openssh-iam-ssh-public-key
This is a tiny program that retrieves registered SSH public keys for a specified IAM user and prints them to standard output.
Synopsis
$ openssh-iam-ssh-public-key -user [USER]
-user option can be omitted, and output the keys for all the users then.
Configuration
In addition to the default AWS SDK configuration scheme, it supports STS credentials for a assumed role through the following environment variables:
-
AWS_STS_SOURCE_PROFILEThis specifies the AWS profile in ~/.aws/config used for retrieving temporary credentials.
-
AWS_STS_ASSUME_ROLE_ARNThis specifies the ARN for the assumed (target) IAM role.
This program is particularly useful if you have the following setting in /etc/ssh/sshd_config:
AuthorizedKeysCommand openssh-iam-ssh-public-key -user %u
which enables one whose unix account name corresponds to an IAM user to get authenticated through the SSH keys associated in IAM.
