Pre-requisites

Before proceeding, make sure you have the latest version of docker and docker-compose installed.

As of now[at the time of writing this doc], we recommend

```bash
$ docker --version
Docker version 19.03.3, build a872fc2f86
$ docker-compose --version
docker-compose version 1.25.3, build d4d1b42b
```

Development environment

1. Clone the repository.

   $ git clone https://github.com/chatwoot/chatwoot.git
   

2. Make a copy of the example environment file and modify as required [optional].

   $ cp .env.example .env
   

   If you want to set the password for redis when you run docker-compose, set any string value to the environment variable REDIS_PASSWORD in the .env file. This will secure the redis running inside docker-compose with the given password. Also this will be automatically picked up by the app server and sidekiq, to authenticate while making connections to redis server.

3. Build the images.

   $ docker-compose build
   

4. After building the image or after destroying the stack you would have to reset the database using the following command.

   $ docker-compose run --rm rails bundle exec rails db:reset
   

5. To run the app,

   $ docker-compose up
   

   • Access the rails app frontend by visiting http://0.0.0.0:3000/
   • Access Mailhog inbox by visiting http://0.0.0.0:8025/ (You will receive all emails going out of the application here)
   • Access Sidekiq Web UI by visiting http://0.0.0.0:3000/sidekiq (You need to login with administrator account to access sidekiq)

   Login with credentials

       url: http://localhost:3000
       user_name: john@acme.inc
       password: 123456
   

6. To stop the app,

   $ docker-compose down
   

Running rspec tests

For running the complete rspec tests,

```bash
$ docker-compose run --rm rails bundle exec rspec
```

For running specific test,

```bash
$ docker-compose run --rm rails bundle exec rspec spec/<path-to-file>:<line-number>
```

Production environment

To debug the production build locally, set SECRET_KEY_BASE environment variable in your .env file and then run the below commands:

```bash
$ docker-compose -f docker-compose.production.yaml build
$ docker-compose -f docker-compose.production.yaml up
```

Debugging mode

To use debuggers like byebug or binding.pry, use the following command to bring up the app instead of docker-compose up.

```bash
   $ docker-compose run --rm --service-port rails  
```

Troubleshooting

If there is an update to any of the following

• dockerfile
• gemfile
• package.json
• schema change

Make sure to rebuild the containers and run db:reset.

```bash
$ docker-compose down
$ docker-compose build
$ docker-compose run --rm rails bundle exec rails db:reset
$ docker-compose up
```
