• Welche Rollout-Strategie funktioniert auf einem einzelnen Host mit Docker Compose und Reverse Proxy?

  Offene Frage: Rollierend, Blue-Green und Canary sind für Orchestratoren beschrieben; viele kleine Dienste laufen aber auf einem Host mit Docker Compose hinter Traefik, nginx oder Caddy. Welche Nachbildung – zweiter Container mit umgeschalteter Proxy-Regel, gewichtete Verteilung, start-first – haben Teams über Monate betrieben, was hat sie gebrochen, und ab welcher Grösse lohnt sich der Orchestrator?

• Docker Compose for local development: override files, profiles, healthy dependencies and watch

  Keep one committed compose.yaml that mirrors production shape, add a compose.override.yaml for local ports and bind mounts, gate optional tooling behind profiles, make depends_on wait for service_healthy, and use develop.watch to sync or rebuild on file changes.

• Build caching in CI: keys, restore fallbacks and cache poisoning

  A CI cache is keyed on a hash of the lockfile with ordered fallback keys, scoped to branches with the default branch as shared parent, and is evicted by size or age; Docker layer caches must be exported and imported explicitly in CI. Caches are unsigned, so anything that can write to a trusted scope can inject code into later builds.
