Deploy Chatwoot on Kubernetes 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 using your custom values.yaml file.

helm repo add chatwoot
helm install chatwoot chatwoot/chatwoot


  • 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, use the following. To deploy it in chatwoot namespace, pass -n chatwoot to the command.

helm install chatwoot chatwoot/chatwoot -f <your-custom-values.yaml> #-n 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.

Other Parameters

existingEnvSecretstring""Allows the use of an existing secret to set env variables

Install with custom parameters

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

helm install my-release \
--set env.FRONTEND_URL=""\

The above command sets the Chatwoot server frontend URL to

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.


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 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.


To enable horizontal pod autoscaling, set web.hpa.enabled and worker.hpa.enabled to true. Also make sure to uncomment the values under, resources.limits and resources.requests. This assumes your k8s cluster is already having a metrics-server. If not, deploy metrics-server with the following command.

kubectl apply -f


Do helm repo update and check the version of charts that is going to be installed. Helm charts follows semantic versioning and so if the MAJOR version is different from your installed version, there might be breaking changes. Please refer to the changelog before upgrading.

# update helm repositories
helm repo update
# list your current installed version
helm list
# show the latest version of charts that is going to be installed
helm search repo chatwoot
#if it is major version update, refer to the changelog before proceeding
helm upgrade chatwoot chatwoot/chatwoot -f <your-custom-values>.yaml

To 1.x.x

Make sure you are on Chatwoot helm charts version 0.9.0 before upgrading to version 1.x.x. If not, please upgrade to 0.9.0 before proceeding.

helm repo update
helm upgrade chatwoot chatwoot/chatwoot --version="0.9.0" -f <your-custom-values> --debug

This release changes the postgres and redis versions. This is a breaking change and requires manual data migration if you are not using external postgres and redis.

Note: This release also changes the postgres and redis auth paramaters values under .Values.redis and .Values.postgres. Make the necessary changes to your custom values.yaml file if any. Values.postgresqlDatabase is now Values.auth.postgresqlDatabase, Values.postgresqlUsername is now Values.auth.postgresqlUsername and Values.postgresqlPassword is renamed to Values.auth.postgresqlPassword.

Note: Append the kubectl commands with -n chatwoot, if you have deployed it under the chatwoot namespace.

Before updating,

  1. Set the replica count to 0 for both Chatwoot web(.Values.web.replicaCount) and worker(.Values.worker.replicaCount) replica sets. Applying this change will bring down the pods count to 0. This is to ensure the database will not be having any activity and is in a state to backup.
helm upgrade chatwoot chatwoot/chatwoot --version="0.9.0" --namespace ug3 -f --create-namespace --debug
  1. Log into the postgres pod and take a backup of your database.

    kubectl exec -it chatwoot-chatwoot-postgresql-0 -- /bin/sh
    env | grep -i postgres_password #get postgres password to use in next step
    pg_dump -Fc --no-acl --no-owner -U postgres chatwoot_production > /tmp/cw.dump
  2. Copy the backup to your local machine.

    kubectl cp pod/chatwoot-chatwoot-postgresql-0:/tmp/cw.dump ./cw.dump
  3. Delete the deployments.

    helm delete chatwoot
    kubectl get pvc
    # this will delete the database volumes
    # make sure you have backed up before proceeding
    kubectl delete pvc <data-postgres->
    kubectl delete pvc <redis>
  4. Update and install new version of charts.

helm repo update
#reset web.replicaCount and worker.replicaCount to your previous values
helm install chatwoot chatwoot/chatwoot -f <your-values.yaml> #-n chatwoot
  1. Copy the local db backup into postgres pod.
kubectl cp cw.dump chatwoot-chatwoot-postgresql-0:/tmp/cw.dump
  1. Exec into the postgres pod and drop the database.
 kubectl exec -it chatwoot-chatwoot-postgresql-0 -- /bin/sh
psql -u postgres -d postgres
# this is a destructive action
# remove -- to take effect
-- DROP DATABASE chatwoot_production with (FORCE);
  1. Restore the database from the backup. If you are seeing no errors, the databse has been restored and you are good to go.
 pg_restore --verbose --clean --no-acl --no-owner --create -U postgres -d postgres /tmp/cw.dump
  1. Exec into the web pod and remove the onboarding variable in redis.
kubectl exec -it chatwoot-web-xxxxxxxxxx -- /bin/sh
RAILS_ENV=production bundle exec rails c
  1. Load the Chatwoot web url, log in using the old credentials and verify the contents. Voila! Thats it!!

To 0.9.x

This release adds support for horizontal pod autoscaling(hpa) for chatwoot-web and chatwoot-worker deployments. Also, this changes the default redis replica count to 1. The Values.web.replicas and Values.worker. replicas parameters where renamed to Values.web.replicaCount and Values.worker.replicaCount respectively. Also services.internlPort was renamed to services.internalPort.

Please make the necessary changes in your custom values file if needed.

To 0.8.x

Move from Kubernetes ConfigMap to Kubernetes Secrets for environment variables. This is not a breaking change.

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


pod has unbound immediate PersistentVolumeClaims

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

ActionController::InvalidAuthenticityToken HTTP Origin header ( didn't match request.base_url (

If you are recieving this error when trying to access the superadmin panel, configure your ingress controller to forward the protocol of the origin request. For nginx ingress, you can do this by setting the proxy_set_header X-Forwarded-Proto https; config. Refer this issue to learn more.
