¶ Initial Steps
- If you have not yet done so, follow the steps to sign up for Netsoc Cloud in the Tutorial
¶ Instance Request
-
Create a Container instance request for the Docker image
- Choose the hostname as you wish (e.g.
minecraft,myminecraft,creeper) - Explain what you are using this instance for: a Minecraft server
- Choose the hostname as you wish (e.g.
-
Wait for the request to be accepted/denied
-
Request an upgrade to your specs via the Upgrade button ask for an adaquete amount of RAM:
- e.g. 1gb if you're looking for a 8-12 player server
¶ Accessing Instance
- Start your instance
- Reset the instance root user password via Reset Root
- Open the web Terminal and sign in using the
rootusername and password received in the email - You should now see something like this:
¶ Setting up the Minecraft Server
¶ Set up a port map
-
We plan on binding Minecraft to port
25565on our instance -
But we need it to be publicly available so we can join, therefore we need to do a port forward
-
Hit + Port and add a port map, which will map a free external port to your internal
25565 -
You will need to remember the external port listed here later
¶ Run Minecraft (inside Docker)
- Run the command:
docker run -d -p 25565:25565 -e ENABLE_AUTOPAUSE=TRUE -e EULA=TRUE --restart always --name mc itzg/minecraft-server:java17-openj9- This will download a Docker image (think of it like an easy way to package software)
- It will then run Minecraft and bind it to the port given
¶ Accessing the console
- Run
docker exec -i mc rcon-cliand then typehelpto see commands - Press Ctrl-C to exit the console
¶ Watch the server logs
- Run
docker logs mc --follow - Press Ctrl+C to stop following logs
¶ Connecting to the server
-
You can connect to the server by using your instance hostname and externally mapped port
-
For the screenshot above, the server and port to join would be
minecraft.ocanty.container.netsoc.cloud:17226 -
If your server appears down, you may need to connect to it once for it to appear online
¶ Important (autopause) functionality
- You configured this container to pause the server when no-one is on it
- This might occasionally cause you to have to connect to the server (that appears offline) at least once to boot it
- Once rebooted, the server should come up and you should be able to join
- Do NOT disable this functionality or we will consider it a ToS violation
- This is done to ensure that game servers do not take away resources from other users
