This document provides an introduction to Docker and containerization. It covers: 1. The differences between virtual machines and containers, and the container lifecycle. 2. An overview of the Docker ecosystem tools. 3. Instructions for installing and using the Docker Engine and Docker CLI to build, run, and manage containers. 4. A demonstration of using Docker Hub to build and store container images. 5. An introduction to Docker networking and volumes. 6. A demonstration of using Docker Compose to define and run multi-container applications. 7. Suggestions for further learning resources about Docker.
![Dockerfile Reference
Same folder, docker build .
docker build -f /other/folder/file .
Add tag, docker build -t TAG_NAME .
Sample:
FROM debian:jessie
MAINTAINER docker "docker@nginx.com"
RUN apt-get update && apt-get install -y nginx
CMD ["nginx", "-g", "daemon off;"]
