What currently exists in this repository?

• Kafka: We don't use this at all (DHM 2019). I am told that we thought about using Kafka for a bit, but didn't end up going for it.
• TeamCity Agent: We have two agents (Windows and Linux). The team talked about making a separate image for each projects that needs to be built. While this could shrink the image size, it's not worth keeping up all the different containers

Reference: This is the link to an issue opened where the DNS was not being properly set in the teamcity-agent container
