Docker-compose 错误 [内部] 启动 buildkit，http：部署 Django 时主机标头无效

Question

我正在使用 docker compose 在 Ubuntu 22.04.3 上创建 Django 服务器、MySQL 数据库和 Django Q。但是当我运行 docker-compose -f ./docker-compose.yml 时，出现以下错误：

我尝试重新安装我的 docker 并避免使用 BuildKit，但它们不起作用。我想在 docker 上部署 Django REST 服务和 Django Q。

我也有同样的问题。我猜你正在使用 snap docker。我服务器上的（snap）docker版本（2904）也有同样的问题。

在我的笔记本电脑上，docker 版本（2893）按预期工作。我将笔记本电脑上的快照通道更改为最新/候选（2904），并且出现了同样的问题。切换回最新/稳定版，一切都恢复正常。

所以：

snap info docker

获取一些版本信息。

使用：

snap refresh --stable docker

切换到稳定频道。

现在，正如预期的那样，您的项目在我的笔记本电脑上构建。我确实必须改变：

FROM python 3.10

到

FROM python:3.10

该切换适用于我的笔记本电脑 (Ubuntu 23.10)，但不适用于我的服务器 (Ubuntu 18.04.6)。

在服务器上我必须使用：

sudo snap refresh --revision=2893 docker
