运行docker容器时连接到本地数据库

Question

I am running an app from a docker container and at some point, I had Sequel Pro connected to my local DB but since reinstalling Sequel Pro, I haven't had luck connecting back to my local DB. Where would I find the IP/port to use for this? I tried connecting to 127.0.0.1 and also tried using the IP address listed in docker inspect (container name) to no avail.

Answer 1

If you address localhost (or 127.0.0.1 ) inside your container you refer to the localhost inside the container, not the system.

You can use docker networks . If you run the container in the same network (manually adding or with a compose file) you can address like service name:port inside the network. Ports does not have published outside for this (but useful if you want to rech your DB from your system).

A alternativ way is to run your container in network mode host . In this case you run on the network interface of the docker deamon und can use localhost . But you lose some of your isolation.
