Question

考虑到以下试验游戏手册:

---
- name: Node Tolerations
  hosts: localhost
  gather_facts: false
  vars:
    tolerations:
      - key: node.cilium.io/agent-not-ready
        operator: Exists
        effect: NoExecute
      - key: node-role.kubernetes.io/control-plane
        operator: Exists
        effect: NoSchedule
  tasks:
    - name: Set node tolerations fact
      ansible.builtin.set_fact:
        node_tolerations: "{{ (node_tolerations | default([]) | union([ : .join((item.key, item.effect))])) }}"
      with_items:  {{ tolerations }} 

    - name: Set node taint fact
      ansible.builtin.set_fact:
        node_taint: "{{ node_tolerations | select( search ,  control-plane ) }}"

    - name: Variable output
      ansible.builtin.debug:
        var: node_taint

产生预期结果:

ok: [localhost] =>
  node_taint:
  - node-role.kubernetes.io/control-plane:NoSchedule

使用<代码>node_taint a. 列入Jinja2模板的事实:

node-taint:
  {{ node_taint | indent(2) }}

产生以下错误:

AttributeError:  list  object has no attribute  splitlines

As temporary workaround, I used:

node-taint:
  - {{ node_taint | join }}

但是,我倾向于最初的金贾2格式,允许我界定适当的诱惑。我很想知道,你是否能够提供一些见解,什么是适当的解决办法。

Edit: 上文详细游戏手册的第二次使用是:

tolerations:
  {{ tolerations | indent(2) }}

产生同样的错误。我更希望避免在金贾模板中使用<条码>(<>>>>格式,并在事实上操纵数据,使我能够在模板内使用适当的<条码>indent。

自node_toleration 清单是一份清单,您可以自行编制每个项目的目录:

node-taint:
{% for toleration in node_toleration | select( search ,  control-plane ) %}
{{     * 2 }}- {{ toleration }}
{% endfor %}

或

node-taint:
{% for toleration in node_toleration | select( search ,  control-plane ) %}
{{  -   + toleration | indent(2) }}
{% endfor %}
