# G2
|
||||
[G2 by AppsCode](https://github.com/appscode/g2) is a modern implementation of Gearman server in GO.
|
||||
## TL;DR;
|
||||
|
||||
```bash
|
||||
$ helm install stable/g2
|
||||
```
|
||||
|
||||
## Introduction
|
||||
|
||||
This chart bootstraps a [Gearman server](https://github.com/appscode/g2) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
|
||||
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes 1.3+
|
||||
|
||||
## Installing the Chart
|
||||
To install the chart with the release name `my-release`:
|
||||
```bash
|
||||
$ helm install --name my-release stable/g2
|
||||
```
|
||||
The command deploys G2 Gearman server on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
|
||||
|
||||
> **Tip**: List all releases using `helm list`
|
||||
|
||||
## Uninstalling the Chart
|
||||
|
||||
To uninstall/delete the `my-release`:
|
||||
|
||||
```bash
|
||||
$ helm delete my-release
|
||||
```
|
||||
|
||||
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
||||
|
||||
## Configuration
|
||||
|
||||
The following tables lists the configurable parameters of the Stash chart and their default values.
|
||||
|
||||
|
||||
| Parameter | Description | Default |
|
||||
| ------------------------ | ----------------------------------------------------------------- | ------------------- |
|
||||
| `replicaCount` | Number of stash operator replicas to create | `1` |
|
||||
| `g2.image` | G2 container image | `appscode/gearmand` |
|
||||
| `g2.tag` | G2 container image tag | `0.5.0` |
|
||||
| `g2.pullPolicy` | G2 container image pull policy | `IfNotPresent` |
|
||||
| `g2.serviceType` | G2 service type | `ClusterIP` |
|
||||
| `rbac.install` | install required rbac service account, roles and rolebindings | `false` |
|
||||
| `rbac.apiVersion` | rbac api version `v1alpha1|v1beta1` | `v1beta1` |
|
||||
|
||||
|
||||
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example:
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release --set image.tag=v0.2.1 stable/g2
|
||||
```
|
||||
|
||||
Alternatively, a YAML file that specifies the values for the parameters can be provided while
|
||||
installing the chart. For example:
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release --values values.yaml stable/g2
|
||||
```
|
||||
|
||||
## RBAC
|
||||
By default the chart will not install the recommended RBAC roles and rolebindings.
|
||||
|
||||
You need to have the following parameter on the api server. See the following document for how to enable [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)
|
||||
|
||||
```
|
||||
--authorization-mode=RBAC
|
||||
```
|
||||
|
||||
To determine if your cluster supports RBAC, run the the following command:
|
||||
|
||||
```console
|
||||
$ kubectl api-versions | grep rbac
|
||||
```
|
||||
|
||||
If the output contains "alpha" and/or "beta", you can may install the chart with RBAC enabled (see below).
|
||||
|
||||
### Enable RBAC role/rolebinding creation
|
||||
|
||||
To enable the creation of RBAC resources (On clusters with RBAC). Do the following:
|
||||
|
||||
```console
|
||||
$ helm install --name my-release stable/g2 --set rbac.install=true
|
||||
```
|
||||
|
||||
### Changing RBAC manifest apiVersion
|
||||
|
||||
By default the RBAC resources are generated with the "v1beta1" apiVersion. To use "v1alpha1" do the following:
|
||||
|
||||
```console
|
||||
$ helm install --name my-release stable/g2 --set rbac.install=true,rbac.apiVersion=v1alpha1
|
||||
```
