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`
* Added dotenv-rails gem to manage environment variables
* Added dotenv-rails gem to manage environment variables
* Removed figaro which was used earlier for this purpose
* Standardized variable names
* Changed all env variables to be upper case. This included changes in files referencing env variables.
* Added example env file with all variables set to empty value
* Removed the earlier setup of copying application.yml and database.yml and the scripts and documentation associated to this
* Docker setup
* Added docker file for building the docker images
* Added entrypoint.sh script which is referenced inside the Docker image
* Cloned the Procfile for development using docker which has slight change compared to regular procfile
* Added the docker-compose.yml which has 3 service's configuration, postgres, redis and chatwoot server and a mounted volume for postgres
* Added docker related info to documentation
* Added the docker setup info in the documentation
* Added info for using`rbenv` instead of rvm for managing ruby versions
