Create .env file which will be consumed via docker-compose.yml

• nano .env and paste the following variables

      # will be used by only in docker file to inject variables in docker-compose.yml
      # port will set by docker only
      PORT=5050
      DB_PORT=5090
      DB_NAME=SKN_db
      DB_USERNAME=username
      DB_PASSWORD=password
  
      BASE_URL=https://localhost:5090/
      CERT_PATH=server.cert
      KEY_PATH=server.key
      FACEBOOK_CLIENT_ID=775340076293966
      FACEBOOK_CLIENT_SECRET=3b0be9c79d15fcdf68fbe4561d38e2b2
  
      REDIS_PASS=skn_dev_redis

  • NOTE: all these variables will only be consumed via docker-compose.yml file and will not affect the code.
  • BASE_URL is the url which our node app is running
  • PORT is the port which app will be running on via docker-compose up (this value can be changed as you want)
  • DB_PORT is the port will be exposed to your localhost incase you want to connect to db vai any tool eg. no sql booster (this value can be changed as you want)
  • Other variables is straight forward to conclude.

Create docker.env file which you will be using in code in docker environment

• nano docker.env and paste the following variables

          # will be used in code in docker environment
  
          DB_HOST=skndb
          DB_PORT=27017
          DB_NAME=SKN_db
          DB_USERNAME=username
          DB_PASSWORD=password
          jwtPrivateKey=123
  

      REDIS_PASS=skn_dev_redis
      # should be the redis container name
      REDIS_HOST=cache
  
      BASE_URL=https://localhost:5050
      CERT_PATH=server.cert
      KEY_PATH=server.key
      FACEBOOK_CLIENT_ID=775340076293966
      FACEBOOK_CLIENT_SECRET=3b0be9c79d15fcdf68fbe4561d38e2b2
  

  
  - `BASE_URL` is the url which our node app is running
  - `DB_HOST` is the name of the host of our db in docker environment.
  - `DB_PORT` is the port which we will use to connect to db via code.
    - **NOTE** This port value should be _27017_ cuz we are connecting to the image(skndb) itself not the mapping port in our host(localhost)
  - Other variables is straight forward to conclude.
  
  

Happy coding via docker-compose up

• Your app is running and accessible on localhost:${PORT} => which comes from .env file
• Your app is running and accessible on mongodb://${DB_USERNAME}:${DB_PASSWORD}@localhost:${PORT}/?authSource=admin => which comes from .env file

Create local.env file which you will be using in code in local/debug environment

• nano local.env and paste the following variables

         # will be used in code in local and debug environment
  
        PORT=6060
        DB_HOST=localhost
  
          # should be exactly as DB_PORT in .env when running on docker db
          #                but if we want to connect to local mongo host should be 27017
          DB_PORT=5090
          DB_NAME=SKN_db
          DB_USERNAME=username
          DB_PASSWORD=password
          jwtPrivateKey=123
  
          REDIS_PASS=skn_dev_redis
          REDIS_HOST=localhost
  
          BASE_URL=https://localhost:5090/
          CERT_PATH=server.cert
          KEY_PATH=server.key
          FACEBOOK_CLIENT_ID=775340076293966
          FACEBOOK_CLIENT_SECRET=3b0be9c79d15fcdf68fbe4561d38e2b2

  • To work with redis you will need to run the compose(at least the redis service)
  • PORT is the port which app will be running on in local/debug mode (this value can be changed as you want)
  • BASE_URL is the url which our node app is running
  • DB_HOST is the name of the host of our db in local/debug mode.
  • DB_PORT is the port which we will use to connect to db via code.
    • NOTE This port value should be same as DB_PORT in .env file cuz we are connecting to the db which is running on the image(skndb).
  • Other variables is straight forward to conclude.

Do the last steps in setting up local.env file but change the DB_PORT to 27017

Happy coding via npm run local/ debug mode by F5
