# Advanced configuration

Tune pod security context and resource sizing for the Harness SMP Operator.

This topic covers the security context and resource sizing settings for the Harness SMP Operator. The installer applies a default value for each of them, and you override the defaults through the same `override.yaml` file or `clustermgr` flags you use to install.

***

### Configuration topics <a href="#configuration-topics" id="configuration-topics"></a>

Each topic lists the default values the installer applies and shows how to override them with either Helm or clustermgr.

* [Pod security context](/self-managed-enterprise-edition/use-self-managed-enterprise-edition/smp-installationupgrade/operator-installation/advanced-configuration/pod-security-context.md): Change the user and group IDs the containers run as, if the defaults do not meet your organization's security policies.
* [Resource sizing](/self-managed-enterprise-edition/use-self-managed-enterprise-edition/smp-installationupgrade/operator-installation/advanced-configuration/resource-sizing.md): Review the default CPU and memory requests and limits, and resize them if there is a recommendation from the Harness SMP team.
