Docker Build and Docker Engine

What is Docker Build?

The docker build command creates Docker images using a Dockerfile and a "context". The set of files in the supplied PATH or URL constitutes the build's context.

Docker Build Best Practices

• Choose the smallest base image (alpine images) possible.
• Reduce the amount of clutter in your images.
• Create multi-stage builds.
• Try to make images with common layers.
• Tagging with semantic versioning.
• Try not to install unneeded items or dependencies.
• Create a ".dockerignore" file to remove unnecessary things from the build context.

Docker Engine

The Docker engine, sometimes known as Docker, is a client-server application that creates and runs containers using Docker components. Runs on different Linux (CentOS, Debian, Fedora, Oracle Linux, RHEL, SUSE, and Ubuntu) and Windows Server OS.
