So Now you are connected to your remote hosts and you can start automating and writing playbooks. "discovered_interpreter_python": "/usr/bin/python" ⇒ ansible -m ping prodservers -i ansible_hosts 2>/dev/null If all goes well I can see the pong response from each remote hosts.
I am going to use the ansible ping module to test the connecvity. you can go ahead execute some commands like ping to test your SSH connection Private_key_file = /Users/laptopuser/.ssh/id_rsaĪnsible_ssh_common_args='-o StrictHostKe圜hecking=no -o Prox圜ommand="ssh -o \'ForwardAgent yes\' -p 2222 \'ssh-add /home/sarav/.ssh/id_rsa & nc %h %p\'"'Īnd That’s all, rest is as usual. We have given an explanatory image below and explained each arguments and their purpose.įor easy copying and to not mis-interpret the quotes, I have given the same as a plain text below. Let us see the arguments we are passing for the ansible_ssh_common_args in detail here. This image would help you understand it little better. There we are defining the SSH username for the bastion to ec2 servers which is ubuntu in my caseĪlso I define the port to use for SSH, in my case it is 2222 Here is the quick image of my inventory file, I have a hostgroup named prodservers and am defining some variables using prodservers:vars definition Like anyother Ansible prerequisites we need to define our hosts under the hostgroup in the inventory file. So we are using two different keys here for enabling the SSH communication from my Laptop to the remote EC2 instances or hosts.Īnsible hosts file changes to use Bastion ( you can think of it as any regular linux ) We are going to login to Bastion with our key and from there we would be using a different key to login to our EC2 linux instances. Ansible hosts file changes to use Bastion.
#Ssh proxy command aws bastion host how to
Our Objective for this article is to talk about how to use Bastion host or Jump host as a medium and connect to our remote hosts. Read more about ProxyJump here in this article or SSH Forwarding in the technical terminologies. This Process is also known as ProxyJump in latest SSH versions. With SSH Forwarding machanism its possible you can login to the remote server directly by using the Bastion as a tunnell. For security reasons, we will first login to the Jump Server also known as Bastion host.
When it comes to Enterprises we do not directly connect from our laptop (mac/windows) to the servers. In General, We know it is a an easy job to connect to remote hosts from Ansible control machine ( where you execute ansible playbook and ad hoc commands ) as it is agent lessĪs long as we have SSH Connectivity we are good. In this article we are going to see how to connect to remote hosts using Bastion host or Jump Server for Ansible playbook or Adhoc command execution.
