#nubis-builder secrets All *.json files in this directory will be loaded by nubis-builder automatically. It is intended that you store access credentials and other sensitive data within this directory. All *.json and *.pem files will be ignored by git.

You can technically store any valid packer json here (such as additional builders, provisioners, etc) but that's untested and not recommended. If you have sensitive data within a builder or provisioner you should parameterize it and store those parameters here.

Quick Start

If you are following any of the quick start guides you can use this simplified version of the variables.json file. The portions we leave out are necessary only if you are building ephemeral (non ebs backed) EC2 instances. In this case use the following example file, making sure to insert your AWS API keys where necessary. This example will build in us-west-2 (Oregon). If you wish to build in another region/account (or not using Mozilla credentials) these setting will not work for you and you should read the long descriptions below.

Quick start example variables.json:

{
  "variables": {
    "aws_access_key": "",
    "aws_secret_key": "",
    "aws_account_id": "647505682097",
    "aws_region": "us-west-2",
    "ami_regions": "us-east-1,us-west-2",
    "iam_instance_profile": "",
    "nubis_account_id": ""
  }
}

Variable descriptions

aws_access_key and aws_secret_key

Your AWS API credentials. If you're running nubis-builder on a EC2 instance you should use an IAM roles instead.

aws_region

The region that your packer builder instances will run in. Please use ami_regions to copy AMIs to other regions, you do not need to build in every region.

ami_regions

The regions (commma-separated) to copy the AMIs to

aws_account_id

Your AWS Account ID. This is used for instance-store backed AMI building, required by packer. See the packer documentation for more information.

aws_instance_s3_bucket, aws_x509_cert_path, aws_x509_key_path

Additional packer parameters for the instance-store builder. Your instance-store builds will be stored in the bucket specified by aws_instance_s3_bucket. The certificates specified by aws_x509_cert_path and aws_x509_key_path are passed to ec2-bundle-vol during the build process.

iam_instance_profile

This is the instance profile that your EC2 builders will be launched under. You can use this to facilitate access to private S3 buckets, for example.

nubis_account_id

This is the account ID where public Nubis images (like nubis-base) are published and should be searched for. You can set this to a different account if you wish or the special value 'self' to look in your own account.
