What is docker build env and what are its benefits
Docker build env is a collection of tools that provides a command line interface for manipulating Docker files and images. It includes functionality to help in developing, testing, and deploying software. It provides an interface to manage the state of your container and changes to images, which include:
– modifying container configurations
– updating the contents of a container to a newer version, or deleting an image and re-creating it with different content
– creating a new container from an existing image
Docker build env is not just a tool to modify images; it also takes snapshots of a container so that any changes made to the container do not affect its existing state or the state of any images.

Examples of how docker build env can be used in different workflows
In the following examples, I will show you how docker build env can be used in different workflow. They are not meant to be exhaustive but illustrate key concepts: a) docker build, b) syntax for building a single file, c) linking build artifacts to a container image, d) editing files and make CLI changes from within the container.
The “docker build” command is used to generate an image from one or more specified source files. It starts by taking the content of your source directory and rsyncing it into the Dockerfile located in your current working directory.
At this point, it will execute “CMD” and “ENTRYPOINT” so that the build context is properly set up:
# docker build .
