This is a fork of everpeace/vagrant-mesos, adding updated versions of Mesos and Marathon, and also adding new functionality with REX-Ray and DVDI.

Spin up your Mesos cluster with Vagrant! (Only AWS is supported currently.)

This spins up Mesos 0.23.0 cluster and also spins up a framework server node in which Marathon (0.11.1) and Chronos (2.1.0) are running. This means you can build your own Mesos+Marathon+Chronos+Docker PaaS with vagrant up --provider=aws! Marathon works as distributed init.d and Chronos works as distributed cron!

To deploy Docker containers, refer to the Marathon documentation and look at the examples included in this repo.

The mesos installation is powered by Mesos chef cookbook. Please see everpeace/cookbook-mesos.

Base boxes used in Vagrantfiles are Mesos pre-installed boxes, everpeace/mesos shared on Vagrant Cloud.

Prerequisites

Mesos Standalone on EC2

  1. Set ec2 credentials and some configurations defined in standalone/aws_config.yml. You have to fill up EDIT_HERE parts. 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
    
  2. You can now spin up the Mesos box on ec2 with the following commands:

     cd standalone
     vagrant up --provider=aws
    

    After Vagrant has done it's thing, you can see the services running at:

    • Mesos web UI on: http://#_public_dns_of_the_VM_#:5050
    • Marathon web UI on: http://#_public_dns_of_the_VM_#:8080
    • Chronos web UI on: http://#_public_dns_of_the_VM_#:8081

    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 Cluster on EC2

Cluster Configuration

Cluster configuration is defined at multinodes/cluster.yml. You need to edit the file to configure cluster settings and also add in you AWS credentials as outlined in the next section.

# Mesos cluster configurations
mesos_version: 0.23.0

# The numbers of servers
##############################
zk_n: 1          # hostname will be zk1, zk2, …
master_n: 1      # hostname will be master1,master2,…
slave_n : 1      # hostname will be slave1,slave2,…

# Memory and Cpus setting(only for virtualbox)
##########################################
zk_mem     : 256
zk_cpus    : 1
master_mem : 256
master_cpus: 1
slave_mem  : 512
slave_cpus : 2

# private ip bases
# When ec2, this should be matched with
# private addresses defined by subnet_id below.
################################################
zk_ipbase    : "172.31.0."
master_ipbase: "172.31.1."
slave_ipbase : "172.31.2."

Because we assign private IP addreses to VM instances, this Vagrantfile requires Amazon VPC (you'll have to set subnet_id and security grooups both of which associates to the same VPC instance).

Note: Using default VPC is highly recommended. If you used non-default VPC, you should make sure to activate "DNS resolution" and "DNS hostname" feature in the VPC.

You have to configure some additional stuffs in multinodes/cluster.yml which are 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).

# EC2 Configurations
# please choose one region 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"]
# NOTE: 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).
#       In EC2, the limit default is 5.
########################
access_key_id:  EDIT_HERE
secret_access_key: EDIT_HERE
default_vpc: true                  # default vpc or not.

Launch Cluster

This takes several minutes (10 to 30 min.). Go grab some coffee :)

$ cd multinodes
$ vagrant up --provider=aws --no-parallel

NOTE: --no-parallel is highly recommended because vagrant-berkshelf plugin is prone to failure in parallel provisioning.

After instances are all up, if everything went well you can now connect to the

  • Mesos web UI on: http://#_public_dns_of_the_master_N_#:5050
  • Marathon web UI on: http://#_public_dns_of_marathon_#:8080
  • Chronos web UI on: http://#_public_dns_of_chronos#:8081

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

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 VMs 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/

# spin up marathon
$ vagrant up --provider=aws marathon

Stop your Cluster

$ cd multinodes
$ vagrant halt

Resume your Cluster

$ cd multinodes
$ vagrant reload --provision

Destroy your Cluster

This operations terminates all VMs instances forming the cluster.

$ cd multinodes
$ vagrant destroy
