Minecraft is a game about breaking and placing blocks. Originally a sandbox video game created by Swedish programmer Notch, Minecraft is now developed and published by Mojang. Integrating exploration, resource gathering, crafting, and combat into a rewarding experience, Minecraft stays fresh through hours of play. Multiplayer provides yet another layer of depth as players band together to create vast structures beyond your imagination.
With this bundle anyone can easily deploy their own Minecraft server, easily accessible from the Minecraft launcher for play with friends or strangers.
These should be routine by now:
By default, the stack deploys on an instance of type “Small” (s1.cw.small-1). A variety of other instance types exist to suit your various needs, allowing you to pay only for the services you need. Instances are charged by the minute and capped at their monthly price (you can find more details on the Tarifs page on the Cloudwatt website).
Stack parameters, of course, are yours to tweak at your fancy.
Once you have cloned the github repository, you will find in the bundle-trusty-minecraft/ directory:
bundle-trusty-minecraft.heat.yml: Heat orchestration template. It will be use to deploy the necessary infrastructure.stack-start.sh: Stack launching script, which simplifies the parameters and secures the admin password creation.minecraft-server-address.sh: Returns the floating-IP in a URL, which can also be found in the stack output.
Have your Cloudwatt credentials in hand and click HERE. If you are not logged in yet, complete the authentication and save the credentials script. With it, you will be able to wield the amazing powers of the Cloudwatt APIs.
Source the downloaded file in your shell and enter your password when prompted to begin using the OpenStack clients.
$ source COMPUTE-[...]-openrc.sh
Please enter your OpenStack Password:
Once this done, the Openstack command line tools can interact with your Cloudwatt user account.
In the .heat.yml files (heat templates), you will find a section named parameters near the top. The mandatory parameters are the keypair_name and the admin_username for the Minecraft op user.
You can set the keypair_name’s default value to save yourself time, as shown below.
Remember that key pairs are created from the console, and only keys created this way can be used.
The admin_username field provides the username for Minecraft’s default op user. You will need it to set other players as op and use administrative commands. You can also adjust (and set the default for) the instance type by playing with the flavor parameter accordingly.

Creating stack...

| id | stack_name | stack_status | creation_time |
+--------------------------------------+------------+--------------------+----------------------+

Within 5 minutes the stack will be fully operational. (Use watch to see the status in real-time)
$ watch -n 1 heat stack-list
+--------------------------------------+------------+-----------------+----------------------+
| id | stack_name | stack_status | creation_time |
+--------------------------------------+------------+-----------------+----------------------+
| xixixx-xixxi-ixixi-xiixxxi-ixxxixixi | GOLDDIGGER | CREATE_COMPLETE | 2025-10-23T07:27:69Z |
+--------------------------------------+------------+-----------------+----------------------+
Once all of this done, you can run the minecraft-server-address.sh script.
$ ./minecraft-server-address.sh GOLDDIGGER
GOLDDIGGER 70.60.637.17
As shown above, it will display the assigned address of your minecraft server. You can then click or paste this into Minecraft and bask in the glory of a fresh Minecraft server.
There there, it’s okay… Minecraft stacks can be spawned from our console as well!
To create our Minecraft stack from the console:
bundle-trusty-minecraft.heat.ymlThe stack will be automatically generated (you can see its progress by clicking on its name). When all modules become green, the creation will be complete.
The goal of this tutorial is to accelerate your start. At this point you are the master of the stack. The default game mode is survival, but the admin can change that. Go to multiplayer and enjoy yourself!
This bundle deploys a stable Minecraft setup for use in fun, non-critical setups. None of the components are redundant but it is resource-light and quick to launch.

Have fun. Hack in peace.
