Docker container configuration for SimpleSAMLphp built on top of Alpine Linux

Includes build routines for both vanilla SimpleSAMLphp and a container preconfigured with the Tozny IDP module.

This project builds two Docker images, one each for:

• a vanilla SimpleSAMLphp server
• a Tozny Authentication-enabled SimpleSAMLphp server

To build either project, cd into the appropriate directory and run docker build .. Both containers are otherwise available on Docker Hub.

There are two example Docker Compose projects available to illustrate how the new containers can be used with Nginx as a front-end proxy. To run either project, cd into the appropriate directory, configure your parameters, and run docker-compose up.

Create a configuration file called /params.yml that defines your authentication sources and metadata (feel free to use params.yml.dist as an example):

# params.yml
entity_id:     This is a secret
secretsalt:    This is a secret
adminpassword: This is a secret
authsources:
  - name: This is a secret
    idp:  This is a secret
metadata:
  - entityid:       This is a secret
    metadata_set:   This is a secret
    ssos:
      binding:      This is a secret
      location:     This is a secret
    slo:
      binding:      This is a secret
      location:     This is a secret
    certdata:       This is a secret
    name_id_format: This is a secret

This file needs to be mounted into the container, either directly via:

$ docker run -v $(pwd)/myparams.yml:/params.yml tozny/simplesamlphp

or as a volume in docker-compose.yml. Either way, upon first run the container will automatically write SimpleSAMLphp's configuration files for you based on this document.

The two stacks will run on localhost, the vanilla server will be exposed on port 8080 and the one with Tozny integrated on port 8090.
