I started to develop with Laravel and since version 8, the Laravel development environment is shipped with docker and a tool named Sail (docker-compose).
When I configure my .env
file I need to SSH the MySQL container and get its hostname, and then SSH the Mailhog container and do the same.
Besides the above when I want to see the database from a tool like TablePlus, I couldn’t make it access the MySQL container by hostname.
I did some searches and found that I can add the hostname
directive, but I'm not sure if it's not disturbing the internal container's communication.
Can I use the hostname
directive safety in my case? is there a way to join the containers under one hostname and make it accessible from my host?
I'm running Docker Desktop for a MAC - v20.10.2
The docker-compose
for reference
