# cdk8s-redis-sts  ![Release](https://github.com/opencdk8s/cdk8s-redis-sts/workflows/Release/badge.svg?branch=development)

Create a Replicated Redis Statefulset on Kubernetes, powered by the [cdk8s project](https://cdk8s.io) 🚀

## Disclaimer

This construct is under heavy development, and breaking changes will be introduced very often. Please don't forget to version lock your code if you are using this construct.

## Overview

**cdk8s-redis-sts** is a [cdk8s](https://cdk8s.io) library.

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
from constructs import Construct
from cdk8s import App, Chart, ChartProps
from opencdk8s.cdk8s_redis_sts import MyRedis

class MyChart(Chart):
    def __init__(self, scope, id, *, namespace=None, labels=None):
        super().__init__(scope, id, namespace=namespace, labels=labels)
        MyRedis(self, "dev",
            image="redis",
            namespace="databases",
            volume_size="10Gi",
            replicas=2,
            create_storage_class=True,
            volume_provisioner="kubernetes.io/aws-ebs",
            storage_class_name="io1-slow",
            storage_class_params={
                "type": "io1",
                "fs_type": "ext4",
                "iops_per_gB": "10"
            }
        )

app = App()
MyChart(app, "dev")
app.synth()
```

Then the Kubernetes manifests created by `cdk8s synth` command will have Kubernetes resources such as `Statefulset`, `ConfigMap` and `Service` as follows.
