How do I install Dockerlings on a system without Go?

You must install Go first, as Dockerlings is built with Go and requires compilation. Follow the Go installation guide, then clone the repo and build it using the commands in the README.

Is Dockerlings better than the official Docker documentation for learning?

Dockerlings is more hands-on and interactive, ideal for practical exercises with immediate feedback, while official docs are comprehensive for reference. Use both for a balanced approach.

Can I add my own exercises to Dockerlings?

Yes, as an open-source project, you can fork the repository and contribute new exercises. Check the GitHub repo for guidelines or engage with the community on Discord.

How long does it take to complete all Dockerlings exercises?

With consistent practice, it typically takes a few hours to a day, depending on your prior knowledge. The exercises are progressive, so pace yourself for effective learning.

Dockerlings vs Katacoda: which is better for beginners?

Dockerlings is free, open-source, and terminal-based, great for offline learning, while Katacoda offers web-based labs with cloud environments. Choose based on preference for terminal vs. web interaction.

Does Dockerlings cover Docker Swarm or Kubernetes?

No, Dockerlings focuses on core Docker concepts like images, containers, volumes, networks, and Docker Compose. For orchestration tools, you'll need to seek additional resources or tutorials.

Pros & Cons

Pros

Interactive Terminal Interface

Offers a beautiful TUI built with Bubble Tea for seamless navigation and immediate feedback, enhancing engagement directly in the terminal as highlighted in the README.

Progressive Hands-on Curriculum

Includes over 15 exercises that build from basic container operations to advanced topics like multi-stage builds, ensuring gradual skill development as detailed in the exercise table.

Real-World Docker Concepts

Covers practical aspects such as volumes, networks, and Docker Compose, making it applicable to actual container workflows as emphasized in the 'Real-world skills' section.

Minimal Setup Overhead

Requires only cloning the repository and building with Go, allowing learners to start quickly with Docker installed, per the 'Zero friction' claim in the README.

Cons

Go Compilation Dependency

Users must have Go installed to build the tool, which adds an extra step compared to pre-packaged solutions and may deter those without Go expertise.

Limited to Provided Exercises

The curriculum is fixed and does not cover newer Docker features or advanced orchestration tools like Kubernetes, potentially restricting learning beyond the basics.

Terminal-Only Learning Experience

Lacks GUI elements or visual aids, which might not suit all learning styles or accessibility needs, limiting its appeal to visual learners.
