Apache w/mod-auth-cas docker image

A Red Hat 8 Universal Base Image running Apache with a few helpful extras:

1. mod_auth_cas, configurable at runtime by setting environment variables.
2. A RemoteIP configuration suitable for running behind NGINX, Traefik, etc.
3. Our branded auto-index pages.

Listens on 8080/tcp.

CAS Configuration

The CAS configuration works for localhost and auth.berkeley.edu out-of-the-box. You can override any of the options defined in files/etc/httpd/conf.d/auth_cas.conf by setting environment variables of the form CAS_OPTION_NAME.

Example 1: Using auth-test instead of auth.

CAS_DOMAIN=auth-test.berkeley.edu

Example 2: Setting a production return URL.

CAS_ROOT_PROXIED_AS=https://mysite.lib.berkeley.edu

The environment variables are named after the corresponding CAS configuration directives. See the mod-auth-cas documentation. The only exception is CAS_DOMAIN, which is a helper variable for setting all of the other CAS URLs to a specific domain.

Trusted Proxies

See files/etc/httpd/conf.d/trusted_proxies.conf for the list of trusted proxies. This must be updated if/when a new ingress point is added.

Branded Index Pages

This image bakes in custom branding and styling for Apache-generated index pages. See files/var/www/autoindex for details.
