Manages Labs in your Kubernetes Cluster
Project description
Lab Orchestrator Lib
This package contains the lab orchestrator library.
Installation
pip3 install lab-orchestrator-lib
Documentation
Check out the developer documentation at laborchestratorlib.readthedocs.io.
Adapter
To use this library you need adapter classes. Adapter classes are used to connect the lab orchestrator lib to your database. How to write them is described in the adapter documentation
Adapter Libraries:
There is already one library that contains all adapters to use the lab orchestrator lib with django: LabOrchestratorLib-DjangoAdapter. This library also contains an example Django API.
The LabOrchestratorLib-FlaskSQLAlchemyAdapter project is not maintained and not working, but if you need an adapter for Flask-SQLAlchemy you can base them on this project.
Resources
The library contains two types of resources. The first is Kubernetes resources. This type contains NetworkPolicy
, VirtualMachineInstance
and Namespace
objects. These are resources from Kubernetes that doesn't need to be saved.
The second type is database resources. They are saved in the database. For every database resource an adapter needs to be added. This type contains user
, DockerImage
, Lab
and LabInstance
objects.
A DockerImage
is a link to a docker image that contains the VM image. A Lab
contains one or multiple (currently not supported) VMs, each one is linked to a DockerImage
. A lab can be started which results into a LabInstance
. A LabInstance
contains some VirtualMachineInstance
s running in a Namespace
that can be accessed with VNC. The LabInstances
are separated from other LabInstances
with NetworkPolicy
s.
Controller
This library makes use of something called controllers. A controller is a class that controls one resource. The controllers can (and should) be used to create, get and update resources.
A controller collection is a collection of all controllers. You can create one with the lab_orchestrator_lib.controllers.controller_collection.create_controller_collection(...)
function. This function takes all adapters, one api registry and a secret key for creating JWT tokens as parameter. The api registry is needed for the Kubernetes controllers and the adapters are injected into the database controllers.
Usage
To use this library create a APIRegistry and a controller collection. Than you can use the controllers in the controller collection to create new DockerImage
s, Lab
s and LabInstance
s.
For detailed information take a look at the developer documentation at laborchestratorlib.readthedocs.io.
Examples
An example of the implementation of the adapters and an example of how to used the controllers can be found in the LabOrchestratorLib-DjangoAdapter.
