Mesos-DNS makes service discovery on an Apache Mesos cluster easy, but the instructions for setting up Mesos-DNS on the project site can result in a longer process than some people might prefer. Fortunately, there’s an option for setting up Mesos-DNS using a Docker image that makes it a much smoother process.
Setting up Mesos-DNS using the default method means actually building it from scratch using the Go programming language. For non-Golang developers, this may result in yak shaving as they spend time installing and learning Golang, Godep and other tooling only serves the purpose of setting up Mesos-DNS.
By contrast, the whole process can be done in under 5 minutes using the Docker method. This screencast walks through the process of installing and testing Mesos-DNS on an existing Mesos cluster, running on the Google Compute Platform. It will teach you:
- How to install Mesos-DNS via Docker
- How to configure the Mesos master and slave to use Mesos-DNS
- How to test and confirm the DNS configuration on the master and slave using dig via Docker
