无效的 Kubernetes YAML 规范。此处不允许映射值

Question

我正在尝试部署我的 Kubernetes 应用，但它不断抛出错误：

Exception while processing templates/deployment.yaml
ERROR   2021-06-17 14:57:05    Invalid Kubernetes YAML Spec. mapping values are not allowed here
ERROR   2021-06-17 14:57:05     in 'string', line 27, column 24:
ERROR   2021-06-17 14:57:05                      valueFrom:

从这个错误中，我至少可以将其缩小到我的 deployment.yaml 文件。对于“valueFrom”错误，我可以将其跟踪到“env：”部分。从那里我认为这是一个格式问题。

部署.yaml

        {{- end}}
        {{- end}}

我不熟悉使用 Kubernetes 和 YAML。我认为这是一个格式问题，但是无论我在哪里看，格式看起来都是正确的。

看起来这是一个缩进问题：

- name: FILE_SYSTEM_ID
    valueFrom:
      configMapKeyRef:

应该是

- name: FILE_SYSTEM_ID
  valueFrom:
    configMapKeyRef:
