Docker

Revision as of 19:39, 30 January 2016

My little page about getting docker to run, done by somebody having no idea what docker is.

Yeah, DAU-docker!

ATTENTION this uses default passwords, and is completely unsecure !!!!

First install docker

• sudo apt-get install docker.io
• sudo usermod -a -G docker $(id -un)
• # logoout/login to get your group attribution

Mediawiki

Create a database

• # no idea what this does, I just pasted it from https://hub.docker.com/_/mysql/
• docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:latest

Create a mediawiki

• # well probably something like found here https://hub.docker.com/r/synctree/mediawiki/
• docker run --name some-mediawiki --link some-mysql:mysql -p 8080:80 -d synctree/mediawiki

• firefox http://localhost:8080/
  • database host: mysql
  • database name: mysql
  • table prefix: mw
  • username: root
  • password: my-secret-pw
  • at end of setup you get a LocalSettings.php to download
  • this file has to be provided to the docker or put into the container. Seems to be several ways to do it, but none work. So this one works:
• cat LocalSettings.php | docker exec -i some-mediawiki sh -c 'cat > /var/www/html/LocalSettings.php'
• docker exec -i some-mediawiki chown www-data:www-data /var/www/html/LocalSettings.php
• docker exec -i some-mediawiki chmod 444 /var/www/html/LocalSettings.php
• firefox http://localhost:8080/index.php

More help: well the usual mediawiki help

Engelsystem

Grabbed infos from https://hub.docker.com/r/whiledo/engelsystem-fhmuc-tool/

Make a DB

• docker run --name mysql-engelsystem -e MYSQL_ROOT_PASSWORD=my-secret-pw -p 3306:3306 -d mysql

Setup engels. This is not tested, just plastered together in hope that it works

• docker run -d -p 9090:80 -e mysqlhost="loclahost" --link mysql-engelsystem:mysql -e installmysql="yes" whiledo/engelsystem-fhmuc-tool
• firefox http://localhost:9090/

If running the docker again, do not give the '-e installmysql="yes" ' part
