Configuration Changes

This guide covers how to apply configuration changes to a running UDS Core deployment by updating bundle overrides and redeploying.

Applying bundle override changes

When you need to change UDS Core configuration (such as adjusting resource limits, enabling features, or updating external endpoints), modify your bundle overrides and redeploy.

Update your bundle configuration

Modify the relevant values in your uds-bundle.yaml or uds-config.yaml:

packages:
  - name: core
    repository: registry.defenseunicorns.com/public/core
    ref: x.x.x-upstream
    overrides:
      component-name:
        chart-name:
          values:
            # Set the config path to the new value
            - path: config.path
              value: "new-value"

Rebuild and deploy the bundle
Terminal window
```
uds create <path-to-bundle-dir>
uds deploy uds-bundle-<name>-<arch>-<version>.tar.zst
```
Helm handles the rolling update for affected components. Pods that reference changed ConfigMaps or Secrets may need a restart. See Configure pod reload on config changes for automatic restart configuration.
Verify the change

Confirm the affected resources reflect the new configuration, for example:
Terminal window
```
uds zarf tools kubectl describe <resource> -n <namespace>
```
