Deployment scripts for OpenWeaver.

6 node types:

• Monitoring - Elasticsearch instance which aggregates logs from other nodes.
• Beacon - Acts as a bootstrap node to discover other nodes in the network
• Master, Relay - Form the propagation network
• Bridge - Acts as a gateway between Eth network and our propagation network. Needs to be added as a peer to the Eth full node.
• Eth - Eth full node which is the only publicly exposed component, prevents spam

Bridge and Eth are usually deployed in a single instance.

The repo has a lot of legacy scripts. Current ones are in the provisioning, deployment and stacks folders.

1. Navigate to stacks/katara.
2. Provision instances using pulumi up. Can change numbers/regions/config in index.ts.
3. Configure ansible inventory. An example is given in inv.gcp.yml.example to automatically configure inventory from running instances on GCP. It needs an env var GCP_SERVICE_ACCOUNT_FILE pointing to a service account file path (Ref: https://docs.ansible.com/ansible/latest/scenario_guides/guide_gce.html).
4. Configure ansible variables needed for various playbooks. An example is given in ansiblevars.yml.example.
5. Key scan instances to mark them as known hosts.

ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" monitoring/monitoring.yml --tags=keyscan
ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" beacon/beacon.yml --tags=keyscan
ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" master/master.yml --tags=keyscan
ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" relay/relay.yml --tags=keyscan
ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" msggen/msggen.yml --tags=keyscan

6. Gather monitoring and beacon IPs which are used in other playbooks.

ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" monitoring/monitoring.yml --tags=gather
ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" beacon/beacon.yml --tags=gather

7. Deploy the various nodes

ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" monitoring/monitoring.yml
ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" beacon/beacon.yml
ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" master/master.yml
ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" relay/relay.yml
ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" msggen/msggen.yml

Notes:

• monitoring.yml has a task to automatically provision a HTTPS certificate for the given domain. This needs DNS to be preconfigured to point to the monitoring instance before running.
• msggen.yml has a task tagged with chaindata which downloads chaindata from an existing GCS bucket to save sync time. It can be run (while geth isn't running) using

ansible-playbook -i inv.gcp.yml -e "@ansiblevars.yml" msggen/msggen.yml --tags=chaindata
