Sourcegraph

暂时用systemd来管理Docker service。因为我们要用Nginx来做反代，所有端口都监听本地即可。

[Unit]
Description=Sourcegraph
Requires=docker.service
Conflicts=systemd-resolved.service,dnsdist.service

[Service]
ExecStart=/usr/bin/docker run --name=sourcegraph --publish 127.0.0.1:7080:7080 --publish 127.0.0.1:2633:2633 --rm --volume /etc/sourcegraph:/etc/sourcegraph --volume /var/lib/sourcegraph/data:/var/opt/sourcegraph sourcegraph/server:3.3.5
ExecStop=/usr/bin/docker stop sourcegraph
ExecReload=/usr/bin/docker restart sourcegraph
TimeoutStartSec=infinity

[Install]
WantedBy=multi-user.target

Nginx SSL卸载

证书签发的问题就不细讲了，以certbot自动签发为例。涉及的文件参见oh-my-nginx。

# 主站
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name sourcegraph.example.com;

    ssl_certificate     /etc/letsencrypt/live/sourcegraph.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/sourcegraph.example.com/privkey.pem;

    location / {
        proxy_pass http://127.0.0.1:7080;
        include conf.d/templates/proxy-default.conf;
        include conf.d/templates/transparent-proxy.conf;
    }

    include conf.d/templates/ssl.conf;
    include conf.d/templates/performance.conf;
    include conf.d/templates/security.conf;
}

# 管理控制台
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name sourcegraph-mgmt-console.example.com;

    ssl_certificate     /etc/letsencrypt/live/sourcegraph-mgmt-console.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/sourcegraph-mgmt-console.example.com/privkey.pem;
    
    location / {
        proxy_pass https://127.0.0.1:2633;
        include conf.d/templates/proxy-default.conf;
        include conf.d/templates/transparent-proxy.conf;
    }

    include conf.d/templates/ssl.conf;
    include conf.d/templates/performance.conf;
    include conf.d/templates/security.conf;
}

创建管理员

打开sourcegraph.example.com，创建一个管理员账号。如果你之后想合并这个账号和Azure AD账号，可以使用你的sAMAccountName作为用户名，并且添加一个userPrincipleName作为邮箱地址。

设置Azure AD登录

那这里我们还是用OpenID Connect登录流程。首先去Azure AD创建新应用程序，callback URL填写：

• https://sourcegraph.example.com/.auth/callback

拿到：

• tenant ID
• client ID
• client secret

然后打开Sourcegraph的管理控制台（用户名随便填，密码在第一次启动的时候log会打出来），填入：

{
  "externalURL": "https://sourcegraph.example.com",
  "auth.providers": [
    {
      "type": "builtin",
      "allowSignup": false
    },
    {
      "type": "openidconnect",
      "displayName": "Azure AD",
      "issuer": "https://login.microsoftonline.com/{tenant_id}/v2.0",
      "clientID": "{client_id}",
      "clientSecret": "{client_secret}"
    }
  ],
}

这里需要注意的是externalURL要准确填写。完成以后重启一下Sourcegraph以使externalURL生效。

添加Azure DevOps的Git repo

在External Services里面添加一个Single Git repositories，填入：

{
  "url": "https://{org_name}:{your_access_token}@dev.azure.com/{org_name}/",
  "repos": [
    "{project_name}/_git/{repo_name}"
  ]
}

注意Sourcegraph目前不支持project name中出现空格，详见sourcegraph/issues/2867。
