Question

我已按照以下步骤将Docker和Ansible安装到我的AWS Ec2 Linux：

sudo yum update -y
sudo yum install docker -v
sudo service docker start

sudo yum-config-manager --enable epel
sudo yum repolist
sudo yum install ansible

当我尝试使用ansible将docker图像拖到我的AWS Ec2 Linux上时，发现以下错误消息。

fatal: [127.0.0.1]: FAILED! => {"changed": false, "msg": "Failed to import docker or docker-py - No module named docker. Try `pip install docker` or `pip install docker-py` (Python 2.6)"}

Docker版本

Client:
 Version:           18.06.1-ce
 API version:       1.38
 Go version:        go1.10.3
 Git commit:        e68fc7a215d7133c34aa18e3b72b4a21fd0c6136
 Built:             Fri Oct 26 23:38:19 2018
 OS/Arch:           linux/amd64
 Experimental:      false

可用的版本是

ansible 2.6.8
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/ec2-user/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.6/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.6.9 (unknown, Nov  2 2017, 19:21:21) [GCC 4.8.5 20150623 (Red Hat 4.8.5-11)]

这是我的剧本档案的一部分

- name: Pull a container image
  docker_container:
    name: mynodejs
    image: registry.gitlab.com/ppshein/test:latest
    pull: yes
    state: started

请告诉我在AWS Ec2 Linux中缺少哪些配置。

Answer 1

您需要安装Python docker模块：

sudo yum install python-pip
sudo pip install docker

Answer 2

对 ansible 2.9.1 和 Ubuntu 20.10 有用的是安装 python3-docker：

sudo apt-get install python3-docker

Answer 3

将此ansible_python_interpreter添加到您的“主机”文件中：

将[servers:vars]更改为[your-group-of-server-names:vars]

对于Python> = 2.7

[servers:vars]
ansible_python_interpreter=/usr/bin/python3 # For Python3 [default Ubuntu-18.04]

Python <= 2.7

[servers:vars]
ansible_python_interpreter=/usr/bin/python # For Python2.7

Answer 4

对于路过的人，通过apt安装了ubuntu时遇到了同样的问题，在Ubuntu上给出了2.7.15。通过安装最新版本进行了修复：

sudo apt install software-properties-common
sudo apt-add-repository --yes --update ppa:ansible/ansible
sudo apt install ansible

到今天为止为2.9.2。

无法导入docker或docker-py-没有名为docker的模块
