GitHub:
GitHub is all about source code. It’s a platform where you can:
- Store and manage code: Think of it as a cloud-based version control system where you can track changes, manage branches, and collaborate on projects.
- Collaborate with others: GitHub makes it easy to work with other developers on the same codebase, review code, suggest changes, and handle issues.
- Version control: GitHub uses Git to track every version of your project. You can revert back to any previous version or see who made what changes when.
In short, GitHub is for managing the source code of your applications — it's all about the written code and project files.
Docker Hub:
Docker Hub, on the other hand, deals with container images — the packaged version of your application, complete with everything it needs to run, like:
- Operating system dependencies
- Software libraries or runtimes
- The app itself
Once your app is containerized in Docker (wrapped up in a neat little bundle), Docker Hub is where you can store, share, and manage these container images. It’s like a giant library of pre-built apps (images) that are ready to run.
In a nutshell:
- GitHub = Code
- Docker Hub = Packaged app (container image)
When to Use Which?
- Use GitHub when you're collaborating on writing code, need to manage branches, or want to keep track of how your code evolves over time.
- Use Docker Hub when your app is ready to run or share as a container and you want to store and manage the images, either publicly or privately.
Think of it like this: GitHub is for writing and organizing the ingredients (code), while Docker Hub is for sharing the fully-cooked meal (the containerized app)!
