[Ubuntu] docker 및 docker compose 설치하기

AWS EC2에 만든 ubuntu서버에 docker 및 docker compose를 설치해보겠습니다.

 

먼저 생성한 ec2에 연결합니다.

> ssh -i "***.pem" ubuntu@ec2-***.ap-northeast-2.compute.amazonaws.com
The authenticity of host '***.ap-northeast-2.compute.amazonaws.com (xx.xxx.x.xxx)' can't be established.
ECDSA key fingerprint is SHA256:PcvcASLF420AQzOU5mzhCdy6D8OMMORUd29bpT6w0a8.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'ec2-***.ap-northeast-2.compute.amazonaws.com,xx.xxx.x.xxx' (ECDSA) to the list of known hosts.
Welcome to Ubuntu 22.04 LTS (GNU/Linux 5.15.0-1004-aws x86_64)

apt 패키지 index를 업데이트하고 https를 통해 repository를 이용하기 위해 다음과 같이 설치합니다.

ubuntu@ip-:~$ sudo apt-get install -y ca-certificates \
    curl \
    software-properties-common \
    apt-transport-https \
    gnupg \
    lsb-release

docker의 official GPG key를 등록합니다.

 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

stable repository를 등록합니다.

ubuntu@ip-:~$  echo \

  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

 

sudo apt-get install docker-ce docker-ce-cli containerd.io 명령어로 docker Engine을 설치합니다.

ubuntu@ip-:~$ sudo apt-get install docker-ce docker-ce-cli containerd.io

Running kernel seems to be up-to-date.

No services need to be restarted.

No containers need to be restarted.

No user sessions are running outdated binaries.

No VM guests are running outdated hypervisor (qemu) binaries on this host.

 

설치 완료 후 docker --version으로 버전을 확인합니다.

ubuntu@ip-:~$ docker --version
Docker version 20.10.16, build aa7e414

 

다음으로 docker compose를 설치합니다.

docker compose는 docker설치 시 함께 설치되지 않으므로 별도로 설치해주어야 하며, 여러 개의 도커 애플리케이션 컨테이너들을 정의하고 실행할 수 있도록 해줍니다. yaml파일을 사용하여 서비스를 설정하고 하나의 커맨드만으로 여러 개의 도커 컨테이너들을 사용할 수 있습니다.

ubuntu@ip-:~$ sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

실행 권한을 부여합니다.

ubuntu@ip-:~$ sudo chmod +x /usr/local/bin/docker-compose

 

docker compose 또한 docker-compse --version 명령을 통해 잘 설치되었는지 확인해봅니다.

ubuntu@ip-:~$ docker-compose --version
docker-compose version 1.29.2, build 5becea4c
