apiVersion: v1
data:
  server-snippet: |
    if ($http_x_azure_fdid !~* "55ce4ed1-4b06-4bf1-b40e-4638452104da" ) {
        return 403;
    }
  use-forwarded-headers: "true"
kind: ConfigMap

在以下方法中设置值时，如何使用头盔实现上述配置?

How to achieve the above config using helm when setting the values in the following approach?

helm upgrade --install nginx-ingress-controller ingress-nginx/ingress-nginx \
    --namespace "${namespace}" \
    --version "${chart_version}" \
    --set controller.replicaCount="${replicas}" \
    --set-string controller.config.use-forwarded-headers=true \
    --set-string controller.config.server-snippet=<?> \
    --debug

推荐答案

您可以如下定义多行环境变量，

You can define a multiline environment variable as below,

read -d '' conf << EOF
if ($http_x_azure_fdid !~* "55ce4ed1-4b06-4bf1-b40e-4638452104da" ) {
       return 403;
}

EOF

一旦定义了环境变量，请在头盔-set-string controller.config.server-snippet = arg中引用它，如下所示，

Once the environment variable is defined, refer it in the helm --set-string controller.config.server-snippet= arg as below,

helm upgrade --install nginx-ingress-controller ingress-nginx/ingress-nginx \
    --namespace "${namespace}" \
    --version "${chart_version}" \
    --set controller.replicaCount="${replicas}" \
    --set-string controller.config.use-forwarded-headers=true \
    --set-string controller.config.server-snippet=$conf \
    --debug
