Docker Installation

Upon every release of the CAS software, docker images are tagged and pushed to the Apereo CAS repository on Docker Hub. Images can be pulled down via the following command:

1
docker pull apereo/cas:v[A.B.C]

…where [A.B.C] represents the image tag that is mapped to the CAS server version.

Overview

A dockerized CAS deployment is an existing CAS overlay project that is wrapped by Docker. The overlay project already includes an embedded container to handle the deployment of CAS. The overlay project also includes an embedded build tool so that builds and deployments of CAS would not require a separate step to download and configure choices.

The docker images that are hosted on Docker Hub are mostly meant to be used as quickstarts and demos. You may also be able to use them as base images to add your customizations into the image. The image is built out of an existing CAS WAR Overlay.

When you generate a CAS WAR Overlay project using the CAS Initializr., please refer to the instructions provided in the README.md file to review options for building CAS Docker images.
