【问题描述】:
我曾尝试使用 ansible-local 在 vagrant VM 中创建虚拟环境,但失败了。
这是我的 Vagrant 文件:
Vagrant.configure(2) do |config|
config.vm.provider "virtualbox" do |v|
v.memory = 4096
v.cpus = 2
end
config.vm.define "shortener" do |shortener|
shortener.vm.box = "ubuntu/trusty64"
# database
shortener.vm.network :forwarded_port, host: 3307, guest: 3306
# browser
shortener.vm.network :forwarded_port, host: 4568, guest: 4568
shortener.vm.provision :ansible_local do |ansible|
ansible.playbook = "playbook.yml"
end
end
config.ssh.forward_agent = true
end
这是“playbook.yml”:
- name: Deploy shortener
hosts: all
become: true
become_method: sudo
tasks:
- name: Install packages
apt: update_cache=yes name={{ item }} state=present
with_items:
- git
- python-pip
- nginx-full
- vim
- python-virtualenv
- virtualenvwrapper
- python3.4
- python3.4-doc
- python3.4-dev
- software-properties-common
- python-software-properties
- postgresql
- postgresql-client
- name: Load virtualenvwrapper
shell: source /etc/bash_completion.d/virtualenvwrapper
- name: Create virtual environment
shell: mkvirtualenv shortener --python=/usr/bin/python3
- name: Install requirements
pip: requirements='/vagrant/configs/requirements.txt'
这是'vagrant up'的输出:
hedin@home:~/url_shortener$ vagrant provision
==> shortener: Running provisioner: ansible_local...
shortener: Running ansible-playbook...

我还尝试使用“command”而不是“shell”,结果相同。
我想我可以使用创建虚拟环境的 shell 脚本,但是是否可以通过 ansible 方法修复该错误?
【问题讨论】:
-
pip模块支持virutalenv参数,因此您不需要在单独的任务中执行此操作 (docs)。 -
我认为你的问题的根源可能是当你获取你的 python virtualenv 时:)。我通常在我的剧本中使用来自 virtualenv 的
python二进制文件的完整路径,而不是采购 virtualenv。也许如果您使用mkvirtualenv的完整路径,它会起作用。 -
@notorious.no 我不确定“mkvirtualenv 的完整路径”是什么意思,因为它只是“
virtualenvwrapper.sh”中的一个函数。
