Vagrant dev environent setup with Mesos/Marathon/Chronos/Aurora/Jenkins/Docker
Disclaimer: This Vagrant setup consumes significant resources but runs fine on my 2013 Macbook Pro developer notebook with a 2.8 GHz Intel Core i7 processor and 16 GB RAM. It may not work as well on a machine with lesser hardware specs.
Run the following script which will launch 3 VMs each with all the components shown in the graphic above installed. To save time the script will install everything on the first VM, save it as a vbox image and then clone the remaining VMs from it.
$ ./create.sh
mesos1 ip address: 192.168.56.101
The main instance has the following services actively running upon startup and has 4GB allocated RAM:
1. Mesos master
2. Mesos slave
3. Zookeeper
4. Docker
5. Docker Executor
6. Jenkins
7. Marathon
8. Aurora
9. Chronos
Your cluster now effectively has 3 Mesos masters, 3 zookeepers and 3 Mesos slaves (each with Docker installed). Jenkins, Marathon, Chronos & Aurora are installed on the additional VMs too except that they have been disabled on startup. The additional Mesos instances have been allocated a lesser 2GB RAM each.
mesos2 ip address: 192.168.56.102
mesos3 ip address: 192.168.56.103
Each additional VM with the following services actively running upon startup:
1. Mesos master
2. Mesos slave
3. Zookeeper
4. Docker
ssh root@mesos1 | ssh root@mesos2 | ssh root@mesos3
Root SSH Credentials:
username: root
password: vagrant
Create these entries in the /etc/hosts file on the host machine for quick access to the VMs.
192.168.56.101 mesos1 jenkins1 marathon1 aurora1 chronos1
192.168.56.102 mesos2 jenkins2 marathon2 aurora2 chronos2
192.168.56.103 mesos3 jenkins3 marathon3 aurora3 chronos3
An Nginx HTTP proxy server is running on each machine so that you can access the applications on the respective VMs. Only one Mesos master is active at a time so you will be immediately redirected to the leading master.
