getting mounts failed on docker-compose up

[Kolin Ohi]

Hi - on latest mac docker and latest commits on localstack, I'm getting mount errors running docker-compose up

(it worked yesterday before an update to docker and repulling)

(seems like a similar issue to the one fixed with commit 8124df3641ebc5854dae8c05911a6b3edc171c6e ?)

$ docker-compose up
Creating network "localstack_default" with the default driver
Creating localstack_localstack_1 ...
Creating localstack_localstack_1 ... error

ERROR: for localstack_localstack_1  Cannot start service localstack: Mounts denied:

You can configure shared paths from Docker -> Preferences... -> File Sharing.

Thanks for reporting. As a workaround, you can use the following command:

TMPDIR=/private$TMPDIR docker-compose up

The problem with recent versions of MacOS is that /var is a symlink to /private/var, and the Docker settings dialog does not allow you to add /var as a file sharing path. There is an open ticket here that seems to be related: https://github.com/docker/for-mac/issues/1298

We should probably add that to the Troubleshooting section of the README

This has been fixed in recent versions, also the README has been updated. Thanks
