====== TrisulNSM Docker image on Ubuntu 16.04 ======


This article describes how you can go from a bare install of Ubuntu 16.04 to a fully running Trisul NSM system quickly.  


===== Install Docker CE on Ubuntu 16.04 =====

The docker installation is very straightforward on Ubuntu 16.04 as it is an officially supported distribution. The official instructions [[https://docs.docker.com/install/linux/docker-ce/ubuntu/#set-up-the-repository|"Get Docker CE for Ubuntu"]] work great. Just follow those instructions. 

<code bash>
$ sudo apt-get install docker-ce
</code>



===== Start the Docker service =====

After installing Docker CE you need to start the service. 

<code bash>

systemctl start docker

</code>

===== Pull the trisulnsm/trisul6 Docker image  =====

The following command pulls the latest TrisulNSM image from Docker Hub but does not start anything.

<code bash>
sudo docker pull trisulnsm/trisul6 
</code>


===== Run TrisulNSM on eth0  =====

The following command starts the TrisulNSM Docker image with the following properties

  - Captures from interface ''eth0''
  - Stores persistent data in ''/opt/trisul6_root''
  - Names the container ''trisul1a'' for ease of use


<code bash>

sudo docker run --name=trisul1a  \ 
   --net=host -v /opt/trisul6_root:/trisulroot \
      --d trisulnsm/trisul6 \
          --interface  eth0
