간단하게 컨테이너 빌드하기
Ubuntu 이미지 base에 apache, PHP를 연동하여 컨테이너를 빌드하시오.

$ cat Dockerfile
FROM ubuntu:18.04
ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update \
    && apt-get install -y apache2 \
    && apt-get install -y software-properties-common \
    && add-apt-repository ppa:ondrej/php \
    && apt-get update \
    && apt-get install -y php5.6

EXPOSE 80
CMD ["apachectl", "-DFOREGROUND"]


1. webserver 컨테이너 빌드하기
$ mkdir webserver
$ cd webserver


2. Dockerfile 생성
$ vim Dockerfile
FROM centos:7
RUN touch /etc/yum.repos.d/nginx.repo \
    && echo -e '[nginx]\nname=nage repo\nbaseurl=http://nginx.org/packages/centos/7/$basearch/\ngpgcheck=0\nenabled=1' > /etc/yum.repos.d/nginx.repo
RUN yum -y install nginx curl
CMD ["nginx", "-g", "daemon off;"]


3. 컨테이너 이미지 빌드
$ docker build -t myweb:20210622  .
...
Successfully tagged myweb:20210622


4. 빌드 된 컨테이너 이미지 확인
$ docker images
REPOSITORY   TAG        IMAGE ID       CREATED          SIZE
myweb        20210622   0bffae5d2f31   38 seconds ago   335MB


5. 생성된 컨테이너 이미지를 이용해 웹서버 동작 시키기
$ docker run -d --name webserver myweb:20210622
$ curl 172.17.0.2


6. 컨테이너 삭제하기
$ docker ps
ce0a4f2504bf   myweb:20210622   "nginx -g 'daemon of…"   About a minute ago   Up About a minute             webserver

$ docker rm -f webserver
webserver


1. nodejs 애플리케이션 컨테이너 빌드하기
$ mkdir appjs
$ cd appjs/
$ cat > app.js
const http = require('http');
const os = require('os');
console.log("Test server starting…");
var handler = function(req, res) {
  res.writeHead(200);
  res.end("Container Hostname: " + os.hostname() + "\n");
};
var www = http.createServer(handler);
www.listen(8080);


$ cat > Dockerfile
FROM node:12
COPY app.js /app.js
ENTRYPOINT ["node", "app.js"]


2. 컨테이너 빌드
$ docker build -t appjs .


3. 빌드 된 컨테이너 확인
$ docker images
REPOSITORY   TAG        IMAGE ID       CREATED          SIZE
appjs        latest     12cfd448b8eb   21 seconds ago   918MB


4. 빌드한 컨테이너 실행해보기
$ docker run -d --name appjs appjs
$ docker ps
CONTAINER ID   IMAGE     COMMAND         CREATED         STATUS         PORTS     NAMES
be999811a5d6   appjs     "node app.js"   5 seconds ago   Up 4 seconds             appjs

$ curl 172.17.0.2:8080
Container Hostname: be999811a5d6


5. 실행되었던 컨테이너를 종료하자.
$ docker rm -f appjs
