Checkout Pods Never Start

Ten minutes after tonight's release, the checkout Deployment has 0 of 2 replicas available and neither pod has ever started.

Stage 1 of 5 in Kubernetes Night Shift.

Briefing

First page of the night shift: the checkout release went out ten minutes ago and neither new pod has started.

Checkout was deployed into this namespace from scratch tonight, so there is no earlier revision to fall back on.

The release ticket names the approved build, and the registry team finished a mirror migration this afternoon.

Sam is fairly sure the migration broke registry credentials and is ready to start rotating the pull secret.

The fix is yours to find: hints, the recovery checks and the debrief unlock inside the incident.

How it plays

  1. 01

    Get paged

    The alert fires and the clock starts. Read the page and the briefing.

  2. 02

    Investigate

    Work in a simulated shell with realistic output: logs, configs, services.

  3. 03

    Fix it

    Change the system the way you would in production. Hints are there if you get stuck.

  4. 04

    Prove it

    Automated checks verify the recovery, then the debrief explains what happened.
