- host_ocp4_agent_installer: Agent-Based Installer for disconnected OCP on Troshka - DNS forwarder extra manifest for registry resolution - Redfish virtual media boot via sushy-emulator - Pull-through registry support for oc-mirror - host_ocp4_ibi_installer: Image-Based Install for SNO rapid deployment - Seed image restore via lca-cli - Recert for cluster identity rename
…lution The DNS forwarder alone isn't enough — OVN/CNI pods need to pull images before CoreDNS starts. /etc/hosts is available at boot and resolves the registry hostname for CRI-O immediately.
Use systemd oneshot service instead of ignition append for /etc/hosts entry. MCO doesn't support ignition 'append' directive — causes 'Append is not supported' error and blocks all MCO reconciliation. The systemd unit runs Before=crio.service so CRI-O can resolve the registry hostname at boot, before CoreDNS starts.
- Break long URL lines (>150 chars) in IBI main.yml, eject_iso.yml, and agent installer main.yml using folded scalars and extracted variables - Fix name[template] violations: move Jinja expressions to end of task names - Add troshka.cloud.project_info to mock_modules in .ansible-lint - Copy boot_via_bmc.yml and eject_iso.yml into host_ocp4_ibi_installer role to resolve load-failure[filenotfounderror] from relative includes
