Variables should always be strings. Array type options which gets a
variable splits them on comma. You variables.json should be:
{
"ami_users" : "1111111111111,222222222222,333333333333",
"ami_regions": "us-east-1,eu-west-1"
}
And in your packer template you use them like this:
{
"variables": {
"ami_users": null,
"ami_regions": null
},
"builders": [
{
"type": "amazon-ebs",
"ami_users": "{{ user `ami_users` }}"
}
]
