ovirt-api-simulator

Stateful laboratory simulator for the oVirt / RHV Engine REST API. Use it to test API clients and infrastructure tooling without a real Engine or hypervisors.

Lab only. This is not a production Engine, does not run hypervisors, and ships with default credentials plus a self-signed TLS certificate. Do not expose it to untrusted networks.

The simulator is backed by PostgreSQL, driven by generated Engine contract packs, and exposes the same /ovirt-engine/api and SSO OAuth2 surfaces as oVirt Engine. Semantic handlers persist mutations; long-running work is tracked as Engine jobs.

Web UI

Interactive console with endpoint catalog, Engine-shaped Try-it bodies, series hot-swap, and seed data drawers.

Quick start (development checkout)

cp .env.example .env
make up
make seed          # or: make seed-small|seed-large|seed-big

Surface	URL
Web UI console	http://127.0.0.1:5000
Engine API	https://127.0.0.1/ovirt-engine/api

Only two host ports are published by default: Engine 443 and UI 5000. Override with OVIRT_ENGINE_PORT / OVIRT_UI_PORT if those are taken.

Credentials: admin@internal / secret
Also: ops@internal, developer@internal, demo@internal / secret

# OAuth password grant
curl -k -X POST https://127.0.0.1/ovirt-engine/sso/oauth/token \
  -d 'grant_type=password&username=admin@internal&password=secret&scope=ovirt-app-api'

# List VMs (HTTP Basic)
curl -k -u 'admin@internal:secret' -H 'Accept: application/json' -H 'Version: 4' \
  https://127.0.0.1/ovirt-engine/api/vms

Requires this repository checkout (gateway TLS certs and nginx config are bind-mounted):

docker compose -f docker-compose.release.yml up -d
docker compose -f docker-compose.release.yml run --rm --entrypoint python \
  simulator -m app.ovirt.seed_cli --profile minimal

curl -skf https://127.0.0.1/health/ready
curl -k -u 'admin@internal:secret' -H 'Accept: application/json' -H 'Version: 4' \
  https://127.0.0.1/ovirt-engine/api/vms

Or: make release-up && make release-seed PROFILE=minimal
