TO: Engineering All<\/strong>
\nFROM: Senior SRE (On-Call Rotation 4)<\/strong>
\nDATE: 04:12 AM – Day 3 of Incident #8842<\/strong>
\nSUBJECT: The Corpse of the Production Cluster and the Myth of Automation<\/strong><\/p>\n

It\u2019s 4:12 AM. I haven\u2019t slept since Tuesday. My vision is tunneling, and the blue light from my third monitor is starting to feel like a physical weight on my retinas. If you\u2019re reading this, the prod-us-east-1<\/code> cluster is technically “up,” but don’t mistake uptime for health. It\u2019s a shambling zombie held together by duct tape, shell scripts, and my own dwindling sanity.<\/p>\n

We were told that kubernetes orchestration<\/strong> would solve our scaling problems. We were told it was “self-healing.” Well, I\u2019ve spent the last 72 hours watching it “self-heal” us into a recursive death spiral that nearly wiped our entire stateful set. <\/p>\n

This is the reality of our stack. It\u2019s not a “solution.” It\u2019s a high-maintenance engine that demands blood.<\/p>\n

$ kubectl get pods -n prod-checkout\nNAME                                      READY   STATUS             RESTARTS      AGE\ncheckout-api-7f8d9465b-2v9sq             0\/1     CrashLoopBackOff   42 (5m ago)   3h12m\ncheckout-api-7f8d9465b-8n2px             0\/1     Terminating        0             14m\ncheckout-api-7f8d9465b-9lkkj             0\/1     Pending            0             2m\ncheckout-api-7f8d9465b-m4rtz             0\/1     ImagePullBackOff   0             8m\ncheckout-db-0                            0\/1     Pending            0             48h\n<\/code><\/pre>\n
Look at that. That\u2019s the heartbeat of our company. A CrashLoopBackOff<\/code> followed by a Pending<\/code> state that\u2019s been sitting there for two days because the scheduler has decided that our nodes\u2014despite having 64GB of RAM free\u2014don’t meet the “affinity requirements.” <\/p>\n
Welcome to the machine.<\/p>\n
