## Requirements

Kubernetes: `>=1.21.0-0`

| Repository | Name | Version |
|------------|------|---------|
| https://clastix.github.io/charts | kamaji-etcd | >=0.8.1 |

[Kamaji](https://github.com/clastix/kamaji) requires a [multi-tenant `etcd`](https://github.com/clastix/kamaji-internal/blob/master/deploy/getting-started-with-kamaji.md#setup-internal-multi-tenant-etcd) cluster.
This Helm Chart starting from v0.1.1 provides the installation of an internal `etcd` in order to streamline the local test. If you'd like to use an externally managed etcd instance, you can specify the overrides and by setting the value `etcd.deploy=false`.

> For production use an externally managed `etcd` is highly recommended, the `etcd` addon offered by this Chart is not considered production-grade.

## Install Kamaji

To install the Chart with the release name `kamaji`:

        helm upgrade --install --namespace kamaji-system --create-namespace clastix/kamaji

Show the status:

        helm status kamaji -n kamaji-system

Upgrade the Chart

        helm upgrade kamaji -n kamaji-system clastix/kamaji

Uninstall the Chart

        helm uninstall kamaji -n kamaji-system

## Customize the installation

There are two methods for specifying overrides of values during Chart installation: `--values` and `--set`.

The `--values` option is the preferred method because it allows you to keep your overrides in a YAML file, rather than specifying them all on the command line. Create a copy of the YAML file `values.yaml` and add your overrides to it.

Specify your overrides file when you install the Chart:

        helm upgrade kamaji --install --namespace kamaji-system --create-namespace clastix/kamaji --values myvalues.yaml

The values in your overrides file `myvalues.yaml` will override their counterparts in the Chart's values.yaml file. Any values in `values.yaml` that weren’t overridden will keep their defaults.

If you only need to make minor customizations, you can specify them on the command line by using the `--set` option. For example:

        helm upgrade kamaji --install --namespace kamaji-system --create-namespace clastix/kamaji --set etcd.deploy=false

Here the values you can override:

## Values

| tolerations | list | `[]` | Kubernetes node taints that the Kamaji controller pods would tolerate |

## Installing and managing etcd as DataStore

Kamaji supports multiple data store, although `etcd` is the default one: thus, an initial cluster will be created upon the Chart installation.

The `DataStore` resource can be configured with the proper values in case of overrides when using a different driver, otherwise all the required data will be inherited by the Chart values.
