Description:
In this video, you will learn about Dockerfiles, which are text files that contain instructions for building Docker images. Dockerfiles are essential for building repeatable and consistent Docker images.
What is a Dockerfile?
A Dockerfile is a text file that contains a set of instructions that Docker uses to build a Docker image. The instructions in a Dockerfile are executed in order, and each instruction can add a new layer to the image.
What are the benefits of using Dockerfiles?
There are many benefits to using Dockerfiles, including:
Repeatability: Dockerfiles ensure that Docker images are built in a consistent and repeatable way.
Consistency: Dockerfiles help to ensure that Docker images are consistent across different environments.
Version control: Dockerfiles can be stored in version control systems, which allows you to track changes and revert to previous versions.
Documentation: Dockerfiles can serve as documentation for your Docker images.
What are the parts of a Dockerfile?
A Dockerfile consists of a series of instructions, each of which starts with a keyword. The most common Dockerfile instructions include:
