Select an answer to reveal the explanation.
Short Explanation
Blue/green cutover at the front door means repointing the Ingress backend to the green Service. Flip the name, keep the port right, and leave blue around until you are sure.
Full Explanation
Blue/green often uses two Services. Cutting over HTTP traffic means updating the Ingress backend to reference the green Service name and port. Deleting green, ignoring the Ingress reference, or zeroing green before cutover undermines a controlled switch.
