Docker machine / Docker link returns different container IP on Digital Ocean
I created a Droplet on DigitalOcean using Docker machine.
When running two containers and linking them this way from Jenkins:
/bin/bash/eval "$(docker-machine env deployment)" /bin/bash -c "docker run -d -t --name container1 -p 5000:5000 image1" /bin/bash -c "docker run -d -t --name container2 -p 5001:5001 --link container1:container1 image2"
docker inspect container1 | grep "IPAddress" I get
But when I run the Node.js application in container2 which calls
process.env.CONTAINER1_PORT_5000_TCP_ADDR it resolves to
172.17.0.7:5000 when I call container2 from its public IP (of the DO droplet) which causes to return
No route to host.
exec into container2 and run
node process.env.CONTAINER1_PORT_5000_TCP_ADDR it returns
If I ssh into the host using another user,
docker inspect container2 | grep "IPAddress" also returns
172.17.0.52 instead of
Why does the Node.js application return the wrong IP address whereas running Node.js on the command line returns a different and correct IP address?
If I run the containers locally on the Jenkins machine without docker-machine and DO, everything works fine.
