# [DEPRECATED]



**This project is deprecated and replaced by [k8ssandra-operator](https://github.com/k8ssandra/k8ssandra-operator)**



Read [this blog post](https://k8ssandra.io/blog/other/comparing-for-clarity-k8ssandra-v1-x-and-the-k8ssandra-operator/) to see what differences exist between K8ssandra and k8ssandra-operator, and why we decided to build an operator.  

Follow our [migration guide](https://k8ssandra.io/blog/tutorials/how-to/how-to-migrate-an-existing-cluster-to-k8ssandra-operator-without-any-downtime/) to migrate from K8ssandra (and Apache Cassandra®) to k8ssandra-operator.



# K8ssandra

[K8ssandra](https://k8ssandra.io/) is a simple to manage, production-ready,

distribution of [Apache Cassandra](https://cassandra.apache.org/) and

[Stargate](https://stargate.io/) that is ready for 

[Kubernetes](https://kubernetes.io/). It is built on a foundation of rock-solid 

open-source projects covering both the transactional and operational aspects of

Cassandra deployments. This project is distributed as a collection of

[Helm](https://helm.sh/) charts. Feel free to fork the repo and contribute. If

you're looking to install K8ssandra head over to the [Quickstarts](https://docs.k8ssandra.io/quickstarts/).



## Components

K8ssandra is composed of a number of sub-charts each representing a component in

the K8ssandra stack. The default installation is focused on developer

deployments with all of the features enabled and configured for running with a

minimal set of resources. Many of these components may be deployed

independently in a centralized fashion. Below is a list of the components in the

K8ssandra stack with links to the appropriate projects.



### Apache Cassandra

K8ssandra packages and deploys [Apache Cassandra](https://cassandra.apache.org/)

via the [cass-operator](https://github.com/k8ssandra/cass-operator) project. Each

Cassandra container has the [Management API for Apache Cassandra

(MAAC)](https://github.com/datastax/management-api-for-apache-cassandra) and

[Metrics Collector for Apache

Cassandra(MCAC)](https://github.com/datastax/metric-collector-for-apache-cassandra)

pre-installed and configured to come up automatically.



### Stargate

[Stargate](https://stargate.io/) provides a collection of horizontally scalable

API endpoints for interacting with Cassandra databases. Developers may leverage

REST and GraphQL alongside the traditional CQL interfaces. With Stargate

operations teams gain the ability to independently scale coordination (Stargate)

and data (Cassandra) layers. In some use-cases, this has resulted in a lower TCO and

smaller infrastructure footprint.



### Monitoring

Monitoring includes the collection, storage, and visualization of

metrics. Along with the previously mentioned MCAC, K8ssandra utilizes

[Prometheus](https://prometheus.io/) and [Grafana](https://grafana.com/) for the

storage and visualization of metrics. Installation and management of these

pieces is handled by the [Kube Prometheus

Stack](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack)

Helm chart.



### Repairs

The Last Pickle [Reaper](http://cassandra-reaper.io/) is used to schedule and

manage repairs in Cassandra. It provides a web interface to visualize repair

progress and manage activity.



### Backup & Restore



Another project from The Last Pickle,

[Medusa](https://github.com/thelastpickle/cassandra-medusa), manages the backup

and restore of K8ssandra clusters. 



## Next Steps



If you are looking to run K8ssandra in your [Kubernetes](https://kubernetes.io/) 

environment check out the [Getting Started guide](https://k8ssandra.io/get-started/), with follow-up details for 

[developers](https://docs.k8ssandra.io/quickstarts/developer/) and 

[site reliability engineers](https://docs.k8ssandra.io/quickstarts/site-reliability-engineer/). 



We are always looking for contributions to the docs, helm charts, and underlying

components. Check out the [code contribution guide](https://k8ssandra.io/community/code-contribution-guidelines/) 

and [docs contribution guide](httpshttps://docs.k8ssandra.io/contribute/)



If you are a **developer** interested in working with the K8ssandra code, here is a 

[guide](https://github.com/k8ssandra/k8ssandra/blob/main/dev-quick-start.md) that will give you an introduction to:



* Important technologies and learning resources

* Project components

* Project processes and resources

* Getting up and running with a basic IDE environment

* Deploying to a local docker-based cluster environment (kind)

* Understanding the K8ssandra project structure

* Running unit tests

* Troubleshooting tips
