Docker 실습 :: 제작한 이미지를 Github에 배포하고 가져오기

<이미지 제작 및 Github 업로드>

• 이미지: 내가 수정한 엔진엑스

1. Dockerfile 생성

FROM nginx:1.25.3-alpine3.18-slim
COPY index.html /usr/share/nginx/html/index.html
COPY cat.jpg /usr/share/nginx/html/cat.jpg
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

 

>> 깃허브에 repository 제작 > Dockerfile, index.html, cat.jpg 업로드

 

<Github에서 이미지 가져오기>

1. 이미지 가져오기

• git clone

**ubuntu@host1:~/works$ git clone <https://github.com/mogamjadori/mywebserver1.git**>
'mywebserver1'에 복제합니다...

2. 이미지 생성

4. 컨테이너 생성

**ubuntu@host1:~/works$ docekr container run -d -o 8003:30 --name=my-webserver2 myweb:2.0**
