Ugly Command Party - Day 4

On the 4th of the ugly command party, the command I'll share is:

Ugly Command Name: Fetch Ingress Object Health in Namespace

What does it do?

Looks through every Ingress object in a namespace and:

• Checks if it has a valid service/port
• Checks if pods & endpoints exist behind the service
• Declares if it’s Healthy (by having Endpoints) or Unhealthy (lacking endpoints)

When would you use it?

If you’re struggling with an ingress coming up, or have a lot of ingress objects to audit in a namespace, it’s a quick way to get a list of what has a valid configuration and what doesn’t from the Ingress through to the pod.

What is the command?

Please view the GitHub Gist below to find the code snippet. Due to a limitation with LinkedIn, it does not accept some code in the code snippet and breaks the Article feature :-/

What is some sample output?

Ingress: failed
