Overview

The SVS component is based on SaToSa and add InACademia specific components from teh SVS git repository

An ansible script, based on https://github.com/surfnet-niels/simplesaml-idp, is used to handle the configuration inside the docker container.

The overall setup is part of the inacademia-dev repository: https://github.com/surfnet-niels/inacademia-dev/tree/master/ssp-idp

Please note the SVS by itself does not deliver https based traffic. This is offloaded to POUND which is configures as part of the op.inacademia.local

The Dockerfile is the basis for the docker to be build. The build_svs.sh and run_svs.sh scripts will build and run the docker image respectively. The run_svs.sh script will test if the image exists, and if not, try to build it before running it.

In the config directory 2 subdirectories exist:

• cdb contains the client database, the RPs that are allowed to connect to InAcademia and which scopes and claims they are allowed to query
• production contains a set of directiries and files that describe the InAcademia setup.
  • attributemaps configures how SaToSa maps various protocols from and to its internal state. This needs no changes for InAcademia.
  • certs contains the certificates needed for SAML and OIDC (but NOT for https). 
  • plugins contain the InAcademia frontend, backend and microservices needed by SaToSa for InAcademia.For more info on the syntax used, see the SaToSa documentation https://github.com/IdentityPython/SATOSA/tree/master/doc
  • backend.xml contains Frontend SAML metadata and gets autogenerated when InAcademia docker starts.
  • rsyslog directory contains the configuration for the rsyslog. For the production service we use a central server we use for all logfiles from InAcademia
  • entityids.json contains a list of all IdPs that are allowed to use the InAcademia service.
  • idp.xml contains the SAML metadata of the IdPs that connect to InAcademia. In production thi sis typically not used and a MDQ is used instead.
  • for historic reasons teh certificates neede by SatoSa for the SAML endpoint and the OIDC endpoint are named differently. This is resolved by the use of the symlinks inAcademia* and metadata* who all point to the certificates in the certs directory
  • info.log is the InAcademia logfile.

Typically neither of these files need changes for a deploy.Docker file

The docker file is completely self contained, so it will build the SVS based on the condig and by pulling relevant repositories if needed

Deploying & Starting SVS

Run build_svs.sh to build a new docker.

Image Added

Assuming your build went without errors you can now run the docker image trough run_svs.sh

Image Added

Success, you now have a working SVS component. By defaul tthe debug log is being shown in the console

You can quickly test if the SVS component is responding by pointing your browser to http://svs.inacademia.local (NOT https!)

This should give you a page stating "Couldn't find the page you asked for!", which is basically SaToSa telling you you did not make a valid SMAL or OIDC request.
