Configuring ECK

You can use several options to configure ECK. Unless otherwise noted, these options can be set as environment variables or command line flags.

Flag	Type	Default	Description
`log-verbosity`	int	0	Verbosity level of logs. -2=Error, -1=Warn, 0=Info, >0=Debug
`enable-debug-logs`	bool	false	Enables debug logs. Equivalent to `log-verbosity=1`
`metrics-port`	int	0	Port to use for exposing metrics in the Prometheus format. Set 0 to disable
`operator-roles`	[]string	all	Roles this operator should assume. Valid values are namespace, global, webhook or all. Accepts multiple comma separated values. See Namespace and role configuration for more information
`namespace`	string	`""`	Namespace in which this operator should manage resources. Defaults to all namespaces. See Namespace and role configuration for more information
`ca-cert-validity`	duration (string)	1y	Duration representing how long before a newly created CA cert expires
`ca-cert-rotate-before`	duration (string)	1d	Duration representing how long before expiration CA certificates should be reissued
`cert-validity`	duration (string)	1y	Duration representing how long before a newly created TLS certificate expires
`cert-rotate-before`	duration (string)	1d	Duration representing how long before expiration TLS certificates should be reissued
`auto-install-webhooks`	bool	true	Enables automatic webhook installation
`operator-namespace`	string	`""`	K8s namespace the operator runs in
`webhook-secret`	string	`""`	K8s secret name mounted into /tmp/cert to be used for webhook certificates
`webhook-pods-label`	string	`""`	K8s label to select pods running the operator
`development`	bool	false	Enable developmenet mode. Only available as a CLI flag, not an environment variable
`debug-http-listen`	string	localhost:6060	Listen address for the debug HTTP server. Only available in development mode
`auto-port-forward`	bool	false	Enables automatic port forwarding to allow running the operator outside the cluster. For dev use only as it exposes k8s resources on ephemeral ports to localhost

Many of these should not need to be modified, but if necessary you can modify the operator YAML. For instance, to enable DEBUG level logs on the operator, restart it with the flag --enable-debug-logs=true like so:

kubectl edit statefulset.apps -n elastic-system elastic-operator

and change the following lines from:

  spec:
    containers:
    - args:
      - manager
      - --operator-roles
      - all
      - --enable-debug-logs=false

to:

  spec:
    containers:
    - args:
      - manager
      - --operator-roles
      - all
      - --enable-debug-logs=true
