I had successfully installed Ironic Service in Tripleo Train, Ussuri Release with the help of openstack discuss team members.

I had custom network configuration for which I had passed Service net map as below in network-environment file.

parameter_defaults:
  ServiceNetMap:
    IronicApiNetwork: oc_provisioning
    IronicNetwork: oc_provisioning

But with the Wallaby Release, since the deployment format has changed There is no network-environment file.

So I tried passing it in a separate environment.yaml file along with the templates.

Command to deploy  in wallaby:

openstack overcloud deploy --templates \
    --networks-file /home/stack/templates/custom_network_data.yaml \
    --vip-file  /home/stack/templates/custom_vip_data.yaml \
    --baremetal-deployment  /home/stack/templates/overcloud-baremetal-deploy.yaml --deployed-server \
    --network-config \
    -e /home/stack/templates/environment.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/services/ironic-conductor.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/services/ironic-inspector.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/services/ironic-overcloud.yaml \
    -e /home/stack/templates/ironic-config.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/services/ptp.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/docker-ha.yaml \
    -e /usr/share/openstack-tripleo-heat-templates/environments/podman.yaml \
    -e /home/stack/containers-prepare-parameter.yaml

Without Service Net Map, deployment was successful but TFTP of image was an issue since we are going with custom network approach.

Passing Service Net map details in a seperate file environment.yaml, is giving the below error:
