Question

Operators start a rolling update on a Deployment while also adding a separate canary Deployment for the same release, and the plan becomes unclear. What guidance applies?

Accepted Answer

Keep one clear strategy per release change—rolling, canary, or blue/green—not an undefined hybrid. — Pick a lane: rolling, canary, or blue/green—don’t drive all three at once. Mixed half-plans confuse who owns traffic and how to roll back. Clarity beats clever hybrids.

Answer

Always combine rolling, canary, and blue/green in one change for safety.

Answer

Prefer undefined hybrids because Kubernetes merges strategies automatically.

Answer

Disable the Deployment controller until both strategies finish.
