Dokku - 设置后添加域 [英] Dokku - Add domain after setup

问题描述

我在我的 Digital Ocean Droplet 上安装了 Dokku，但在设置我的 dns 记录之前安装了 Dokku，所以 Dokku 安装在 IP 上.现在我更改了我的 dns 记录，因此可以通过 site.com 访问该站点.我可以通过 site.com:port 访问我之前创建的 Dokku 容器，如何更改 Dokku 设置以访问我的应用程序 - appname.site.com

I installed Dokku on my Digital Ocean droplet, but did it before setting my dns records, so Dokku was installed on IP. Now I changed my dns record, so site can be accessed through site.com. I can access my previously created Dokku containers through site.com:port, how can I change Dokku settings to access my app like this - appname.site.com

推荐答案

Per https://github.com/progrium/dokku:

设置一个域和一个指向该主机的通配符域.确保/home/dokku/VHOST 设置为此域.默认情况下它设置为主机拥有的任何主机名.该文件仅在以下情况下创建主机名可以通过 dig (dig +short $(hostname -f)) 解析.否则您必须手动创建文件并将其设置为您的首选领域.如果推送应用程序时此文件仍然不存在，dokku 将发布带有端口号的应用程序(即http://example.com:49154 - 请注意缺少的子域).

Set up a domain and a wildcard domain pointing to that host. Make sure /home/dokku/VHOST is set to this domain. By default it's set to whatever hostname the host has. This file is only created if the hostname can be resolved by dig (dig +short $(hostname -f)). Otherwise you have to create the file manually and set it to your preferred domain. If this file still is not present when you push your app, dokku will publish the app with a port number (i.e. http://example.com:49154 - note the missing subdomain).

要解决此问题，您首先需要更新/home/dokku/VHOST 文件，添加域名——这将修复任何新生成的部署，但需要从/home/中删除现有应用程序dokku 目录按名称(/home/dokku/foo、/home/dokku/bar 等)并重新部署以使此更改生效，因为每个 Dokku 应用程序在这些/home/dokku/路径中都有一个单独的 nginx.conf 和那些需要重写.

To fix the issue, you will first need to update the /home/dokku/VHOST file, adding the domain name -- this will fix any newly generated deployments, but existing apps will need to be deleted from the /home/dokku directory by name (/home/dokku/foo, /home/dokku/bar, etc.) and redeployed for this change to take effect, since each Dokku application has a separate nginx.conf within those /home/dokku/ paths and those will need to be re-written.
