Docker 기초 실습

실습

실습1: 간단한 Hellow World 프로그램

Node.js로 구성된 웹 서비스를 작동해 봅니다.

 

실습 과정

1. 환경 설정
2. Dockerfile 생성
3. Docker Image 생성
4. Docker Container 실행

# app.js

console.log("Hello Docker!");

# Dockerfile

FROM node:alpine
COPY . /app
WORKDIR /app
CMD node app.js

# Docker Image

docker build -t hello-world-docker
docker image ls

# Docker Container

docker run hello-world-docker

# Docker Registry

docker tag hello-world-docker:latest yeeeeeeen/hello-world-docker:latest
docker login --username=yeeeeeeen		# password 필요
docker push yeeeeeeen/hello-world-docker

# Docker Hub

docker version
docker pull yeeeeeeen/hello-world-docker
docker image ls
docker run yeeeeeeen/hello-world-docker

실습2: Ubuntu 실행

Ubuntu를 Docker를 이용하여 실행해 봅니다.

docker run ubuntu
docker ps		# 실행 중인 목록
docker ps -a	# 실행이 끝난 것 포함한 목록
docker run -it ubuntu

• nano : editor
• apt list
• apt install
• apt update
• apt remove

 

실습3: MySQL 서버 실행

MySQL 8.0을 Docker를 이용하여 실행해 봅니다.

docker pull mysql/mysql-server:8.0
docker run --name=mysql_container mysql/mysql-server:8.0
docker logs mysql_container 2>&1 | grep GENERATED
docker exec -it mysql_container mysql -uroot -p
