Previously the location the file was uploaded to was set internally and used ${env:SYSTEMROOT}/Temp as the destination folder. By default, in order to inject the required environment variables, the file is 'dot sourced' by the 'execute_command' using the {{ .Vars }} variable. Unfortunately the inclusion of the dollar in the path caused issues for users connecting over ssh as the (typically bash) shell running the execute command would try and interpret the dollar sign. The change allows users to specify the location the file is uploaded to, thereby allowing the user to specify a custom 'execute_command' that escapes any dollar signs that could be present in the path. If not set the upload path now defaults to using C:/Windows/Temp as the upload folder. |

Packer is a tool for building identical machine images for multiple platforms from a single source configuration.
Packer is lightweight, runs on every major operating system, and is highly performant, creating machine images for multiple platforms in parallel. Packer comes out of the box with support for many platforms, the full list of which can be found at https://www.packer.io/docs/builders/index.html.
Support for other platforms can be added via plugins.
The images that Packer creates can easily be turned into Vagrant boxes.
Quick Start
Download and install packages and dependencies
go get github.com/hashicorp/packer
Note: There is a great introduction and getting started guide for those with a bit more patience. Otherwise, the quick start below will get you up and running quickly, at the sacrifice of not explaining some key points.
First, download a pre-built Packer binary for your operating system or compile Packer yourself.
After Packer is installed, create your first template, which tells Packer
what platforms to build images for and how you want to build them. In our
case, we'll create a simple AMI that has Redis pre-installed. Save this
file as quick-start.json
. Export your AWS credentials as the
AWS_ACCESS_KEY_ID
and AWS_SECRET_ACCESS_KEY
environment variables.
{
"variables": {
"access_key": "{{env `AWS_ACCESS_KEY_ID`}}",
"secret_key": "{{env `AWS_SECRET_ACCESS_KEY`}}"
},
"builders": [{
"type": "amazon-ebs",
"access_key": "{{user `access_key`}}",
"secret_key": "{{user `secret_key`}}",
"region": "us-east-1",
"source_ami": "ami-af22d9b9",
"instance_type": "t2.micro",
"ssh_username": "ubuntu",
"ami_name": "packer-example {{timestamp}}"
}]
}
Next, tell Packer to build the image:
$ packer build quick-start.json
...
Packer will build an AMI according to the "quick-start" template. The AMI will be available in your AWS account. To delete the AMI, you must manually delete it using the AWS console. Packer builds your images, it does not manage their lifecycle. Where they go, how they're run, etc. is up to you.
Documentation
