Can't Connect to MySQL Using Docker

[wioux]

Make sure this environment variable is set in the app container: MYSQL_HOST=db. It's recommended to start development by creating a .env file with the initial values in .env.example.

Hello,

My .env has MYSQL_HOST=db in my .env and when I run sudo docker-compose up --build I get:

db_1 | 2017-06-21T14:27:52.538551Z 4 [Note] Aborted connection 4 to db: 'phantom_dc_development' user: 'phantom_dc' host: '172.18.0.3' (Got an error reading communication packets)

So, also having the same error.

Hi @mr-sk. This is a separate thing, as in your case the app has connected to the db instance but then that connection breaks, while @asithade's app container is not connecting to the db server at all. If you're having problems can you open a separate issue? Be sure to include the app container's output as well around the time of the error.

Thanks,
Peter

Hi there,

I actually get the same error as him when I set it to db.

That line will pop up occasionally during a normal boot of the app. Closing this issue for now, but please open another one if you have other problems.
