수일 동안 Let’s Encrypt를 조정한 끝에, 복수의 포럼을 실행하는 데 관심이 있는 분들을 위해 정리했습니다.
1. 목적
아래와 같은 도메인이 있고 3개의 포럼을 운영하려는 상황을 가정합니다.
bbs.antivte.com
cp.antivte.com
ytb.antivte.com
2. Discourse 컨테이너
2.1 준비
서로 다른 포럼을 위해 3개의 app.yml 파일이 필요합니다. 이름은 bbs.yml, cp.yml, ytb.yml 등 원하는 대로 지정할 수 있습니다.
내용은 다음과 같아야 합니다.
참고: 외부 nginx와 백엔드 Discourse 컨테이너를 연결하기 위해 포트 80/443 리스닝 대신 유닉스 소켓을 사용하며, 백엔드 컨테이너의 SSL 설정도 제거합니다.
참고: 여기서는 포럼마다 하나의 컨테이너만 사용하며, 포럼별로 데이터 컨테이너와 웹 컨테이너를 분리하지 않습니다.
## this is the all-in-one, standalone Discourse Docker container template
##
## After making changes to this file, you MUST rebuild
## /var/discourse/launcher rebuild app
##
## BE *VERY* CAREFUL WHEN EDITING!
## YAML FILES ARE SUPER SUPER SENSITIVE TO MISTAKES IN WHITESPACE OR ALIGNMENT!
## visit http://www.yamllint.com/ to validate this file as needed
templates:
- "templates/postgres.template.yml"
- "templates/redis.template.yml"
- "templates/web.template.yml"
- "templates/web.ratelimited.template.yml"
## Uncomment these two lines if you wish to add Lets Encrypt (https)
# - "templates/web.ssl.template.yml"
# - "templates/web.letsencrypt.ssl.template.yml"
- "templates/web.socketed.template.yml" # <-- Added
## which TCP/IP ports should this container expose?
## If you want Discourse to share a port with another webserver like Apache or nginx,
## see https://meta.discourse.org/t/17247 for details
**#expose:**
**# - "8080:80" # http**
**# - "8443:443" # https**
params:
db_default_text_search_config: "pg_catalog.english"
## Set db_shared_buffers to a max of 25% of the total memory.
## will be set automatically by bootstrap based on detected RAM, or you can override
db_shared_buffers: "256MB"
## can improve sorting performance, but adds memory usage per-connection
#db_work_mem: "40MB"
## Which Git revision should this container use? (default: tests-passed)
#version: tests-passed
env:
LANG: en_US.UTF-8
# DISCOURSE_DEFAULT_LOCALE: en
## How many concurrent web requests are supported? Depends on memory and CPU cores.
## will be set automatically by bootstrap based on detected CPUs, or you can override
UNICORN_WORKERS: 4
## TODO: The domain name this Discourse instance will respond to
## Required. Discourse will not work with a bare IP number.
DISCOURSE_HOSTNAME: bbs.antivte.com
## Uncomment if you want the container to be started with the same
## hostname (-h option) as specified above (default "$hostname-$config")
#DOCKER_USE_HOSTNAME: true
## TODO: List of comma delimited emails that will be made admin and developer
## on initial signup example 'user1@example.com,user2@example.com'
DISCOURSE_DEVELOPER_EMAILS: 'techempower@163.com'
## TODO: The SMTP mail server used to validate new accounts and send notifications
# SMTP ADDRESS, username, and password are required
# WARNING the char '#' in SMTP password can cause problems!
DISCOURSE_SMTP_ADDRESS: smtp.mailgun.org
DISCOURSE_SMTP_PORT: 587
DISCOURSE_SMTP_USER_NAME: postmaster@mail.antivte.com
DISCOURSE_SMTP_PASSWORD: "67c9458eb7a6ff11b4db70f097b1b5c3-f7910792-0e7dbcc9"
#DISCOURSE_SMTP_ENABLE_START_TLS: true # (optional, default true)
## If you added the Lets Encrypt template, uncomment below to get a free SSL certificate
LETSENCRYPT_ACCOUNT_EMAIL: techempower@163.com
## The http or https CDN address for this Discourse instance (configured to pull)
## see https://meta.discourse.org/t/14857 for details
#DISCOURSE_CDN_URL: https://discourse-cdn.example.com

## Plugins go here
## see https://meta.discourse.org/t/19157 for details
hooks:
after_code:
- exec:
cd: $home/plugins
cmd:
- git clone https://github.com/discourse/docker_manager.git
- git clone https://github.com/procourse/procourse-installer
## Any custom commands to run after building
run:
- exec: echo "Beginning of custom commands"
## If you want to set the 'From' email address for your first registration, uncomment and change:
## After getting the first signup email, re-comment the line. It only needs to run once.
#- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
- exec: echo "End of custom commands"
2.2 설정
아래와 같은 설정 셸 스크립트를 준비합니다.
#!/usr/bin/env bash
./launcher bootstrap bbs
./launcher bootstrap test
./launcher bootstrap cp
./launcher bootstrap ytb
./launcher start bbs
./launcher start test
./launcher start cp
./launcher start ytb
이 스크립트를 이전에 사용했거나 각 컨테이너를 이미 한 번 실행한 적이 있다면, app.yml의 내용을 수정했다면 컨테이너에 적용하려면 다음 명령을 사용해야 합니다.
./launcher rebuild bbs
2.3 확인
3개의 컨테이너가 성공적으로 실행되고 있는지 확인하고 유닉스 소켓이 정상인지 점검합니다.

3. 외부 nginx
서버에 nginx/openresty를 설치하고 원하는 디렉토리에 nginx.conf 파일을 생성합니다. 디렉토리는 nginx 실행 명령에만 영향을 미치며, nginx.conf 내용은 다음과 같습니다.
여기서는 Cloudflare 인증서와 키를 호스트 디렉토리에 다음과 같이 배치했습니다.
3.1 nginx.conf
ssl_certificate /var/discourse/shared/ssl/antivte.com.cert.pem;
ssl_certificate_key /var/discourse/shared/ssl/antivte.com.key.pem;
향후 외부 nginx에서 Let’s Encrypt 자동 인증서와 키를 사용하는 방법을 알려드리겠습니다.

3.2 nginx 시작
nginx.conf 파일을 배치한 디렉토리로 이동하여 다음 명령을 실행합니다.
nginx -p `pwd`/ -c nginx.conf
4. 이제 원하는 결과를 얻을 수 있습니다.
축하합니다!
