jsonQuery usage question #65

Open nemd opened 7 years ago

nemd commented 7 years ago

I'm not quite sure how to use it :/

I'm trying to build docker for nginx proxy and I could use json to define upstreams but I don't know how to build env file. At the moment I use simple --env-file for docker run but its construction doesn't allow for json - please share some light for it.

Also It would be nice to extend your - extremaly useful - script to use loops for templates.

I was looking for a similar solution so the question should read "How to read json content from file instead of .Env"

I can't see that it's possible in docker{-compose} to ask for file contents as an Env value.

I also can't see how to ask GoLang templates to use a file as content instead of just referencing and Env key

In my use case, I want to take the acme.json file from traefik and parse it with jsonQuery to extract certs and keys for delivering to another service (pgbouncer) TLS config.
