Requirements

1. Ansible installed:

sudo apt install python3
python3 -m ensurepip --upgrade
pip3 install ansible

Required variables

Review the variables as shown in defaults.

ssh_keygen_storagedir: "~/.ssh" # where to save generated key
ssh_keygen_keyname: "ed25519" # filename of key
ssh_keygen_cipher: "ed25519" # passed to -t, values are dsa | ecdsa | ecdsa-sk | ed25519 | ed25519-sk | rsa
ssh_keygen_cipher_options: "" # cipher options addtional args to pass when generating keys
ssh_keygen_comment: "" # Comment to set in the key
ssh_keygen_passphrase: "" # Optionally pass a passphrase to generated key (to not prompt for one)

Example playbook

hosts:
  - foo
roles:
  - pimvh.ssh_keygen

TLDR - What will happen if I run this

• Generate ssh key
• Add public key as fact

Future Improvements

• Add variable assertions
• Use community library instead for key generation
