(20200622已解决)容器docker||Visual Studio Code is unable to watch for file changes in this large workspa

问题描述

如题所述，VSCode无法实时显示文件变动，因为workspace空间太大，文件太多，而linux本身对此有限制。

From vscode offical documents, you can fixed the problem using:

# 查看file watcher limit cat /proc/sys/fs/inotify/max_user_watches # increase the limit $ vim /etc/sysctl.conf fs.inotify.max_user_watches=524288 # 新增这么一行 $ sudo sysctl -p

如果是在docker container内部，上述方案最后会出现：

sysctl: setting key "fs.inotify.max_user_watches": Read-only file system

From Increase fs.inotify.max_user_watches in docker container #628, Docker mount /proc as read-only since many of its knobs are global. If you run that same command on the host, the container will transparently inherit the new setting.

解决方案

直接在容器所在宿主机上运行上述方案，当宿主机更改，容器也会自动更新。
