quickstart

quickstart is the Ansible playbook that deploys an Eru cluster on Ubuntu hosts. It installs three things and wires them together: an etcd cluster that holds all cluster metadata, eru-core as the scheduler in front of it, and eru-agent on every node that runs workloads.

Each inventory group is a role. A host may belong to several groups — the single-node bootstrap puts one host in all three.

Guides

• Installation — requirements, the inventory, running the playbook, and what lands on each host
• Configuration — every variable the playbook reads, and the config files it renders for core and agent
