Question

如果有人对此有所了解，请在此处呼唤一点Dokku帮助。我建立了一个新的Dokku服务器，并试图部署一个预先存在的应用程序。我知道该应用程序很好，因为它可以在其他dokku主机上正常运行。

当我在此服务器上部署应用程序时，它返回一个地址...这是无效的。这是盒子的主机名，可以。我不希望它能起作用。但是关键是，当我部署到另一个（运行中的）dokku主机时，它将返回两个URL。一种用于nginx，另一种用于container，当我导航到容器端口时（每个部署都是随机的，可能是由于容器共存时端口冲突），我看到了该应用程序。

这告诉我nginx代理已关闭，并且容器已绑定到dokku主机上的外部接口，对吗？

因此，如果在新服务器上运行dokku proxy:disable app，然后再运行docker ps，则看不到端口下面的任何内容。

       http://dokku-host.c.fr-intacct-staging.internal:5000 (container)

因此，如果我从浏览器测试该机顶盒的公用IP，则在端口5000上看不到该应用程序（一直打开），但是如果我检查端口80，则确实看到了nginx保留页面。那么nginx在端口80上运行，我希望看到该应用在端口5000上运行吗？

我看到了： [root @ dokku-host〜]＃docker ps

CONTAINER ID        IMAGE                             COMMAND             CREATED             STATUS              PORTS               NAMES

似乎没有任何东西绑定到外部接口。我当然希望在那里看到类似0.0.0.0/0:5000的东西，不是吗？

我是Dokku的新手，但是有一些Docker经验。

编辑：只是一些额外的信息...

来自旧主机：

来自新主机：

[root@dokku-host fr-intacct-staging]# dokku urls fr-intacct-staging
http://dokku-host.c.fr-intacct-staging.internal:5000 (container)

我尝试使配置设置与dokku config set fr-intacct-staging xxxx=xxx相同，但无济于事。

我的直觉是我需要阻止它尝试使用nginx作为代理，将容器绑定到外部接口，然后直接连接到容器。

但是：

[root@dokku-host fr-intacct-staging]# dokku proxy:disable fr-intacct-staging
-----> proxy is already disable for app (fr-intacct-staging)
[root@dokku-host fr-intacct-staging]# docker ps
CONTAINER ID        IMAGE                             COMMAND             CREATED             STATUS              PORTS               NAMES
d9f6006f0eaf        dokku/fr-intacct-staging:latest   "/start web"        35 minutes ago      Up 35 minutes                           fr-intacct-staging.web.1
[root@dokku-host fr-intacct-staging]#

真的很感谢对此的想法...谢谢。

Answer 1

在Slack中，在Dokku支持的帮助下，这很容易解决。我引用的是旧版文档。

对此的解决方法是：

dokku proxy:disable fr-intacct-staging
dokku network:set fr-intacct-staging bind-all-interfaces true
dokku ps:rebuild fr-intacct-staging

这里的文档很棒：http://dokku.viewdocs.io 但是..请确保选择右下角的版本。版本之间的差异很大。

Dokku：没有看到容器端口
