Example for Ansible git-module and ssh agent forwarding

gistfile1.sh

# files/env:
Defaults env_keep += "SSH_AUTH_SOCK"

# tasks/main.yml
- name: ensure sudo keeps SSH_AUTH_SOCK in environment
  copy: src=env
        dest=/etc/sudoers.d/env
        mode=0440
        owner=root
        group=root

- name: clone repo from github
  git: repo=ssh://git@github.com/example/example-repo.git
       dest=/tmp/example-repo

# ~/.ssh/config
Host my-remote-ansible-host
    ForwardAgent yes

# Make sure your key is added to ssh-agent

Note that you also have to set "accept_hostkey" for ansible.builtin.git (see https://docs.ansible.com/ansible/latest/collections/ansible/builtin/git_module.html#parameter-accept_hostkey ) for the solution provided by @NorthV

I'm not sure at all why this seems to be necessary

Thanks, the adding a file to /etc/sudoers.d is a much more reassuringly idempotic way compared to editing /etc/sudoers
