+## SSH keys forwarding
+
+If you run Ansible with SSH-keys-based authentication to avoid authentication prompts, use `ssh-agent` to forward the SSH keys to your EE:
+
+``` bash
+eval $(ssh-agent)
+ssh-add </path/to/your/private/key>
+```
+
+To test the above playbook, add the `remote_user: <your_ssh_user>` field to the play and then run:
+
+``` bash
+ansible-navigator run test_remote.yml -i inventory --execution-environment-image postgresql_ee:latest --mode stdout --pull-policy missing
+```
