 and rebuilds and redeploys by itself. Otherwise, press **Pull and redeploy**

+Leave **Re-pull image** off, both on the stack and in the GitOps settings.
+The image (`saraview:server`) is only ever built on SpineS, so a re-pull
+looks for it on Docker Hub and fails with "pull access denied for
+saraview". The container's own **Recreate** button doesn't update SaraView
