Reloader can be configured to only watch namespaces labeled with one or more labels using the `--namespace-selector` parameter. Supported operators are `!, in, notin, ==, =, !=`, if no operator is found the 'exists' operator is inferred (i.e. key only). Additional examples of these selectors can be found in the [Kubernetes Docs](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors).

Reloader can be configured to ignore the resources `secrets` and `configmaps` by using the following parameters of `values.yaml` file:
| Parameter | Description | Type |
| ---------------- | -------------------------------------------------------------- | ------- |
| ignoreSecrets | To ignore secrets. Valid value are either `true` or `false` | boolean |

(e.g. If a configMap matches `resourceLabelSelector` but `namespaceSelector` does not match the namespace the configmap is in, it will be ignored).

**Note:** Reloading of OpenShift (DeploymentConfig) and/or Argo `Rollouts` has to be enabled explicitly because it might not be always possible to use it on a cluster with restricted permissions. This can be done by changing the following parameters:

**isOpenShift** Recent versions of OpenShift (tested on 4.13.3) require the specified user to be in an `uid` range which is dynamically assigned by the namespace. The solution is to unset the runAsUser variable via ``deployment.securityContext.runAsUser=null`` and let OpenShift assign it at install.

**reloadOnCreate** controls how Reloader handles secrets being added to the cache for the first time. If reloadOnCreate is set to true:
- Configmaps/secrets being added to the cache will cause Reloader to perform a rolling update of the associated workload.
- When applications are deployed for the first time, Reloader will perform a rolling update of the associated workload.
- If you are running Reloader in HA mode all workloads will have a rolling update performed when a new leader is elected.
If ReloadOnCreate is set to false:
If reloadOnCreate is set to false:
- Updates to configMaps/Secrets that occur while there is no leader will not be picked up by the new leader until a subsequent update of the configmap/secret occurs. In the worst case the window in which there can be no leader is 15s as this is the LeaseDuration.
**Note:** By default, **reloadOnCreate** and **syncAfterRestart** are both set to false. Both need to be enabled explicitly.
