# Packer Notes

[HashiCorp Packer](https://packer.io/)
Used to create the AWS AMI. Packer is run on your local laptop. 

## Installation

https://www.packer.io/downloads
Use brew on the mac

The `Makefile` is used to document the different images that you are able to build. Make doesn't provide any parts of the build process, just convenience. 

`Packer` is required to partition the hard drives out before ec2 launch. 

## Usage

username: `centos`          
key in Vault called `msoc-build` 

to run through a new build use the `make` command. 

See the `README.md` in the [Packer/README.md](https://github.xdr.accenturefederalcyber.com/mdr-engineering/msoc-infrastructure/blob/develop/packer/README.md)

```
make aws-test
make multi7
AWS_PROFILE=mdr-test packer build -on-error=ask -only=master -var-file=rhel7_hardened_variables_test.json rhel7_hardened_multi_ami.json
```

## Troubleshooting Help
Add --debug to pause execution at each stage            
Add --on-error=ask
