Find the latest 64-bit HVM- and EBS-enabled Amazon Machine Images (AMI) available for certain OS distributions. For most distributions, we look for gp2 block devices. Images are returned in reverse chronological order, the most recent being the first listed.
When I launch AWS EC2 instances for myself or for clients, I typically fall back on just a few OS/Distribution options: Amazon Linux, CentOS, Red Hat Enterprise Linux, Ubuntu LTS, or FreeBSD. I like to use the newest AMI available, so I hacked up this script to list the newest images for those distributions.
This is a bash script, so you'll need bash installed.
More importantly, you'll need the AWS Command Line
Interface installed and configured.
aws is a Python program, so you'll need Python installed to run
it. Most mainstream package managers have access to an
package. If not, you can install it via Python's
AWS CLI Configuration
Unless you specify a different AWS profile, the "default" one will be used. Likewise, if you don't specify a region, the region associated with your default profile will be used.
Queries AWS for the latest 64-bit HVM- and EBS-enabled images available for the specified OS distribution. For most distributions, we look for gp2 block devices. Images are returned in reverse chronological order, the most recent being the first listed. usage: ami-search -d distro [-n num] [-p profile] [-r region] [-s] -d specifies distribution [REQUIRED]; currently valid arguments: amazon, amazon2, centos6, centos7, freebsd11, rhel, ubuntu1604, or ubuntu1804 -n the maximum number of results to list. Default is 4. -p specifies a profile in your ~/.aws/credentials file. Uses the default profile if none is specified. -r specifies an AWS region name. The default value for the profile you use is found in your ~/.aws/config file. -s will return only AMI image id. Default is to return image id, creation date, and image description.
These examples are from January 2018. The AMI ID numbers are region-specific and change over time, so you can expect to see different IDs when you run the script.
