- Docker Build is more than a command for building images, and it's not only about packaging your code.
- In this post, let’s discus about docker run command and build command and their options.
- Once a Dockerfile is written, you can use the docker build command to generate a Docker image based on the Dockerfile’s instructions.
- The “docker build” command reads the Dockerfile, interprets the instructions, and executes them in order to build the image layer by layer.
- Docker build images by reading instructions from a Dockerfile.
- This article will explore the Docker build command, its syntax, usage, and the best practices to optimize your Docker builds.
- If you prepare a new Dockerfile, navigate to the same directory as said file and run the Docker build command to start a new image build process.
- We’ll now see a few examples of how you can use the docker build command in practice, using the example of a static site.
- Docker can build images automatically by reading the instructions given in a Dockerfile .
