Welcome to Container Harbour! 🚢 Ep.15

Episode 15: Leaving Harbour Gracefully 🌅 The Production Deployment That Used to Require a 2am Saturday Maintenance Window 😤 Every engineer who has been around long enough has a war story. Mine involves: A 2am Saturday maintenance window A 45-minute planned outage A deployment script that nobody had tested end-to-end A rollback that took longer than the deployment One very understanding on-call team Three energy drinks A fundamental reassessment of my life choices We took the service DOWN. We deployed. We brought it UP. Users couldn't access their accounts for 45 minutes. On a Saturday night. Because that's when "traffic was lowest." Today? Our deployments happen at 2pm on a Tuesday.
