Virtual hosts

Use vhosts to safely expose services (sites/webapps etc) through public domains.

Service mapping

Vhosts essentially serve two purposes, traffic routing and mapping to ID providers.

A single XP runtime instance may offer multiple services. By default, XP provides the following endpoints:

  • localhost:8080/webapp/<app-name>/ (webapp engine)

  • localhost:8080/site/<repo>/<branch>/<path> (site engine)

  • localhost:8080/admin/ (admin engine)

By using vhosts, traffic for specific domains and url patterns may be routed directly to defined service paths in XP.

I.e. example.com -> 8080/site/default/master/homepage

With vhosts enabled, unexposed services are no longer accessible.

Vhosts may also define the relationship to one or more ID providers. This enables pluggable authentication on a per vhost basis.

Vhosts only apply to XP service port (defaults to 8080), not the monitoring and management ports.

Examples

"Example Inc", yhe owner of "example.com" just finished building their new site. The published site is available on <host>:8080/site/default/master/homepage.

In this case, a vhost configuration looking like this will get the job done:

Sample vhost config file
enabled = true

mapping.example.host = example.com
mapping.example.source = /
mapping.example.target = /site/default/master/homepage

After saving the vhost config file, you should see the following line the XP log:

2019-05-10 11:34:17,234 INFO  c.e.x.w.v.i.c.VirtualHostConfigImpl - Virtual host is enabled and mappings updated.
Each mapping must have a unique mapping identifier, in this case we used example.

Also, "Example Inc" wants the admin console deployed on example.com/admin. To solve this, we will simply add another mapping to the config:

mapping.adm.host = example.com
mapping.adm.source = /admin
mapping.adm.target = /admin
mapping.adm.idProvider.system = default

This time we also added an ID provider to the mapping. This effectively activates system the default (and only) ID provider for this vhost.

Testing vhosts

To verify that your vhost config is working without setting up proxies or modifying your DNS: Simply add the following line to your hosts file.

<host-ip-address>     example.com
Location of hosts file on Mac/Linux_: /etc/hosts, on Windows: c:\Windows\System32\Drivers\etc\hosts

Pointing your browser to http://example.com:8080 will reveal the glorious result.
