Hi I am migrating from Docker Desktop to Rancher Desktop on Mac and am running into issues with bind mounting certain directories (e.g. /tmp or /srv). It appears to succeed for /Users for example. In Docker Desktop there was a file share settings that needed to be modified to allow for exporting other paths besides the defaults for macOS. Is there a similar configuration available for Rancher Desktop? If not, is there documentation anywhere on what directories can be bind mounted?

Thanks, I'm assuming there's no way to expand that list of default directories via configuration?

I wouldn't make assumptions 🙂

Adding the symlinks won't work because they don't resolve inside the VM; you have to bind-mount the target of the symlink as well. You can do this from an

override.yaml

file:

$ cat ~/Library/Application\ Support/rancher-desktop/lima/_config/override.yaml
mounts:
- location: /Volumes/ThunderBlade
  writable: true

What I imagine is on the host mapping

/tmp/foo

to ~/foo and in the container map

/tmp/foo

to the same.

Note that a "Factory Reset" will also delete your "override.yaml" file

Factory Reset should really dump the "trashed" settings into a folder, e.g. on the desktop "discarded rancher desktop settings (n)"

Oh, ok, I thought you were creating

~/opt -> /opt

, and that will not work 🙂

I should have been more precise 🙂

Yes, your text was correct; I was just making the wrong assumptions because I have various symlinks from my home directory to an external RAID device, which is why I need the extra mount (out of space on the internal drive):

$ ls -l ~/suse
lrwxr-xr-x  1 jan  staff  26  7 Feb  2020 /Users/jan/suse -> /Volumes/ThunderBlade/suse

Been there had that problem 🙂

Should have ordered that 4TB internal SSD...

I asked for it, the finance guy vetoed

@fast-garage-66093 thanks -- that worked!
