I am loosing my mind trying to set up my golang and docker env. I am using docker compose which seems to book both images fine but when I try run and go lang operations I get an error.
The spacing in your yaml file is important, your mysql line should line up with your app line.
You have to add a
links:
- mysql
line in under your app: section so it knows to connect the two.
Look here https://github.com/gpuenteallott/golang-mysql-docker-setup/blob/master/docker-compose.yml for a decent working example.
