Ansible playbook for setting up VM before deploying Onedata services

Prerequisites

  • ssh access from the VM where ansible playbook is run to other nodes
  • python3 on all nodes

ansible-vm

  • python3
  • ansible >=2.8.4
  • jinja2 <3.10
  • jmespath

The requirements can be installed like the following:

sudo apt install -y python3 python3-pip
sudo python3 -m pip install ansible "Jinja2>=2.10,<3.1" jmespath

Configuring

Preparing hosts (Ansible inventory file)

Place your node names and IP addresses into hosts. See the comments for example lines.

Configuring variables

Edit group_vars/all.yml. The semantics of variables is explained in the comments.

Configuring SSH connections

Make sure all nodes are reachable with SSH from the ansible host and the public key (of the user running the ansible) is added.

When running for a localhost node, one of the ways is to do this:

ssh-keygen -b 2048 -t rsa -f ~/.ssh/id_rsa -q -N ""  # if not generated yet
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

or to use ssh-agent.

Running the playbook

ansible-playbook -i hosts site.yml
