Ansible playbook to launch a Linode instance and then configure it to run Minecraft. Note that some things are hardwired: the label of the instance, the version of minecraft

README.md

Requires Ansible in this branch ansible/ansible#46151 (until that is merged .. then devel or master)

$ ansible-playbook  /tmp/minecraft_linode.yml  -e linode_token=$LINODE_TOKEN -e ssh_key="$(cat ~/.ssh/id_rsa.pub)" -e type=g6-nanode-1 -e region=us-east -e image=linode/debian9 -e ansible_ssh_private_key_file=~/.ssh/id_rsa --private-key=~/.ssh/id_rsa
 [WARNING]: Unable to parse /etc/ansible/hosts as an inventory source

 [WARNING]: No inventory was parsed, only implicit localhost is available

 [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'

Here is how I've built my host group before to connect to the new Linode:

- name: Dynamically create the Linode connection details.
  add_host:
    hostname: freshly-created-linode
    ansible_user: root
    ansible_host: "{{ linode_creation_details.data.instance.ipv4[0] }}"
    ansible_ssh_pass: "{{ ssh_root_pass }}"
    ansible_ssh_private_key_file: "{{ generated_ssh_key.ssh_key_file }}"
    ansible_ssh_extra_args: '-o StrictHostKeyChecking=no'

Or so, you might try to make sure you pass all of these (if not already) to make the connection.
