# Run AzerothCore with Docker

*This readme it's a summary of the AzerothCore docker features.*

Docker. is a software that performs operating-system-level virtualization, allowing to wrap and launch applications inside containers.

Thanks to Docker, you can quickly setup and run AzerothCore in any operating system.

The **only** requirement is having Docker installed into your system. Forget about installing mysql, visual studio, cmake, etc...

### Installation instructions

To install AzerothCore using Docker, you have to follow these steps (**respecting the order**):

1) Install [Docker](https://docs.docker.com/install/).

2) Create a Docker Network: `docker network create ac-network`. All your docker containers will use it to communicate to each other.

3) Launch one instance of the [AzerothCore Dockerized Database](https://github.com/azerothcore/azerothcore-wotlk/tree/master/docker/database)

4) Create an image of the [AzerothCore Dockerized Build](https://github.com/azerothcore/azerothcore-wotlk/tree/master/docker/build)

5) Launch one instance of the [AzerothCore Dockerized Authserver](https://github.com/azerothcore/azerothcore-wotlk/tree/master/docker/authserver)

6)  Launch one instance of the [AzerothCore Dockerized Worldserver](https://github.com/azerothcore/azerothcore-wotlk/tree/master/docker/worldserver)


### Memory usage

The total amount of RAM when running all AzerothCore docker containers is **less than 2 GB**.
