# Install with POC configuration

{% hint style="info" %}
StackState prefers Kubernetes!\
In the future we will move away from Linux support. Read how to [migrate from the Linux install of StackState to the Kubernetes install](https://archivedocs.stackstate.com/5.1/setup/install-stackstate/kubernetes_openshift/migrate_from_linux).
{% endhint %}

Proof-of-concept (POC) mode is StackState's installation mode best suited for POCs. It requires only one machine, and can handle (almost) the same load as a regular production setup. The only limitations are that the system cannnot handle lots of perpetual data (like >10 agents or a big perpetually running AWS landscape).

## Requirements

Before starting the installation, ensure your system meet StackState's POC setup [installation requirements](https://archivedocs.stackstate.com/5.1/setup/install-stackstate/requirements).

## Installing StackState in a POC configuration

For a POC setup of StackState, simply follow the instructions for [Installing StackState](https://archivedocs.stackstate.com/5.1/setup/install-stackstate/linux/install_stackstate), using `POC` as the SETUP configuration parameter.

## Starting and Stopping

### SystemD service

The RPM and DEB packages install SystemD services for StackState and StackGraph. StackState can be started with `sudo systemctl start stackstate.service` this will also start service StackGraph. Starting StackState can take some time.

After starting processes are complete, the service is available at `http://<stackstate_hostname>:7070`.

### Stopping StackState

StackState can be stopped by `sudo systemctl stop stackstate.service`. StackGraph isn't automatically stopped when stopping StackState, StackGraph can be stopped by `sudo systemctl stop stackgraph.service`.

### StackState Status

Checking the service status can be done with `sudo systemctl status stackstate.service` and `sudo systemctl status stackgraph.service`.
