docker - 创建挂载源路径时Docker撰写错误

Question

我使用cloudestuary创建了docker-compose.yml。下载并将其放在我的Laravel项目文件夹中并运行docker-compose up -d之后，将进行下载，然后得到以下消息:

ERROR: for worker-1 Cannot start service worker-1: error while creating mount source path '/var/www/html/lensin/html': mkdir /var/www: read-only file system

ERROR: for nginx Cannot start service nginx: error while creating mount source path '/var/www/html/lensin/html': mkdir /var/www: read-only file system

ERROR: for app Cannot start service app: error while creating mount source path '/var/www/html/lensin/html': mkdir /var/www: read-only file system

ERROR: for workspace Cannot start service workspace: error while creating mount source path '/var/www/html/lensin/html': mkdir /var/www: read-only file system ERROR: Encountered errors while bringing up the project.

我在Ubuntu 17上运行，甚至尝试将777设置为所有文件夹，并使用sudo运行它，但结果是相同的。我也尝试过移动文件并在yml中编辑卷。

这是我的docker compose文件:

从快照中删除Docker

snap remove docker

删除docker目录和旧版本(如果还不存在，也可以)

rm -R /var/lib/docker

sudo apt-get remove docker docker-engine docker.io

安装官方Docker软件包: https://docs.docker.com/install/linux/docker-ce/ubuntu/
