no /usr/bin/python in RHEL8 - module fails about ansible-sshkeys

[bengland2]

This playbook works, and is sufficient to get user's ssh public key installed without python on the target system. What do you think Will? This seems simple and breaks the dependency trap.

[bengland@localhost ansible-sshkeys]$ cat raw.yml
---
#
# Ansible playbook to manage SSH keys
#

- hosts: servers
  gather_facts: no
  remote_user: root
  vars:
    ssh_public_key_file: ~/.ssh/id_rsa.pub
    ssh_auth_keys: ~/.ssh/authorized_keys
  tasks:
  - name: read default ssh public key
    local_action: command cat "{{ ssh_public_key_file }}"
    register: ssh_public_key

  - name: install public key in target account .ssh/authorized_keys
    raw: "echo {{ ssh_public_key.stdout_lines[0] }} > {{ ssh_auth_keys }}"

  - name: install python so rest of ansible works!
    raw: "dnf install -y python3 && ln -sv /usr/bin/python3 /usr/bin/python"

So for example if I run this:

ansible-playbook --ssh-common-args '-o StrictHostKeyChecking=no'   -i hosts -e ansible_ssh_pass=password raw.yml

Then I can run:

ansible all -u root -i hosts -m shell -a uptime

https://github.com/bengland2/ocp4_upi_baremetal/blob/master/install_public_key.yml solves my problem, so I stopped using this. I think this is a better approach for RHEL8 since it assumes less about the state of the target system. But I haven't tried it for RHEL7.

Closing this (it's quite old). It's not unreasonable to assume Python is present on a remote host and this playbook requires it.
