Challenge

Create a Falco Rules File Configured to Scan the Container
The container in question is running inside a Pod called nginx in the default namespace. The container is also called nginx. For this exercise, you can assume that the container name is unique in the cluster.

Create a Falco rules file at /home/cloud_user/nginx-rules.yml with a rule to report any newly-spawned processes in this container.

The rule's output should include the following:
- timestamp
- process name
- UID
- container ID
- container name
- container image name
Challenge

Run Falco to Obtain a Report of the Activity and Save It to a File

Falco is already installed on the worker node. Using your rules file, run Falco for 45 seconds or so to obtain a report of the container's activity.

Save the report to /home/cloud_user/falco-report.log.
