linux - 无法导入 docker 或 docker-py - 没有名为 docker 的模块

Question

我已经安装了Docker和 Ansible到我的 AWS Ec2 Linux 如下:

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

当我尝试拉动 docker 时，我发现了以下错误消息使用 ansible 将图像上传到我的 AWS Ec2 Linux。

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

 OS/Arch:           linux/amd64

Ansible 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 ansible playbook 文件的一部分

- name: Pull a container image
  docker_container:
    name: mynodejs
    image: registry.gitlab.com/ppshein/test:latest
    pull: yes
    state: started
    published_ports:
      - 8080:80

请让我知道我错过了在 AWS Ec2 Linux 中配置的内容。

对我有用的 ansible 2.9.1 和 Ubuntu 20.10 是安装 python3-docker:

sudo apt-get install python3-docker
