## ⚠️ Important Notice: Upcoming changes to the Bitnami Catalog

Beginning August 28th, 2025, Bitnami will evolve its public catalog to offer a curated set of hardened, security-focused images under the new [Bitnami Secure Images initiative](https://news.broadcom.com/app-dev/broadcom-introduces-bitnami-secure-images-for-production-ready-containerized-applications). As part of this transition:

- Granting community users access for the first time to security-optimized versions of popular container images.
- Bitnami will begin deprecating support for non-hardened, Debian-based software images in its free tier and will gradually remove non-latest tags from the public catalog. As a result, community users will have access to a reduced number of hardened images. These images are published only under the “latest” tag and are intended for development purposes
- Starting August 28th, over two weeks, all existing container images, including older or versioned tags (e.g., 2.50.0, 10.6), will be migrated from the public catalog (docker.io/bitnami) to the “Bitnami Legacy” repository (docker.io/bitnamilegacy), where they will no longer receive updates.
- For production workloads and long-term support, users are encouraged to adopt Bitnami Secure Images, which include hardened containers, smaller attack surfaces, CVE transparency (via VEX/KEV), SBOMs, and enterprise support.

These changes aim to improve the security posture of all Bitnami users by promoting best practices for software supply chain integrity and up-to-date deployments. For more details, visit the [Bitnami Secure Images announcement](https://github.com/bitnami/containers/issues/83267).

## Introduction

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

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

## 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/redmine
```

> 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 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`

## Configuration and installation details

### 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`:

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/redmine --set databaseType=postgresql
```

> 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`.

### Certificates

#### CA Certificates

Custom CA certificates not included in the base docker image can be added with
the following configuration. The secret must exist in the same namespace as the
deployment. Will load all certificates files it finds in the secret.

```yaml
certificates:
  customCAs:
    - secret: my-ca-1
    - secret: my-ca-2
```

##### CA Certificates Secret

Secret can be created with:

```console
kubectl create secret generic my-ca-1 --from-file my-ca-1.crt
```

#### TLS Certificate

A web server TLS Certificate can be injected into the container with the
following configuration. The certificate will be stored at the location
specified in the certificateLocation value.

```yaml
certificates:
  customCertificate:
    certificateSecret: my-secret
    certificateLocation: /ssl/server.pem
    keyLocation: /ssl/key.pem
    chainSecret:
      name: my-cert-chain
      key: chain.pem
```

##### TLS Certificate Secret

The certificate tls secret can be created with:

```console
kubectl create secret tls my-secret --cert tls.crt --key tls.key
```

The certificate chain is created with:

```console
kubectl create secret generic my-cert-chain --from-file chain.pem
```

### 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 `resourcesPreset` 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.

### Update credentials

Bitnami charts configure credentials at first boot. Any further change in the secrets or credentials require manual intervention. Follow these instructions:

- Update the user password following [the upstream documentation](https://www.redmine.org/guide)
- Update the password secret with the new values (replace the SECRET_NAME, PASSWORD and SMTP_PASSWORD placeholders)

```shell
kubectl create secret generic SECRET_NAME --from-literal=redmine-password=PASSWORD --from-literal=smtp-password=SMTP_PASSWORD --dry-run -o yaml | kubectl apply -f -
```

### 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`.

> **Important**: When running more than one instance of Redmine they must share the same `secret_key_base` to have sessions working acreoss all instances.
> This can be achieved by setting
>
> ```yaml
>   extraEnvVars:
>    - name: SECRET_KEY_BASE
>      value: someredminesecretkeybase
> ```

### Deploying to a sub-URI

(adapted from <https://github.com/bitnami/containers/tree/main/bitnami/redmine>)

On certain occasions, you may need that Redmine is available under a specific sub-URI path rather than the root. A common scenario to this problem may arise if you plan to set up your Redmine container behind a reverse proxy. To deploy your Redmine container using a certain sub-URI you just need to follow these steps:

#### Create a configmap containing an altered version of post-init.sh

```yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: redmine-init-configmap
  namespace: <same-namespace-as-the-chart>
  labels:
  ...
data:

  post-init.sh: |-
    #!/bin/bash

    # REPLACE WITH YOUR OWN SUB-URI
    SUB_URI_PATH='/redmine'

    #Config files where to apply changes
    config1=/opt/bitnami/redmine/config.ru
    config2=/opt/bitnami/redmine/config/environment.rb

    sed -i '$ d' ${config1}
    echo 'map ActionController::Base.config.try(:relative_url_root) || "/" do' >> ${config1}
    echo 'run Rails.application' >> ${config1}
    echo 'end' >> ${config1}
    echo 'Redmine::Utils::relative_url_root = "'${SUB_URI_PATH}'"' >> ${config2}

    SUB_URI_PATH=$(echo ${SUB_URI_PATH} | sed -e 's|/|\\/|g')
    sed -i -e "s/\(relative_url_root\ \=\ \"\).*\(\"\)/\1${SUB_URI_PATH}\2/" ${config2}
```

#### Add this confimap as a volume/volume mount in the chart values

```yaml
## Extra volumes to add to the deployment
##
extraVolumes:
  - name: redmine-init-volume
    configMap:
      name: redmine-init-configmap

## Extra volume mounts to add to the container
##
extraVolumeMounts:
  - name: "redmine-init-volume"
    mountPath: "/post-init.sh"
    subPath: post-init.sh
```

#### Change the probes URI

```yaml
## Configure extra options for liveness and readiness probes
## ref: https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes/#configure-probes)
##
startupProbe:
  enabled: true
  path: /redmine/
---
readinessProbe:
  enabled: true
  path: /redmine/
```

### Backup and restore

To back up and restore Helm chart deployments on Kubernetes, you need to back up the persistent volumes from the source deployment and attach them to a new deployment using [Velero](https://velero.io/), a Kubernetes backup/restore tool. Find the instructions for using Velero in [this guide](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-backup-restore-deployments-velero-index.html).

## Persistence

The [Bitnami Redmine](https://github.com/bitnami/containers/tree/main/bitnami/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
2. Create the PersistentVolumeClaim
3. Create the directory, on a worker
4. Install the chart

```console
helm install test --set persistence.existingClaim=PVC_REDMINE,mariadb.persistence.existingClaim=PVC_MARIADB oci://REGISTRY_NAME/REPOSITORY_NAME/redmine
```

> 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`.

### NetworkPolicy parameters

| Name                                    | Description                                                     | Value  |
| --------------------------------------- | --------------------------------------------------------------- | ------ |
| `networkPolicy.enabled`                 | Specifies whether a NetworkPolicy should be created             | `true` |
| `networkPolicy.allowExternal`           | Don't require server label for connections                      | `true` |
| `networkPolicy.allowExternalEgress`     | Allow the pod to access any range of port and all destinations. | `true` |
| `networkPolicy.extraIngress`            | Add extra ingress rules to the NetworkPolicy                    | `[]`   |
| `networkPolicy.extraEgress`             | Add extra ingress rules to the NetworkPolicy                    | `[]`   |
| `networkPolicy.ingressNSMatchLabels`    | Labels to match to allow traffic from other namespaces          | `{}`   |
| `networkPolicy.ingressNSPodMatchLabels` | Pod labels to match to allow traffic from other namespaces      | `{}`   |

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

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

```console
helm install my-release \
  --set redmineUsername=admin,redminePassword=password,mariadb.mariadb.auth.rootPassword=secretpassword \
    oci://REGISTRY_NAME/REPOSITORY_NAME/redmine
```

> 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 Redmine administrator account username and password to `admin` and `password` respectively. Additionally, it sets the MariaDB `root` 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 oci://REGISTRY_NAME/REPOSITORY_NAME/redmine
```

> 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/redmine/values.yaml)

## Upgrading

### To 34.0.0

This major release bumps the MariaDB version to 12.0. Follow the [upstream instructions](https://mariadb.com/docs/server/server-management/install-and-upgrade-mariadb/upgrading) for upgrading from MariaDB 11.8 to 12.0. No major issues are expected during the upgrade.

### To 33.0.0

This major release bumps the MariaDB version to 11.8. Follow the [upstream instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-11-4-to-mariadb-11-8/) for upgrading from MariaDB 11.4 to 11.8. No major issues are expected during the upgrade.

### To 32.1.0

This version introduces image verification for security purposes. To disable it, set `global.security.allowInsecureImages` to `true`. More details at [GitHub issue](https://github.com/bitnami/charts/issues/30850).

### To 31.0.0

This major bump updates the MariaDB subchart to version 20.0.0. This subchart updates the StatefulSet objects `serviceName` to use a headless service, as the current non-headless service attached to it was not providing DNS entries. This will cause an upgrade issue because it changes "immutable fields". To workaround it, delete the StatefulSet objects as follows (replace the RELEASE_NAME placeholder):

```shell
kubectl delete sts RELEASE_NAME-mariadb --cascade=false
```

Then execute `helm upgrade` as usual.

### To 30.0.0

This major updates the PostgreSQL subchart to its newest major, 16.0.0, which uses PostgreSQL 17.x.  Follow the [official instructions](https://www.postgresql.org/docs/17/upgrading.html) to upgrade to 17.x.

### To 29.0.0

This major release bumps the MariaDB version to 11.4. Follow the [upstream instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-11-3-to-mariadb-11-4/) for upgrading from MariaDB 11.3 to 11.4. No major issues are expected during the upgrade.

### To 28.0.0

This major bump changes the following security defaults:

- `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`.
- The `networkPolicy` section has been normalized amongst all Bitnami charts. Compared to the previous approach, the values section has been simplified (check the Parameters section) and now it set to `enabled=true` by default. Egress traffic is allowed by default and ingress traffic is allowed by all pods but only to the ports set in `containerPorts` and `extraContainerPorts`.

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.

Also, this major release bumps the MariaDB chart version to [18.x.x](https://github.com/bitnami/charts/pull/24804); no major issues are expected during the upgrade.

### To 27.0.0

This major release bumps the PostgreSQL chart version to [14.x.x](https://github.com/bitnami/charts/pull/22750) and MariaDB to [16.x.x](https://github.com/bitnami/charts/pull/23054); no major issues are expected during the upgrade.

### To 26.0.0

This major release bumps the MariaDB version to 11.2. No major issues are expected during the upgrade.

### To 25.0.0

This major release bumps the MariaDB version to 11.1. No major issues are expected during the upgrade.

### To 24.0.0

This major updates the PostgreSQL subchart to its newest major, 13.0.0. [Here](https://github.com/bitnami/charts/tree/master/bitnami/postgresql#to-1300) you can find more information about the changes introduced in that version.

### To 23.0.0

This major release bumps the MariaDB version to 11.0. Follow the [upstream instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-10-11-to-mariadb-11-0/) for upgrading from MariaDB 10.11 to 11.0. No major issues are expected during the upgrade.

### To 22.0.0

This major release bumps the MariaDB version to 10.11. Follow the [upstream instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-10-6-to-mariadb-10-11/) for upgrading from MariaDB 10.6 to 10.11. No major issues are expected during the upgrade.

### To 21.0.0

This major updates the PostgreSQL subchart to its newest major, 12.0.0. [Here](https://github.com/bitnami/charts/tree/master/bitnami/postgresql#to-1200) you can find more information about the changes introduced in that version.

### To 20.0.0

The MariaDB subchart has been updated to the latest version (now it uses 10.6). No major issues are expected during the upgrade.

### To 18.0.0

This major release updates the PostgreSQL subchart to its newest major *11.x.x*, which contain several changes in the supported values (check the [upgrade notes](https://github.com/bitnami/charts/tree/master/bitnami/postgresql#to-1100) to obtain more information).

#### How to upgrade to version 18.0.0

To upgrade to *18.0.0* from *17.x* using PostgreSQL as database, it should be done reusing the PVC(s) used to hold the data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is *redmine* and the release namespace *default*):

1. Obtain the credentials and the names of the PVCs used to hold the data on your current release:

```console
export REDMINE_PASSWORD=$(kubectl get secret --namespace default redmine -o jsonpath="{.data.redmine-password}" | base64 --decode)
export POSTGRESQL_PASSWORD=$(kubectl get secret --namespace default redmine-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)
export POSTGRESQL_PVC=$(kubectl get pvc -l app.kubernetes.io/instance=redmine,app.kubernetes.io/name=postgresql,role=primary -o jsonpath="{.items[0].metadata.name}")
```

1. Delete the PostgreSQL statefulset (notice the option *--cascade=false*) and secret:

```console
kubectl delete statefulsets.apps --cascade=false redmine-postgresql
kubectl delete secret redmine-postgresql --namespace default
```

1. Upgrade your release using the same PostgreSQL version:

```console
CURRENT_PG_VERSION=$(kubectl exec redmine-postgresql-0 -- bash -c 'echo $BITNAMI_IMAGE_VERSION')
helm upgrade redmine bitnami/redmine \
  --set databaseType=postgresql \
  --set redminePassword=$REDMINE_PASSWORD \
  --set postgresql.image.tag=$CURRENT_PG_VERSION \
  --set postgresql.auth.password=$POSTGRESQL_PASSWORD \
  --set postgresql.persistence.existingClaim=$POSTGRESQL_PVC
```

1. Delete the existing PostgreSQL pods and the new statefulset will create a new one:

```console
kubectl delete pod redmine-postgresql-0
```

### 17.0.0

In this version, the `image` block is defined once and is used in the different templates, while in the previous version, the `image` block was duplicated for the main container and the mail receiver one:

```yaml
image:
  registry: docker.io
  repository: bitnami/redmine
  tag: 4.2.2
```

VS

```yaml
image:
  registry: docker.io
  repository: bitnami/redmine
  tag: 4.2.2
---
mailReceiver:
  image:
    registry: docker.io
    repository: bitnami/redmine
    tag: 4.2.2
```

See [PR#7114](https://github.com/bitnami/charts/pull/7114) for more info about the implemented changes

### To 16.0.0

The [Bitnami Redmine](https://github.com/bitnami/containers/tree/main/bitnami/redmine) image was refactored and now the source code is published in GitHub in the `rootfs` folder of the container image repository.

#### Upgrading Instructions

To upgrade to *16.0.0* from *15.x*, it should be done enabling the "volumePermissions" init container. To do so, follow the instructions below (the following example assumes that the release name is *redmine* and the release namespace *default*):

1. Obtain the credentials on your current release:

```console
export REDMINE_PASSWORD=$(kubectl get secret --namespace default redmine -o jsonpath="{.data.redmine-password}" | base64 --decode)
export MARIADB_ROOT_PASSWORD=$(kubectl get secret --namespace default example-mariadb -o jsonpath="{.data.mariadb-root-password}" | base64 --decode)
export MARIADB_PASSWORD=$(kubectl get secret --namespace default example-mariadb -o jsonpath="{.data.mariadb-password}" | base64 --decode)
```

1. Upgrade your release:

```console
helm upgrade redmine bitnami/redmine \
  --set redminePassword=$REDMINE_PASSWORD \
  --set mariadb.auth.rootPassword=$MARIADB_ROOT_PASSWORD \
  --set mariadb.auth.password=$MARIADB_PASSWORD \
  --set volumePermissions.enabled=true
```

### To 15.0.0

[On November 13, 2020, Helm v2 support was formally finished](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.

#### What changes were introduced in this major version?

- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Move dependency information from the *requirements.yaml* to the *Chart.yaml*
- After running *helm dependency update*, a *Chart.lock* file is generated containing the same structure used in the previous *requirements.lock*
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Chart.
- Additionally updates the MariaDB & PostgreSQL subcharts to their newest major *9.x.x* and *10.x.x*, respectively, which contain similar changes.

#### Considerations when upgrading to this version

- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version does not support Helm v2 anymore.
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3.

#### How to upgrade to version 15.0.0

To upgrade to *15.0.0* from *14.x*, it should be done reusing the credentials on your previous release. To do so, follow the instructions below (the following example assumes that the release name is *redmine* and the release namespace *default*):

1. Obtain the credentials on your current release:

```console
export REDMINE_PASSWORD=$(kubectl get secret --namespace default redmine -o jsonpath="{.data.redmine-password}" | base64 --decode)
export MARIADB_ROOT_PASSWORD=$(kubectl get secret --namespace default example-mariadb -o jsonpath="{.data.mariadb-root-password}" | base64 --decode)
export MARIADB_PASSWORD=$(kubectl get secret --namespace default example-mariadb -o jsonpath="{.data.mariadb-password}" | base64 --decode)
```

1. Upgrade your release:

```console
helm upgrade redmine bitnami/redmine \
  --set redminePassword=$REDMINE_PASSWORD \
  --set mariadb.auth.rootPassword=$MARIADB_ROOT_PASSWORD \
  --set mariadb.auth.password=$MARIADB_PASSWORD
