## Introduction

This chart bootstraps a [Jenkins](https://github.com/bitnami/containers/tree/main/bitnami/jenkins) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volumes for deployment scaling

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/jenkins
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

These commands deploy Jenkins on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Configuration and installation details

### Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcePreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).

### [Rolling vs Immutable tags](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Configure Ingress

This chart provides support for Ingress resources. If you have an ingress controller installed on your cluster, such as [nginx-ingress-controller](https://github.com/bitnami/charts/tree/main/bitnami/nginx-ingress-controller) or [contour](https://github.com/bitnami/charts/tree/main/bitnami/contour) you can utilize the ingress controller to serve your application.To enable Ingress integration, set `ingress.enabled` to `true`.

The most common scenario is to have one host name mapped to the deployment. In this case, the `ingress.hostname` property can be used to set the host name. The `ingress.tls` parameter can be used to add the TLS configuration for this host.

However, it is also possible to have more than one host. To facilitate this, the `ingress.extraHosts` parameter (if available) can be set with the host names specified as an array. The `ingress.extraTLS` parameter (if available) can also be used to add the TLS configuration for extra hosts.

> NOTE: For each host specified in the `ingress.extraHosts` parameter, it is necessary to set a name, path, and any annotations that the Ingress controller should know about. Not all annotations are supported by all Ingress controllers, but [this annotation reference document](https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/nginx-configuration/annotations.md) lists the annotations supported by many popular Ingress controllers.

Adding the TLS parameter (where available) will cause the chart to generate HTTPS URLs, and the  application will be available on port 443. The actual TLS secrets do not have to be generated by this chart. However, if TLS is enabled, the Ingress record will not work until the TLS secret exists.

[Learn more about Ingress controllers](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/).

### Configure TLS Secrets for use with Ingress

This chart facilitates the creation of TLS secrets for use with the Ingress controller (although this is not mandatory). There are several common use cases:

- Generate certificate secrets based on chart parameters.
- Enable externally generated certificates.
- Manage application certificates via an external service (like [cert-manager](https://github.com/jetstack/cert-manager/)).
- Create self-signed certificates within the chart (if supported).

In the first two cases, a certificate and a key are needed. Files are expected in `.pem` format.

Here is an example of a certificate file:

> NOTE: There may be more than one certificate if there is a certificate chain.

```text
-----BEGIN CERTIFICATE-----
MIID6TCCAtGgAwIBAgIJAIaCwivkeB5EMA0GCSqGSIb3DQEBCwUAMFYxCzAJBgNV
...
jScrvkiBO65F46KioCL9h5tDvomdU1aqpI/CBzhvZn1c0ZTf87tGQR8NK7v7
-----END CERTIFICATE-----
```

Here is an example of a certificate key:

```text
-----BEGIN RSA PRIVATE KEY-----
MIIEogIBAAKCAQEAvLYcyu8f3skuRyUgeeNpeDvYBCDcgq+LsWap6zbX5f8oLqp4
...
wrj2wDbCDCFmfqnSJ+dKI3vFLlEz44sAV8jX/kd4Y6ZTQhlLbYc=
-----END RSA PRIVATE KEY-----
```

- If using Helm to manage the certificates based on the parameters, copy these values into the `certificate` and `key` values for a given `*.ingress.secrets` entry.
- If managing TLS secrets separately, it is necessary to create a TLS secret with name `INGRESS_HOSTNAME-tls` (where INGRESS_HOSTNAME is a placeholder to be replaced with the hostname you set using the `*.ingress.hostname` parameter).
- If your cluster has a [cert-manager](https://github.com/jetstack/cert-manager) add-on to automate the management and issuance of TLS certificates, add to `*.ingress.annotations` the [corresponding ones](https://cert-manager.io/docs/usage/ingress/#supported-annotations) for cert-manager.
- If using self-signed certificates created by Helm, set both `*.ingress.tls` and `*.ingress.selfSigned` to `true`.

### Configure extra environment variables

To add extra environment variables (useful for advanced operations like custom init scripts), use the `extraEnvVars` property.

```yaml
extraEnvVars:
  - name: LOG_LEVEL
    value: DEBUG
```

Alternatively, use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` values.

### Configure Sidecars and Init Containers

If additional containers are needed in the same pod as Jenkins (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter.

```yaml
sidecars:
- name: your-image-name
  image: your-image
  imagePullPolicy: Always
  ports:
  - name: portname
    containerPort: 1234
```

If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter (where available), as shown in the example below:

```yaml
service:
  extraPorts:
  - name: extraPort
    port: 11311
    targetPort: 11311
```

> NOTE: This Helm chart already includes sidecar containers for the Prometheus exporters (where applicable). These can be activated by adding the `--enable-metrics=true` parameter at deployment time. The `sidecars` parameter should therefore only be used for any extra sidecar containers.

If additional init containers are needed in the same pod, they can be defined using the `initContainers` parameter. Here is an example:

```yaml
initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234
```

Learn more about [sidecar containers](https://kubernetes.io/docs/concepts/workloads/pods/) and [init containers](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/).

### Deploy extra resources

There are cases where you may want to deploy extra objects, such a ConfigMap containing your app's configuration or some extra deployment with a micro service used by your app. For covering this case, the chart allows adding the full specification of other objects using the `extraDeploy` parameter.

### Set Pod affinity

This chart allows you to set custom Pod affinity using the `XXX.affinity` parameter(s). Find more information about Pod affinity in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `XXX.podAffinityPreset`, `XXX.podAntiAffinityPreset`, or `XXX.nodeAffinityPreset` parameters.

## Persistence

The [Bitnami Jenkins](https://github.com/bitnami/containers/tree/main/bitnami/jenkins) image stores the Jenkins data and configurations at the `/bitnami/jenkins` path of the container. Persistent Volume Claims (PVCs) are used to keep the data across deployments.

If you encounter errors when working with persistent volumes, refer to our [troubleshooting guide for persistent volumes](https://docs.bitnami.com/kubernetes/faq/troubleshooting/troubleshooting-persistence-volumes/).

The above parameters map to the env variables defined in [bitnami/jenkins](https://github.com/bitnami/containers/tree/main/bitnami/jenkins). For more information please refer to the [bitnami/jenkins](https://github.com/bitnami/containers/tree/main/bitnami/jenkins) image documentation.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install my-release \
  --set jenkinsUser=admin \
  --set jenkinsPassword=password \
  oci://REGISTRY_NAME/REPOSITORY_NAME/jenkins
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The above command sets the Jenkins administrator account username and password to `admin` and `password` respectively.

> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/jenkins
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
> **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/jenkins/values.yaml)

## Upgrading

### To 13.0.0

This major bump changes the following security defaults:

- `runAsGroup` is changed from `0` to `1001`
- `readOnlyRootFilesystem` is set to `true`
- `resourcesPreset` is changed from `none` to the minimum size working in our test suites (NOTE: `resourcesPreset` is not meant for production usage, but `resources` adapted to your use case).
- `global.compatibility.openshift.adaptSecurityContext` is changed from `disabled` to `auto`.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

### To 11.0.0

This major release no longer contains preinstalled plugins. In case you want to install a plugin you can follow the [official documentation](https://www.jenkins.io/doc/book/managing/plugins/)

### To 10.0.0

This major release is no longer contains the metrics section because the container `bitnami/enkins-exporter` has been deprecated due to the upstream project is not maintained.

### To 9.0.0

This major release renames several values in this chart and adds missing features, in order to be inline with the rest of assets in the Bitnami charts repository.

Affected values:

- `service.port` renamed as `service.ports.http`.
- `service.httpsPort` renamed as `service.ports.https`.
- `serviceMonitor.additionalLabels` renamed as `serviceMonitor.labels`.

### To 8.0.0

Due to recent changes in the container image (see [Notable changes](https://github.com/bitnami/containers/tree/main/bitnami/jenkins#notable-changes)), the major version of the chart has been bumped preemptively.

Upgrading from version `7.x.x` should be possible following the workaround below (the following example assumes that the release name is `jenkins`):

- Create a backup of your Jenkins data (e.g. using Velero to backup your PV)
- Remove Jenkins deployment:

```console
export JENKINS_PASSWORD=$(kubectl get secret --namespace default jenkins -o jsonpath="{.data.jenkins-password}" | base64 -d)
kubectl delete deployments.apps jenkins
```

- Upgrade your release and delete data that should not be persisted anymore:

```console
helm upgrade jenkins oci://REGISTRY_NAME/REPOSITORY_NAME/jenkins --set jenkinsPassword=$JENKINS_PASSWORD --set jenkinsHome=/bitnami/jenkins/jenkins_home
kubectl exec -it $(kubectl get pod -l app.kubernetes.io/instance=jenkins,app.kubernetes.io/name=jenkins -o jsonpath="{.items[0].metadata.name}") -- find /bitnami/jenkins -mindepth 1 -maxdepth 1 -not -name jenkins_home -exec rm -rf {} \;
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

### To 7.0.0

Chart labels were adapted to follow the [Helm charts standard labels](https://helm.sh/docs/chart_best_practices/labels/#standard-labels).

Consequences:

- Backwards compatibility is not guaranteed. However, you can easily workaround this issue by removing Jenkins deployment before upgrading (the following example assumes that the release name is `jenkins`):

```console
export JENKINS_PASSWORD=$(kubectl get secret --namespace default jenkins -o jsonpath="{.data.jenkins-password}" | base64 -d)
kubectl delete deployments.apps jenkins
helm upgrade jenkins oci://REGISTRY_NAME/REPOSITORY_NAME/jenkins --set jenkinsPassword=$JENKINS_PASSWORD
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

### To 6.1.0

This version also introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/main/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.

### To 6.0.0

[On November 13, 2020, Helm v2 support formally ended](https://github.com/helm/charts#status-of-the-project). This major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

### To 5.0.0

The [Bitnami Jenkins](https://github.com/bitnami/containers/tree/main/bitnami/jenkins) image was migrated to a "non-root" user approach. Previously the container ran as the `root` user and the Jenkins service was started as the `jenkins` user. From now on, both the container and the Jenkins service run as user `jenkins` (`uid=1001`). You can revert this behavior by setting the parameters `securityContext.runAsUser`, and `securityContext.fsGroup` to `root`.
Ingress configuration was also adapted to follow the Helm charts best practices.

Consequences:

- No "privileged" actions are allowed anymore.
- Backwards compatibility is not guaranteed when persistence is enabled.

To upgrade to `5.0.0`, install a new Jenkins chart, and migrate your Jenkins data ensuring the `jenkins` user has the appropriate permissions.

### To 4.0.0

Helm performs a lookup for the object based on its group (apps), version (v1), and kind (Deployment). Also known as its GroupVersionKind, or GVK. Changing the GVK is considered a compatibility breaker from Kubernetes' point of view, so you cannot "upgrade" those objects to the new GVK in-place. Earlier versions of Helm 3 did not perform the lookup correctly which has since been fixed to match the spec.

In 4dfac075aacf74405e31ae5b27df4369e84eb0b0 the `apiVersion` of the deployment resources was updated to `apps/v1` in tune with the api's deprecated, resulting in compatibility breakage.

This major version signifies this change.

### To 1.0.0

Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
Use the workaround below to upgrade from versions previous to 1.0.0. The following example assumes that the release name is jenkins:

```console
kubectl patch deployment jenkins --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
```
