I just want to provision a standard Ubuntu 12.04 image with a shell script, and then package it so I can use it with Vagrant. This is the configuration I wrote:
{
"builders": [{
"type": "vagrant",
"iso_url": "http://releases.ubuntu.com/12.04/ubuntu-12.04.3-server-amd64.iso",
"iso_checksum": "2cbe868812a871242cdcdd8f2fd6feb9",
"iso_checksum_type": "md5"
}],
"provisioners": [{
"type": "shell",
"script": "bootstrap.sh"
}],
"post-processors": ["vagrant"]
}
Unfortunately 'packer validate packer.json' throws me the following error: 'No builder returned for name: vagrant
How do I solve this?
