Question

我正在尝试使用Ansible中的 jenkins_job 模块，它不断抛出错误Unable to create job, Unicode strings with encoding declaration are not supported. Please use bytes input or XML fragments without declaration.

我使用以下任务触发此错误，该任务位于main.yml调用的文件tasks / add_job.yml中：

- name: Install CloudBees Folder for {{ item }}
  jenkins_job:
    config: "{{ lookup('template', 'config.xml.j2') }}"
    name: {{ item }}
    password: "{{ jenkins_admin_password }}"
    url: "http://{{ jenkins_hostname }}:{{ jenkins_http_port }}"
    user: "{{ jenkins_admin_username }}"

任务/ add_jobs.yml多次调用此任务，如下所示：

- name: Include job array via vars.
  include_vars:
    file: jobs.yml

- name: Install jobs.
  include: add_job.yml
  with_items: "{{ jenkins_jobs }}"

var文件如下所示：

jenkins_jobs:
  - Job1
  - Job2

我的配置文件位于模板目录中，看起来像这样（我尝试了很多不同的XML文件，最后尝试使用来自ansible GitHub项目的this config：

<?xml version='1.0' encoding='UTF-8'?>
<project>
  <actions/>
  <description></description>
  <keepDependencies>false</keepDependencies>
  <properties>
    <jenkins.model.BuildDiscarderProperty>
      <strategy class="hudson.tasks.LogRotator">
        <daysToKeep>1</daysToKeep>
        <numToKeep>20</numToKeep>
        <artifactDaysToKeep>-1</artifactDaysToKeep>
        <artifactNumToKeep>-1</artifactNumToKeep>
      </strategy>
    </jenkins.model.BuildDiscarderProperty>
    <org.jenkinsci.plugins.gitbucket.GitBucketProjectProperty plugin="gitbucket@0.8">
      <linkEnabled>false</linkEnabled>
    </org.jenkinsci.plugins.gitbucket.GitBucketProjectProperty>
  </properties>
  <scm class="hudson.scm.NullSCM"/>
  <canRoam>true</canRoam>
  <disabled>false</disabled>
  <blockBuildWhenDownstreamBuilding>false</blockBuildWhenDownstreamBuilding>
  <blockBuildWhenUpstreamBuilding>false</blockBuildWhenUpstreamBuilding>
  <triggers/>
  <concurrentBuild>false</concurrentBuild>
  <builders/>
  <publishers/>
  <buildWrappers/>
</project>

我针对通过以下方式配置的本地Vagrant运行此目标：

Vagrant.configure(2) do |config|
  config.vm.box = 'ubuntu/xenial64'
  config.vm.network(:private_network, ip: '192.168.99.101')
  config.vm.network(:forwarded_port, guest: 8080, host: 8080)
  config.vm.provider :virtualbox do |provider|
    provider.customize ['modifyvm', :id, '--name', 'ansible-jenkins']
    provider.customize ['modifyvm', :id, '--cpus', '2']
    provider.customize ['modifyvm', :id, '--memory', '2048']
    provider.customize ['modifyvm', :id, '--nictype1', 'virtio']
  end
end

在收到此错误之前，我有很多问题，甚至让jenkins_job运行，因为它一直抱怨缺少依赖项，所以这是我在Ubuntu 16.04.2 LTS上的软件包安装列表

jenkins_job_dependencies:
  - build-essential
  - python-pip
  - python3-pip
  - libffi-dev
  - libssl-dev
  - libxml2-dev
  - libxslt1-dev
  - python-dev
  - python3-dev
  - python-lxml
  - python3-lxml
  - python-jenkins
  - python3-jenkins
  - python3-venv
  - git

这是-vvvv输出

我尝试了许多xml声明的排列：包括它，删除它，使用utf-16等，似乎没有任何工作。任何指针都会感激不尽。我很欣赏有很多其他方法可以通过Ansible（cUrl，cli等）创建作业，我正在移植我的项目以使用job-dsl插件，但如果我能使用'out'来完成这项工作，它会非常简洁开箱即用的'Ansible模块

好吧......所以这是我在StackOverflow上的第一个问题...如果我有什么不对，请道歉。

Answer 1

事实证明，我的主机广告资源中的ansible_python_interpreter设置为/usr/bin/python3。当我将其设置为/usr/bin/python时，问题就消失了。耶....

......除了这只是故事的一半。当我销毁并重新创建我的VM时，它在第一步失败，因为Ubuntu 16.04LTS没有/usr/bin/python它只有/usr/bin/python3。

我不想创建符号链接或做virtenv东西...所以我只是在之后将ansible_python_interpreter设置为/usr/bin/python 我安装了python2-dev apt包但是之前我运行了jenkins_script模块。然后我在运行脚本后再将其重新设置。

# Truncated playbook for brevity... - name: Install dependency package: "name=python-dev state=present" - name: Set the python interpreter to the symlink (which points at version 2.7) set_fact: ansible_python_interpreter: '/usr/bin/python' - name: Do script thing. jenkins_script: script: "{{ script_var }}" user: "{{ jenkins_username }}" password: "{{ jenkins_password }}" changed_when: true no_log: True - name: Set the python interpreter back to version 3 set_fact: ansible_python_interpreter: '/usr/bin/python3'

如果我能找到jenkins_script模块源代码的位置，我会做一个拉取请求来修复底层问题但是我无法弄清楚它在哪里......
