Ansible-container 使用 java8 创建 Docker 镜像 [英] Ansible-container create Docker image with java8

问题描述

我正在尝试使用 ansible-container build 命令创建简单的 Docker 映像.

I'm trying to create simple Docker image with ansible-container build command.

而且我无法找到解决我在这样做时遇到的错误的方法.

And I can't figure out a solution to the error I came across while doing so.

以下是最重要的文件:

main.yml

---
- hosts: scala-akka
  roles:
    - java8

container.yml

version: "1"
services:
  scala-akka:
    image: ubuntu:14.04

registries: {}

roles/java8/tasks/main.yml

---
# Add oracle ppa to apt_key
- name: Add oracke ppa to apt_repository
  apt_repository:
    repo: 'ppa:webupd8team/java'

# Install Oracle Java8
- name: Install oracle Java8
  apt:
    name: oracle-java8-installer
    state: present

每次尝试运行时都会遇到的错误

The error I'm coming across every time I try to run

ansible-container --debug build

ansible-container --debug build

看起来像是某种python问题，我仍然不知道如何解决这个问题.

It looks like some kind of python problem, still I have no clue how to fix this.

有什么建议吗?谢谢！

推荐答案

大多数 Ansible 模块都需要目标主机上的 Python(在您的情况下为容器).
ubuntu:14.04 Docker 镜像没有预装.

Most of Ansible modules require Python on target host (container in your case).
ubuntu:14.04 Docker image doesn't have one preinstalled.

在您的 main.yml 中使用它:

Use this in your main.yml:

---
- hosts: scala-akka
  gather_facts: false

  pre_tasks:
    - raw: 'which python || (apt-get -q -y update && apt-get install -q -y python-minimal)'
    - setup:

  roles:
    - java8
