Can't start the docker image of the restcomm load balancer

Question

While trying to start the docker image found here for restcomm's load balancer I get the following error.

2017-01-09 13:40:41,359 ERROR main org.mobicents.tools.sip.balancer.BalancerRunner.start(BalancerRunner.java:280) - An unexpected error occurred while starting the load balancer

I ran the following Docker run command

docker run --name=lb -e LOG_LEVEL=all restcomm/load-balancer:latest

I tried looking up the code lines in the stack trace from the Load Balancer GitHub Repo but it appears the docker image does not contain the exact same code so the line numbers referenced don't match up.

Sorry for the delay in getting back to you. We have updated the image for the docker container. Please do the following.

docker rm  lb 

this will remove the previous container

next do a pull to get the new image

docker pull restcomm/load-balancer:latest

once the pull is completed try running the load balancer again as follows:

docker run --name=lb  restcomm/load-balancer:latest
