Unable to push code to fresh Dokku container: unable to apply apparmor profile: apparmor failed to apply profile

Question

在我的服务器上，我安装了 dokku 并创建了一个新应用程序：myNodeApp

$ dokku apps:create myNodeApp

在我的本地仓库中，我添加了 dokku 遥控器，现在想在 git add 之后将现有代码推送到我的容器中。 :

$ git push dokku main

这是 Docker 问题。 Docker v23 不小心添加了对 AppArmor 的硬依赖，v23.0.1 实施了错误修复，将错误消息更改为您遇到的错误消息。

目前，修复是以下之一：

a) 将 Docker 降级到 v23 以下

b) 安装 AppArmor（我也不得不重启）

c) 等待新错误的问题得到修复
