ood_portal.yml

Relying on the default build is fine for a demo deployment, but it is not recommended for a production environment. Options can be configured by default under the file /etc/ood/config/ood_portal.yml.

The RPMs copy this file from /opt/ood/ood-portal-generator/ood_portal_example.yml during the installation.

All the default options are listed in this configuration file. Feel free to read it through before continuing on.

Configure Reverse Proxy

The reverse proxy will proxy a request to any specified host and port through IP sockets. This is different than what is used for proxying to per-user NGINX processes through Unix domain sockets. This can be used to connect to Jupyter notebook servers, RStudio servers, VNC servers, and more… This is disabled by default as it can be security risk if not properly setup using a good host_regex.

A URL request to the node_uri will reverse proxy to the given host and port using the full URI path. So a request to the frontend Apache proxy that looks like:

GET /<node_uri>/<host>/<port>/... HTTP/1.1
Host: ondemand.example.edu

will be reverse proxied to the backend server with the following request format:

GET /<node_uri>/<host>/<port>/... HTTP/1.1
Host: <host>:<port>

A URL request to the rnode_uri will reverse proxy to the given host and port using the relative URI path. So a request to the frontend Apache proxy that looks like:

GET /<rnode_uri>/<host>/<port>/... HTTP/1.1
Host: ondemand.example.edu

will be reverse proxied to the backend server with the following request format:

GET /... HTTP/1.1
Host: <host>:<port>

Notice that we strip off the portion of the URI request path that is used to determine the backend web server.

Both formats are provided to better support the varying capabilities for the multitude of web application servers. For the case of using node_uri the developer will need to modify the web server to accommodate requests with a sub-URI that follows the dynamic formatting of /<node_uri>/<host>/<port>. For the case of using rnode_uri the developer needs to confirm that all assets and links supplied by the web server are relative and not absolute.

host_regex (String)

the regular expression used as a whitelist for allowing a user to reverse proxy to a given host

Default

Allow proxying to all hosts in the world (please change this if you enable this feature)

host_regex: "[^/]+"
Example

host_regex: "[\\w.-]+\\.example\\.com"
node_uri (String, null)

Configure per-user NGINX

The reverse proxy will proxy a request under the pun_uri URI to the user’s per-user NGINX (PUN) process through Unix domain sockets. It will send process signals to the user’s PUN through the nginx_uri URI. If either of these properties are null then PUN access will be disabled.

nginx_uri (String, null)

Default

User’s can send signals to PUN through http://www.example.com/nginx
