Bootstrapping Microservices, Second Edition: With Docker, Kubernetes, GitHub Actions, and Terraform
docker build is a Docker CLI command that constructs a Docker image from a build context and instructions.
- How it is used
- Packages a microservice as a Docker image before local execution, registry publication, or Kubernetes deployment.
- How deep it goes
- Explains command syntax, build context, tagging, cached layers, output, and deployment-oriented versioning without detailing Dockerfile instructions.
- Examples
- Uses Node.js video-streaming projects, Dockerfile-prod builds, image listings, and versioned registry-publishing commands.
- What you can do after
- Build it from scratch, inspect the resulting image, assign deployment versions, and prepare it for registry publication.
Spring in Action, Sixth Edition
docker build is a Docker command that constructs a container image from a Dockerfile and its build context.
- How it is used
- Builds a deployable container image from a Spring Boot application's Dockerfile and executable JAR.
- How deep it goes
- Explains Dockerfile instructions line by line and demonstrates tagged builds, without detailing Docker image internals.
- Examples
- Uses an OpenJDK 11 Dockerfile, a target/*.jar artifact, and a tagged Taco Cloud image build.
- What you can do after
- Builds a tagged Docker image from a Spring Boot project's Dockerfile and build context.

Data Pipelines with Apache Airflow, Second Edition
docker build is a Docker CLI command that constructs an image from a Dockerfile and its build context.
- How it is used
- Builds container images that package task code and dependencies for execution with Docker or DockerOperator.
- How deep it goes
- Explains Dockerfile instructions, build context, tagging, build output, and runtime testing, but does not detail advanced build configuration.
- Examples
- Uses weather-fetching and MovieLens ratings images, with tagged builds and docker run help checks.
- What you can do after
- Build it from scratch by writing a Dockerfile, supplying a context, tagging the image, and testing its packaged command.

Road to Kubernetes
docker build is a Docker command that constructs a container image from a Dockerfile and build context.
- How it is used
- Builds repeatable container images for running applications locally or preparing them for registry-based deployment.
- How deep it goes
- Explains Dockerfile-driven builds, runtime checks, registry tagging, and environment variants without detailing Docker’s internal build engine.
- Examples
- Demonstrates Node.js builds, runtime port and environment overrides, Docker Hub publishing, and development, staging, and production Dockerfiles.
- What you can do after
- Apply it via Docker to build tagged images, run them with configuration overrides, and prepare valid registry-bound artifacts.
