如何在剧本上设定ansible促分裂原策略？

Question

I'm trying to make it work mitogen strategy on my ansible playbook. I'm following tutorial on mitogen tutorial . My python version is 3.6 and ansible version is 2.7.10.

Mitogen is installed in /usr/local/lib/python3.6/site-packages/ansible_mitogen/plugins/strategy

When I try to add keys on my playbook as:

  - hosts: "{{ host_group | default('host-list') }}"
    ...
    strategy: mitogen_linear
    strategy_plugins: /usr/local/lib/python3.6/site-packages/ansible_mitogen/plugins/strategy

I have the following error:

ERROR! 'strategy_plugins' is not a valid attribute for a Play

Also, I'm trying to configure it as a environment variable in playbook execution:

command = ['ANSIBLE_STRATEGY_PLUGINS=/usr/local/lib/python3.6/site-packages/ansible_mitogen/plugins/strategy', 'ANSIBLE_STRATEGY=mitogen_linear', 'ansible-playbook', '-ihosts', 'ansible_scripts/inventory.yml']
process = subprocess.Popen(command, stdout=subprocess.PIPE)

Here is not finding directory:

FileNotFoundError: [Errno 2] No such file or directory: 'ANSIBLE_STRATEGY_PLUGINS=/usr/local/lib/python3.6/site-packages/ansible_mitogen/plugins/strategy': 'ANSIBLE_STRATEGY_PLUGINS=/usr/local/lib/python3.6/site-packages/ansible_mitogen/plugins/strategy'

How I can correctly configure mitogen strategy on my playbook? How I can make it work?

Answer 1

This might be some misconfiguration "No such file or directory" . Try the configuration file. For example put into the [defaults] section:

$ grep strategy /etc/ansible/ansible.cfg
strategy_plugins = /usr/local/ansible/plugins/ansible_mitogen/plugins/strategy
strategy = mitogen_linear

Fit the configuration file and path to your needs. (Works for me with ansible 2.7.9 and mitogen-0.2.6)

FWIW, if you want to automate the installation and configuration see plugins.yml and example of vars .
