Packer project

I would like to setup a redis database as fast as possible using technology packer. Here is a sample script to give an idea { "builders": [{ "type": "amazon-ebs", "region": "eu-west-1", "source_ami": "ami-480bea3f", "instance_type": "[login to view URL]", "ssh_username": "ubuntu", "ami_name": "packer-example {{timestamp}}" }], "provisioners": [{ "type": "shell", "inline": [ "sleep 30 # important because Amazon is building"] }, { "type": "shell", "inline": [ "sudo apt-get update", "sudo apt-get install -y redis-server" ] }], "post-processors": [{ "comment": "see [login to view URL]", "type": "vagrant", "keep_input_artifact": true }] }
