你好，
首先，感谢你们提供了市面上最好的论坛软件。
我遇到了一个问题：在重启运行 Discourse 的 Docker 容器时，Discourse 总是尝试重新安装自己。
我选择了多容器配置（默认情况下更优）。
每次重启 Discourse 容器时，该进程总是尝试重新安装。
我原本以为它会检测到数据库已存在并直接可用，但它总是尝试重新安装，并抱怨 ID 冲突。
是否有某个设置可以使其不再重新安装自己？
提前感谢。
你能解释一下你是如何尝试重启容器的吗？
嘿，斯蒂芬，
就像你重启其他容器一样，运行 docker restart discourse
你是如何创建这两个容器的？
你看到了什么看起来像是在尝试安装的消息？
嘿，
伙计们，这是 Docker，所以启动方式没有太多其他选择。
它有一组环境变量。

执行'postInstallation'时出错：ERROR: 重复键值违反了唯一约束 "index_site_settings_on_name"
DETAIL: 键 (name)=(site_contact_username) 已存在。
所以数据库确实存在，但不知为何 Discourse 又尝试重新安装自己……问题是，如何防止这种情况发生？
是否有环境变量可以控制？（我原本期望系统能检测到数据库和配置已存在？）
您正在使用 Bitnami 吗？
您是如何创建容器的？
没错，因为“官方方案”其实不算真正的 Docker 方案，而且过于依赖自定义脚本。我想这样的话也就得不到支持了，哈哈。
Bitnami 镜像不受支持。如果您想使用它，需要与他们联系。
此外，该镜像也非常过时。
说得通……多容器方案有 docker-compose 文件吗？
抱歉，Stephen，我很想使用官方镜像；
discourse/base - Docker Image 那我就改用这个了？
@Stephen is there a list of the environment variables somewhere?
I guess they are just the config file prefixed with DISCOURSE_
?

但说实话，我想我可能只是挂载带有其设置的配置文件。
我知道大家很喜欢这个启动器，但 Docker Compose 呢？我知道这个问题已经被提出过上百次了，而且从我的观察来看，它确实对大家运行得很好 
但还有整整一个 Docker 开发者群体，他们非常了解其工作原理……如果能提供一个 Docker Compose 示例那就太棒了！
我认为您应该更倾向于支持 discoursey，而减少对 dockery 的支持。关于这一点已有许多说明，帮助大家理解为何要这样处理。
嗯，不行，因为 Docker 是运行应用程序的标准方式；将其封装在一个定制的脚本中……无异于重复造轮子。
docker-compose 是一份运行手册，可以交给任何中级服务提供商，他们都知道如何处理。它还能完美集成到 SaltStack 等工具中，而脚本则不行。
当然，我理解原因。这个脚本是多年前 Docker 刚推出时创建的……正如我之前所说，很明显它对支持人员非常有帮助。
另外，当你迁移到 Kubernetes 时……那将会很有趣。
而且，现在四处看看，已经有大量的人在为 Discourse 和 docker-compose 创建 Helm Chart……如果能提供一些支持就太好了。
不过没关系……我现在正在使用 launcher，并从中提取我需要的部分
谢谢，我会仔细阅读。
但重要的是要知道，Docker 已不再陌生；如果不能提供恰当的支持，将阻碍大型组织考虑采用它。
一切顺利……请继续保持这种热情，感谢你们的投入。
这并不属实，Discourse 已被互联网上一些最大的社区所采用。
大型组织要么雇佣了不愿依赖“喂到嘴边”式解决方案的技术人员，要么乐于将相关工作外包给像 CDCK 这样的公司。
对于中型甚至大型社区而言，标准安装方式没有任何问题。如果你想知道 launcher 如何与 Docker 交互，源代码就在其中，可供深入查阅。
