Docker-kerberos

A docker image that creates the simplest Kerberos KDC and a docker image that is a kerberos client.

What you get

• A KDC for your desired realm.
• The kadmin/admin principal with every permission.
• The noPermissions principal with no permissions. Useful for testing applications that use kerberos principals.
• The function kadminCommand which performs kadmin commands using the kadmin/admin principal.

Running

Just run docker-compose up on the root directory of this repo.

How to customize (eg. change the REALM)

1. Change the file kerberos.env. This way the properties will be shared between the kdc and the kerberos client.
2. Define environment variables in docker-compose.yml. You will need to define them for each service that uses kerberos.

Sugested usage of this repo

This repository has designed to bootstrap the creation of a KDC for projects that need a Kerberos installation to perform tests.

For example: you have a project that uses kerberos principals and you need to test it against a working Kerberos installation. You will need to create in your project repository the necessary files to setup a Kerberos. To bootstrap that process you can simply copy this repository files to your project and them modify them so that you can test your application inside the kerberos-client container.
