MGMT-22968: Add infrastructure-only mode and Landing Zone VM support #1846
Conversation
This commit adds a new 'infra_only' Makefile target and support for
Landing Zone VMs to dev-scripts. This enables users to create
baremetal-like test infrastructure (VMs, networks, BMC emulation)
without deploying an OpenShift cluster.
Changes:
1. New 'infra_only' Makefile target
- Runs 'requirements' and 'configure' steps only
- Stops before cluster deployment (build_installer, ironic, etc.)
- Useful for testing external deployment tools (GoRI Lab, custom installers)
2. Landing Zone VM support
- Added NUM_LANDINGZONE environment variable (default: 0)
- Added landingzone flavor with configurable specs:
* LANDINGZONE_MEMORY (default: 8192 MB)
* LANDINGZONE_DISK (default: 60 GB)
* LANDINGZONE_VCPU (default: 4)
- Landing Zone VM acts as deployment host with dual network access
3. Network topology fix for Landing Zone use case
- Worker VMs: cluster network only (BMC network removed)
- Landing Zone VM: both BMC and cluster networks
- Ensures proper network isolation for testing scenarios
- Only applies when NUM_LANDINGZONE > 0
4. Documentation updates
- Added "Infrastructure-Only Mode" section to README
- Added "Deploying with Landing Zone VMs" section to README
- Documented network topology and use cases
Use case: Testing external deployment tools that need infrastructure
without cluster deployment, such as GoRI Lab for bare metal OpenShift
installations.
Backward compatibility: All existing targets (default, agent, assisted)
work unchanged. New variables default to 0 (no Landing Zone VMs).

/approve AFAIK what you call "landing zone vm" is called "bastion host" and "landing zone" itself is "everything in my cloud subscription what can possibly interact with each other. But it's just a naming so whatever works for you, works |
