Alternatively if you have configured helm on your cluster, you can add Reloader to helm from our public chart repository and deploy it via helm using below-mentioned commands. Follow [this](docs/Helm2-to-Helm3.md) guide, in case you have trouble migrating Reloader from Helm2 to Helm3.
#### Installation
```bash
helm repo add stakater https://stakater.github.io/stakater-charts
helm repo update
helm install stakater/reloader # For helm3 add --generate-name flag or set the release name
helm install {{RELEASE_NAME}} stakater/reloader -n {{NAMESPACE}} --set reloader.watchGlobally=false # By default, Reloader watches in all namespaces. To watch in single namespace, set watchGlobally=false
helm install stakater/reloader --set reloader.watchGlobally=false --namespace test --generate-name # Install Reloader in `test` namespace which will only watch `Deployments`, `Daemonsets` `Statefulsets` and `Rollouts` in `test` namespace.
```
**Note:** By default Reloader watches in all namespaces. To watch in single namespace, please run following command. It will install Reloader in `test` namespace which will only watch `Deployments`, `Daemonsets` `Statefulsets` and `Rollouts` in `test` namespace.
#### Uninstalling
```bash
helm install stakater/reloader --set reloader.watchGlobally=false --namespace test # For helm3 add --generate-name flag or set the release name
helm uninstall {{RELEASE_NAME}} -n {{NAMESPACE}}
```

| ignoreConfigMaps | To ignore configMaps. Valid value are either `true` or `false` | boolean |
#### Global Parameters
**Note:** At one time only one of these resource can be ignored, trying to do it will cause error in helm template compilation.
| Parameter | Description | Type | Default |
|---------------------------|-----------------------------------------------------------------|-------|---------|
| `global.imagePullSecrets` | Reference to one or more secrets to be used when pulling images | array | `[]` |

**Note:** Both `namespaceSelector` & `resourceLabelSelector` can be used together. If they are then both conditions must be met for the configmap or secret to be eligible to trigger reload events. (e.g. If a configMap matches `resourceLabelSelector` but `namespaceSelector` does not match the namespace the configmap is in, it will be ignored).
#### Deployment Reloader Parameters
You can also set the log format of Reloader to JSON by setting `logFormat` to `json` in `values.yaml` and apply the chart.
| Parameter | Description | Type | Default |
|-------------------------------------------------|-----------------------------------------------------------------------------------------|--------|-------------------|
| `reloader.deployment.replicas` | Number of replicas, if you wish to run multiple replicas set `reloader.enableHA = true` | int | 1 |

You can enable to scrape Reloader's Prometheus metrics by setting `serviceMonitor.enabled` or `podMonitor.enabled` to `true` in `values.yaml` file. Service monitor will be removed in future releases of Reloader in favour of Pod monitor.
#### Other Reloader Parameters
**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:
| Parameter | Description | Type | Default |
|----------------------------------------|-----------------------------------------------------------------|---------|---------|
| `reloader.service` | | map | `{}` |
| `reloader.rbac.enabled` | Specifies whether a role based access control should be created | boolean | `true` |

| `reloader.webhookUrl` | Add webhook to Reloader | string | `""` |
| Parameter | Description | Type |
|------------------|------------------------------------------------------------------------------------------------------------------------------------------| ------- |
| isOpenshift | Enable OpenShift DeploymentConfigs. Valid value are either `true` or `false` | boolean |
| isArgoRollouts | Enable Argo `Rollouts`. Valid value are either `true` or `false` | boolean |
| reloadOnCreate | Enable reload on create events. Valid value are either `true` or `false` | boolean |
| syncAfterRestart | Enable sync after Reloader restarts for **Add** events, works only when reloadOnCreate is `true`. Valid value are either `true` or `false` | boolean |
#### Additional Remarks
**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** 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:
- 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.
- Both `namespaceSelector` & `resourceLabelSelector` can be used together. If they are then both conditions must be met for the configmap or secret to be eligible to trigger reload events. (e.g. If a configMap matches `resourceLabelSelector` but `namespaceSelector` does not match the namespace the configmap is in, it will be ignored).
- At one time only one of the resources `ignoreConfigMaps` or `ignoreSecrets` can be ignored, trying to do both will cause error in helm template compilation
- 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
- `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:
1. Configmaps/secrets being added to the cache will cause Reloader to perform a rolling update of the associated workload
1. When applications are deployed for the first time, Reloader will perform a rolling update of the associated workload
1. If you are running Reloader in HA mode all workloads will have a rolling update performed when a new leader is elected
- `serviceMonitor` will be removed in future releases of Reloader in favour of Pod monitor
- If `reloadOnCreate` is set to false:
1. 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
1. In the worst case the window in which there can be no leader is 15s as this is the LeaseDuration
- By default, `reloadOnCreate` and `syncAfterRestart` are both set to false. Both need to be enabled explicitly
