Deploy Chatwoot using Helm Charts

This guide will help you to deploy a production ready Chatwoot instance with Helm Charts.

To quickly try out the charts, follow the two steps below. For a production deployment, please make sure to pass in the required arguments to helm.

helm repo add chatwoot https://chatwoot.github.io/charts
helm install chatwoot chatwoot/chatwoot

Prerequisites

  • Kubernetes 1.16+
  • Helm 3.1.0+
  • PV provisioner support in the underlying infrastructure

The helm installation will create 3 "Persistent Volume Claims" for redis, rails and postgres. Setup up a default "Storage Class" (for automatic PV) or create 3 "Persistent Volumes" with the size of 8GB, before installing chatwoot. If the "Persistent Volume Claims" do not claim the "Persistent Volumes", leave storageClassName blank (inside the PV .yaml files).

Installing the chart

To install the chart with the release name chatwoot:

helm install chatwoot chatwoot/chatwoot

The command deploys Chatwoot on the Kubernetes cluster in the default configuration. The 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 chatwoot deployment:

helm delete chatwoot

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

Note: Persistent volumes are not deleted automatically. They need to be removed manually.

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

helm install my-release \
--set env.FRONTEND_URL="chat.yourdomain.com"\
chatwoot/chatwoot

The above command sets the Chatwoot server frontend URL to chat.yourdoamain.com.

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

helm install my-release -f values.yaml chatwoot/chatwoot

Tip You can use the default values.yaml file.

Postgres

PostgreSQL is installed along with the chart if you choose the default setup. To use an external Postgres DB, please set postgresql.enabled to false and set the variables under the Postgres section above.

Redis

Redis is installed along with the chart if you choose the default setup. To use an external Redis DB, please set redis.enabled to false and set the variables under the Redis section above.

Upgrading

To 0.6.x

Existing labels were causing issues with helm upgrade. 0.6.x introduces breaking changes related to selector labels used for deployements. Please delete your helm release and recreate. Deleting your helm release will not delete your persistent volumes used for redis and postgres and as such your data should be safe.

helm delete chatwoot
helm repo update
helm install chatwoot chatwoot/chatwoot

Error debugging

"pod has unbound immediate PersistentVolumeClaims"

Make sure the "Persistent Volume Claims" can be satisfied. Refer to: Prerequisites
