Question

我想使用Ubuntu 16.04在远程计算机上安装Docker，使用Ansible并遵循https://docs.docker.com/engine/installation/linux/ubuntu/的官方文档。一切似乎都有效，但是当ansible以名称＆＃34;安装Docker＆＃34;来完成任务时，我得到＆＃34;没有包匹配＆＃39; docker-ce＆＃39;可用＆＃34;。

以下是该剧本的一部分，从设置存储库的角度来看：

- name: set the stable repository
    apt_repository: 
      repo: deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable


  - name: Update all packages to the latest version
    apt:
      upgrade: dist

  - name: install Docker
    apt:
      name: docker-ce
      state: present

问题出在哪里？

Answer 1

问题是apt存储库添加错误。以下行实际上是添加$(lsb_release -cs)并且未插入：

repo: deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable

你想要的是使用Ansible事实而不是这样：

repo: deb [arch=amd64] https://download.docker.com/linux/ubuntu {{ ansible_lsb.codename }} stable

这应该会在/etc/apt/sources.list.d/download_docker_com_repo.list文件中显示以下内容：

deb [arch=amd64] https://download.docker.com/linux/ubuntu trusty stable

注意：您可能还需要apt_key导入GPG密钥（根据安装说明）。

Answer 2

你没有运行apt-get update，所以新的repo没有被阅读

Answer 3

如果Ansible版本＆gt; = 2.0：

，您可以使用通用OS包管理器模块

- name: install docker
  package:
    name: docker-ce
    state: present

Answer 4

我知道您正在搜索ubuntu安装，但是对于其他用户（如我之前搜索的），我将共享我的centos版本（正在运行）：

Answer 5

你需要运行

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable" sudo apt-get update sudo apt-get install docker-ce

Ansible：没有可用于docker-ce的软件包
