将YAML转换为JSON时出现错误:YAML:第24行:没有找到期望的键

Question

获取错误Postgres服务部署失败。用yamllint检查yaml，它是有效的，但仍然得到错误。部署文件包含ServiceAccount、Service和statfulset。

postgresdeployment.yaml

1. 是否有任何无效的yaml语法?
2. 是否缺少缩进?
3. 这里缺少哪个节点?

helm(和它的golang文本/模板对等体)中的模板必须是一个令牌，否则yaml认为{打开一个字典，然后{试图打开一个子字典，就像在JSON中一样，这不是一个有效的结构

所以你需要:

serviceAccountName: postgres
securityContext:
{{- toYaml .Values.securityContext | nindent 8 }}
