问题描述
是否有更好的方法在远程机器上的 virtualenv 中运行 ansible?
Is there a better way to run ansible inside a virtualenv on the remote machines?
到目前为止,我看到的方法是手动或使用 ansible 本身修改 .bashrc 文件.
So far the way I can see is to modify the .bashrc file, manually or with ansible itself.
例如:
tasks:
- name: "Enable virtualenv in .bashrc"
lineinfile: dest=.bashrc
line="source {{ PROJECT_HOME }}/venv/bin/activate"
#
# Put tasks that rely on this precondition here (?)
#
# Optionally, disable this later on
- name: "Disable virtualenv in .bashrc"
lineinfile: dest=.bashrc
line="source {{ PROJECT_HOME }}/venv/bin/activate"
state=absent

推荐答案
这是一种为整个游戏启用 virtualenv 的方法;这个例子在一次游戏中构建了 virtualenv,然后开始使用它.
Here's a way to enable the virtualenv for an entire play; this example builds the virtualenv in one play, then starts using it the next.
不确定它有多干净,但它有效.我只是在 mikepurvis 在这里提到的内容的基础上进行了一些构建.
Not sure how clean it is, but it works. I'm just building a bit on what mikepurvis mentioned here.

# Build virtualenv
- hosts: all
vars:
PROJECT_HOME: "/tmp/my_test_home"
ansible_python_interpreter: "/usr/local/bin/python"
tasks:
- name: "Create virtualenv"
shell: virtualenv "{{ PROJECT_HOME }}/venv"
creates="{{ PROJECT_HOME }}/venv/bin/activate"
- name: "Copy virtualenv wrapper file"
synchronize: src=pyvenv
dest="{{ PROJECT_HOME }}/venv/bin/pyvenv"
# Use virtualenv
- hosts: all
vars:
PROJECT_HOME: "/tmp/my_test_home"
ansible_python_interpreter: "/tmp/my_test_home/venv/bin/pyvenv"
tasks:
- name: "Guard code, so we are more certain we are in a virtualenv"
shell: echo $VIRTUAL_ENV
register: command_result
failed_when: command_result.stdout == ""
pyenv 包装文件:
pyenv wrapper file:
#!/bin/bash
source "$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )/activate"
python $@
