Access docker containers started with docker-compose from another Docker container

[robertmircea]

I have a docker-compose project with multiple docker containers hosted with Orb. I am trying to access one of the containers from the project from another docker container which is running outside docker-compose project.

Let's say NATS server is running at address nats.project.orb.local 4224. The NATS server is accessible from local Mac, but is not accessible from another Docker container. Any idea why?

From local Mac shell:

ping nats.project.orb.local
PING nats.project.orb.local (10.200.0.2): 56 data bytes
64 bytes from 10.200.0.2: icmp_seq=0 ttl=63 time=1.171 ms****

From another Docker container outside the project running in Orb stack:

/app $ ping nats.project.orb.local
PING nats.project.orb.local (10.200.0.2): 56 data bytes
^C

telnet on port 4224 (TCP) is not working either.

Thanks for describing this so clearly. I think this is the same issue as #576 so I've responded there.
