Updated Apr 5 2019:

because this is a gist from 2011 that people stumble into and maybe you should AES instead of 3DES in the year of our lord 2019.

I just had to set up Jenkins to use GitHub. My notes (to myself, mostly):

Detailed Instructions

For setting up Jenkins to build GitHub projects. This assumes some ability to manage Jenkins, use the command line, set up a utility LDAP account, etc. Please share or improve this Gist as needed.

Install Jenkins Plugins

• get both the git and github plugin
• http://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin

vault_aws_auth

These are python 2 and 3 snippets showing how to generate headers to authenticate with HashiCorp's Vault using the AWS authentication method. There's also a Ruby implementation which uses version 3 of the AWS SDK for Ruby.

The python scripts look for credentials in the default boto3 locations; if you need to supply custom credentials (such as from an AssumeRole call), you would use the botocore.session.set_credentials method before calling create_client.
