Dokku：没有看到集装箱港口

Question

如果有人对此有所了解，请在这里寻求一点 Dokku 帮助。我已经构建了一个新的 Dokku 服务器，并正在尝试部署一个预先存在的应用程序。我知道这个应用程序很好，因为它可以在另一个 dokku 主机上运行，​​没有问题。

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，这很好。我不指望这会奏效。但关键是，当我部署到另一个（工作）dokku 主机时，它返回两个 URL。一个用于nginx，一个用于container，当我导航到容器端口时（每次部署都是随机的，可能是因为容器共存时端口冲突），我可以看到应用程序。

这告诉我 nginx 代理关闭了，容器绑定到了 dokku 主机上的外部接口，对吧？

所以，如果我在新服务器上运行dokku proxy:disable app，然后运行docker ps，我看不到端口下绑定的任何内容。

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

因此，如果我从浏览器测试该框的公共 IP，在端口 5000 上我看不到应用程序（fw 一直打开），但如果我检查端口 80，我确实看到了 nginx 保存页面。所以 nginx 在 80 端口上运行，我希望看到应用程序在 5000 端口上运行？

我看到了这个： [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像0.0.0.0/0:5000 这样的东西，不是吗？

我是 Dokku 的新手，但有一些 Docker 经验。

编辑：只是一些额外的信息......

[root@dokku-host fr-intacct-staging]# dokku urls fr-intacct-staging

我已尝试将配置设置与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并直接连接到容器。

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

[root@dokku-host fr-intacct-staging]#

非常感谢您对此的想法...谢谢。

在 Dokku 对 Slack 的支持下，这很容易解决。我引用的是旧文档。

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..确保选择右下角的版本。版本之间的差异很大。
