Debian Wheezy (7.x) on AWS EC2

• 7.7 (18 October 2014)

• 7.6.aws.2 (27 September 2014)

You may wish to use the CloudFormation template and launch your instance with some smart UserData scripts. For some releases you are free to choose the AWS Marketplace AMI, or the AMI that exists in the Debian AMI Account (account number 379101102735). All AMIs shared from the Debian AWS Account and their corresponding EBS snapshots are marked as public so can be inspected by any other AWS user.

Please note that a Marketplace image volume cannot be attached to another running instance (For example, to repair a broken /etc/fstab, or /etc/network/interfaces). This is a limitation of all Marketplace images, as described here: Official AWS documentation

7.7

7.6.aws.2

This release for EC2 was to build a base image with fixes for the Shellshock Bash vulnerability/ies.

7.6

These images are deprecated and will be removed 31st October 2014. Please use the latest point release.

The 7.6 release of Debian was built with bootstrap-vz (formerly called build-debian-cloud), and contains the CloudInit package installed from Debian backports.

7.5

These images are deprecated and will be removed 31st October 2014. Please use the latest point release.

The 7.5 release of Debian was built with bootstrap-vz (formerly called build-debian-cloud), and contains the CloudInit package installed from Debian backports.

Upgrading from previous 6.x.y releases

As is standard with Debian, a simple apt-get update && apt-get dist-upgrade should bring all packages up to date. There is no need to reinstall, but any ?CloudFormation templates and ?AutoScale Launch Configurations should be tested with and then updated to use the current AMI. It is recommended not to use older point releases.

CloudFormation Template

CloudFormation is a templating system for defining AWS resources - see http://aws.amazon.com/cloudformation/

Suggested UserData scripts

As of the 7.3 release, the official Debian !AMIs now support cloud-init. This means you have much more flexability (and power) in what you cna put in your UserData to get your instance to configure. For example, a simple shell script that starts with #!/bin/sh will be executed as previously - so you can chose to enable auto update with the following UserData scripts:

   1 #!/bin/sh
   2 apt-get update && apt-get upgrade -y && apt-get install -y unattended-upgrades python-pip

The unattended-upgrades package is described on UnattendedUpgrades.

Some feature bugs may persist in Cloud-init in Debian 7.3 AMIs; no functionality has been lost, but it appears not all cloud-init directives can be used. Eg: packages, ssh-import-id, apt_update, apt-upgrade.
