Install Discourse for development using Docker

[david (David Taylor)]

感谢 Aubrey、topological 和 FlyingCat 的报告。我们已在 Discourse core 中撤销了该提交。

cvx 确定了问题的根源，并在上游 mail gem 上提出了一个问题：

Incorrect file permissions in 2.8.0

一旦解决，我们将再次切换回官方 gem。

我在 d/boot_dev --init 时遇到另一个错误。这是在一个全新安装的 Ubuntu 22.04 上，并遵循 OP 中的指南。

编辑：已解决——它非常不喜欢以 root 身份运行。请确保您从一开始就以普通用户身份运行。

如何禁用开发模式下的 CORS？
我想从 http://localhost:3001 源发送 CORS 请求，但 cors_origin 设置无效。Access-Control-Allow-Origin 标头未出现。
算了，我解决了。似乎 enable_cors 设置在开发模式下被忽略了。

config/initializers/008-rack-cors.rb

因此，CORS 中间件从未安装。我只是在我本地的 discourse 仓库中删除了 if 语句，这样中间件在任何情况下都会被安装。

[nordize]

也许一位开发者（或者本指南的作者 @rishabh？）能帮我解决这个问题。我严格按照 OP 指南操作，在一个新的虚拟机上安装了 Ubuntu 22.04，并使用了一个普通用户（非 root）账户。

• 将插件符号链接到 discourse/plugins/ 子文件夹，除非我执行 d/shutdown_dev; d/boot_dev，否则看不到插件初始化 JS 代码的更改，尽管我重启了 d/rails s 和 d/ember-cli。

• 将插件复制到 discourse/plugins/ 子文件夹，可以看到插件初始化 JS 代码的更改，而无需执行 d/shutdown_dev; d/boot_dev，只需重启 d/rails s 和 d/ember-cli。

所讨论的插件是 discourse-math，我正在更改的代码位于 assets/initializers/javascript/*.js。我注意到这些文件是侧载的，并且浏览器不会直接通过 HTTP GET 调用它们（不确定这是否有区别）。

附注：我刚开始接触 Discourse，但对 Web/JS 开发并不陌生（换句话说，不用问我是否刷新了浏览器 ）。

[DonH]

能否请开发者检查此错误？它似乎与 Ruby 相关，而不是我个人的情况。我正在按照 Docker 安装的说明在 Windows 上安装 Discourse for Development，并且以前已成功执行过几次。脚本进行到数据库安装时失败了。第一个警告看起来并不致命，但在转储文件下方有一个丢失的 xss.min.js 文件，这是致命的：

‘’'您正在尝试在测试环境中运行迁移，并且没有加载插件，请设置 LOAD_PLUGINS 为 1
DEPRECATION WARNING：使用旧版连接处理已弃用。请在您的应用程序中将 legacy_connection_handling 设置为 false。

新的连接处理不支持 connection_handlers getter 和 setter。

[tarek (Tarek Loubani)]

非常感谢您提供的这个很棒的资源。有几点可以帮助您：

1. 这是完全删除和重启数据的命令：
   docker stop discourse_dev ; docker rm discourse_dev ; sudo rm -rf data ; rm -rf tmp/*

2. 如果您遇到上述之类的迁移问题，请确保您具有正确的权限。您必须属于 docker 组或 sudo（不推荐的第二种选择）。

3. 在启动 d/ember-cli 之前，请让 d/rails s 完成，否则会出现一些奇怪的问题。

[DonH]

谢谢你，Tarek。

在擦除安装并重复克隆过程后，初始化过程中出现了完全相同的错误，即：
“rake aborted!
”Errno::ENOENT: No such file or directory @ rb_sysopen”

但这次我能够成功继续，并看到了“Congratulations.”。谢谢。

现在，由于脚本提前终止，没有开发管理员电子邮件，也没有配置文件。如果有人能找出初始化问题就好了。

我使用命令“d/rake admin:create”配置了一个管理员电子邮件，并输入了一个有效的电子邮件和（至少 10 个字符）密码。

然后，我按照指示在浏览器中成功启动了 Discourse。

[AquaL1te]

有人在使用 Fedora 吗？这增加了一些复杂性，因为 Podman 和 SELinux 用于增强安全性。Podman 应该不是什么大问题，它是 OCI 兼容的，并且安装了 podman-docker，所有 Docker 命令都会被翻译成 Podman 命令。对于 SELinux，我认为我也找到了正确的解决方法，但仍然遇到了一个问题。

因此，在 discourse 目录下，我运行此命令 mkdir -vp data/postgres; sudo semanage fcontext -a -t svirt_sandbox_file_t \"/home/user/discourse/data(/.*)?\" \u0026\u0026 restorecon -rv . 来应用一个我认为足够（至少 SELinux 错误消失了）的 SELinux 上下文标签。

但是之后我仍然遇到这个错误：

discourse 目录下的 log 目录是空的，我该如何更好地进行故障排除？
路径似乎已正确设置以查找 Gem 文件。

@AquaL1te

有人在这里使用 Fedora 吗？这增加了一些复杂性，因为 Podman 和 SELinux 用于增强安全性。Podman 实际上不是问题，我希望如此，它是 OCI 兼容的，并且安装了 podman-docker，所有 Docker 命令都将转换为 Podman 命令。对于 SELinux，我认为我也找到了正确的修复方法，但我仍然遇到一个问题。

很久以前，我曾成功地从头开始构建了一个虚拟 Fedora 开发环境，但无法让生产环境正常工作。我还询问了 Podman Q，有人好心回复说这是可能的，但有很多东西需要更改，而他没有时间去做。

我很想让开发版和生产版的 Fedora 版本都能运行。 .

我想使用 Ubuntu，但不知何故它与 spice-vdagent 工作不佳，运行虚拟机时出现许多图形错误。Fedora 工作起来像黄油一样流畅……我以为容器解决了可移植性问题 我猜我只能设置一个无头 Ubuntu 系统并通过 SSH 登录。

---

我在 Ubuntu Server 22.04 中遇到同样的错误。

[AquaL1te]

我也有这个问题。遵循了@tarek的建议并仔细检查了。问题仍然存在。我还清理了整个discourse目录并从头开始。在虚拟机中使用Ubuntu 22.04.01，并使用Ubuntu可用的最新Docker。

[tarek (Tarek Loubani)]

截至当前的 git master，这不会成功完成。我认为这是核心中的一个错误。要设置并运行开发环境，请在出现错误后执行以下操作：

d/rake db:migrate
d/rake admin:create
d/rails s

另外在接下来的两个终端中，输入 d/ember-cli 和 d/mailhog。

[tarek (Tarek Loubani)]

有什么办法可以阻止 d/rails s 显示所有查询输出吗？这让我很难使用 byebug 等工具来找出我遇到的错误。

[merefield (Robert)]

尝试： DISCOURSE_DEV_LOG_LEVEL=info bin/rails s

你好，

(See full trace by running task with --trace)

我尝试运行：

d/rake db:migrate RAILS_ENV=development

但仍然出现相同的错误。有人遇到过这种情况吗？

[merefield (Robert)]

我怀疑你正在使用和以前一样的数据库，所以它已经迁移过了？

[merefield (Robert)]

实际上 @hyphalos 我收回之前的话，我可以在容器内使用以下 shell 命令重现此问题：

discourse@discourse:/src$ sudo su postgres -c 'psql discourse -c \"drop database discourse_test\"'
DROP DATABASE
discourse@discourse:/src$ sudo su postgres -c 'psql discourse -c \"create database discourse_test\"'
CREATE DATABASE
discourse@discourse:/src$ sudo su postgres -c 'psql -c \"grant all privileges on database discourse_test to discourse;\"'
GRANT
discourse@discourse:/src$ RAILS_ENV=test rake db:migrate

这里是不是有什么不对劲？

看起来这个迁移可能会有问题？：

这很奇怪（？），因为：

这似乎不会影响 tests-passed，只影响 stable 分支？

感谢 @RGJ，这可能有助于阐明问题：

嘿 @Robert，

我以为我疯了，以为只有我遇到了这个问题。我一直在努力寻找解决方法。我之前有一篇帖子，在那里我找到了书签问题的解决方法，但又遇到了另一个问题：
