Send data from Google Compute Engine to Google Pub/Sub using Ansible

[Jam Volkov]

I would like to send data from Google vm instance to Google Pub/Sub using Ansible.

Ansible playbook

--- 
- hosts: localhost 
  tasks: 
  
  - name: Write into log file 
    local_action: 
      shell echo "Hello" >> /etc/ansible/log.txt 

  - name: Send message through pubsub 
    shell: python pub.py project-344421 topic_test 
    args: 
      chdir: /home/pubsub 

Error

    "msg": "non-zero return code", 
    "rc": 1, 
    "start": "2020-04-14 18:20:00.723265", 
    "stderr": "Traceback (most recent call last):\n  File \"pub.py\", line 22, in <module>\n    from google.cloud import pubsub_v1\nImportError: No module named google.cloud", 
    "stderr_lines": [
        "Traceback (most recent call last):", 
        "  File \"pub.py\", line 22, in <module>", 
        "    from google.cloud import pubsub_v1", 
        "ImportError: No module named google.cloud"
    ], 
    "stdout": "", 
    "stdout_lines": []

 Manually, the script pub.py runs properly with python pub.py project-344421 topic_test

 Output

The modules google.cloud, google-cloud-pubsub and google-auth are installed

pip install --upgrade google-cloud
pip install --upgrade google-cloud-pubsub
pip install --upgrade google-auth

 The executable path is different from the module location path. So I worked with virtualenv and it's ok now.
