docker compose mysql external ip

Hello, I have a doubt about the docker and docker compose. I understand the basics of docker, and the philosophy of docker compose, I try different things and general work fine.

I make some proves with and nginx and php, mysql and more and seems all its okey, but when i want to access to a mysql inside a continer i can't get the exact IP adress from the hsot and conect for example with SequelPro.

The last test I try is with docker-symfony, if anyone can help me to access the mysql from my host I appreciate!

#docker

You don't need an IP Adress... The Mysql Container is reachable from Sequel via 127.0.0.1 and the port you give it within your docker-compose.

And if you need to access the mysql container from any other container you can just use the name as host. Docker knows where your containers are and which IPs they have.

If you want to go further, have look at creating custom networks.

Yes, thanks for all the info! The only thing i had to do is running this commands "docker-compose run --service-ports db" and the ports from the container are available from the local host!

It's a bit hard changing your mind from traditional server configuration or vagrant with virtual machine to a docker :)

Yes it is. But just imagine, all your Containers are running in an local VM, and ports are mapped to the Containers. So, if you can reach a web container via localhost and custom port in the browser, you can also reach mysql via this custom port. ;)
