpoint binds to.
--help help for webhook
--loglevel string info loglevel to use, one of: debug, info, warn, error, dpanic, panic, fatal
--lookahead-interval duration 2160h0m0s (90d) certificate check interval
--metrics-addr string :8080 The address the metric endpoint binds to.
--port number 10250 Port number that the webhook server will serve.
--tls-ciphers string comma separated list of tls ciphers allowed. This does not apply to TLS 1.3 as the ciphers are selected automatically. The order of this list does not give preference to the ciphers, the ordering is done automatically. Full lists of available ciphers can be found at https://pkg.go.dev/crypto/tls#pkg-constants. E.g. 'TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256'
--tls-min-version string 1.2 minimum version of TLS supported.
