Files not updating in the container

inotify watcher limit

If your files are not updating you should check the maximum permitted inotify watchers. On most systems it will be a command like this:

  • cat /proc/sys/fs/inotify/max_user_watches

The default value is often 8192, which can be too low for modern applications with a Git repository and lots of dependencies being pulled in by a package manager. You can change this to a more suitable number, usually 65536 is sufficient. The location of the inotify config is different on different systems, here is an Ubuntu guide

Editor does not update file inumber

The way some editors behave on save means the inumber of the file does not change, so unison does not pick up a difference and the files in your containers do not update. Notable culprits are vim and Atom. In both cases there are fixes - for example the local-history plugin for Atom forces it to behave as we need. If you have mysterious issues with files not changing in your containers and it isn't the inotify watcher limit above, check how your editor behaves.
