Could you help provide an example on map function?

[Richard Yang]

Hi, folks, I am trying to populate a map like property collection like below (it could be any number of entries in the map):

'https://server1.com', { 'property1': 'value11', 'property2': 'value21' },
'https://server2.com', { 'property1': 'value12', 'property2': 'value22' },
'https://server3.com', { 'property1': 'value13', 'property2': 'value23' },
   .......
As you can see, it is more like a map with the keys being a unique url.
I wonder if I can use template map function. The confD website has this documentation:
Template Functions
kelseyhightower/confd/blob/master/docs/templates.md
However, I am not very clear how to do it. Could you give me a concrete example?
Thanks.

Hi,

It's been a while since I've last worked with confd, but here's some code that might help solve your issue.

nginx.conf.tmpl

upstream app {

   {{range gets "/app/powerping/abd23/es/conf/*"}}

  {{$data := json .Value}}

server {{$data.Conf.NetworkSettings.IPAddress}}:9200;

  {{end}}

  keepalive 1024;

}

server {

  server_name _;

  location / {

    proxy_pass http://app;

    proxy_redirect off;

    proxy_set_header Host $host;

    proxy_set_header X-Real-IP $remote_addr;

    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    default_type text/html;

    error_page 404 = /fallback;

  }

}

Cheers,

Rustin

Thanks, Rustin, for your help. I think I figured it out now. I had to learn some golang templating.
