DoMaLiMa

Docker Matlab License Manager

Introducing

DoMaLiMa let you build, silent-install and run an dockerized Matlab-FlexLM-Manager which can be reached from all other hosts in your network.

You can spawn only one or how much are needed to fullfill your license-quorum.

For this example we will use three containers

Because of the fact, that you can give an Docker-Container every Mac-Address it is easy to port the License-Manager quickly to some other Server without deactivating the License

Installation

Software

This Repository

Clone this repository to an location that fits your needs and cd into the newly created directory.

Copy your license.dat file in here and replace it with the placeholder license.dat

Also, don't forget to set your fileInstallationKey in installer_input.txt

marked with:

fileInstallationKey=$PUT-YOUR-KEY-HERE

---

MatLab R2017a

Download your version of Matlab (@time of writing this is R2017a) here

Unzip it into DoMaLiMa/, so that it looks something like DoMaLiMa/matlab_R2017a_glnxa64 according to your downloaded version

Host Settings

In order for Docker to be able to listen to real network-adresses on your network, we use virt. interfaces and map them to the container during the 'docker run'-command.

Set virt. Interfaces on Host(s) like this:

Put in /etc/network/interfaces, or wherever your distribution holds Interface-Config-Files

Change settings according to your needs

auto eth0:1
allow-hotplug eth0:1
iface eth0:1 inet static
        address 192.168.1.241
        netmask 255.255.255.0
        gateway 192.168.1.1
        dns-nameservers 192.168.1.1
        dns-search example.org

auto eth0:2
allow-hotplug eth0:2
iface eth0:2 inet static
        address 192.168.1.242
        netmask 255.255.255.0
        gateway 192.168.1.1
        dns-nameservers 192.168.1.1
        dns-search example.org

auto eth0:3
allow-hotplug eth0:3
iface eth0:3 inet static
        address 192.168.1.243
        netmask 255.255.255.0
        gateway 192.168.1.1
        dns-nameservers 192.168.1.1
        dns-search example.org

afterwards

sudo ifup eth0:1 eth0:2 eth0:3

to bring up the interfaces.

Preparing Docker Images

If there are old Container running, ...

stop them, ...

docker stop license01 license02 license03

remove them

docker rm license01 license02 license03

---

Rebuild the Container

Now you can build the Container with:

docker build -t hsteininger/domalima .

If you're behind a Proxy you can use --build-args to set a Proxy

docker build --build-arg HTTP_PROXY=http://YOUR-HTTP-PROXY:80/ \
             --build-arg HTTPS_PROXY=http://YOUR-HTTPS-PROXY:443/ \
             --build-arg FTP_PROXY=http://YOUR-FTP-PROXY:80/ \
             -t hsteininger/domalima .

---

Run Container

Keep hostname, mac-address and IP-Portmapping, because of MatLab-License-Host-Mapping

Set Port and Mac-Adress according to your 'license.dat'

license01

docker run -itd --restart unless-stopped -p 192.168.1.241:27000-27001:27000-27001 \
            --mac-address="00:00:00:00:00:01" -h license01 --name=license01 \
            hsteininger/domalima

license02

docker run -itd --restart unless-stopped -p 192.168.1.242:27000-27001:27000-27001 \
            --mac-address="00:00:00:00:00:02" -h license02 --name=license02 \
            hsteininger/domalima

license03

docker run -itd --restart unless-stopped -p 192.168.1.243:27000-27001:27000-27001 \
            --mac-address="00:00:00:00:00:03" -h license03 --name=license03 \
            hsteininger/domalima

Get Status From Hosts

docker exec license01 /usr/local/MatLab/2017a/etc/lmstat -c /usr/local/MatLab/2017a/etc/license.dat -a
docker exec license02 /usr/local/MatLab/2017a/etc/lmstat -c /usr/local/MatLab/2017a/etc/license.dat -a
docker exec license03 /usr/local/MatLab/2017a/etc/lmstat -c /usr/local/MatLab/2017a/etc/license.dat -a

If you need to attach to an Container

docker attach license01
docker attach license02
docker attach license03

To quit from an attached container press ctrl-p+q
