Running ansible playbook in AWS EC2 instance using Jenkins Job from a local PC using ssh-agent

[Raj Boruah]

Hi,    

I am trying to run ansible playbook from jenkins installed in my local PC.    Ansible playbook is available in AWS EC2 instance. I am using ssh-agent plugin in     Jenkins to forward the ssh key but ansible is not able to ssh to EC2 instances.     Appreciate any help on it.    

Here is sample output the Jenkin's job run:

Hi,

Here are a few things I'm thinking of:

1. Have you validated that the key configured in the SSH Agent plugin works for that instance manually?

2. Verify the EC2, Subnet, and VPC are allowing traffic inbound from the Jenkins server to the EC2 instance.

3. Can you SSH from your local machine with the same key in #1 to the EC2 instance?
