Question

我使用Ansible playbook来管理Docker容器的安装。我有以下剧本，安装Cassandra：

我想在本地运行此playbook，并将其安装到Boot2Docker中。我可以使用this answer：

中的说明SSH到Boot2Docker

$ ssh -i $HOME/.ssh/id_boot2docker -p 2022 docker@localhost
                        ##        .
                  ## ## ##       ==
               ## ## ## ##      ===
           /""""""""""""""""\___/ ===

Boot2Docker version 1.4.1, build master : 86f7ec8 - Tue Dec 16 23:11:29 UTC 2014
Docker version 1.4.1, build 5bc2ff8
docker@boot2docker:~$

我使用相同的SSH设置创建了一个库存文件：

[local]
localhost ansible_ssh_port=2022 ansible_ssh_user=docker ansible_ssh_private_key_file=~/.ssh/id_boot2docker

但是当我运行剧本时，它失败并出现错误＆＃34; /bin/sh: /usr/bin/python: not found＆＃34;：

$ ansible-playbook db-setup.yml -i hosts.local

即使＆＃34;收集事实＆＃34;我仍然会收到错误。被关闭了。如果我通过SSH连接到Boot2Docker，我可以看到/usr/bin/python存在：

$ ssh -i $HOME/.ssh/id_boot2docker -p 2022 docker@localhost
... 
docker@boot2docker:~$ which python

Answer 1

boot2docker ssh "tce-load -w -i python.tcz"也可以解决这个问题（你需要互联网;-)）对于docker和ansible你需要“docker-py”

设置点，登录boot2docker
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
pip install docker-py

还会添加到您的广告资源文件中：

dockerhost ansible_connection=ssh ansible_ssh_host=192.168.59.103 ansible_ssh_user=docker ansible_ssh_private_key_file=~/.ssh/id_boot2docker ansible_python_interpreter=/usr/local/bin/python

Answer 2

解决方案很简单：Boot2Docker默认不安装Python。

要安装，请运行

$ boot2docker ssh "wget http://www.tinycorelinux.net/6.x/x86/tcz/python.tcz && tce-load -i python.tcz && rm -f python.tcz"

我创建了一个自动执行此操作的脚本，请参阅 https://gist.github.com/bcattle/90e64fbe808b3409ec2f
