Hi everyone, I have a rather odd issue where containers running web servers that were created in different docker-compose files CAN “wget” each other on OSX, but not on linux.
Let’s say we have two http services defined in different docker compose files like this:
docker-compose file 1
docker-compose file 2
Both containers have a common domain name defined in their hosts file that associates the domain with the host computer IP address, e.g.
If I attach a shell to http-service-1, on OSX this works:
However it hangs and doesn’t work on Ubuntu / linux.
It is of note that both docker-compose files create different networks (i.e. they use the default network creation)
So I guess I have a few questions:
Should this work at all? Why does it work on OSX?
What can I do to make it work on Linux.
Also of note, I have verified that if I create a custom network, attach both docker-compose files to that custom network and then use the service names for the wget,
then it works.
Unfortunately I’m not in control of the docker setup (just a consumer of the existing setup). If I have to however, I will recommend a change if the current setup is not best practice.
Thanks in advance!!
