用Ansible呈现错误的缩进Jinja模板

Question

我的YAML模板有缩进问题。

我不明白为什么limits没有达到正确的缩进水平。

有人知道吗？

spec:
  template:
    spec:
      containers:
        - name: argocd-notifications-controller
          resources:
            requests:
              cpu: {% if argocd_total_applications > argocd.totalApplications.level4 -%} "{{ argocd.notificationController.cpu.requests.level4 }}"
              {% elif argocd_total_applications > argocd.totalApplications.level3 and argocd_total_applications <= argocd.totalApplications.level4 -%} "{{ argocd.notificationController.cpu.requests.level3 }}" 
              {% elif argocd_total_applications > argocd.totalApplications.level2 and argocd_total_applications <= argocd.totalApplications.level3 -%} "{{ argocd.notificationController.cpu.requests.level2 }}" 
              {% elif argocd_total_applications <= argocd.totalApplications.level1 -%} "{{ argocd.notificationController.cpu.requests.level1 }}" {% endif -%}
              memory: {% if argocd_total_applications > argocd.totalApplications.level4 -%} "{{ argocd.notificationController.memory.requests.level4 }}"
              {% elif argocd_total_applications > argocd.totalApplications.level3 and argocd_total_applications <= argocd.totalApplications.level4 -%} "{{ argocd.notificationController.memory.requests.level3 }}"
              {% elif argocd_total_applications > argocd.totalApplications.level2 and argocd_total_applications <= argocd.totalApplications.level3 -%} "{{ argocd.notificationController.memory.requests.level2 }}"
              {% elif argocd_total_applications <= argocd.totalApplications.level1 -%}"{{ argocd.notificationController.memory.requests.level1 }}"{% endif -%}
            limits:
              memory: {% if argocd_total_applications > argocd.totalApplications.level4 -%} "{{ argocd.notificationController.memory.limits.level4 }}" 
              {% elif argocd_total_applications > argocd.totalApplications.level3 and argocd_total_applications <= argocd.totalApplications.level4 -%} "{{ argocd.notificationController.memory.limits.level3 }}" 
              {% elif argocd_total_applications > argocd.totalApplications.level2 and argocd_total_applications <= argocd.totalApplications.level3 -%} "{{ argocd.notificationController.memory.limits.level2 }}" 
              {% elif argocd_total_applications <= argocd.totalApplications.level1 -%} "{{ argocd.notificationController.memory.limits.level1 }}" 
              {% endif -%}

结果：

spec:
  template:
    spec:
      containers:
        - name: argocd-notifications-controller
          resources:
            requests:
              cpu: "150m"
              memory: "500Mi"
              limits:  ################# PROBLEM HERE WRONG LOCATION
              memory: "750Mi" 

Answer 1

下面是您的问题的一个最小的可重复的例子：

resources:
  requests:
    cpu: {% if true -%} "150m" 
    {% elif true -%} "" {% endif -%}
    memory: {% if true -%} "500Mi" 
    {% elif true -%} "" {% endif -%}
  limits:
    memory: {% if true -%} "750Mi" 
    {% elif true -%} "" {% endif -%}

实际上，它使下列情况成为：

resources: 
  requests: 
    cpu: "150m"  
    memory: "500Mi"  
    limits: 
    memory: "750Mi"  

这些不正确的缩进发生的原因是，在使用白空间控制删除所有endif的空格之后。

删除空白控件--或者更好地修复它们，以便它们删除正确的空白--您将生成预期的YAML：

resources:
  requests:
    cpu: {% if true -%} "150m" 
    {%- elif true -%} "" {%- endif %}
    memory: {% if true -%} "500Mi" 
    {%- elif true -%} "" {%- endif %}
  limits:
    memory: {% if true -%} "750Mi" 
    {%- elif true -%} "" {%- endif %}

将呈现为

resources: 
  requests: 
    cpu: "150m" 
    memory: "500Mi" 
  limits: 
    memory: "750Mi"
