On your VirtualBox install an Oracle UEK 7.9 server using this DVD, which you have downloaded first: Oracle 7.9 DVD

As root perform

yum update
reboot now
yum install epel

If you want a graphical interface do this:

yum -y groupinstall kde "KDE Plasma Workspaces"
yum install kernel-headers kernel-devel make gcc perl dkms bzip2
yum grouplist
yum groupinstall "Server with GUI"
cd /etc/systemd/system/                                                                                 
ln -s /usr/lib/systemd/system/                                           
reboot now

Now install docker. First edit /etc/yum.repos.d/oracle-linux-ol7.repo change 0 til 1 in the section [ol7_addons], save and execute:

yum install docker-engine docker-cli docker-compose

Let your favourite browser open the team github page from the students that constrructed this server setup.

Create under root a directory called e.g. elab-server

mkdir elab-server	
git clone

Start docker

systemctl enable docker.service
systemctl start docker.service

create volumens

docker volume create data-volume
docker volume create mqtt-volume

Change version number in the docker-compose.yml file from 3.7 to 3.3

docker-compose up -d --build

be sure that it ends without errors - if, then try to run it again. It takes quite a while! (on my 6 core virtual machine more than one hour)

More to come...
