I am running ansible in a local virtualenv and I want to execute the setup action on remote docker hosts.
When running the setup action normally, the boot command uses /usr/bin/python. However when I run the setup action with the delegate_to option then it wants to use the python interpreter from the local virtualenv (which of course does not exist on the remote docker host).

Ansible version:

ansible 2.6.5
  config file = None
  configured module search path = [u'/Users/Pieter/library']
  ansible python module location = /Users/Pieter/.local/share/virtualenvs/it-4glgr_h9/lib/python2.7/site-packages/ansible
  executable location = /Users/Pieter/.local/share/virtualenvs/it-4glgr_h9/bin/ansible
  python version = 2.7.14 (default, Nov  2 2017, 16:04:18) [GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.42.1)]

Also tested on 2.7.0, with the same result.

Ansible config dump:

DEFAULT_CALLBACK_PLUGIN_PATH(env: ANSIBLE_CALLBACK_PLUGINS) = [u'/Users/Pieter/.local/share/virtualenvs/it-4glgr_h9/lib/python2.7/site-packages/ara/plugins/callbacks']
DEFAULT_FILTER_PLUGIN_PATH(env: ANSIBLE_FILTER_PLUGINS) = [u'/Users/Pieter/filter_plugins']
DEFAULT_MODULE_PATH(env: ANSIBLE_LIBRARY) = [u'/Users/Pieter/library']
DEFAULT_MODULE_UTILS_PATH(env: ANSIBLE_MODULE_UTILS) = [u'/Users/Pieter/library/utils']
DEFAULT_STRATEGY_PLUGIN_PATH(env: ANSIBLE_STRATEGY_PLUGINS) = [u'/Users/Pieter/Git/github/dw/mitogen/ansible_mitogen/plugins/strategy']
DEFAULT_TEST_PLUGIN_PATH(env: ANSIBLE_TEST_PLUGINS) = [u'/Users/Pieter/test_plugins']

Using the current git master of mitogen (ad44ad1).

Local OS: Mac OS X 10.13.6
Remote OS: Red Hat 7.5 remote docker containers.

Local Python: 2.7.14
Remote Python: 2.7.6

Example test playbook:

- hosts: host1
  gather_facts: false
    - name: Gather facts
        gather_subset: '!all,!min,network'
    - name: Gather facts delegated
        gather_subset: '!all,!min,network'
      delegate_to: host2
      delegate_facts: true

I see the following output (using -vvv):
