HW virtualization task is not skipped for Kubernetes, causing the deployment/run to fail.

ISSUE TYPE

• Bug Report

COMPONENT NAME

• Ansible

ANSIBLE VERSION

ansible 2.9.4
  config file = /home/ubuntu/express/ansible.cfg
  configured module search path = [u'/home/ubuntu/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.12 (default, Oct  8 2019, 14:14:10) [GCC 5.4.0 20160609]

CONFIGURATION

ANSIBLE_NOCOWS(/home/ubuntu/express/ansible.cfg) = True
ANSIBLE_PIPELINING(/home/ubuntu/express/ansible.cfg) = True
COMMAND_WARNINGS(/home/ubuntu/express/ansible.cfg) = False
DEFAULT_CALLBACK_WHITELIST(/home/ubuntu/express/ansible.cfg) = [u'profile_roles']
DEFAULT_HOST_LIST(/home/ubuntu/express/ansible.cfg) = [u'/home/ubuntu/express/inventory/hosts']
DEPRECATION_WARNINGS(/home/ubuntu/express/ansible.cfg) = False
HOST_KEY_CHECKING(/home/ubuntu/express/ansible.cfg) = False
RETRY_FILES_ENABLED(/home/ubuntu/express/ansible.cfg) = False

OS / ENVIRONMENT

• Ubuntu 16.04.6 LTS

STEPS TO REPRODUCE

1. Populate inventory hosts file with only Kubernetes hosts.

##
## Ansible Inventory
##
[all]
[all:vars]
ansible_ssh_private_key_file = ~/k8s.pem
ansible_become = True
ansible_user=ubuntu

################################################################################################
## Kubernetes Groups
################################################################################################
[pmk:children]
k8s_master
k8s_worker
## global variables defined in group_vars/containervisors.yml
## note: if the following variables are not defined, their tasks will be skipped
##   - cluster_uuid
[k8s_master]
master-0 ansible_host=172.20.34.152
master-1 ansible_host=172.20.34.138
master-2 ansible_host=172.20.34.136
[k8s_worker]
worker-0 ansible_host=172.20.34.137
worker-1 ansible_host=172.20.34.144

2. Execute the pf9-express script, specifying only PMK.

# ./pf9-express -a pmk

EXPECTED RESULTS

• HW virtualization support task would be skipped; it is not needed for K8s.
