Support variables within consul-template (for vault)

[Yasin Amadmia]

Hi,

I was wondering if there was way to use variables within consul-templates for vault ?

ex: 

{{ with $my_secret := vault "secret/path/my_secret" }} {{ end }}

I want to use a variable (Shell) instead of path

In Shell: export path=location1

Template: {{ with $my_secret := vault "secret/${path}/my_secret" }} {{ end }}

Template should retrieve from consul path secret/location1/my_secret

Is it possible ?

Hi Yasin,

You should be able to use consul-template's env function for this - https://github.com/hashicorp/consul-template#env. You can use Go template's printf to compose the path from fixed parts and substituting the environment variable from env. Also, you probably don't want to call that environment variable "path" to avoid conflating with "PATH" :-)
