Nenhum pacote correspondente 'docker-ce' está disponível com ansible

Question

No ubuntu 18.04 estou executando esta função ansible (versão 2.5.1):

---
- name: Add Docker apt repository key.
  apt_key:
    url: "https://download.docker.com/linux/ubuntu/gpg"
    state: present

- name: gather facts
  setup:    

- name: Set the stable docker repository
  apt_repository: 
    repo: "deb [arch=amd64] https://download.docker.com/linux/ubuntu {{ ansible_lsb.codename }} stable"
    state: present
    update_cache: yes    

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

Com este manual:

---


- hosts: localhost
  connection: local
  gather_facts: False
  become: true

  pre_tasks:
  - name: Install python for Ansible
    raw: test -e /usr/bin/python || (apt -y update && apt install -y python-minimal)

  tasks:  
  - name: Install list of packages
    apt: name={{item}} state=latest
    with_items:
         - nano
         - git
         - htop
         - gitg

  roles:
      - {role: 'docker', tags: 'docker'}

Mas recebo o seguinte erro:

PLAY [localhost] *******************************************************************************************************************************

TASK [Install python for Ansible] **************************************************************************************************************
changed: [localhost]

TASK [docker : Add Docker apt repository key.] *************************************************************************************************

PLAY RECAP *************************************************************************************************************************************
localhost                  : ok=4    changed=1    unreachable=0    failed=1   

Então, por algum motivo, o pacote docker-ce não pode ser encontrado, isso mudou recentemente ou é algo que estou fazendo de errado?

Além disso, quando eu olho: /etc/apt/sources.list ele não contém:

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

entrada.

    

Answer 1

Você precisa usar edge ao invés de stable com bionic (18.04), ele ficará estável no futuro.

- name: Set the stable docker repository
  apt_repository: 
    repo: "deb [arch=amd64] https://download.docker.com/linux/ubuntu {{ ansible_lsb.codename }} edge"
    state: present
    update_cache: yes    

    

Answer 2

Existe um post correspondente no StackOverflow: Ansible: nenhum pacote disponível para o docker-ce .

A resposta aceita diz:

Or you can use generic OS package manager module if Ansible version >= 2.0:

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

Um comentário abaixo diz:

replace $(lsb_release -cs) with xenial (for ubuntu 16.04) from your /etc/apt/sources.list and retry

Também é possível verificar o ansible-galaxy primeiro e usar um papel bem testado como o link . Não há necessidade de reinventar a roda.
