OffOn Challenges

Welcome to OffOn Challenges! 🚀

These are hands-on, recurring prompts designed to help you practice Cloud Native, OpenTelemetry, AI/ML, and other open source skills.

Each challenge runs in a pre-provisioned environment, so you can focus on solving real problems, not setup headaches.

What makes these challenges special:

• 🎯 Skill-focused - Target specific technologies with clear objectives
• 📖 Story-driven - Learn through engaging narratives
• 🚀 Zero setup - Run in GitHub Codespaces, pre-configured and ready
• ✅ Two-step verification - Smoke tests and GitHub Actions validate your solution
• 🎓 Three levels - Beginner, Intermediate, and Expert for each adventure

💻 Run locally

The challenge environments can also be opened locally using VS Code Dev Containers.

Requirements

• Docker Desktop or another Docker-compatible runtime
• Visual Studio Code
• The Dev Containers extension: ms-vscode-remote.remote-containers
• Git

Start a challenge locally

1. Fork and clone this repository.
2. Open the repository folder in Visual Studio Code.
3. Open the Command Palette.
4. Select Dev Containers: Reopen in Container.
5. Choose the configuration for the adventure and difficulty level you want to run.
6. Wait for the container's postCreateCommand and postStartCommand to finish.

The container installs and starts the infrastructure required by the selected challenge.

Repository detection

In GitHub Codespaces, the repository is detected through the GITHUB_REPOSITORY environment variable.

When running locally, Adventure 01 derives the repository URL from the local origin Git remote. GitHub SSH remotes such as:

git@github.com:username/open-source-challenges.git
