May your pagers be silent and your PRs be merry 🎅🎄🎁🕎
Big thanks to @RobEarlam for the narration!

'Twas the dev before Christmas
And all through the App
Not a pager was buzzing
Not e’en a resource cap
The on-call schedule
was created with care
To avoid people’s flights
and know who’d be there
The metrics were green
For the year-end deploys
No pushes on Fridays
They make too much noise
Then one little hard drive
Filled with great logs
Raw JSON was dumped
From somebody’s blogs
A cascading failure,
as pods were evicted
Kublets unhealthy,
iptables conflicted
Pagerduty called
and Slack made a clatter
I opened my laptop
to see what was the matter
Dashboards were red
and graphs trended down
Crashloopback stated,
image not found
Starting my term,
I knew what to use
Familiar tools,
to face this bad news
Su basher, curl endpoints,
a for loop should do
Kube pipe to jq,
and sleep, deploy new
The nodes were replaced
with expanded disks
We’ll change them tomorrow,
with a permanent fix
Runbooks updated,
the Zoom call made right
Silent pagers to all,
and to all a good night!
