Vault injector template

Hi, all,

I am looking for a way to dump all the key and values in a particular tree. Is that possible?

    vault.hashicorp.com/role: "app_role"
    vault.hashicorp.com/agent-inject-secret-id: "app/ie"
    vault.hashicorp.com/agent-inject-template-secret-vars: |
      {{ with secret “app/ie” }}
        {{ range $k, $v := .Data }}
          {{ $k }}: {{ $v }}
        {{ end }}
      {{ end }}  

What I get is serialized data… of the first key…

data: map[id:ie]
metadata: map[created_time:2020-11-11T20:04:10.551043994Z deletion_time: destroyed:false version:1]

in vault i have structure of …

app/ie
id=ie
app/ie/parms
prams1:1
parms2:2
app/ie/ssl
ssl.crt:“cert”
sslkey:“key”

I wanted to have all keys and values in one file env, which contain all keys in the tree… Is that possible?
