如何在jinja2的if语句中为saltstack比较嵌套的支柱键值 [英] How to compared a nested pillar key value in an if statement in jinja2 for saltstack

问题描述

我正在用一些盐包裹在jinja2中的盐堆状态.

I am working on a saltstack state with some salt wrapped in jinja2.

当我尝试使用jinja2比较支柱中的值时，参数似乎没有任何结果.

When I attempt to compare a value from a pillar using jinja2 it appears argument evaluates to nothing.

如果我使用salt cli查询值，它将返回期望值.

If I query the value using salt cli, it returns the expected value.

我希望我在jinja2的if语句中错误地引用了该值.

I expect I am referencing the value incorrectly in the if statement with jinja2.

这里是了解和查看此问题的所有必需信息:

Here is all the needed info to understand and look at this problem:

Salt Master ID是salt-dev

Salt Master id is salt-dev

Salt Minion ID在同一实例上，并且是salt-dev

Salt Minion id is on same instance and is salt-dev

这是最重要的文件:

base:
  'salt-dev':
    - docker-daemon.docker-daemon

这是位于/srv/pillar/docker-daemon/docker-daemon.sls

docker-daemon:
  - action: start
  - runlevel: enabled

这是salt cli命令的输出，返回小仆salt-dev的支柱内容:

Here is the output of the salt cli command returning the content of the pillar for the minion salt-dev:

# salt 'salt-dev' pillar.items
salt-dev:
    ----------
    docker-daemon:
        |_
          ----------
          action:
              start
        |_
          ----------
          runlevel:
              enabled

这是我在if语句中使用的值的输出，其中该值在jinja2中不返回任何内容，但在此处使用cli返回了预期的结果:

Here is the output of the value I am using in the if statement where the value returns nothing with jinja2, but returns as expected here with cli:

# salt 'salt-dev' pillar.get docker-daemon:action
salt-dev:
    start

jinja2的错误行是:

The line of jinja2 that is incorrect is:

{% if salt['pillar.get']('docker-daemon:action') == 'start' %}

它看起来:salt['pillar.get']('docker-daemon:action')什么也不返回，但是从上面显示的cli确实返回了什么.

It appears: salt['pillar.get']('docker-daemon:action') returns nothing, but from cli as shown above it does return something.

如果我添加一个默认值，则在此arg返回任何内容的情况下也将使用该默认值.

Also if I add a default value, which is used in the event this arg returned nothing it also works.

添加默认值的示例是:

{% if salt['pillar.get']('docker-daemon:action', 'def_value') == 'start' %}

我已经在下面的上下文中显示了它:

I have shown it in context below:

这是状态文件，其中if语句存在相同的问题:

Here is the state file where the if statements are having the same issue:

{% if ( (grains['osfinger'] == 'Oracle Linux Server-6') and (grains['osarch'] == 'x86_64')) %}
sync_docker-init:
  file.managed:
    - name: /etc/init.d/docker
    - source: salt://docker-daemon/templates/docker-init
    - user: root
    - group: root
    - mode: 755

action_docker-init:
  {% if salt['pillar.get']('docker-daemon:action') == 'start' %}
  service.running:
  {% endif %}

  {% if salt['pillar.get']('docker-daemon:action') == 'stop' %}
  service.dead:
  {% endif %}

    - name: docker
    - require: 
      - pkg: install_docker-engine
    - watch: 
      - file: sync_docker-init

  {% if salt['pillar.get']('docker-daemon:runlevel') == 'enabled' %}
    -- enable: True
  {% endif %}

  {% if salt['pillar.get']('docker-daemon:runlevel') == 'disabled' %}
    -- enable: False
  {% endif %}

  {% else %}
  event.send:
    - tag: 'salt/custom/docker-init/failure'
    - data: "Management of docker init failed, OS not permitted."
{% endif %}

目前我对Salt和jinja2还是很陌生，所以这是101种东西，但是我会很感谢您的帮助，几个小时后我什么都没发现.

I am quite new at the moment to salt and jinja2, so this is 101 stuff, but I would appreciate some help, I have found nothing for some hours yet.

我试图回声一下，看来我只是空白行

I attempted to echo this out and it seemed I just get a blank line

推荐答案

我找到了解决方案.

支柱文件/srv/pillar/docker-daemon/docker-daemon.sls形成为列表而不是地图.

The pillar file /srv/pillar/docker-daemon/docker-daemon.sls was formed as a list instead of a map.

我将其更改为:

docker-daemon:
  action: restart
  runlevel: disabled
