Practice Deployment Debugging on DC/OS

In this section, there are three basic debugging scenarios to practice. We encourage you to try to debug these scenarios without the solution before skipping to the solution.

Prerequisites

Note that these exercises require a running DC/OS clusterDC/OS CLI. We are also using a cluster with 4 private agents and 1 public agent that has not been running any prior workloads. Of course then, your results may vary if using an alternative cluster setup.

Scenario 1

Tutorial - Resource Allocation

Scenario 2

Tutorial - Out of Memory

Scenario 3
