SaltStack 谷物错误

Question

我的 Saltstack minions 有一个奇怪的问题。我在 Ubuntu 16.04 上安装了 minions，与 master 的连接工作正常。但是当我尝试在我的 minion 上创建一个 state.apply 我得到一个 Jinja 模板错误：

jenkins01-prod:
      Data failed to compile:
----------
Rendering SLS 'base:salt.minion' failed: Jinja error: coercing to Unicode: need string or buffer, int found
 /var/cache/salt/minion/files/base/salt/map.jinja(43):

 {##
 Setup variable using grains['os_family'] based logic, only add 
key:values here
that differ from whats in defaults.yaml
 ##}
  {% set osrelease = salt['grains.get']('osrelease') %}
 {% set os_family_map = salt['grains.filter_by']({    <======================

  'pkgrepo': 'deb http://repo.saltstack.com/apt/' +
  salt['grains.get']('os')|lower + '/' + salt['grains.get']('osmajorrelease', osrelease) + '/amd64/latest ' + salt['grains.get']('oscodename') + ' main',
  'key_url': 'https://repo.saltstack.com/apt/' + salt['grains.get']('os')|lower + '/' + salt['grains.get']('osmajorrelease', osrelease) + '/amd64/latest/SALTSTACK-GPG-KEY.pub',

{% set os_family_map = salt['grains.filter_by']({
TypeError: coercing to Unicode: need string or buffer, int found

我查看了小兵身上的谷物物品：

  os:
       Ubuntu
   os_family:
       Debian
   osarch:
       amd64
   oscodename:
       xenial
   osfinger:
       Ubuntu-16.04
   osfullname:
       Ubuntu
   osmajorrelease:
       16
   osrelease:
       16.04
   osrelease_info:
       - 16
       - 4

主机是 EC2 实例，在具有相同设置的另一台主机上工作正常。附件中有 salt --versions-report：盐版本：

Answer 1

在最近的 Salt 版本中 osmajorreleasegrain 从字符串转换为整数 (https://github.com/saltstack/salt/issues/35972)。你得到的错误是说你的 Jinja 模板需要字符串但得到整数而不是 ( TypeError: coercing to Unicode: need string or buffer, int found ).

我不确定状态内部到底做了什么，但解决这个问题的一种方法是在 .jinja 文件中将整数转换为字符串。例如像这样：

{% set osrelease = salt['grains.get']('osrelease')|string %}

希望对您有所帮助！
