Caprover Chatwoot Production deployment guide

​

Caprover Overview

Caprover is an extremely easy to use application server management tool. It is blazing fast and uses Docker under the hood. Chatwoot has been made available as a one-click app in Caprover, and the deployment process is straightforward.

​

Setup Chatwoot Using Caprover

​

1. Install Caprover on your VM

Finish your Caprover installation by referring to Getting started guide.

​

2. Install Chatwoot

Chatwoot is available in the one-click apps option in Caprover. Search for Chatwoot in the list of one-click apps. Replace the default version with the latest version of chatwoot. Use appropriate values for the Postgres and Redis passwords and click install. It should only take a few minutes.

​

3. Finish the setup

Head over to the web service in the Caprover applications and enable Websocket Support in the HTTP settings to true. You could also enable https for the application.

​

4. Configure environment variables

Caprover will take care of Postgres and Redis installation, along with the app and worker servers. We would advise you to replace the Database/Redis services with managed/standalone servers once you start scaling.

Also, ensure to set the appropriate environment variables for email, Object Store service etc. using our Environment variables guide

​

Common Errors

​

API requests failing with “You need to sign in or sign up before continuing.”

Nginx by default strip of headers with _ . Head over to the Nginx configuration option in caprover under the Chatwoot web and add the following directive.

Access the Caprover web dashboard > Apps > Apps Edit > Edit Default Nginx Configurations. Refer https://caprover.com/docs/nginx-customization.html for more details.

# Nginx strips out underscore in headers by default
# Chatwoot relies on underscore in headers for API
# Make sure that the config is set to on.
underscores_in_headers on;

Issues related to storage persistance

Please setup a cloud storage like s3 or gcs bucket or any s3 api compatible service as the active storage service. Caprover installation needs this for storage persistance. Refer the storage guide.
