As a developer, inform me should you relate to this – Docker instructions are simple to grasp however tough to use meaningfully. Out of the numerous tutorials that I adopted, most stopped at syntax, leaving me not sure about what to construct subsequent. (Right here is an exception – A step-by-step Docker tutorial for full learners) As an answer, I made a decision to strive my hand at real-life Docker tasks, meant to provide learners like me a style of the platform. I rapidly discovered that the quickest solution to perceive containers, pictures, networking, and Docker Compose is to construct small however sensible tasks that replicate actual utilization. With out hands-on tasks, Docker stays theoretical, regardless of what number of instructions you memorise.
On this article, I’ve tried to curate ten beginner-friendly Docker tasks which can be easy to begin but spectacular sufficient to showcase actual expertise. Every mission focuses on a particular Docker idea and builds confidence step-by-step. These tasks should not random demos; they’re structured, sensible, and supreme for anybody seeking to strengthen their Docker fundamentals by hands-on studying.
So with none additional ado, listed below are the ten beginner-friendly Docker tasks you possibly can strive your arms on at this time.

Mission 3: Easy Internet Server in Docker
This mission focuses on operating a fundamental net server totally inside a Docker container. You’ll use a prebuilt server picture, configure it utilizing Docker directions, and expose it to your native machine. The objective is to grasp how Docker handles processes, ports, and runtime instructions. In contrast to static internet hosting, this mission introduces server configuration and container execution circulate. It provides you a transparent view of how functions truly begin and run inside containers, which is a important idea earlier than shifting to multi-container setups.
What you’ll be taught
- Utilizing official Docker base pictures
- Understanding CMD and ENTRYPOINT
- Managing container lifecycle and ports
Estimated length
45–60 minutes

Class 2: Multi-Container Functions
These tasks for learners introduce Docker Compose and present how a number of containers work collectively as a single software.
Mission 4: Dockerised To-Do Checklist Software
This mission introduces you to an actual multi-container setup utilizing Docker Compose. You’ll construct a easy To-Do software the place the frontend and backend run in separate containers. As a substitute of managing every container manually, Docker Compose means that you can outline and run every thing utilizing a single configuration file. This mission demonstrates how providers talk with one another inside a Docker community. It additionally displays real-world software structure, the place completely different parts run independently however work collectively seamlessly.
What you’ll be taught
- Utilizing Docker Compose for multi-container apps
- Service-to-service communication
- Container networking fundamentals
Estimated length
75–90 minutes

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

Mission 6: One Database Shared by A number of Containers
This mission focuses on information persistence and shared providers in Docker. You’ll arrange a single database container that’s accessed by a number of software containers. This mirrors a standard real-world setup the place a number of providers 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 software logic from persistent information.
What you’ll be taught
- Utilizing Docker volumes for information persistence
- Sharing providers throughout a number of containers
- Designing stateless containers
Estimated length
75–90 minutes

Class 3: Actual-World App Deployments
These beginner-friendly tasks present how Docker is used to deploy well-liked, production-style functions.
Mission 7: Dockerised WordPress Web site
This mission introduces you to deploying a extensively used, real-world software utilizing Docker. You’ll run WordPress alongside a database container utilizing Docker Compose. As a substitute of manually configuring servers, Docker handles the whole setup by containers. This mission intently mirrors what number of small companies and manufacturing groups deploy content material administration programs at this time. It additionally reinforces the concept Docker isn’t just for builders, however for operating full functions reliably throughout environments.
What you’ll be taught
