Install containerized Kolab with k3s

Kolab can be deployed via k3s for a single host installation.

Please note that this deployment does not come with support, and is not suitable for large production deployments as it does not scale beyond one host.

Requirements

A basic kolab deployment will require:

• Approximately 10GB of disk space for container image storage

For a publicly available deployment the following will be required in addition:

• A public IP to be able to receive email or use webrtc
• A domain name with all the necessary DNS records

Deploy via helm chart on k3s

Suitable to just get a system running locally for evaluation or as a basis for a production deployment.

A helm chart and prebuilt images for a kubernetes deployment are available here: https://mirror.apheleia-it.ch/pub/kolab-kubernetes-latest.tar.gz

The tarball contains instructions as well as a kolabctl script to setup a k3s based deployment.

Please note:

• The prebuilt images are based on the same sources as kolab.git (and you can build your own images instead).
• The images and helm chart come without support or guarantees for backwards compatibility.
• If you want to run this in production you need to either know what you’re doing or buy support. Patches are of course welcome.
