Installation
The documentation has a chapter on installing Fietsboek: https://docs.fietsboek.org/administration/installation.html
Docker
Fietsboek comes with a Dockerfile in its repository, which can be used as
the base for a containerized Fietsboek installation.
More information about the provided example can be found in the documentation.
Note that Python's virtual environments work well for isolating the right package versions, so if you do not need advanced container features or the level of isolation that containers provide, you can also use virtual environments.
