+# Alfresco Content Services Helm Deployment on KinD cluster
+
+This page describe how to get ACS up and running on a [Kubernetes In
+Docker](https://kind.sigs.k8s.io/) (KinD) cluster.
+
+KinD is better suited to run helm workloads inside CI environments but works
+well also for local development because it just requires a working Docker
+server.
+
+## Prerequisites
+
+- Docker installed on your machine (Docker Desktop, Rancher Desktop, Podman and similar)
+- Kubernetes CLI (kubectl) installed on your machine
+- Helm CLI installed on your machine
+
+## Step 1: Install Kind
+
+Take a look to the [KinD
+quickstart](https://kind.sigs.k8s.io/docs/user/quick-start/) to learn how to
+install the binary cli on your machine and to learn briefly the main commands
+that you can run.
+
+## Step 2: Create a Kind Cluster
+
+Run the following command to create a Kind cluster:
+
+```shell
+cat <<EOF | kind create cluster -n acs-testing --config=-
+kind: Cluster
+apiVersion: kind.x-k8s.io/v1alpha4
+nodes:
+- role: control-plane
+kubeadmConfigPatches:
+- |
+    kind: InitConfiguration
+    nodeRegistration:
+    kubeletExtraArgs:
+        node-labels: "ingress-ready=true"
+extraPortMappings:
+- containerPort: 80
+    hostPort: 80
+    protocol: TCP
+- containerPort: 443
+    hostPort: 443
+    protocol: TCP
+EOF
+```
+
+Wait for the Kind cluster to be created. This may take a few minutes.
+
+## Step 3: Install patched ingress-nginx
+
+Follow the instructions for
+[deploying nginx ingress on KinD](https://kind.sigs.k8s.io/docs/user/ingress/#ingress-nginx).
+
+Reconfigure ingress-nginx to allow snippet annotations that are still required
+when using our search services chart:
+
+```sh
+kubectl -n ingress-nginx patch cm ingress-nginx-controller \
+  -p '{"data": {"allow-snippet-annotations":"true"}}'
+```
+
+Wait for the ingress-nginx controller to be up again after the configuration change:
+
+```sh
+kubectl wait --namespace ingress-nginx \
+  --for=condition=ready pod \
+  --selector=app.kubernetes.io/component=controller \
+  --timeout=90s
+```
+
+## Install metrics server
+
+Optionally, you can [install metrics
+server](https://github.com/kubernetes-sigs/metrics-server#installation) to
+gather metrics from node and pods.
+
+Make sure to enable insecure tls option otherwise metrics collection would not work under KinD:
+
+```sh
+kubectl patch -n kube-system deployment metrics-server --type=json \
+  -p '[{"op":"add","path":"/spec/template/spec/containers/0/args/-","value":"--kubelet-insecure-tls"}]'
+```
+
+Wait for a few minutes and then try to run:
+
+```sh
+kubectl top node
+```
+
+Upon installing ACS, you can check current cpu and memory usage via:
+
+```sh
+kubectl top pods
+```
+
+## Conclusion
+
+Now that you have successfully set up a Kind cluster with ingress-nginx and
+metrics-server, you can now proceed with installing ACS via helm charts as per
+[Desktop deployment](desktop-deployment.md#acs).
