Transpile Kubernetes manifests with your simple values.yaml files using python type-hints. Gybe is a simple, declarative, and more pythonic alternative to helm that makes it easier to develop modest kubernetes deployments.
Python 3.10+
pip install gybe
Create a simple values.yaml file:
image: python:3
command:
- python
- -m
- http.serverCreate a chart.py file:
import gybe
def create_standard_container(image: str, command: List[str]):
return gybe.k8s.Container(image=image, command=command, name='my-python-server')
@gybe.transpiler
def two_pods(image: str, command: list[str]) -> gybe.Manifest:
pod_spec = gybe.k8s.PodSpec(
containers=[create_standard_container(image=image, command=command)],
)
return [
gybe.k8s.Pod(
kind='Pod',
apiVersion='v1',
metadata=gybe.k8s.ObjectMeta(name='pod-1'),
spec=pod_spec,
),
gybe.k8s.Pod(
kind='Pod',
apiVersion='v1',
metadata=gybe.k8s.ObjectMeta(name='pod-2'),
spec=pod_spec,
),
]
if __name__ == '__main__':
two_pods()Now run your transpiler with your values file:
python chart.py values.yamlapiVersion: v1
kind: Pod
metadata:
name: pod-1
spec:
containers:
- command:
- python
- -m
- http.server
image: python:3
name: my-python-server
---
apiVersion: v1
kind: Pod
metadata:
name: pod-2
spec:
containers:
- command:
- python
- -m
- http.server
image: python:3
name: my-python-serverIf you're feeling lucky, you can pipe that into kubectl:
python chart.py values.yaml | kubectl apply -f -pod/pod-1 created
pod/pod-2 created
kubectl get podsNAME READY STATUS RESTARTS AGE
pod-1 1/1 Running 0 5s
pod-2 1/1 Running 0 5s
python chart.py values.yaml | kubectl delete -f -pod "pod-1" deleted
pod "pod-2" deleted
