MineOS Webui on Alpine Linux

The MineOS user interface can be installed on Alpine Linux systems using the apk package manager and either openrc-run or supervisord.

As written, these steps will install the webui with the following properties:

Installation steps

The following steps much be executed as root.

DEPENDENCIES

ALMOST EVERYTHING

# apk add git rdiff-backup screen rsync python3 g++ make
# apk add --no-cache --repository http://dl-cdn.alpinelinux.org/alpine/v3.10/main/ nodejs=10.19.0-r0 nodejs-npm=10.19.0-r0

JAVA

The following steps install openjdk16 into a neutral space (/opt) and then symlinks it to /usr/bin/java. Note, that so long as root has a java binary in its $PATH, any version you choose–and even different installation methods–are permissible. This particular openjdk binary is chosen because CentOS 8 does not yet have Java 16 available in its normal repos at time of writing.

# tar xf openjdk-16-jre.tgz
# mv jdk-16.0.* /opt/openjdk-16.0-jre
# ln -s /opt/openjdk-16.0-jre/bin/java /usr/bin/java
# rm openjdk-16-jre.tgz

DOWNLOAD WEBUI FILES

# cd /usr/games
# git clone https://github.com/hexparrot/mineos-node minecraft
# cd minecraft
# git config core.filemode false
# chmod +x generate-sslcert.sh mineos_console.js webui.js
# cp mineos.conf /etc/mineos.conf

BUILD NODE DEPENDENCIES

# cd /usr/games/minecraft
# npm install --unsafe-perm

USE HTTPS FOR SECURE TRANSPORT

# cd /usr/games/minecraft
# ./generate-sslcert.sh

SELECTING SERVICE INIT TYPE

Alpine Linux offers openrc-run by default, which you can use to have the webui start at boot. You may, alternatively, use supervisord–but be sure to only choose one.

OPENRC-RUN

# cp /usr/games/minecraft/init/openrc_conf /etc/init.d/mineos

Then, to manage the service:

# service mineos status
# service mineos start
# service mineos stop

SUPERVISORD

# apk add supervisord
# cp /usr/games/minecraft/init/supervisor_conf /etc/supervisor/conf.d/mineos.conf
# supervisorctl reload

Then, to manage the service:

# supervisorctl status mineos
# supervisorctl start mineos
# supervisorctl stop mineos

Usage

Once the background daemon is running, you can visit https://[ipaddress]:8443 in your web browser and you will see a user and password prompt. When creating minecraft and managing Minecraft servers, use an unprivileged user to log into the webui. Creating an unprivileged user (a user that is not root) can be accomplished with the adduser username command. The password you set during user creation will also be the password used for the web-ui.
