sony-mathew 2168f823a5 [#446] Redis authentication support
Previously we did not support authentication for redis anywhere. Also in the docker compose we were exposing redis port 6379 without any authentication. In the app side for the connections that app server (for storing keys as well as for socket connections made using action cable) and Sidekiq were making to redis server did not support authentication.

With this commit, we support authentication for redis connections from app side and Sidekiq. This is supported in docker-compose as well.

The changes include :
* Added support for new env variable REDIS_PASSWORD
* This redis password is now supported by action cable connections, Sidekiq connections and app side redis connections
* Since Sidekiq did not have an initializer, added an initializer to pass custom config to Sidekiq (for now it's options for redis)
* Changes in docker-compose to pickup a password set in .env file to protect the redis server running in docker
* Added necessary documentation changes in `docker.md` and `environment-variables.md`

### Database configuration
Use the following values in database.yml which lives inside `config` directory.
```bash
development:
<<: *default
username: postgres
password:
database: chatwoot_dev
```
We use `dotenv-rails` gem to manage the environment variables. There is a file called `env.example` in the root directory of this project with all the environment variables set to empty value. You can set the correct values as per the following options. Once you set the values, you should rename the file to `.env` before you start the server.
### Configure FB Channel
To use FB Channel, you have to create an Facebook app in developer portal. You can find more details about creating FB channels [here](https://developers.facebook.com/docs/apps/#register)
```bash
FB_VERIFY_TOKEN=
FB_APP_SECRET=
FB_APP_ID=
```
### Configure emails
For development, you don't need an email provider. Chatwoot uses [letter-opener](https://github.com/ryanb/letter_opener) gem to test emails locally
For production use, use the following variables to set SMTP server.
```bash
MAILER_SENDER_EMAIL=
SMTP_ADDRESS=
SMTP_USERNAME=
SMTP_PASSWORD=
```
### Configure frontend URL
Provide the following value as frontend url
```bash
FRONTEND_URL='http://localhost:3000'
```
### Configure storage
Chatwoot currently supports only S3 bucket as storage. You can read [Creating an S3 bucket](https://docs.aws.amazon.com/AmazonS3/latest/gsg/CreatingABucket.html) and [Create an IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_create.html) to configure the following details.
```bash
S3_BUCKET_NAME=
AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
AWS_REGION=
```
### Configure Redis
For development, you can use the following url to connect to redis.
```bash
REDIS_URL='redis:://127.0.0.1:6379'
```
To authenticate redis connections made by app server and sidekiq, if it's protected by a password, use the following
environment variable to set the password.
```bash
REDIS_PASSWORD=
```
### Configure Postgres host
You can set the following environment variable to set the host for postgres.
```bash
POSTGRES_HOST=localhost
```
For production and testing you have the following variables for defining the postgres database,
username and password.
```bash
POSTGRES_DATABASE=chatwoot_production
POSTGRES_USERNAME=admin
POSTGRES_PASSWORD=password
```
### Rails Production Variables
For production deployment, you have to set the following variables
```bash
RAILS_ENV=production
SECRET_KEY_BASE=replace_with_your_own_secret_string
```
You can generate `SECRET_KEY_BASE` using `rake secret` command from project root folder.
