我的小型论坛（500MB 备份）在 50GB 的磁盘上运行 ./launcher rebuild 时因空间不足而失败。在尝试找出还需要清理什么（apt autoremove 和 ./launcher cleanup 都没有发现任何东西）时，我在 /var/lib/docker/overlay2/.../merged/var/www/discourse/public/assets/locales 中发现了数百兆字节的无用语言环境。
不幸的是，我在截图之前就开始删除它们了，但仍然可以看到许多针对同一种语言的重复的、似乎是转译过的 JavaScript 文件。可以在 Discourse 代码中做些什么来避免这种情况吗？.map 文件有什么用途吗？
此外，我的论坛只使用英语。如何选择退出所有其他语言？
/usr/lib/locale 中还有几百兆字节的语言环境，我希望不必手动释放它们：
前提是此服务器仅运行 Discourse，您可以尝试运行以下命令：
cd /var/discourse
./launcher stop app
docker rmi -f $(docker images -aq)
./launcher rebuild app
这将停止 Discourse，删除所有 Docker 镜像，然后重建 Discourse，下载我们当前的镜像。
至于累积的文件，@david 我们是否有类似于 rake s3:expire_missing_assets 的本地存储功能？
容器内的 /var/www/discourse/public 目录未挂载到主机……所以我很确定在标准安装中，每当你执行 ./launcher rebuild app 时，它们都会被丢弃。
但是，关于网络更新呢？
服务器确实只运行 Discourse。
我运行了命令，遇到了一些关于区域设置的错误，现在输出卡在了 FATAL: database files are incompatible with server. The data directory was initialized by PostgreSQL version 13, which is not compatible with this version 15.12。
我是否不小心删除了某个重要的区域设置文件？en_US.UTF-8 似乎已成功重新生成。

^C^C^C
该进程不响应 Ctrl+C。
是的，在这种情况下它们会持续存在。但我们至少每 6 个月强制进行一次 CLI 更新，所以我不认为这会是个大问题。
关于本地化，我们正计划进行一些更改，以便在首次请求时“即时”编译它们。这应该会更有效率，因为大多数网站只使用一种语言。
这看起来不妙。服务器内存是否非常低？是否配置了交换空间？
关于数据库更新，请参阅 PostgreSQL 15 更新
服务器有 2GB RAM。Swap 设置为另外 2GB。
我将其从 Ubuntu 16（我知道）原地升级到 18，更新了 /var/discourse/containers/app.yml 以包含 三个 locale env: 设置，现在 Postgress 从 v13 迁移成功，并且最新版本的 Discourse 似乎在 Ubuntu 18 上运行良好。
