packer2terraform

packer2terraform turns Packer's machine-readable output into Terraform-readable tfvars. For example, you have Packer build an AMI that Terraform deploys to AWS.

Usage

packer2terraform reads from STDIN and writes to STDOUT.

packer2terraform -f [input filename] -template [template filename]

Example

packer -machine-readable build app.json | packer2terraform > app.tfvars

Or:

packer2terraform -f packer_out.csv -template tmpl.tfvars > app.tfvars

Given this CSV input:

1432168589,amazon-ebs,artifact-count,2
1432168589,amazon-ebs,artifact,0,builder-id,mitchellh.amazonebs
1432168589,amazon-ebs,artifact,0,id,us-west-1:ami-df76909b
1432168589,amazon-ebs,artifact,0,string,AMIs were created:\n\nus-west-1: ami-df76909b
1432168589,amazon-ebs,artifact,0,files-count,0
1432168589,amazon-ebs,artifact,0,end
1432168589,amazon-ebs,artifact,1,builder-id,mitchellh.amazonebs
1432168589,amazon-ebs,artifact,1,id,us-west-2:ami-df79909c
1432168589,amazon-ebs,artifact,1,string,AMIs were created:\n\nus-west-2: ami-df79909c
1432168589,amazon-ebs,artifact,1,files-count,0
1432168589,amazon-ebs,artifact,1,end

And this template:

variable "images" {
    default = {
{{range .Artifacts}}
        {{index .IDSplit 0}} = "{{index .IDSplit 1}}"{{end}}
    }
}

packer2terraform will produce this output:

variable "images" {
    default = {

        us-west-1 = "ami-df79909b"
        us-west-2 = "ami-df79909c"
    }
}
