Helm Chart

Basic commands

helm repo add openproject https://charts.openproject.org
helm upgrade --create-namespace --namespace openproject --install my-openproject openproject/openproject


This chart bootstraps an OpenProject instance, optionally with a PostgreSQL database and Memcached.


  • Kubernetes 1.16+
  • Helm 3.0.0+
  • PV provisioner support in the underlying infrastructure

ReadWriteMany volumes

By default and when using filesystem-based attachments, OpenProject requires the Kubernetes cluster to support ReadWriteMany (rwx) volumes. This is due to the fact that multiple container instances need access to write to the attachment storage.

To avoid using ReadWriteMany, you will need to configure an S3 compatible object storage instead which is shown in the advanced configuration guide.

  enabled: false

  enabled: true
  # etc.

Installing the Chart

You can install the chart with the release name my-openproject in its own namespace like this:

helm upgrade --create-namespace --namespace openproject --install my-openproject openproject/openproject

The namespace is optional, but using it does make it easier to manage the resources created for OpenProject.

Helm chart signing

We sign our chart using the Helm Provenance and Integrity functionality. You can find the used public key here

We recommend using the Helm GnuPG plugin. With it you can manually verify the signature like this:

helm repo add openproject https://charts.openproject.org
helm fetch --prov openproject/openproject
helm gpg verify openproject-*.tgz


Configuration of the chart takes place through defined values, and a catch-all entry environment to provide all possible variables through ENV that OpenProject supports. To get more information about the possible values, please see our guide on environment variables.

Available OpenProject specific helm values

We try to map the most common options to chart values directly for ease of use. The most common ones are listed here, feel free to extend available values through a pull request.

OpenProject image and version

By default, the helm chart will target the latest stable major release. You can define a custom supported docker tag using image.tag. Override container registry and repository using image.registry and image.repository, respectively.

HTTPS mode

Regardless of the TLS mode of ingress, OpenProject needs to be told whether it’s expected to run and return HTTPS responses (or generate correct links in mails, background jobs, etc.). If you’re not running https, then set openproject.https=false.

Seed locale (13.0+)

By default, demo data and global names for types, statuses, etc. will be in English. If you wish to set a custom locale, set openproject.seed_locale=XX, where XX can be a two-character ISO code. For currently supported values, see the OPENPROJECT_AVAILABLE__LANGUAGES default value in the environment guide.

Admin user (13.0+)

By default, OpenProject generates an admin user with password admin which is required to change after first interactive login. If you’re operating an automated deployment with fresh databases for testing, this default approach might not be desirable.

You can customize the password as well as name, email, and whether a password change is enforced on first login with these variables:

openproject.admin_user.name="Firstname Lastname"

Updating the configuration

The OpenProject configuration can be changed through environment variables. You can use helm upgrade to set individual values.

For instance:

helm upgrade --reuse-values --namespace openproject my-openproject --set environment.OPENPROJECT_IMPRESSUM__LINK=https://www.openproject.org/legal/imprint/ --set environment.OPENPROJECT_APP__TITLE='My OpenProject'

Find out more about the configuration section.

Uninstalling the Chart

To uninstall the release with the name my-openproject do the following:

helm uninstall --namespace openproject my-openproject

Note: This will not remove the persistent volumes created while installing. The easiest way to ensure all PVCs are deleted as well is to delete the openproject namespace (kubectl delete namespace openproject). If you installed OpenProject into the default namespace, you can delete the volumes manually one by one.


Web deployment stuck in CrashLoopBackoff

Describing the pod may yield an error like the following:

65s)  kubelet            Error: failed to start container "openproject": Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error setting cgroup config for procHooks process: failed to write "400000": write /sys/fs/cgroup/cpu,cpuacct/kubepods/burstable/pod990fa25e-dbf0-4fb7-9b31-9d7106473813/openproject/cpu.cfs_quota_us: invalid argument: unknown

This can happen when using minikube. By default, it initialises the cluster with 2 CPUs only.

Either increase the cluster’s resources to have at least 4 CPUs or install the OpenProject helm chart with a reduced CPU limit by adding the following option to the install command:

--set resources.limits.cpu=2


For OpenProject to work in OpenShift without further adjustments, you need to use the following pod security context.

  supplementalGroups: [1000]
  fsGroup: null

By default OpenProject requests fsGroup: 1000 in the pod security context. This is not allowed by default. You have to allow it using a custom SCC (Security Context Constraint) in the cluster.

The use of supplementalGroups is not necessary if you request the correct UID in the security context.

  runAsUser: 1000
  runAsGroup: 1000

But this will not be allowed by default either. So the easiest way is the use of the podSecurityContext shown above.

Due to the default restrictions in OpenShift there may also be issues running PostgreSQL and memcached. Again, you may have to create an SCC to fix this or adjust the policies in the subcharts accordingly.

Assuming no further options for both, simply disabling the security context values to use the default works as well.
