kubernetes-cluster-mock

kubernetes-cluster-mock is a mock to a Kubernetes Cluster API using Flask. You can use it to test your application that integrates with Kubernetes API.

kubernetes-cluster-mock is available on dockerhub. To run it, just execute:

containerId=$(docker run -d -p 9988:9988 ezequielmr94/kubernetes-cluster-mock:latest)
docker cp $containerId:/root/kubernetes-cluster-mock/assets/config ./local_config

Inside the assets folder you can find a kube config file to access the kubernetes-cluster-mock service. You can copy it from the container too.

For now, you can:

• List Nodes
• Create a ingress
• List ingresses
• Delete a ingress
• Create a ingress using kubectl create -f
• Create a pod
• List pods
• Delete a pod
• Create a pod using kubectl create -f
• Create a deploy
• Deploy creating pods
• List deploys
• Delete a deploy
• Create a deploy using kubectl create -f

Custom Routes

You can manually change the status of a pod using the route bellow:

POST - "/custom_routes/change_pod_phase/<namespace>/<pod_name>/<phase>"

Example:

import requests
requests.post("http://localhost:9988/custom_routes/change_pod_phase/production/pod-1/Pending")

---

You can manually change cluster size:

POST - "/custom_routes/change_cluster_size/<new_size>"

Example:

import requests
requests.post("http://localhost:9988/custom_routes/change_cluster_size/2")

How to build?

Using pyenv with pyenv-virtualenv

You also should use virtualenv to build/develop the project and I recommend the use of pyenv with pyenv-virtualenv to manage multiple python environments.

pyenv install 3.7.5
pyenv virtualenv 3.7.5 kubernetes-cluster-emulator

Installing dependencies (Python 3.7.5)

Open your bash and run the follow command to install all the project dependencies, you just need to run the command one time

python -m pip install --upgrade pip
python -m pip install -r requirements.txt
