Go 如何设置头盔安装的注释

我正在尝试安装图表，并希望应用注释，以便在datadog中正确标记部署

Datadog需要：ad.datadoghq.com/tags:“{env:staging}”

我已经试过下面的各种咒语，但我不断得到下面的错误

$ helm install efs-provisioner stable/efs-provisioner \
  --set efsProvisioner.efsFileSystemId=fs-a1b2c3d4 \ 
  --set efsProvisioner.awsRegion=us-east-1 \
  --set annotations."ad\.datadoghq\.com/tags"="{\'env\': \'staging\'}"

错误：

Error: YAML parse error on efs-provisioner/templates/storageclass.yaml: 
error unmarshaling JSON: while decoding JSON: 
json: cannot unmarshal array into Go struct field .metadata.annotations of type string

---

假设您希望输出如下所示：

$ helm template efs-provisioner stable/efs-provisioner <flags> \
  | grep -m 1 -C 4 datadog
    chart: efs-provisioner-0.10.0
    release: "efs-provisioner"
    heritage: "Helm"
  annotations:
    ad.datadoghq.com/tags: '{"env": "staging"}'

$ helm template efs-provisioner stable/efs-provisioner \
  --set efsProvisioner.efsFileSystemId=fs-a1b2c3d4 \
  --set efsProvisioner.awsRegion=us-east-1 \
  --set annotations."ad\.datadoghq\.com/tags"="\{\"env\": \"staging\"\}"
