Why does changing the Deployment image from nginx:1.26-alpine to nginx:1.27-alpine start a rollout?
nginx:1.26-alpine
nginx:1.27-alpine
The image is part of the Pod template, and a template change creates a new Deployment revision and ReplicaSet.
The release-client Pod detects the new tag and starts the rollout.
Every image edit automatically doubles the Deployment replica count.
The image edit assigns a new address to the Service.
