Ansible deploy to Kubernetes fails at final step

[mcdg]

Hi,

I'm using Ansible to deploy an application to a Kubernetes cluster. I followed all the steps listed in the official Ansible docs at: https://docs.ansible.com/ansible-container/deploy_kubernetes.html#deployment. My Ansible versions and kubectl versions plus all other dependencies are as they would be if all steps in the docs were followed.

All steps were successful until the final step, which failed with Error 1 below. I 'fixed' this error by copying the library *.py files from example/ansible/roles/example-kubernetes/library/*.py to container/shipit/kubernetes/modules/*.py. This then gave me Error 2. I guess I'm missing some library but I can't figure out which one. Any help much appreciated.

Error 1

[ibmcloud@mcdg-centos-71939519 ansible]$ ansible-playbook shipit-kubernetes.yml -e "playbook_debug=true"

 [WARNING]: provided hosts list is empty, only localhost is available

ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/home/ibmcloud/ansible-container/example/ansible/roles/example-kubernetes/tasks/main.yml': line 2, column 3, but may

be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

- kube_service:

  ^ here

This has been resolved. Apologies for the delay. Turns out that if you installed Ansible Container using pip, the Ansible modules were not installed, and thus there was nothing to copy into the library directory. The fix is in the latest code found in the *develop* branch. 

You can install it using the following: 

pip install --upgrade  git+https://github.com/ansible/ansible-container.git

Or, clone the repo and run setup as described in the Installation Guide. 

Please, let me know, if you are unable to get it working or encounter additional issues.
