舵机图表:为什么在values.yml中定义的环境变量没有添加到生成的清单中？

Question

我试图添加环境变量到我的wordpress头盔图表。我的values.yml文件看起来如下：

#pvc wordpress
persistence:
  enabled: false

#pvc mariadb
mariadb:
  enabled: false 

externalDatabase:
  host: mysql
  port: 3306
  user: benighil@benighil 
  password: "SomePassword"
  database: bitnami_wordpress

extraEnv:
  - name: "WORDPRESS_DATABASE_SSL_CA_FILE" # <== THIS ONE
    value: /tmp/ca-cert

## Additional volume mounts
## Example: Mount CA file
extraVolumeMounts:
  - name: ca-cert
    mountPath: /tmp

## Additional volumes
## Example: Add secret volume
extraVolumes:
 - name: ca-cert
   secret:
     secretName: ca-cert

但是，我使用以下cmd生成一个模板：

helm template wp azure-marketplace/wordpress -n app --create-namespace -f values.yml > template.yml

当我搜索文件中的单词：WORDPRESS_DATABASE_SSL_CA_FILE时，template.yml：

terminal: grep WORDPRESS_DATABASE_SSL_CA_FILE template.yml，什么都没回！

我想知道为什么？

提前谢谢你！

正确的参数是extraEnvVars而不是extraEnv

## @param extraEnvVars Array with extra environment variables to add to the WordPress container
## e.g:
## extraEnvVars:
##   - name: FOO
##     value: "bar"

所以这些值应该是

extraEnvVars:
  - name: "WORDPRESS_DATABASE_SSL_CA_FILE" # <== THIS ONE
    value: /tmp/ca-cert

helm template wp azure-marketplace/wordpress -f values.yaml | grep "WORDPRESS_DATABASE_SSL_CA_FILE"
