Portainer's "Pull and redeploy" runs `compose pull` before `compose up`. With `image: kaiser-natron:portainer` set, that tries to pull the image from Docker Hub and fails with "pull access denied" because the image only exists as a local build artifact. `pull_policy: build` tells compose to skip the pull step for this service.

# Portainer stack — Kaiser Natron dev showcase.
|
|
#
|
|
# Flow:
|
|
# 1. Developer runs `npm run build` locally and commits the updated dist/.
|
|
# 2. Portainer → Stacks → Pull and redeploy.
|
|
# 3. The image is a tiny nginx with the prebuilt dist copied in.
|
|
#
|
|
# This is deliberately simple for a showcase box — no container-side npm,
|
|
# no hardening, no resource ceilings. Tighten when it graduates to prod.
