+# Mosquitto: A small MQTT broker
+
+This is a helm chart for [mosquitto](https://mosquitto.org/)
+
+## TL;DR;
+
+```shell
+$ helm repo add k8s-at-home https://k8s-at-home.com/charts/
+$ helm install k8s-at-home/mosquitto
+```
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+helm install --name my-release k8s-at-home/mosquitto
+```
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```console
+helm delete my-release --purge
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+Read through the [values.yaml](https://github.com/k8s-at-home/charts/blob/master/charts/mosquitto/values.yaml) file. It has several commented out suggested values.
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```console
+helm install --name my-release \
+  --set persistence.enabled=true \
+    k8s-at-home/mosquitto
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
+
+```console
+helm install --name my-release -f values.yaml k8s-at-home/mosquitto
+```

+Mosquitto can be accessed within the cluster on port 1883 at {{ template "mosquitto.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
+
+To access for outside the cluster, perform the following steps:
+
+{{- if contains "NodePort" .Values.service.type }}
+
+Obtain the NodePort IP and ports:
+
+    export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
+    export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[1].nodePort}" services {{ template "mosquitto.fullname" . }})
+
+To Access the Mosquitto MQTT port:
+
+    echo "URL : amqp://$NODE_IP:$NODE_PORT/"
+
+{{- else if contains "LoadBalancer" .Values.service.type }}
+
+Obtain the LoadBalancer IP:
+
+NOTE: It may take a few minutes for the LoadBalancer IP to be available.
+      Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "mosquitto.fullname" . }}'
+
+    export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "mosquitto.fullname" . }} --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}}")
+
+To Access the Moquitto port:
+
+    echo "URL : mqtt://$SERVICE_IP:1883/"
+
+{{- else if contains "ClusterIP"  .Values.service.type }}
+
+To Access the Mosquitto MQTT port:
+
+    kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ template "mosquitto.fullname" . }} 1883:1883
+    echo "URL : mqtt://127.0.0.1:1883/"
