If you must turn off the control for use unsupported storage than checking of the latest launcher creates infinite loop.

So you’re saying that if you shoot yourself in the foot you can’t walk properly anymore? Why are you using an unsupported storage?

Have you considered… using a supported Docker storage method? :thinking:

Our white list looks good to me, maybe even a bit too wide. I am not sure if we should keep carrying overlay1 as a supported driver. Also btrfs can be somewhat dodgy. @saj do you think we should drop overlay from our supported list? (keeping overlay2)

Yes, I think it would be reasonable to drop the overlay storage driver from the whitelist. :+1: Foremost in my mind was not unduly inconveniencing users on enterprise distros. Docker Inc. appear to have dropped their support for all platforms but the following: Debian 9 (and later) EL7 Ubuntu 16.04 (and later) The kernels in these distributions should support overlay2. I can’t think of a reason why someone would choose to use the older overlay driver when their system meets overlay2 requirements.

I guess we could add an ALLOW_ME_TO_USE_AN_UNSUPPORTED_STORAGE_DRIVER environment variable override?

Ayup. I searched the launcher script for prior art - ag -o '[A-Z]{4,}' launcher | sort | uniq There’s no existing pattern for this manner of knob. I propose the DANGER_ prefix. I think it communicates the need for the user to take on additional responsibility. diff --git a/launcher b/launcher index b629bfc..3aed081 100755 --- a/launcher +++ b/launcher @@ -154,14 +154,19 @@ check_prereqs() { # 2. running an approved storage driver? if ! $docker_path info 2> /dev/null | egrep -q '^Storage Driver: (aufs|btrfs|zfs|overlay|overlay2)$'; then - echo "Your Docker installation is not using a supported storage driver.

OK so let’s remove btrfs and overlay from the whitelist?

edit: that’s done now
