Description of problem: The rendered single-nic-linux-bridge-vlans network configs do not work due to bridge_name replacement only affecting first match in /etc/os-net-config/config.json Version-Release number of selected component (if applicable): openstack-tripleo-heat-templates-11.3.2-0.20200616081532 How reproducible: always Steps to Reproduce: 1. run process-templates.py 2. use configs from network/config/single-nic-linux-bridge-vlans/ 3. deploy overcloud Actual results: devices in config.json use "device:" "bridge_name" instead of "device:" "br-ex" {"network_config": [{"name": "eno1", "type": "interface", "use_dhcp": false}, {"name": "eno2", "type": "interface", "use_dhcp": false}, {"name": "eno3", "type": "interface", "use_dhcp": false}, {"name": "eno4", "type": "interface", "use_dhcp": false}, {"addresses": [{"ip_netmask": "10.255.0.7/24"}], "dns_servers": ["10.31.20.13", "10.242.67.11", "10.247.139.253"], "domain": ["example.com"], "members": [{"bonding_options": "miimon=100 mode=4 xmit_hash_policy=layer3+4", "members": [{"mtu": 9000, "name": "enp6s0f0", "primary": true, "type": "interface"}, {"mtu": 9000, "name": "enp6s0f1", "type": "interface"}], "mtu": 9000, "name": "bond1", "type": "linux_bond"}, {"addresses": [{"ip_netmask": "10.255.2.7/24"}], "device": "br-ex", "mtu": 9000, "routes": [], "type": "vlan", "vlan_id": 2478}, {"addresses": [{"ip_netmask": "172.18.0.7/23"}], "device": "bridge_name", "mtu": 1500, "routes": [], "type": "vlan", "vlan_id": 2472}, {"addresses": [{"ip_netmask": "172.18.4.7/23"}], "device": "bridge_name", "mtu": 9000, "routes": [], "type": "vlan", "vlan_id": 2473}, {"addresses": [{"ip_netmask": "10.247.152.7/27"}], "device": "bridge_name", "mtu": 1500, "routes": [], "type": "vlan", "vlan_id": 2471}], "name": "bridge_name", "routes": [{"default": true, "next_hop": "10.255.0.1"}], "type": "linux_bridge", "use_dhcp": false}]} Expected results: devices use "device:" "br-ex" (or whatever NeutronPhysicalBridge is) {"network_config": [{"name": "eno1", "type": "interface", "use_dhcp": false}, {"name": "eno2", "type": "interface", "use_dhcp": false}, {"name": "eno3", "type": "interface", "use_dhcp": false}, {"name": "eno4", "type": "interface", "use_dhcp": false}, {"addresses": [{"ip_netmask": "10.255.0.7/24"}], "dns_servers": ["10.31.20.13", "10.242.67.11", "10.247.139.253"], "domain": ["example.com"], "members": [{"bonding_options": "miimon=100 mode=4 xmit_hash_policy=layer3+4", "members": [{"mtu": 9000, "name": "enp6s0f0", "primary": true, "type": "interface"}, {"mtu": 9000, "name": "enp6s0f1", "type": "interface"}], "mtu": 9000, "name": "bond1", "type": "linux_bond"}, {"addresses": [{"ip_netmask": "10.255.2.7/24"}], "device": "br-ex", "mtu": 9000, "routes": [], "type": "vlan", "vlan_id": 2478}, {"addresses": [{"ip_netmask": "172.18.0.7/23"}], "device": "br-ex", "mtu": 1500, "routes": [], "type": "vlan", "vlan_id": 2472}, {"addresses": [{"ip_netmask": "172.18.4.7/23"}], "device": "br-ex", "mtu": 9000, "routes": [], "type": "vlan", "vlan_id": 2473}, {"addresses": [{"ip_netmask": "10.247.152.7/27"}], "device": "br-ex", "mtu": 1500, "routes": [], "type": "vlan", "vlan_id": 2471}], "name": "br-ex", "routes": [{"default": true, "next_hop": "10.255.0.1"}], "type": "linux_bridge", "use_dhcp": false}]} Additional info: Issue is due to sed run-os-net-config.sh only replacing first match in line: sed -i "s/: \"bridge_name/: \"${bridge_name:-''}/" /etc/os-net-config/config.json adding 'g' to the substitute resolves this issue.
