1. AWS EC2에서 Docker 실행하기

1) EC2 인스턴스 생성

os (flatform) : Amazon Linux
instance type : t2.micro
keypair : spartakeypair.pem
public IPv4 address : 3.34.44.xxx

2) Docker 설치

2-1) gitbash로 EC2 인스턴스에 접속하기

ssh -i {keypair_location} {user_name}@{public IPv4 address}

Amazon Linux의 기본 사용자 이름: ec2-user

2-2) Docker 설치

sudo yum update -y
sudo amazon-linux-extras install docker -y

2-3) Docker service 실행

sudo service docker start
service docker status

2-4) sudo 권한 없이 Docker 사용하기

sudo usermod -a -G docker ec2-user

명령어 입력 후 shell 재접속 해야함

2. Docker compose

: 여러개의 container들을 정의하고 실행하기 위한 도구

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.
- https://docs.docker.com/compose/

1) Docker compose 설치

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

2) yaml 파일 생성

vi docker-compose.yaml

version: "3.9"
services:
  flask:
    image: kimphysicsman/docker-memo:latest
    ports:
      - "80:5000"
  mongo:
    image: mongo:latest
    volumes:
      - mongo:/data/db/
    ports:
      - "27017:27017"

volumes:
  mongo:

3) docker compose 실행

docker-compose up -d
