Docker 컨테이너 구축 실습으로 docker 명령어 알아보기 (3): Portainer, 리눅스 알파인

<Portainer 컨테이너 구축>

1. 컨테이너 이미지 불러오기

ubuntu@host1:~/works$ docker pull portainer/portainer-ce
Using default tag: latest
latest: Pulling from portainer/portainer-ce

Status: Downloaded newer image for portainer/portainer-ce:latest
docker.io/portainer/portainer-ce:latest

 

2. 볼륨 생성 옵션을 이용해 컨테이너 생성

• 볼륨: Docker 컨테이너의 생명 주기와 관계없이 데이터를 영속적으로 저장

ubuntu@host1:~/works$ docker volume create portainer_data
portainer_data
ubuntu@host1:~/works$ docker volume ls
DRIVER    VOLUME NAME
local     3c6934ae8b00c0075ee164b4adf4db3efd685465b23936fbe61323800a1d100a
local     7218ff99f0ef01950ab25d481f4e099e049adf6c750e5c76cd9bf9b797ed465c
local     portainer_data

 

3. 컨테이너 접속

• -v: 볼륨 옵션
• —restart: 컨테이너가 죽어도 다시 재구동해

ubuntu@host1:~/works$ docker container run -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data --restart=always portainer/portainer-ce

<컨테이너 확인>

1. docker container ps: 상태 확인

ubuntu@host1:~/works$ docker container ps
CONTAINER ID   IMAGE                          COMMAND                   CREATED             STATUS             PORTS                                                           NAMES

2. 브라우저에서 접속 확인

 

< 리눅스 알파인 컨테이너 구축>

<컨테이너 생성 및 접속>

• —rm: 컨테이너가 종료되면 자동 삭제

ubuntu@host1:~/Labs/ch02$ docker container run -it --rm --name=linuxalpine alpine
Unable to find image 'alpine:latest' locally
latest: Pulling from library/alpine
661ff4d9561e: Pull complete

Status: Downloaded newer image for alpine:latest

 

<컨테이너 생성 (가동은 안되고 생성만 됨)>

• docker container create: 생성만 함

ubuntu@host1:~/Labs/ch02$ docker container create -it --name myalpine alpine
ubuntu@host1:~/Labs/ch02$ docker start myalpine
>> 하고 docker ps -a 하면 UP 상태 확인 가능 

>> 컨테이너로 들어가는 방법: docker container attach

ubuntu@host1:~/Labs/ch02$ docker container attach myalpine
/ # >> 접속 가능
