How to setup docker container using VirtEngine

Introduction

Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in.

This tutorial we will need to setup the docker container.

Prerequisites

• You require atleast one swarm master and lots of node(s).

• The nodes must have our package verticedocker installed with linux configured.

• The linux bridge needs to configured in each of the hosts

Swarm Install

Now, on your master which is soon going to be swarm master, install megamswarm

apt-add-repository "deb [arch=amd64  https://get.megam.io/1.0/ubuntu/14.04/ trusty testing"

apt-key adv --keyserver keyserver.ubuntu.com --recv B3E0C1B7

apt-get update

apt-get install megamswarm

start megamswarm

Install dockercontainer in node

 echo 'deb https://apt.dockerproject.org/repo ubuntu-trusty main' >/etc/apt/sources.list.d/docker.list

  apt-get install apt-transport-https ca-certificates

  apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

  apt-get install linux-image-generic-lts-trusty

  apt-get update

  apt-get install docker-engine

  apt-get install verticecommon verticegulpd verticedocker

edit your /usr/share/megam/verticegulpd/conf/gulpd.conf

start your node verticegulpd

  start verticegulpd

Create Bridge

To install bridge on your node

   apt-get install bridge-utils

Edit your /etc/network/interface file

   auto megdock
   iface megdock inet static
   address   xxx.xxx.xxx.xxx
   netmask   yyy.yyy.yyy.yyy
   bridge_ports none
   bridge_stp off
   bridge_fd 1
   bridge_hello 2
   bridge_maxage 12
   up ip route add zzz.zzz.zzz.zzz/27 dev megdock

Then create megdock bridge

 brctl add-br megdock

check if a linux bridge by name megdock exists

brctl show

start your docker daemon

docker daemon -D -H tcp://nodeip:2375 #### To join the nodes to the swarm master

We need a token to join the nodes to the swarm master. You should find this line following the command

 ps -ef | grep swarm

 root     129993 129353  0 11:07 pts/0    00:00:01 swarm join --addr=xxx.xxx.xxx.xxx:2375 token://54c729c18d379721c9483c07e071b7e9

Copy the token to join nodes to swarm master and paste the token. Then execute the below command on the master to join node to master

swarm join --addr=<node_ip>:2375 token://54c729c18d379721c9483c07e071b7e9

Hopefully you have configured our engine vertice engine, if not this is needed for the launch

nano /usr/share/megam/megamd/megamd.conf
swarm:
   host: https://<swarm_master_ip>:2375

Voila! Go ahead and launch multiple docker containers through vertice.

Conclusion

Finally swarm and dockernode installed setup on your host by docker container using vertice and successfully launched the docker container
