Background

When using Ansible, to avoid the need to enter the SSH password each time a task is executed, we can cache the SSH key.

Caching SSH Keys with Ansible

1. Start the ssh-agent background program

eval “$(ssh-agent -s)”

2. Add the key to ssh-add, only input the password once

ssh-add ~/.ssh/xxx

3. Verify if the key is successfully cached

ssh-add -l
