## TL;DR

```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/ejbca
```

## Introduction

This chart bootstraps a [EJBCA](https://www.ejbca.org/) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

It also packages [Bitnami MariaDB](https://github.com/bitnami/charts/tree/master/bitnami/mariadb) as the required databases for the EJBCA application.

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

## Prerequisites

- Kubernetes 1.19+
- Helm 3.2.0+
- PV provisioner support in the underlying infrastructure

## Installing the Chart

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

```console
$ helm install my-release bitnami/ejbca
```

The command deploys EJBCA 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`

## Uninstalling the Chart

To uninstall/delete the `my-release` deployment:

```console
$ helm delete my-release
```

The command removes all the Kubernetes components associated with the chart and deletes the release.

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

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

```console
$ helm install my-release \
  --set ejbcaAdminUsername=admin,ejbcaAdminPassword=password,mariadb.auth.password=secretpassword \
    bitnami/discourse
```

The above command sets the EJBCA administrator account username and password to `admin` and `password` respectively. Additionally, it sets the MariaDB `bn_ejbca` user password to `secretpassword`.

> 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 bitnami/ejbca
```

> **Tip**: You can use the default [values.yaml](values.yaml)

## Configuration and installation details

### [Rolling vs Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)

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.

### Set up replication

By default, this chart only deploys a single pod running EJBCA. To increase the number of replicas, follow the steps below:

1. Create a conventional release with only one replica. This will be scaled later.
2. Wait for the release to complete and for EJBCA to be running. Verify access to the main page of the application.
3. Perform an upgrade specifying the number of replicas and the credentials that were previously used. Set the parameters `replicaCount`, `ejbcaAdminPassword` and `mariadb.auth.password` accordingly.

For example, for a release using `secretPassword` and `dbPassword` to scale up to a total of `2` replicas, the aforementioned parameters should hold these values `replicaCount=2`, `ejbcaAdminPassword=secretPassword`, `mariadb.auth.password=dbPassword`.

> **Tip**: You can modify the file [values.yaml](values.yaml)

If additional containers are needed in the same pod as EJBCA (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter. Similarly, you can add extra init containers using the `initContainers` parameter.

[Learn more about configuring and using sidecar and init containers](https://docs.bitnami.com/kubernetes/apps/ejbca/configuration/configure-sidecar-init-containers/).

### Use an external database

Sometimes, you may want to have EJBCA connect to an external database rather than a database within your cluster - for example, when using a managed database service, or when running a single database server for all your applications. To do this, set the `mariadb.enabled` parameter to `false` and specify the credentials for the external database using the `externalDatabase.*` parameters.

Refer to the [chart documentation on using an external database](https://docs.bitnami.com/kubernetes/apps/ejbca/configuration/use-external-database) for more details and an example.

### Set Pod affinity

This chart allows you to set custom Pod affinity using the `affinity` parameter. 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 of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/master/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

### Use a different EJBCA version

To modify the application version used in this chart, specify a different version of the image using the `image.tag` parameter and/or a different repository using the `image.repository` parameter. Refer to the [chart documentation for more information on these parameters and how to use them with images from a private registry](https://docs.bitnami.com/kubernetes/apps/ejbca/configuration/change-image-version/).

## Persistence

The [Bitnami EJBCA](https://github.com/bitnami/bitnami-docker-discourse) image stores the EJBCA data and configurations at the `/bitnami` path of the container.

Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube. See the [Parameters](#parameters) section to configure the PVC or to disable persistence.

## Upgrading

### To 5.0.0

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` was deprecated, we recommend using`service.ports.http` instead.
- `service.httpsPort` was deprecated, we recommend using`service.port.https` instead.
- `extraEnv` renamed as `extraEnvVars`
- `persistence.accessMode` has been deprecated, we recommend using `persistence.accessModes` instead.

Additionally, updates the MariaDB subchart to it newest major, 10.0.0, which contains similar changes.

### To 2.0.0

[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.

[Learn more about this change and related upgrade considerations](https://docs.bitnami.com/kubernetes/apps/ejbca/administration/upgrade-helm3/).

### To 1.0.0

MariaDB dependency version was bumped to a new major version that introduces several incompatilibites. Therefore, backwards compatibility is not guaranteed unless an external database is used. Check [MariaDB Upgrading Notes](https://github.com/bitnami/charts/tree/master/bitnami/mariadb#to-800) for more information.

To upgrade to `1.0.0`, you have two alternatives:

- Install a new EJBCA chart, and migrate your EJBCA following [the official documentation](https://doc.primekey.com/ejbca/ejbca-operations/ejbca-operations-guide/ca-operations-guide/ejbca-maintenance/backup-and-restore).
- Reuse the PVC used to hold the MariaDB data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is `ejbca`):

> NOTE: Please, create a backup of your database before running any of those actions. The steps below would be only valid if your application (e.g. any plugins or custom code) is compatible with MariaDB 10.5.x

Obtain the credentials and the name of the PVC used to hold the MariaDB data on your current release:

```console
export EJBCA_ADMIN_PASSWORD=$(kubectl get secret --namespace default ejbca -o jsonpath="{.data.ejbca-admin-password}" | base64 --decode)
export MARIADB_ROOT_PASSWORD=$(kubectl get secret --namespace default ejbca-mariadb -o jsonpath="{.data.mariadb-root-password}" | base64 --decode)
export MARIADB_PASSWORD=$(kubectl get secret --namespace default ejbca-mariadb -o jsonpath="{.data.mariadb-password}" | base64 --decode)
export MARIADB_PVC=$(kubectl get pvc -l app=mariadb,component=master,release=ejbca -o jsonpath="{.items[0].metadata.name}")
```

Upgrade your release (maintaining the version) disabling MariaDB and scaling EJBCA replicas to 0:

```console
$ helm upgrade ejbca bitnami/ejbca --set ejbcaAdminPassword=$EJBCA_ADMIN_PASSWORD --set replicaCount=0 --set mariadb.enabled=false --version 0.4.0
```

Finally, upgrade you release to 1.0.0 reusing the existing PVC, and enabling back MariaDB:

```console
$ helm upgrade ejbca bitnami/ejbca --set mariadb.primary.persistence.existingClaim=$MARIADB_PVC --set mariadb.auth.rootPassword=$MARIADB_ROOT_PASSWORD --set mariadb.auth.password=$MARIADB_PASSWORD --set ejbcaAdminPassword=$EJBCA_ADMIN_PASSWORD
```

You should see the lines below in MariaDB container logs:

```console
$ kubectl logs $(kubectl get pods -l app.kubernetes.io/instance=ejbca,app.kubernetes.io/name=mariadb,app.kubernetes.io/component=primary -o jsonpath="{.items[0].metadata.name}")
...
mariadb 12:13:24.98 INFO  ==> Using persisted data
mariadb 12:13:25.01 INFO  ==> Running mysql_upgrade
...
```
