Configure ECKedit
ECK can be configured using either command line flags or environment variables.
| Flag | Default | Description |

|
|
Duration representing the validity period of a generated CA certificate. |
|

|
|
Enables restrictions on cross-namespace resource association through RBAC. |
|
|
Verbosity level of logs. |

|

Maximum number of concurrent reconciles per controller (Elasticsearch, Kibana, APM Server). Affects the ability of the operator to process changes concurrently. |
|
|
Prometheus metrics port. Set to 0 to disable the metrics endpoint. |
|
|
Namespaces in which this operator should manage resources. Accepts multiple comma-separated values. Defaults to all namespaces if empty or unspecified. |

|
Path to the directory that contains the webhook server key and certificate. |
Unless noted otherwise, environment variables can be used instead of flags to configure the operator as well. Simply convert the flag name to upper case and replace any dashes (-) with underscores (_). For example, the log-verbosity flag can be set by an environment variable named LOG_VERBOSITY.
Duration values should be specified as numeric values suffixed by the time unit. For example, a duration of 10 hours should be specified as 10h. Acceptable time unit suffixes are:
| Suffix | Unit |
|---|---|
|
Milliseconds |
|
Seconds |
|
Minutes |
|
Hours |
Edit the elastic-operator StatefulSet to change any of the flag values. Enable ECK debug logs illustrates how to change the log level of the operator using this method.
