THE OPSFORGED METHOD
Evidence before restart.
Deleting a pod can erase the evidence that explains why it failed. The playbook trains a durable incident habit: capture the signals, identify the layer, make the smallest safe change, and validate the recovery.
“Find the break. Prove the cause. Fix with confidence.”
Start with pod state, Events and restart history.
Preserve logs, manifests and the previous container exit.
Stop at the first layer where evidence fails.
Apply the safe fix and prove production health.
