# Alfresco Content Services Helm Deployment with Docker For Desktop
# Alfresco Content Services Helm Deployment on local machines

This page describes how to deploy Alfresco Content Services (ACS) Enterprise or Community using [Helm](https://helm.sh) onto [Docker for Desktop](https://docs.docker.com/desktop/).
This page describes how to deploy Alfresco Content Services (ACS) Enterprise or Community using [Helm](https://helm.sh) onto [Rancher Desktop](https://rancherdesktop.io/) and [Docker for Desktop](https://docs.docker.com/desktop/).

## Prerequisites

- You've read the projects [main README](/README.md#prerequisites) prerequisites section
- You've read the [main Helm README](./README.md) page
- You are proficient in Kubernetes
- A machine with at least 16GB memory
- [Docker for Desktop](https://docs.docker.com/desktop/) for container management installed
- Latest version of [Kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl) is installed
- Latest version of [Helm](https://helm.sh/docs/intro/install) is installed
- Having installed either of:
- [Rancher for Desktop](https://rancherdesktop.io/). Includes kubectl and Helm, ready to use right after installation.
- [Docker for Desktop](https://docs.docker.com/desktop/). Requires separate install of kubectl and Helm.

The following instructions are also applicable to [Rancher Desktop](https://rancherdesktop.io/) users. Rancher desktop will provide `kubectl` and `helm` out of the box. it is open source but less mature than Docker desktop.

## Configure Docker for Desktop

In order to deploy onto Docker for Desktop we need to configure it with as much CPU and memory as possible on the "Resources" tab in Docker for Desktop's preferences pane as shown in the screenshot below. Similar resource requirement apply to Rancher Desktop.
### Rancher Desktop specific configuration

![Resources](./diagrams/dfd-resources.png)
Uncheck `Enable Traefik` from the `Kubernetes Settings` page to disable the default ingress controller. You may need to exit and restart Rancher Desktop for the change to take effect. Ref: [Setup NGINX Ingress Controller](https://docs.rancherdesktop.io/how-to-guides/setup-NGINX-Ingress-Controller)

### Docker for Desktop specific configuration
### Docker Desktop specific configuration

To deploy the Helm charts Kubernetes needs to be enabled, this can be done from the "Kubernetes" tab, as shown in the screenshot below. Press the "Apply & Restart" button to confirm.
On top of the Docker desktop [Prerequisites](./desktop-deployment.md#Prerequisites), it is essential to install the latest version of [Kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl) & [Helm](https://helm.sh/docs/intro/install).

![k8s Enabled](./diagrams/dfd-k8s-enabled.png)
After the installation of Docker Desktop, the following configurations should be adjusted within Docker Desktop settings.

### Rancher Desktop specific configuration
- `Settings > Resources > Advanced > CPUs:8, Memory: 16GB, Swap: 1GB`
- `Settings > kubernetes > Enable Kubernetes`

Uncheck `Enable Traefik` from the `Kubernetes Settings` page to disable Traefik. You may need to exit and restart Rancher Desktop for the change to take effect. Ref: [Setup NGINX Ingress Controller](https://docs.rancherdesktop.io/how-to-guides/setup-NGINX-Ingress-Controller)
After changing the necessary settings `Apply and restart` the docker desktop.

## Deploy

Once Docker for Desktop is running follow the steps in the following sections to deploy ACS (Enterprise or Community) to your local machine.
Please proceed to execute the instructions detailed in the following sections for the installation of ACS (Enterprise or Community edition) on your local system.

### Namespace

Namespaces in Kubernetes isolate workloads from each other, create a namespace to host ACS inside the cluster using the following command (we'll then use the `alfresco` namepsace throughout the rest of the tutorial):
To establish an isolated environment for ACS within the Kubernetes cluster, initiate the creation of a Kubernetes namespace using the provided command. Throughout the subsequent sections of this tutorial, we will consistently refer to this namespace as 'alfresco'

Add the chart repository using the following command:
Add the ingress-nginx chart repository:

```bash
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update

## Troubleshooting
If your deployment fails it's most likely to be caused by resource limitations, please refer to the sections below for more information. Please also consult the [Helm Troubleshooting section](./README.md#Troubleshooting) for more generic troubleshooting tips and tricks.
In the event of a deployment failure, it is important to recognize that resource constraints are a common underlying cause. For further insights and guidance. Additionally, you can find more comprehensive troubleshooting advice in the [Helm Troubleshooting section](./README.md#Troubleshooting)
### Lack Of Resources
The most common reason for deployment failures with Docker for Desktop is lack of memory or disk space. Check the "Resources" tab in Docker for Desktop's preferences pane, increase the allocation if you can and re-try.
One of the most prevalent causes of deployment failures is insufficient memory or CPU resources. It is imperative to ensure that an adequate amount of resources is allocated to prevent deployment failures.
To save the deployment of two more pods you can also try disabling the Sync Service, to do that provide the additional `--set` option below with your helm install command:
