Update Docker images and add healthcheck#69
Merged
Conversation
Summary for .devcontainer/docker-compose.yml: Added startup coordination so the app waits for Postgres to become healthy and Redis to start. Added a Postgres healthcheck using pg_isready to improve container readiness detection. Pinned Postgres from latest to postgres:17 for a more stable, reproducible dev environment. Pinned Redis to redis:7-alpine, which is a smaller, versioned image and can improve image pull time. Removed the obsolete top-level Compose version field to align with modern Docker Compose conventions. Kept the original network_mode: service:db behavior, so the app’s networking model is unchanged.
