Understanding and installing Docker
Before installing Docker, we need to understand its value and purpose.
Docker is like a shipping container for your software. It packages everything your application needs to run – the code, libraries, and settings – and bundles them together. This ensures your application runs everywhere, in any OS without any issues. It guarantees that if the application works locally, it will work globally.
Docker guarantees your application runs exactly how you built it, every time. No more surprises due to different computer setups.
The main concepts in Docker are images and containers. Containers are lightweight and start up quickly, making testing and development cycles much smoother. You can simply ship the Docker container to any environment, cloud-based or not, and be confident it will work. Containers share the underlying OS, so you can run more applications on a single machine without bogging it down.
