# ClickHouse Helm Chart

Fully functioning replicated ClickHouse environment. CLI, Graphite and Tabix UI included. By default there are 2 replicas.

It's also important to create replicated tables correctly, you may check sample schema in `sample-schema.sql`, which you have to execute on each node (`CREATE` queries are not replicated in ClickHouse).

## Run

```bash

helm install -f ./clickhouse/values.yaml --name ch --namespace=default ./clickhouse

```

## Client

Works if `client.enabled` is `true`.

Log into container:

```bash

kubectl exec -it $(kubectl get pod -l app=clickhouse-client -o jsonpath="{.items[0].metadata.name}") -- /bin/bash

```

Connect to CH node:

```bash

/usr/bin/clickhouse-client --host clickhouse-0.clickhouse

```

## Tabix UI

Works if `tabix.enabled` is `true`.

This chart includes [tabix.io](https://tabix.io/) as UI if you need it.
