dockerfile - 使用 Dockerfile 安装 Airflow Openshift

Question

我尝试在公共(public) dockerhub 上通过我自己的镜像安装 Airflow，但它在本地运行完美，但当我尝试在 Openshift 上使用它时。我在下面收到此错误。

`ERROR: Could not install packages due to an OSError: [Errno 13]Permission denied: '/.local' Check the permissions.

我的 Dockerfile 适用于 Windows 和 Ubuntu。

在这种情况下，您在使用 Openshift 时必须注意一件事。默认情况下，Openshift 运行具有任意用户 ID 的容器。由于权限问题，依赖固定用户 ID 的容器镜像可能无法启动。因此，请确保您的容器镜像是根据

中描述的规则构建的
