Inter-container connection via localhost
I would like to set up my containers so that they connect to each other via localhost.
My setup is a main application container and two other containers that it needs to connect to (ActiveMQ and Wiremock).
I already run ActiveMQ and Wiremock in containers with the relevant ports exposed, and the main application runs through IntelliJ and connects to these. However, when I am not developing the main applications, I would like to run it in a container for simplicity but it cannot connect to the ports exposed by the others.
--net=host doesn’t seem to work, nor does creating a network
docker network create <NAME> and assigning it in the
docker run with
The application already runs in a container in other environments on the host network.
One Solution collect form web for “Inter-container connection via localhost”
docker creates a default network in which all containers run, and sets a network name for each of your containers, using the container name.
if you have a contained named
mq for your ActiveMQ, then you would use something like
tcp://mq:61616 (or whatever protocol / port you have configured) from your other containers, to connect to it.
you shouldn’t need to set the
--net option unless you need to create a specific network for specific containers to use.
