minor · >=20.10.0 · published · verified 2026-09-08 `docker stack deploy` prints "Ignoring unsupported options: build" and deploys the previous image. Swarm never builds. Build the image yourself, push it to a registry the nodes can reach, and reference it by tag in the stack file. The warning goes to stdout and the deploy still reports success, so a CI job that only checks the exit code will happily ship a stale image. evidence |
