How to attach ports to a machine on openstack

openstack-attach-ports-to-machine.sh

primary_subnet=PRD_APPLIS
secondary_subnet=ADM_APPLIS
primary_network=port_opsman01_I_PRD_APPLIS
secondary_network=port_opsman01_I_ADM_APPLIS
virtmachine=opsman01


#show a Default port
neutron port-show $primary_network

#show a Second port
neutron port-show $secondary_network


#Create ports
neutron port-create --name $primary_network --fixed-ip subnet_id=$primary_subnet,ip_address=10.110.148.10 $primary_subnet

neutron port-create --name $secondary_network --fixed-ip subnet_id=$secondary_subnet,ip_address=10.233.122.10 $secondary_subnet

# Get the network IDs
default_network_id=$(neutron port-show $primary_network -f json | jq '.id' |tr -d '"')

second_network_id=$(neutron port-show $secondary_network -f json | jq '.id' |tr -d '"')

# Attach ports to the VM
nova interface-attach --port-id=$default_network_id $virtmachine
nova interface-attach --port-id=$second_network_id $virtmachine

# start the vm
nova start $virtmachine

# You also probably need to set the openstack security group to the vm.
