As far as I can see, you can’t add a slug, though you don’t need to provide doctl with a slug to create a new Droplet using a previously generated snapshot, you just need to pass the ID of the snapshot in place of the slug.

So, for example, I pulled a list of images using:

doctl compute image list

The last image in the list was a snapshot I created before running that command. I then took the ID of that image and passed it to the create command and it created a new droplet using the snapshot.

doctl compute droplet create name --size 8gb --image ID_OF_IMAGE --region nyc1 --ssh-keys FP_SSHKEY

Just sub out ID_OF_IMAGE with the image ID of your snapshot and FP_SSHKEY with the fingerprint for your SSH Key.
