# Redmine

[Redmine](http://www.redmine.org) is a free and open source, web-based project management and issue tracking tool.

## TL;DR;

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

## Introduction

This chart bootstraps a [Redmine](https://github.com/bitnami/bitnami-docker-redmine) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

It also packages the [Bitnami MariaDB chart](https://github.com/kubernetes/charts/tree/master/bitnami/mariadb) and the [PostgreSQL chart](https://github.com/kubernetes/charts/tree/master/bitnami/postgresql) which are required for bootstrapping a MariaDB/PostgreSQL deployment for the database requirements of the Redmine application.

Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This chart has been tested to work with NGINX Ingress, cert-manager, fluentd and Prometheus on top of the [BKPR](https://kubeprod.io/).

## Prerequisites

- Kubernetes 1.12+
- Helm 2.11+ or Helm 3.0-beta3+
- 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`:

```bash
$ helm install my-release bitnami/redmine
```

The command deploys Redmine 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:

```bash
$ helm delete my-release
```

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

## Using PostgreSQL instead of MariaDB

This chart includes the option to use a PostgreSQL database for Redmine instead of MariaDB. To use this, set the `databaseType` parameter to `postgresql`:

```
helm install my-release bitnami/redmine --set databaseType=postgresql
```

## Parameters

The following table lists the configurable parameters of the Redmine chart and their default values.

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

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

```bash
$ helm install my-release \
  --set redmineUsername=admin,redminePassword=password,mariadb.mariadbRootPassword=secretpassword \
    bitnami/redmine
```

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

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

```bash
$ helm install my-release -f values.yaml bitnami/redmine
```

> **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.

### Replicas

Redmine writes uploaded files to a persistent volume. By default that volume cannot be shared between pods (RWO). In such a configuration the `replicas` option must be set to `1`. If the persistent volume supports more than one writer (RWX), ie NFS, `replicas` can be greater than `1`.

## Persistence

The [Bitnami Redmine](https://github.com/bitnami/bitnami-docker-redmine) image stores the Redmine data and configurations at the `/bitnami/redmine` 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. The volume is created using dynamic volume provisioning. Clusters configured with NFS mounts require manually managed volumes and claims.

See the [Parameters](#parameters) section to configure the PVC or to disable persistence.

### Existing PersistentVolumeClaims

The following example includes two PVCs, one for Redmine and another for MariaDB.

1. Create the PersistentVolume
1. Create the PersistentVolumeClaim
1. Create the directory, on a worker
1. Install the chart

```bash
$ helm install test --set persistence.existingClaim=PVC_REDMINE,mariadb.persistence.existingClaim=PVC_MARIADB bitnami/redmine
```

## Upgrading

### 14.0.0

- Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
- The `databaseType` parameters is no longer an object but a string. Allowed values are "mariadb" and "postgresql".
- Ingress configuration was standardized to simplify the way to configure the main host.
- Ports names were prefixed with the protocol to comply with Istio (see https://istio.io/docs/ops/deployment/requirements/).

### 13.0.0

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 https://github.com/helm/charts/pull/17309 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 5.0.0

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 5.0.0. The following example assumes that the release name is redmine:

```console
$ kubectl patch deployment redmine-redmine --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
# If using postgresql as database
$ kubectl patch deployment redmine-postgresql --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
# If using mariadb as database
$ kubectl delete statefulset redmine-mariadb --cascade=false
```
