+# Faktory Helm Chart
+
+[Faktory](https://github.com/contribsys/faktory) is an open-source background jobs server written on Golang. It have got clients for different programming languages.
+
+## TL;DR;
+
+```console
+$ helm install incubator/faktory
+```
+
+## Introduction
+
+This chart bootstraps a [Faktory](https://github.com/contribsys/faktory) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm install --name my-release incubator/faktory
+```
+
+The command above deploys Faktory 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` deployment:
+
+```console
+$ helm delete my-release
+```
+
+The command above removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+The following table lists the configurable parameters of the Faktory chart and their default values.
+
+Parameter | Description | Default
+--------- | ----------- | -------
+`image.repository` | faktory image repository | `contribsys/faktory`
+`image.tag` | faktory image tag | `1.0.0`
+`image.pullPolicy` | faktory image pullPolicy | `IfNotPresent`
+`service.type` | service type | `ClusterIP`
+`service.ui_port` | service port for WebUI | `80`
+`service.commands_port` | service port for commands | `80`
+`ingress.enabled` | If true, an ingress will be created for the api | `false`
+`ingress.annotations` | ingress annotations | `{}`
+`ingress.path` | ingress path | `/`
+`ingress.hosts` | ingress hostnames | `[]`
+`ingress.tls` | ingress TLS configuration | `[]`
+`resources` | resource requests and limits | `{}`
+`nodeSelector` | node selector labels for pod assignment | `{}`
+`tolerations` | toleration for pod assignment | `[]`
+`affinity` | affinity for pod assignment | `{}`
+`password` | WebUI Password | `password`
+`persistentVolume.enabled` | If true, create a Persistent Volume Claim | `true`
+`persistentVolume.accessModes` | Persistent Volume access modes | `ReadWriteOnce`
+`persistentVolume.annotations` | Annotations for Persistent Volume Claim | `{}`
+`persistentVolume.existingClaim` | Persistent Volume existing claim name | `""`
+`persistentVolume.size` | Persistent Volume size | `1Gi`
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```console
+$ helm install incubator/faktory --name my-release \
+    --set api.replicaCount=5
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
+
+```console
+$ helm install incubator/faktory --name my-release -f values.yaml
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
