# Configure ECK
This section covers ECK configuration mechanisms and use cases, starting with the basic setup of the operator using the provided `ConfigMap` and extending to more advanced configuration scenarios that require detailed procedures.
<tip>
  This content focuses on ECK operator configuration. For details on available features and how to configure your Elasticsearch and Kibana deployments, refer to [Configure deployments](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-on-k8s/configure-deployments).
</tip>

The following guides cover common ECK configuration tasks:
- [Apply ECK configuration settings](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-on-k8s/configure-eck): Apply configuration changes, such the CA certificate validity period, the namespaces where the operator is allowed to work, or the log verbosity level for ECK.
- [Configure the validating webhook](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-on-k8s/configure-validating-webhook): Enable or disable the webhook, and configure multiple SSL certificate generation options.
- [Restrict cross-namespace resource associations](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-on-k8s/restrict-cross-namespace-resource-associations): Configure access control rules for cross-namespace associations. This functionality is disabled by default.
- [Create custom images](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-on-k8s/create-custom-images): Use your own images with Elasticsearch plugins already installed rather than installing them through init containers.
- [Service meshes](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-on-k8s/service-meshes): Connect ECK and managed Elastic Stack applications to some of the most popular [service mesh](https://www.cncf.io/blog/2017/04/26/service-mesh-critical-component-cloud-native-stack/) implementations in the Kubernetes ecosystem.
- [Network policies](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/security/k8s-network-policies): Use [Kubernetes network policies](https://kubernetes.io/docs/concepts/services-networking/network-policies/) to isolate pods by restricting incoming and outgoing network connections to a trusted set of sources and destinations.
- [Webhook namespace selectors](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-on-k8s/webhook-namespace-selectors): Restrict the namespaces that the validation webhook applies to, allowing multiple operators to coexist efficiently in the same cluster.
