   Hi Takamune Cho,

   Is this related to your work ?

   The vFWDT execution is Ok from the workflow.py script to the ansible server. But the ansible server is not able to execute the playbook because there is a wrong argument  ( timeout: unrecognized option: signal=KILL) in ansible server command:

   
   

   Here is the command:

   
   

   timeout --signal=KILL 3600 ansible-playbook -v --timeout 3600 --extra-vars "vnf_instance='vfwdt',
   ConfigFileName='../traffic_distribution_config.json'" -i PlaybooksTemp/vfwdt_5a47fc4e-2cb4-48b5-87cb-229443641204_7dcd
   4e7c-9dff-43c3-bef5-28b1b1276f8f/inventory/vfwdthosts PlaybooksTemp/vfwdt_5a47fc4e-2cb4-48b5-87cb-229443641204_7dcd4e7c
   -9dff-43c3-bef5-28b1b1276f8f/distributetraffic/site.yml
   timeout: unrecognized option: signal=KILL

   
   

   Looking in the AnsibleServer.py, I think the code related to create this command is here:

   
   

   if len(str_parameters) > 0:
   cmd = 'export HOME=/root; env; cd ' + playbookdir + ';' +'timeout --signal=KILL ' + str(timeout) + \
   ' ansible-playbook -v --timeout ' + str(timeout) + ' --extra-vars ' + str_parameters + ' -i ' + \
   inventory_path + ' ' + playbook_path + ' | tee log.file'
   else:
   cmd = 'export HOME=/root; env; cd ' + playbookdir + ';' +'timeout --signal=KILL ' + str(timeout) + \
   ' ansible-playbook -v --timeout ' + str(timeout) + ' -i ' + inventory_path + ' ' + playbook_path +' | tee log.file'

   
   

   In the Jira , I see that you've made the appropriate change to make it run ?

   
   

   https://gerrit.onap.org/r/#/c/ccsdk/distribution/+/77578/1/ansible-server/src/main/ansible-server/AnsibleModule.py

   
   

   But I'm a little by lost to trace all the modified file. What should be the appropriate file to change ?

   
   

   Thanks,

      I did remember there was a syntax error related to KILL signal issue. but I can't recall how I fixed it. what version are you using for ansible container?

      Hi Takamune Cho,

      
      

      Following the 

      https://gerrit.onap.org/r/#/c/ccsdk/distribution/+/77578/1/ansible-server/src/main/ansible-server/AnsibleModule.py

      I changed the lines to generate to cmd.

      if len(str_parameters) > 0:
      cmd = 'export HOME=/opt/ansible-server; env; timeout -s KILL -t ' + str(timeout) + \
      ' ansible-playbook -v --timeout ' + str(timeout) + ' --extra-vars ' + str_parameters + ' -i ' + \
      inventory_path + ' ' + playbook_path + ' | tee log.file'
      else:
      cmd = 'export HOME=/opt/ansible-server; env; timeout -s KILL -t ' + str(timeout) + \
      ' ansible-playbook -v --timeout ' + str(timeout) + ' -i ' + inventory_path + ' ' + playbook_path

      
      

      Now the playbook is executed but I get a different error at the end of the execution ( after checking traffic presence): Here is I can get from the ansible-server.log:

      Have you encountered this before ?

      
      

      On the other hand , to answer your question about the version. I use the following image for the ansible-server:

      image: onap/ccsdk-ansible-server-image:0.4.2

      Thanks for your help
