What is a Dockerfile

A Dockerfile is essentially a written guide. It’s a text file filled with all the instructions you might type into your command line to create an image. It’s like a recipe for baking the perfect digital cake!

How to create a Dockerfile

Creating a Dockerfile is straightforward! Just follow these steps:
Open a text editor of your choice.
Define your base image using the FROM keyword. For example, you might start with a base image like ubuntu or alpine.
Specify any environment variables using the ENV keyword. For example, ENV PATH /usr/local/bin:$PATH.
Run any commands necessary to set up your image using the RUN keyword. For instance, RUN apt-get update && apt-get install -y curl.
Add any necessary files to the image using the ADD or COPY keyword.
Define the command that should be executed when a container is run from your image using the CMD or ENTRYPOINT keyword.
Here’s a simple example:
FROM ubuntu:18.04 RUN apt-get update && apt-get install -y curl CMD ["/bin/bash"]
Remember, each command creates a new layer in the image, and you should strive to minimize the number of layers in your image to keep it small and efficient.
