msg: Failed to find required executable pip when installing nginx on coreos

[haozhenxiao]

I'm following this tutorial to install nginx on coreos with ansible, on coreos, python is located at /home/core/bin, and my inventory looks like below:

[coreos]
10.11.49.207

[coreos:vars]
ansible_ssh_user=core
ansible_python_interpreter="PATH=/home/core/bin:$PATH python"

My yml file looks like this:

- name: example nginx website
hosts: coreos
sudo: true
tasks:
- name: Start etcd
  service: name=etcd.service state=started

- name: Install docker-py
  pip: name=docker-py

- name: pull container
  raw: docker pull nginx:1.7.1

- name: launch nginx container
  docker:
    image="nginx:1.7.1"
    name="example-nginx"
    ports="8080:80"
    state=running

when running the yml file, I got the following error:

msg: Failed to find required executable pip

FATAL: all hosts have already failed -- aborting

Hi @haozhenxiao, the pip module has supported specifying the pip executable location since 1.3: http://docs.ansible.com/ansible/pip_module.html. I'd suggest you use that, as pip is in a non-standard location outside of the $PATH environment.

If you have any further questions, please let us know by stopping by one of the two mailing lists, as appropriate:

• https://groups.google.com/forum/#!forum/ansible-project - for user questions, tips, and tricks
• https://groups.google.com/forum/#!forum/ansible-devel - for strategy, future planning, and questions about writing code

Because this project is very active, we're unlikely to see comments made on closed tickets, but the mailing list is a great way to ask questions, or post if you don't think this particular issue is resolved.

Thank you!
