2. 해결방법

 

sudo docker images

위 명령어를 쳐서 살펴보면..

 

> sudo docker images
REPOSITORY         TAG         IMAGE ID       CREATED             SIZE
front              1.0         1f4a727b6b17   About an hour ago   144MB
ddd/node-web-app   latest      c53ceb5f0591   3 hours ago         115MB
backend            latest      c53ceb5f0591   3 hours ago         115MB

httpd              2.4         b9bd7e513e0f   3 days ago          144MB
httpd              latest      b9bd7e513e0f   3 days ago          144MB

이미지에 대한 내용들이 나온다.

 

그럼 docker-compose.yml로 다시 돌아와서 보면

 

version: "3.0"

services:
  apache:
    image: front:1.1
    restart: 'always'
    ports:
      - "80:80"
    container_name: frontend

  node:
    image: backend
    restart: 'always'
    ports:
      - "3334:80"
    container_name: backend

여기서 docker-compose.yml을 수정해야한다.

 

수정할 부분은 front:1.1 이다.

 

docker image에 보면 Tag 부분에 1.0을 붙여놨었기 때문에 front:1.1 이 아닌 front:1.0을 써주어야 한다.

 

마찬가지로 node : image : backend 부분에서는 tag를 안붙여놨기 때문에 그냥 써주어도 된다.

 

즉, image에는 레파지토리 이름과 테그가 빌드한 이미지와 같아야 한다.

 

수정하고 다시 실행해보면

> sudo docker-compose up
Starting frontend ... done
Starting backend  ... done
Attaching to frontend, backend

backend   | Example app listening at http://localhost:80

잘 실행되는 것을 볼 수 있다.
