buildah 기반의 컨테이너 생성

Buildah 명령어를 이용한 컨테이너 생성 절차.

Docker기반에서도 동일하게 컨테이너 생성 가능.

1. buildah 패키지 설치
   

   $> yum install buildah -y
   

2. 컨테이너 생성을 위한 Dockerfile 생성
   

   $> cat Dockerfile
   FROM docker.io/library/rockylinux
    
   RUN yum install tree httpd -y
   RUN mkdir -p /svc/http/
   COPY ./httpd.conf /svc/http/

3. buildah로 컨테이너 생성
   

   $>  buildah bud -t tree:1.0
   STEP 1/4: FROM docker.io/library/rockylinux
   STEP 2/4: RUN yum install tree -y
   ...
   STEP 3/4: RUN mkdir -p /svc/http/
   STEP 4/4: COPY ./httpd.conf /svc/http/
   COMMIT tree:1.0

4. 컨테이너 생성 여부 확인
   

   $> podman  image ls
   REPOSITORY                    TAG         IMAGE ID      CREATED         SIZE
   docker.io/library/rockylinux  latest      c830f8e8f82b  2 weeks ago   211 MB
   localhost/tree                1.0         a77e50505d7a  32 seconds ago  257 MB

5. 생성된 이미지 띄워서 dockerfile에 정의된 절차대로 작업 되었는지 확인
   

   $> podman run -dt localhost/tree:1.0
   c0b576f3bc807c98d1eb48c6f943c48cc43acae2c20b33d7851878ae6224c9cf
    
   $> podman  ps -a
   CONTAINER ID  IMAGE                                COMMAND      CREATED             STATUS            PORTS                                                                                                                                 NAMES
   c0b576f3bc80  localhost/tree:1.0                   /bin/bash    4 seconds ago       Up 4 seconds ago  dreamy_lamarr
    
   $> podman  exec -it dreamy_lamarr tree /svc/
   /svc/
   `-- http
       `-- httpd.conf
    
   1 directory, 1 file
