One of the main goals of the CMaNGOS Docker project is optimization.
To achieve this, two different types of images have been developed: the one used for maintainance (larger) and the one used for execution.

With this principle in mind, we can now begin! 🚀

First of all, you have to decide up to which client version you want your server to support.
Both CMaNGOS and CMaNGOS Docker use three keywords to identify it; select the one you need and keep it in mind for the next steps:

• classic → World of Warcraft® v1.12.x
• tbc → World of Warcraft: The Burning Crusade® v2.4.3
• wotlk → World of Warcraft: Wrath of the Link King® v3.3.5a

Once you've selected the supported client version, you can download the related Docker images.
To do so, you need to open a shell or command prompt and type the following lines replacing the <version> placeholder with the keyword of your choice:

docker pull ghcr.io/byloth/cmangos/<version>:latest
docker pull ghcr.io/byloth/cmangos/<version>/builder:latest

docker pull ghcr.io/byloth/cmangos/tbc:latest
docker pull ghcr.io/byloth/cmangos/tbc/builder:latest

Actually, due to legal reasons and copyright policies, CMaNGOS (and -of course- CMaNGOS Docker) cannot be distributed ready-to-run (or -at least- not at 100% of its functionality)...
In fact, it needs some extra copyrighted files from Blizzard Entertainment®.

These files -on the other hand- are present within the WoW client: the same client you need to play.
For this reason, if you've purchased and legally own a copy of the client, you can use a tool to extract these files directly from it.
