Reload endpoint

Added the endpoint /reload that reloads the proxy configuration.

EXTRA_FRONTEND

Added the EXTRA_FRONTEND environment variable. Its value will be added to the default frontend configuration. See the Environment Variables section for more info.

Custom error messages

Added the ability to create custom error messages by overwriting the default files. See the Custom Errors section of the documentation for more info.

HTTPS forwarding

Added HTTPS (443) mapping as a separate parameter httpsPort. It is the internal HTTPS port of a service that should be reconfigured. The port is used only in the swarm mode. If not specified, the port parameter will be used instead.

Wildcard domains

Domains can be prefixed with a wildcard.

...
  --label "com.df.serviceDomain=*domain.com" \
...

The above example would match any domain ending with domain.com (e.g. my-domain.com, my-other-domain.com, etc).

Templates, Outbound Host, Certificate Request

Templates

Added templateFePath and templateBePathreconfigure parameters. They allow custom Swarm templates.

Outbound host

Added outboundHostname reconfigure parameter. It represents the hostname where the service is running, for instance on a separate swarm. If specified, the proxy will dispatch requests to that domain.

The outbound hostname feature is useful when the proxy is not part of the swarm. In a large corporate network setting, swarms may be regularly decommissioned and re-created, but external parts integrating with the swarms can not be reconfigured.

Certificate Request

Certificates can now be added through the serviceCert reconfigure parameter. It contains content of the PEM-encoded certificate to be used by the proxy when serving traffic over SSL.

Rewriting Paths

See Rewriting Paths section of the documentation for more info.

Multi-domain support

Support for multiple domains has been added. Values of the serviceDomain parameter can be separated with comma (,).

Basic authentication

Basic authentication was added. It can be applied to all services through the proxy environment variable USERS or on the service level through the reconfigure parameter users.

Examples can be found in the Basic Authentication section of the Swarm Mode (Docker 1.12+) With Automatic Configuration documentation.

Stats user/pass environment variables

The following environment variables were added:

• STATS_USER
• STATS_PASS

They can be used to change the default username and password for the statistics page.

Please consult the Container Config section for more info.
