30-Day Practice Plan

Week Focus Practice
1 Compose mastery Dockerize 3 personal projects
2 Kubernetes basics Deploy a Compose project to minikube
3 CI/CD Add GitHub Actions to build + push images
4 Cloud deployment Deploy to a managed K8s cluster

Keep Building

The best way to learn is to build real things:

  1. Dockerize your own projects — Every personal project should have a compose.yml
  2. Contribute to open source — Many projects need help with Docker setup
  3. Write about what you learn — Teaching reinforces understanding
  4. Join a community — Docker Slack, local meetups, conferences
