Minecraft Server Using Docker Compose

📙 The complete installation guide is available on my website.

❗ Change variables in the .env to meet your requirements.

💡 Note that the .env file and plugins folder should be in the same directory as minecraft-server-docker-compose.yml.

Create a network for your services before deploying the configuration using the command:

docker network create minecraft-server-network

Deploy Minecraft Server using Docker Compose:

docker compose -f minecraft-server-docker-compose.yml -p minecraft-server up -d

You can check the Minecraft Server status using the commands:

MINECRAFT_SERVER_CONTAINER=$(docker ps -aqf "name=minecraft-server-minecraft-server") \
&& docker exec -it $MINECRAFT_SERVER_CONTAINER mc-monitor status

Minecraft Servers Logs

You can check logs using the commands:

MINECRAFT_SERVER_CONTAINER=$(docker ps -aqf "name=minecraft-server-minecraft-server") \
&& docker logs $MINECRAFT_SERVER_CONTAINER

Minecraft Server Management

Apply new configuration after a change in the minecraft-server-docker-compose.yml or .env using the command:

docker compose -f minecraft-server-docker-compose.yml -p minecraft up -d

Connect to the Minecraft server command-line interface using the command:

MINECRAFT_SERVER_CONTAINER=$(docker ps -aqf "name=minecraft-server-minecraft-server") \
&& docker exec -i $MINECRAFT_SERVER_CONTAINER rcon-cli

Backups

The backups container in the configuration ensures a consistent backup routine for the Minecraft server. Here's a detailed breakdown:

• Connection to Minecraft Server:

  • The container communicates with the main Minecraft server through RCON (Remote Console) for server management.
  • Specified by: RCON_HOST

• Backup Schedule:

  • Determines the frequency of backups.
  • Specified by: BACKUP_INTERVAL

• Backup Pruning:

  • Older backups are removed periodically to manage storage space.
  • Specified by: PRUNE_BACKUPS_DAYS

• Initial Delay:

  • The container waits for a defined time before starting the backup routine.
  • Specified by: INITIAL_DELAY

• Backup Storage:

  • Defines the source of server data and backup storage location.
  • Backup location: MINECRAFT_SERVER_BACKUPS_PATH

Restore (Init Container)

The restore container, described as an "init" container, serves a unique role:

• Functionality:

  • Mainly restores the data volume if found empty.

• Entry Point:

  • Specifies the primary action upon container startup.
  • Defined by: entrypoint (default: restore-tar-backup).

• Data Restoration:

  • Has access to the server data and backups for restoration purposes.
  • Backups source: MINECRAFT_SERVER_BACKUPS_PATH

By integrating this Docker Compose setup, it not only ensures consistent backups of the Minecraft server data but also offers efficient data restoration when needed. Flexible configuration options provide tailored backup routines catering to specific requirements, thereby guaranteeing data integrity and availability.
