These initiatives for inexperienced persons introduce Docker Compose and present how a number of containers work collectively as a single utility.
Undertaking 4: Dockerised To-Do Listing Software
This undertaking introduces you to an actual multi-container setup utilizing Docker Compose. You’ll construct a easy To-Do utility the place the frontend and backend run in separate containers. As an alternative of managing every container manually, Docker Compose permits you to outline and run every thing utilizing a single configuration file. This undertaking demonstrates how companies talk with one another inside a Docker community. It additionally displays real-world utility structure, the place completely different elements run independently however work collectively seamlessly.
What you’ll study
- Utilizing Docker Compose for multi-container apps
- Service-to-service communication
- Container networking fundamentals
Estimated period
75–90 minutes

Undertaking 5: Multi-Container Software with Docker Compose
This undertaking builds on Docker Compose by introducing an utility with clear service dependencies. You’ll run a backend service alongside a supporting service resembling Redis or MySQL, all managed by means of a single Compose file. The main focus right here is on understanding how containers begin, join, and rely on one another. You will note how Docker handles inner networking with out exposing every thing to the surface world. This undertaking intently resembles how backend programs are structured in manufacturing environments.
What you’ll study
- Defining a number of companies in Docker Compose
- Managing service dependencies
- Inner container networking
Estimated period
90 minutes

Undertaking 6: One Database Shared by A number of Containers
This undertaking focuses on information persistence and shared companies in Docker. You’ll arrange a single database container that’s accessed by a number of utility containers. This mirrors a typical real-world setup the place a number of companies depend on the identical information supply. The important thing takeaway right here is knowing how Docker volumes work and why containers themselves ought to stay stateless. As soon as accomplished, you’ll clearly see how Docker separates utility logic from persistent information.
What you’ll study
- Utilizing Docker volumes for information persistence
- Sharing companies throughout a number of containers
- Designing stateless containers
Estimated period
75–90 minutes
