# Docker 🐋

Docker is the preferred way to run AdventureLog on your local machine. It is a lightweight containerization technology that allows you to run applications in isolated environments called containers.

> **Note**: This guide mainly focuses on installation with a Linux-based host machine, but the steps are similar for other operating systems.

## Prerequisites

- Docker installed on your machine/server. You can learn how to download it [here](https://docs.docker.com/engine/install/).

## Getting Started

Get the `docker-compose.yml` and `.env.example` files from the AdventureLog repository. You can download them here:

- [Docker Compose](https://github.com/seanmorley15/AdventureLog/blob/main/docker-compose.yml)
- [Environment Variables](https://github.com/seanmorley15/AdventureLog/blob/main/.env.example)

```bash
wget https://raw.githubusercontent.com/seanmorley15/AdventureLog/main/docker-compose.yml
wget https://raw.githubusercontent.com/seanmorley15/AdventureLog/main/.env.example
cp .env.example .env
```

::: tip

If running on an ARM based machine, you will need to use a different PostGIS Image. It is recommended to use the `tobi312/rpi-postgresql-postgis:15-3.3-alpine-arm` image or a custom version found [here](https://hub.docker.com/r/tobi312/rpi-postgresql-postgis/tags). The AdventureLog containers are ARM compatible.

The `.env` file contains all the configuration settings for your AdventureLog instance. Here’s a breakdown of each section:
