NGINX - How to export the entire server block for a given domain

Question

I need a tool or one-liner or whatever, which will export the entire server {...} block containing the given domain.

For examples:

### 1)
cat conf.d/domains.conf
server {

  include http.conf;
  server_name example.com;

  # [...]

}

server {

  include https.conf;
  server_name foo.com;

  # [...]

}

server {

  include https.conf;
  server_name example.com;

  # [...]

}

---

./script conf.d/domains.conf example.com

server {

  include http.conf;
  server_name example.com;

  # [...]

}

server {

  include https.conf;
  server_name example.com;

  # [...]

}

### 2)
cat conf.d/domains.conf

server {

  include ssl.conf;
  server_name example-foo.com;

  # [...]

}

server {

  include ssl.conf;
  server_name example-bar.com
              example.com
              fake.domain.com;

  location / {
    return 204 "OK";
  }

  # [...]

}

server {

  # include headers.conf;
  include ssl.conf;

  server_name example-baz.com example.com;

  # [...]

}

server {
  include ssl.conf;
  root /var/www/;

  server_name example-baz.com exampleee.com;

  # [...]

}

---

./script conf.d/domains.conf example.com

server {

  include ssl.conf;
  server_name example-bar.com
              example.com;

  # [...]

}

server {

  include ssl.conf;
  server_name example-bar.com
              example.com
              fake.domain.com;

  location / {
    return 204 "OK";
  }

  # [...]

}

server {

  # include headers.conf;
  include ssl.conf;

  server_name example-baz.com example.com;

  # [...]

}

My config has a lot of lines and is divided into many external files.

Do you know the tools that do this? Or any suggestions?

Thanks!

Answer 1

You can use awk for this by filtering two patterns between a delimiter, in your case a domain and a curly brace '$domain {'

E.g:

awk '/exampledomain  {/,/}/' exampledomains.conf

This command will take the first delimiter:

exampledomain {

and the second delimiter, the closing curly brace:

}

And print out the contents including the domain line from a file of your choosing, in this example: exampledomains.conf

Please take into account the the input has to be literal for this to work, including empty spaces.
