5. Update VNF

Create vnf-config.yaml:

vdus:
  VDU1:
    config:
      foo: 'bar'

Update VNF with the config file vnf-config.yaml:

$ openstack vnf set --config-file vnf-config.yaml <VNF: vnf-scale>

                        <VNF>

Update a given VNF.

positional arguments:
  <VNF>                 VNF to update (name or ID)

optional arguments:
  -h, --help            show this help message and exit
  --config-file CONFIG_FILE

  --param-file PARAM_FILE
                        YAML file with VNF parameter

Note

When the update VNF operation executed, Tacker ask Heat to update the stack and the change is reflected immediately, and the VMs may reboot.

6. Scale VNF

Scale out the VNF:

$ openstack vnf scale --scaling-policy-name <SCALING_POLICY_NAME: SP1> \
    --scaling-type out <VNF: vnf-scale>

Check the VMs scaled out:
