# Creating AMI Artifacts with Atlas
|
||
|
|
|
||
|
|
In an [immutable infrastructure](/help/intro/use-cases/continuous-deployment-of-immutable-infrastructure)
|
||
|
|
workflow, it's important to version and store full images (artifacts)
|
||
|
|
to be deployed. This section covers storing [AWS AMI](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AMIs.html)
|
||
|
|
images in Atlas to be queried and used later.
|
||
|
|
|
||
|
|
Note the actual AMI does _not get stored in Atlas_. Atlas
|
||
|
|
simply keeps the AMI ID as a reference to the target image. Tools
|
||
|
|
like Terraform can then use this in a deploy.
|
||
|
|
|
||
|
|
### Steps
|
||
|
|
|
||
|
|
If you run Packer in Atlas, the following will happen after a [push](/help/packer/builds/starting):
|
||
|
|
|
||
|
|
1. Atlas will run `packer build` against your template in our infrastructure.
|
||
|
|
This spins up an AWS instance in your account and provisions it with
|
||
|
|
any specified provisioners
|
||
|
|
1. Packer stops the instance and stores the result as an AMI in AWS
|
||
|
|
under your account. This then returns an ID (the artifact) that it passes to the Atlas post-processor
|
||
|
|
1. The Atlas post-processor creates and uploads the new artifact version with the
|
||
|
|
ID in Atlas of the type `amazon.image` for use later
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
Below is a complete example Packer template that starts an AWS instance.
|
||
|
|
|
||
|
|
{
|
||
|
|
"push": {
|
||
|
|
"name": "%{DEFAULT_USERNAME}/frontend"
|
||
|
|
},
|
||
|
|
"provisioners": [],
|
||
|
|
"builders": [
|
||
|
|
{
|
||
|
|
"type": "amazon-ebs",
|
||
|
|
"access_key": "",
|
||
|
|
"secret_key": "",
|
||
|
|
"region": "us-east-1",
|
||
|
|
"source_ami": "ami-2ccc7a44",
|

"instance_type": "c3.large",

"ssh_username": "ubuntu",
|
||
|
|
"ami_name": "Atlas Example {{ timestamp }}"
|
||
|
|
}
|
||
|
|
],
|
||
|
|
"post-processors": [
|
||
|
|
{
|
||
|
|
"type": "atlas",
|
||
|
|
"artifact": "%{DEFAULT_USERNAME}/web-server",
|
||
|
|
"artifact_type": "amazon.image"
|
||
|
|
}
