docker-compose-withDtAppMon.yml does not match Dynatrace-AppMon-Docker project

[mpvvliet]

I'm trying to get the dockerized version of AppMon to work with easyTravel-Docker as per the instructions. I've successfully setup Dynatrace-AppMon-Docker and can run it in docker.

Unfortunately, the command docker-compose -f docker-compose-withDtAppMon.yml up fails because the links to the AppMon docker setup (networks, volumes) do not match. I've tried porting the configuration file to v3 and fixing the links, but have been unable to get it working.

Any help would be much appreciated.

Thanks,
Martin

Here are the modifications I made to get the Composefile to interact with the Dynatrace Server from Dynatrace-AppMon-Docker. With these modifications, Easy Travel data is logged in Dynatrace. Hope it helps.

• External Network dynatracedocker_appmon (in my case this is the network created by the Dynatrace Server Compose stack).
• External Volume dynatracedocker_dthome (I modified Dynatrace Compose file to create Docker Volumes per the latest versions of Docker).
• Service names match host names and container names (otherwise I was getting getaddrinfo host not found errors.
