Add or remove a host from the known_hosts file using ansible.
This is especially useful for a new machine where you want to do something like use the 'git' module with ssh. If you don't prime the known_hosts file, ansible will hang because it is waiting for input you can't give it.
How To Use
known_hosts bash script into a library folder adjacent to your ansible playbook. You can then define a task like this:
--- - hosts: myhosts user: deploy tasks: - name: Ensure github is in the known_hosts file known_hosts: host=github.com state=present
Required. The host to add or remove. Will also look up the IP address and add that as well.
The ssh port. Defaults to 22
The known_hosts file to append/remove the keys from. Defaults to $HOME/.ssh/known_hosts
'present' to add the host, 'absent' to remove it. Defaults to 'present'
Username of the owner of 'known_hosts' file, usually useful in case you specified custom filepath in 'file' attribute.
Python is considered good form for Ansible modules, but for now it was much easier to convert something I already had written in bash. It does the job, but I may some day convert it to Python in order to submit it to ansible.cc
