What is the difference between a Docker image and a container?
A Docker image is a lightweight, standalone, executable package that includes everything needed to run a piece of software, while a container is a running instance of that image.
Can you explain how images and containers are related?
Sure! An image serves as a blueprint for creating containers. When you run an image, it creates a container that executes the software defined in that image.
Are images immutable while containers are mutable?
Yes, that's correct! Images are immutable, meaning they don't change once created, while containers can be modified during their runtime.
How do I create a Docker image?
You can create a Docker image using a Dockerfile, which contains instructions on how to build the image. Then, use the command docker build
to create it.
