1.docker-compose 다운

sudo apt install docker-compose

2.Nginx spring.conf(/nginx/conf.d/spring.conf) 작성

upstream app{
        server docker_gradle:8081;
}
server {
        listen       80;
        server_name  [domain];

        #access_log  /var/log/nginx/host.access.log  main;


        location /.well-known/acme-challenge/ {
                root /var/www/certbot;
        }

        location / {
                proxy_pass http://app;
        }

}

upstream: server 설정에서 Nginx 받아들인 요청을 어떤 서버로 흘려보내 줄 것인지 결정할 때 사용된다.

listen:포트 번호를 설정한다.

proxy_pass:정해진 pass로 요청을 전달한다.

3.docker-compose.yml 작성

version: '3'
services:
  docker_gradle:
    container_name: docker_gradle
    image: docker_gradle
    ports:
      - "8081:8081"
  nginx:
    container_name: nginx-server
    image: nginx
    ports:
      - "80:80"
      - "443:443"
    environment:
      TZ: "Asia/Seoul"
    volumes:
      - ./nginx/conf.d:/etc/nginx/conf.d
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/log:/var/log/nginx
      - ./data/certbot/conf:/etc/letsencrypt
      - ./data/certbot/www:/var/www/certbot
    depends_on:
      - docker_gradle
  certbot:
    container_name: certbot-server
    image: certbot/certbot
    restart: unless-stopped
    volumes:
      - ./data/certbot/conf:/etc/letsencrypt
      - ./data/certbot/www:/var/www/certbot
    depends_on:
      - nginx

services: docker_gradle(spring-server)와 nginx(nginx-server)로 나뉜다.

container_name:docker에 올라갈 container_name을 설정한다.

image:container에 쓰일 image를 선택한다.

ports: 외부접속포트와 docker내부 container의 포트를 설정하고 외부와 통신이 가능합니다.

volumes:docker volume들을 설정한다.

depends_on:container의 실행 순서를 정한다.(위의 yml 파일에서는 docker_gradle container가 먼저 올라가고 nginx서버가 올라간다.)

TZ: TimeZone 설정

4.docker compose 실행

# docker compose 실행
docker compose up -d

#실행 중인 컨테이너 확인
docker ps

docker compose를 실행하고 실행 중인 컨테이너를 확인 해 3개의 컨테이너가 정상적으로 작동되는지 확인합니다.

5.인증서 발급 스크립트 생성

# 인증서 발급 스크립트 생성
vim init-letsencrypt.sh

#!/bin/bash

if ! [ -x "$(command -v docker-compose)" ]; then
  echo 'Error: docker-compose is not installed.' >&2
  exit 1
fi

domains=([domain] www.[domain])
rsa_key_size=4096
data_path="./data/certbot"
email="[email]" # Adding a valid address is strongly recommended
staging=0 # Set to 1 if you're testing your setup to avoid hitting request limits

if [ -d "$data_path" ]; then
  read -p "Existing data found for $domains. Continue and replace existing certificate? (y/N) " decision
  if [ "$decision" != "Y" ] && [ "$decision" != "y" ]; then
    exit
  fi
fi


if [ ! -e "$data_path/conf/options-ssl-nginx.conf" ] || [ ! -e "$data_path/conf/ssl-dhparams.pem" ]; then
  echo "### Downloading recommended TLS parameters ..."
  mkdir -p "$data_path/conf"
  curl -s https://raw.githubusercontent.com/certbot/certbot/master/certbot-nginx/certbot_nginx/_internal/tls_configs/options-ssl-nginx.conf > "$data_path/conf/options-ssl-nginx.conf"
  curl -s https://raw.githubusercontent.com/certbot/certbot/master/certbot/certbot/ssl-dhparams.pem > "$data_path/conf/ssl-dhparams.pem"
  echo
fi

echo "### Creating dummy certificate for $domains ..."
path="/etc/letsencrypt/live/$domains"
mkdir -p "$data_path/conf/live/$domains"
docker-compose run --rm --entrypoint "\
  openssl req -x509 -nodes -newkey rsa:$rsa_key_size -days 1\
    -keyout '$path/privkey.pem' \
    -out '$path/fullchain.pem' \
    -subj '/CN=localhost'" certbot
echo


echo "### Starting nginx ..."
docker-compose up --force-recreate -d nginx
echo

echo "### Deleting dummy certificate for $domains ..."
docker-compose run --rm --entrypoint "\
  rm -Rf /etc/letsencrypt/live/$domains && \
  rm -Rf /etc/letsencrypt/archive/$domains && \
  rm -Rf /etc/letsencrypt/renewal/$domains.conf" certbot
echo


echo "### Requesting Let's Encrypt certificate for $domains ..."
#Join $domains to -d args
domain_args=""
for domain in "${domains[@]}"; do
  domain_args="$domain_args -d $domain"
done

# Select appropriate email arg
case "$email" in
  "") email_arg="--register-unsafely-without-email" ;;
  *) email_arg="--email $email" ;;
esac

# Enable staging mode if needed
if [ $staging != "0" ]; then staging_arg="--staging"; fi

docker-compose run --rm --entrypoint "\
  certbot certonly --webroot -w /var/www/certbot \
    $staging_arg \
    $email_arg \
    $domain_args \
    --rsa-key-size $rsa_key_size \
    --agree-tos \
    --force-renewal" certbot
echo

echo "### Reloading nginx ..."
docker-compose exec nginx nginx -s reload

docker-compose.yml이 있는 디렉토리에 인증서발급 스크립트를 생성합니다.

위의 스크립트에서 [domain].[email]에 사용 할 domain과 email을 입력하고 저장합니다.

6. 인증서 발급 스크립트 실행

sudo bash init-letsencrypt.sh

인증서 발급 스크립트를 실행하여 SSL인증서를 발급해줍니다.

7. spring.conf https 설정

upstream app{
        server docker_gradle:8081;
}
server {
        listen       80;
        server_name  [domain];

        #access_log  /var/log/nginx/host.access.log  main;


        location /.well-known/acme-challenge/ {
                root /var/www/certbot;
        }

        location / {
                return 301 https://$host$request_uri; #http접속시 https로 redirect
        }

}
server {
        listen 443 ssl;
        server_name [domain];
        server_tokens off; #nginx 버전 숨김

        ssl_certificate /etc/letsencrypt/live/[domain]/fullchain.pem; # SSL/TLS 인증서 경로
        ssl_certificate_key /etc/letsencrypt/live/[domain]/privkey.pem; # SSL/TLS 개인 키 경로
        include /etc/letsencrypt/options-ssl-nginx.conf; # Let's Encrypt에서 제공하는 Nginx SSL 옵션
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;        
        
        
        
        
        location / {
                proxy_pass http://app;
                proxy_set_header Host $http_host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

}

2번에서 만든 spring.conf파일에 https 설정을 추가해줍니다.

8. 인증서 자동갱신 command 추가

version: '3'
services:
  docker_gradle:
    container_name: docker_gradle
    image: docker_gradle
    ports:
      - "8081:8081"
  nginx:
    container_name: nginx-server
    image: nginx
    ports:
      - "80:80"
      - "443:443"
    environment:
      TZ: "Asia/Seoul"
    volumes:
      - ./nginx/conf.d:/etc/nginx/conf.d
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/log:/var/log/nginx
      - ./data/certbot/conf:/etc/letsencrypt
      - ./data/certbot/www:/var/www/certbot
    depends_on:
      - docker_gradle
    command: '/bin/sh -c ''while :; do sleep 6h & wait $${!}; nginx -s reload; done & nginx -g "daemon off;"'''
  certbot:
    container_name: certbot-server
    image: certbot/certbot
    restart: unless-stopped
    volumes:
       - ./data/certbot/conf:/etc/letsencrypt
       - ./data/certbot/www:/var/www/certbot
    depends_on:
       - nginx
    entrypoint: "/bin/sh -c 'trap exit TERM; while :; do certbot renew; sleep 12h & wait $${!}; done;'"

9.https 확인

# docker compose 실행
docker compose up -d

http로 들어가 https로 redirect가 되는 것을 확인하고 https로 연결되어있는지 확인합니다.
