Sounds good with installation till i get stuck with npm to communicate with the discourse host; you mention to put the IP of the data container inside the mySQL host of the npm compose file

 environment:
      DB_MYSQL_HOST: "db"
      DB_MYSQL_PORT: 3306
      DB_MYSQL_USER: "npm"
      DB_MYSQL_PASSWORD: "npm"
      DB_MYSQL_NAME: "npm"

but when i change the (DB_MYSQL_HOST) to data container it’s show me connection refused.

connect ECONNREFUSED 172.17.0.2:3306 <-- error when npm in discours network (network_mode: bridge).
getaddrinfo ENOTFOUND db <-- error when the mySQL in npm compose file defind as "db".

any suggestion to let step 3. working with me ?
