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 creating AMIs (EC2), VMware
|
|
images, and VirtualBox images. Support for more platforms can be added via
|
|
plugins.
|
|
|
|
## Quick Start
|
|
|
|
First, get Packer by either downloading a pre-built Packer binary for
|
|
your operating system or [downloading and compiling Packer yourself](#developing-packer).
|
|
|
|
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`. Be sure to replace any credentials with your
|
|
own.
|
|
|
|
```json
|
|
{
|
|
"builders": [{
|
|
"type": "amazon-ebs",
|
|
"access_key": "YOUR KEY HERE",
|
|
"secret_key": "YOUR SECRET KEY HERE",
|
|
"region": "us-east-1",
|
|
"source_ami": "ami-de0d9eb7",
|
|
"instance_type": "m1.small",
|
|
"ssh_username": "ubuntu",
|
|
"ami_name": "packer-quick-start {{.CreateTime}}"
|
|
}]
|
|
}
|
|
```
|
|
|
|
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](https://console.aws.amazon.com/). Packer
|
|
builds your images, it does not manage their lifecycle. Where they go, how
|
|
they're run, etc. is up to you.
|

## Documentation
|
|
|
|
Full, comprehensive documentation is viewable on the Packer website:
|
|
|
|
http://www.packer.io/docs
|
|
|
|
## Developing Packer
|
|
|
|
If you wish to work on Packer itself, you'll first need [Go](http://golang.org)
|
|
installed (version 1.1+ is _required_). Next, clone this repository then just type `make`.
|
|
In a few moments, you'll have a working `packer` executable:
|
|
|
|
```
|
|
$ make
|
|
...
|
|
$ bin/packer
|
|
...
|
|
```
|
|
|
|
You can run tests by typing `make test`. This will run tests for Packer core
|
|
along with all the core builders and commands and such that come with Packer.
