Ansible Docker node

Cloud provider agnostic automation for provisioning node with Docker daemon.

Prerequisites

• ansible
• Run make install-roles

Provision VM

Use your favourite cloud and create instance with Ubuntu 20.04 Don't forget to:

• configure ssh keys
• obtain public IP address

Create inventory file

touch inventory/inventory

For the first run you propbably will have something like this:

[all]
docker-0 ansible_host=12.34.56.78 ansible_port=22 ansible_user=ubuntu

Run playbook

ansible-playbook -vv -i inventory/inventory playbooks/docker.yml

Test

With default variables you can connect like:

ssh 12.34.56.78 -l ansible -p 2345

Update inventory file for new user

Ansible created ssh user, changed sshd ports and etc, so we need to update inventory file for next runs:

[all]
docker-0 ansible_host=12.34.56.78 ansible_port=2345 ansible_user=ansible
