Quick Example
apiVersion: kubernetes.openmcf.org/v1
kind: RedisKubernetes
metadata:
name: my-redis
labels:
openmcf.org/provisioner: pulumi
spec:
replicas: 3
resources:
limits:
memory: 2Gi
cpu: 1000m
# Simple kubectl-style workflow
openmcf validate redis.yaml
openmcf apply -f redis.yaml
# Or use provisioner-specific commands
openmcf pulumi up -f redis.yaml --stack myorg/project/dev
