python - SaltStack 颗粒错误

Question

我的 Saltstack 仆从有一个奇怪的问题。
我在 Ubuntu 16.04 上安装了 minions，并且与 master 的连接工作正常。
但是，一旦我尝试在我的奴才上设置 state.apply，我就会收到 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']({    <======================
'Debian':  {
  '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',

Traceback (most recent call last):

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

我检查了小兵身上的 Cereal 元素:

  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，在具有相同设置的其他主机上可以正常工作。

Answer 1

在最近的 Salt 版本中 osmajorrelease grain 已从字符串转换为整数 ( https://github.com/saltstack/salt/issues/35972 )。您得到的错误是说您的 Jinja 模板需要字符串，但取而代之的是整数 ( TypeError: coercing to Unicode: need string or buffer, int found )。

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

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

希望这可以帮助!
