我正在使用Ansible playbook来管理Docker容器的安装 . 我有以下剧本,安装Cassandra:
我想在本地运行这个playbook,并将它安装到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设置制作了一个库存文件:
[local]
localhost ansible_ssh_port=2022 ansible_ssh_user=docker ansible_ssh_private_key_file=~/.ssh/id_boot2docker
但是当我运行playbook时,它失败并显示错误“ /bin/sh: /usr/bin/python: not found
”:
$ ansible-playbook db-setup.yml -i hosts.local

即使"gather facts"关闭,我仍然会收到错误 . 如果我SSH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
2 回答
boot2docker ssh "tce-load -w -i python.tcz"
也为这个技巧(你需要互联网;-))为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
还会添加到您的库存文件中:
解决方案很简单:Boot2Docker默认不安装Python .
要安装,请运行
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
