# Environment Setup

<Badge color="gray">Fortytwo P2P Container</Badge>

Before the Inference Node can be launched with the **Fortytwo P2P Container**, the `.env` file has to be set up first.

*If you haven't set it up during the '[Quick Start](/docs/quick-start)' stage, copy and rename the `.env.example` reference file or create empty `.env` file and fill with the following placeholder data:*

<Accordion title="Unwrap for `.env` file placeholder content">
  ```bash theme={null}
  # protocol
  FT_ACCOUNT_PRIVATE_KEY=
  FT_NODE_LISTENER_PORT=42042

  # capsule 
  FT_CAPSULE_HTTP_HOST="0.0.0.0"
  FT_CAPSULE_HTTP_PORT=42442
  FT_CAPSULE_LLM_HF_REPO=
  FT_CAPSULE_LLM_HF_MODEL_NAME=

  INPUT_MODEL_CACHE=./model_cache
  ```
</Accordion>

## Environment Parameters

### `FT_ACCOUNT_PRIVATE_KEY`

Paste in the private key of an **EVM-compatible Web3 account**.

* Your Web3 account **should be unqie for each node that you run simultaniously**. This applies to both Inference and Relay nodes.<br />*For example: if you intend to run **8 nodes** on **8×GPU rig** at the same time, you'll need **8 private keys**.*
* **Keep your Private Key secure.** Never share it publicly or commit it to version control systems.

### `FT_NODE_LISTENER_PORT`

Default port is `42042`. Change it if necessary.

* If another process in the system is using this port, for example, a **Relay Node is running on the same machine**, then change this port for the Inference Node.
* If running several Inference Nodes on the same machine at the same time, each of them should have its own unique port defined.
* The defined prots should not be occupied by other processes in the system.
* It must be different from the `FT_RPC_SERVICE_PORT`.

### `FT_CAPSULE_HTTP_PORT`

Default port is `42442`. Change it if necessary.

* If another process in the system is using this port, for example, a **Relay Node is running on the same virtual machine**, then change this port for the Inference Node.
* It must be different from the `FT_NODE_LISTENER_PORT`.
