Error: duplicated outer port

I've been following this tutorial on docker cloud: https://docs.docker.com/docker-cloud/apps/load-balance-hello-world/

I've been getting errors when trying to expose port 80 using haproxy.

Solution

  • I wasn't able to figure this out using the UI. I believe this is a bug that was introduced recently. But as somebody suggested on Docker forums, you can use the CLI instead. I was able to create a new proxy on Cloud with this command

    docker-cloud service create -n haproxy --autorestart ON_FAILURE --role global -p 80:80 --link-service demo-blue:demo-blue dockercloud/haproxy
docker-lcoud service start <UUID>

    You should be able to do something similar as well.
