Ansible playbooks

You need to install vagrant. Then:

python3 -m venv venv
. venv/bin/activate
pip3 install -r requirements.txt

NFS

The app role assumes the directory /var/persistent exists and is owned by the current user.

Celery worker

The celery role assumes that the ansible playbook directory (i.e. this directory) contains:

• icfpcontest2019.jar
• problems/
• blocks/

Run

vagrant up

To run for AWS:

ansible-playbook aws-fleet.yml

AWS Dynamic Inventory

From the contrib folder, copy the ec2.py script to /etc/ansible/hosts and chmod +x it. Also copy ec2.ini to /etc/ansible/ec2.ini.

Create a file cred.sh:

export AWS_ACCESS_KEY_ID='abc123'
export AWS_SECRET_ACCESS_KEY='abc123'

Before running ansible: source cred.sh
