Description: e2j2
        ====
        
        What is e2j2?
        -------------
        
        e2j2 (environment to jinja2 variables) is a commandline tool which will
        render jinja2 templates to textfiles. all environment variables can be
        used in the jinja2 templates, within the environment variables you can
        use special tags which give you the option to insert json, json file
        paths, base64 hashes, consul kv keys.
        
        e2j2 is intended to be used within docker containers, you can simply add
        the j2 extention to a configuration file and then run e2j2 before you’re
        starting the actual executable.
        
        Example:
        --------
        
        lets assume we want to render the following server block in nginx, if we
        place the server configuration in a nginx include directory for example
        /etc/nginx/conf.d
        
        .. code:: bash
        
           server {
             server_name {{ NGINX.server_name }};
             listen 80;
             listen [::]:80;
             error_page 500 502 503 504 /50x.html;
        
             location / {
               index {{ NGINX.index_page }};
               root {{ NGINX.web_root }};
             }
        
             location ~ \.php$ {
               fastcgi_index index.php;
               fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
               fastcgi_pass unix:{{ NGINX.fpm_socket }};
               fastcgi_split_path_info ^(.+\.php)(/.+)$;
               include {{ NGINX.fcgi_params }};
               root {{ NGINX.web_root }};
               try_files $uri =404;
             }
           }
        
        if you then set the NGINX environment variable, running e2j2 will render
        the jinja2 template and place it in the same folder:
        
        .. code:: bash
        
           ~> export NGINX='json:
           {
           "server_name": "www.myweb.com",
           "index_page": "index.php",
           "web_root": "/usr/local/www/myweb",
           "fcgi_params": "/usr/local/etc/nginx/myweb-fcgi-params",
           "fpm_socket": "/var/run/php-fpm/myweb.socket"
           }'
           ~> e2j2
        
           In: .
               rendering: nginx_vhost_config.conf.j2=>done => writing: nginx_vhost_config.conf=>done
        
           ~> cat nginx_vhost_config.conf
           server {
             server_name www.myweb.com;
             listen 80;
             listen [::]:80;
             error_page 500 502 503 504 /50x.html;
        
             location / {
               index index.php;
               root /usr/local/www/myweb;
             }
        
             location ~ \.php$ {
               fastcgi_index index.php;
               fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
               fastcgi_pass unix:/var/run/php-fpm/myweb.socket;
               fastcgi_split_path_info ^(.+\.php)(/.+)$;
               include /usr/local/etc/nginx/myweb-fcgi-params;
               root /usr/local/www/roundcube;
               try_files $uri =404;
             }
           }
