Dockefile에 ADD를 이용하여 apache2 컨테이너를 실행해보자

ADD의 장점 copy, url, gz은 압축을 풀어서 컨테이너에 넣어준다

1.도커파일 생성

root@hostos1:~/DockerLabs/sed/webapp# vi Dockerfile

FROM ubuntu:14.04
MAINTAINER "ayk <yg1700@naver.com>"
LABEL "purpose"="webserver practice"

RUN apt-get update && apt-get install -y apache2 \
                                         vim \
                                         curl

ADD webapp.tar.gz /var/www/html
WORKDIR /var/www/html
EXPOSE 80

RUN sed -i 's|Docker Container Application by kevin.lee "hylee@dshub.cloud"|Docker Cont
ainer Application by ayk "yg1700@naver.com" |g' index.html

CMD /usr/sbin/apache2ctl -D FOREGROUND

2.빌드

root@hostos1:~/DockerLabs/sed/webapp# DOCKER_BUILDKIT=1 docker build -t myhttp:1.0 .
[+] Building 67.4s (10/10) FINISHED
 => [internal] load build definition from Dockerfile                               0.0s
 => => transferring dockerfile: 457B                                               0.0s
 => [internal] load .dockerignore                                                  0.0s

3.빌드 이미지 확인

root@hostos1:~/DockerLabs/sed/webapp# docker images | grep myhttp
myhttp                              1.0          91c00e4f207e   23 minutes ago      264MB

root@hostos1:~/DockerLabs/sed/webapp# docker image history myhttp:1.0
IMAGE          CREATED          CREATED BY                                      SIZE      COMMENT
91c00e4f207e   23 minutes ago   CMD ["/bin/sh" "-c" "/usr/sbin/apache2ctl -D…   0B        buildkit.dockerfile.v0
<missing>      23 minutes ago   RUN /bin/sh -c sed -i 's|Docker Container Ap…   731B      buildkit.dockerfile.v0
<missing>      23 minutes ago   EXPOSE map[80/tcp:{}]                           0B        buildkit.dockerfile.v0

4.실행

root@hostos1:~/DockerLabs/sed/webapp# docker run -d -p 8010:80 --name myhttp1 myhttp:1.0

5.확인

root@hostos1:~/DockerLabs/sed/webapp# docker exec -it myhttp1 bash
root@1cb3ecba3564:/var/www/html# apt-get -y install tree
	
root@1cb3ecba3564:/var/www/html# ls
css  index.html  pngs
root@1cb3ecba3564:/var/www/html# tree
.
|-- css
|   `-- bootstrap.css
|-- index.html
`-- pngs
    |-- docker.png
    `-- docker_logo.png

2 directories, 4 files

짜잔 정상적으로 apache2 컨테이너가 실행되고 있다
