1、编辑配置文件

cd /var/discourse

git pull

nano containers/app.yml

添加after_web_config块hooks（缩进很重要用Notepad++）：

hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - mkdir -p plugins
          - git clone https://github.com/discourse/docker_manager.git
  after_web_config:
    - replace:
        filename: /etc/nginx/nginx.conf
        from: /sendfile.+on;/
        to: |
          server_names_hash_bucket_size 64;
          sendfile on;
    - file:
        path: /etc/nginx/conf.d/discourse_redirect_1.conf
        contents: |
          server {
            listen 80;
            server_name example.com;
            return 301 $scheme://talk.example.com$request_uri;
          }
    - file:
        path: /etc/nginx/conf.d/discourse_redirect_2.conf
        contents: |
          server {
            listen 80;
            server_name www.example.com;
            return 301 $scheme://talk.example.com$request_uri;
          }

您可以根据需要添加多个file块，具体取决于要重定向的域数。

2、重建容器

./launcher rebuild app
