Spin up your Mesos Cluster with Vagrant!
- Using VirtualBox
- Using Amazon EC2
The mesos installation is provided by mesos chef cookbook. Please see everpeace/cookbook-mesos.
- vagrant 1.2+ and <1.5: http://www.vagrantup.com/
- vagrant-berkshelf plugin is not compatible to vagrant 1.5. see the issue
- VirtualBox: https://www.virtualbox.org/ (not required if you use ec2.)
- vagrant plugins
- vagrant-omnibus
$ vagrant plugin install vagrant-omnibus - vagrant-berkshelf
$ vagrant plugin install vagrant-berkshelf - vagrant-hosts
$ vagrant plugin install vagrant-hosts - vagrant-cachier
$ vagrant plugin install vagrant-cachier - vagrant-aws (only if you use ec2.)
$ vagrant plugin install vagrant-aws
- vagrant-omnibus
It's so simple!
$ cd standalone
$ vagrant up
After box is up, you can see
- mesos web UI on: http://192.168.33.10:5050
- marathon web UI on: http://192.168.33.10:8080
if everything went well.

configure ec2 credentials and some settings defined in
standalone/aws_config.yml. You have to fill upEDIT_HEREparts. Security group you'll set must accept at least tcp port 22(SSH) and 5050(mesos-master web ui) from outside of ec2.# Please set AWS credentials access_key_id: EDIT_HERE secret_access_key: EDIT_HERE # please choose one from # ["ap-northeast-1", "ap-southeast-1", "eu-west-1", "sa-east-1", "us-east-1", # "us-west-1", "ap-southeast-2", "us-west-2"] region: us-east-1 # array of security groups. e.g. ['sg*** '] security_groups: EDIT_HERE # see http://aws.amazon.com/ec2/instance-types/#selecting-instance-types # for other instance types and its specs. instance_type: m1.small keypair_name: EDIT_HERE ssh_private_key_path: EDIT_HERE -
you can spin up mesos box on ec2 by the same way with the case of virtual box
cd standalone vagrant up --provider awsAfter box is up, you can see
- mesos web UI on:
http://#_public_dns_of_the_VM_#:5050 - marathon web UI on:
http://#_public_dns_of_the_VM_#:8080
if everything went well.
Tips: you can get public dns of the vm by:
$ vagrant ssh -- 'echo http://`curl --silent http://169.254.169.254/latest/meta-data/public-hostname`:5050' http://ec2-54-193-24-154.us-west-1.compute.amazonaws.com:5050 - mesos web UI on:
Cluster configuration is defined at cluster.yml. You can edit the file to congigure cluster configurations.
# Mesos cluster configurations

This takes several minutes(10 to 20 min.). It's time to go grabbing some coffee.
$ cd multinodes
$ ./vagrant up
At default seeting, after all the boxes are up, you can see
- mesos web UI on: http://172.31.1.11:5050
- marathon web UI on: http://172.31.3.11:8080
if everything went well.
this operations all VM instances forming the cluster.
$ cd multinodes
$ ./vagrant destroy
Because we require to assign private IP addreses to VM instances, this Vagrantfile uses Amazon VPC (you'll have to set subnet_id and security grooups both associated to the same VPC instance).
Note: Using default VPC is highly recommended. If you used non-default vpc, you should make sure that limit of the elastic ips is no less than (zk_n + master_n + slave_n). The limit default is 5.
You have to configure some additional stuff on cluster.yml related to EC2. Please note that
- subnet_id should be a VPC subnet
- security groups should be ones associated to the VPC instance.
- security groups should allow accesses to ports 22(SSH), 2181(zookeeper) and 5050--(mesos).

After editting configuration is done, you can just hit regular command.
$ cd multinode
$ vagrant up --provision aws (--no-parallel)
After instances are all up, you can see
- mesos web UI on:
http://#_public_dns_of_the_master_N_#:5050 - marathon web UI on:
http://#_public_dns_of_marathon_#:8080
if everything went well.
Tips: you can get public dns of the vms by:
$ vagrant ssh master1 -- 'echo http://`curl --silent http://169.254.169.254/latest/meta-data/public-hostname`:5050'
http://ec2-54-193-24-154.us-west-1.compute.amazonaws.com:5050
CAUTION: due to MESOS-672, mesos web ui fails redirection to the present leader of mesos master. So, you would need to access each master web ui manually to find the leader.
If you wanted to make sure that the specific mastar(e.g. master1) could be an initial leader, you can cotrol the order of spinning up vm like below.
$ cd multinode
# spin up an zookeeper ensemble
$ vagrant up --provider aws /zk/
# spin up master1. master1 will be an initial leader
$ vagrant up --provider aws master1
# spin up remained masters
$ vagrant up --provider aws /master[2-9]/
# spin up slaves
$ vagrant up --provider aws /slave/
$ cd multinodes
$ vagrant halt
$ cd multinodes
$ vagrant reload --provision
this operations terminates all VMs instances forming the cluster.
$ cd multinodes
$ vagrant destroy
