Putting the Pieces Together
A production-oriented Docker project combines a multi-stage application image, non-root execution, private internal networks, persistent database storage, health checks, environment-based configuration, image versioning, and automated builds.
The final goal is reproducibility: a new developer or deployment host should be able to build or pull the exact artifacts and start the required services with predictable behavior.
Suggested Architecture
- Nginx or another reverse proxy for public HTTP traffic.
- Application container on a private backend network.
- Database on the backend network with a persistent volume.
- Optional Redis cache on the backend network.
- Health checks for critical dependencies.
- Registry-backed immutable image releases.
