 # mesos-deployment
-Setup Apache Mesos on Cloud Infrastructures using Anisble
+This project setup Apache Mesos master and slave clusters on Cloud Infrastructures using Anisble
+
+
+## Configurations
+
+To run this ansible script you must have at least 4 instances. 3 instances to setup Mesos master , marathon and zookeeper clusters. Along with Mesos master we install marathon and zookeeper. Another one or more instance/s to setup mesos agent/s. You can use ec2 ansible role provided with this playbook to spin up aws instances. To do that you need to set valid aws credentials.
+
+1. set valid aws credentials in `roles/ec2/vars/aws-credential.yml` if it doesn't work add folowing to ec2 task in `roles/ec2/tasks/main.yml`
+
+  `aws_access_key: <your_valid_access_key>`
+
+  `aws_secret_key: <your_valid_secret_key?`
+
+2. Set ec2 instance names under ec2 task `with_items:` configurations
+
+  After you set valid aws credentials and instance names run following ansible playbook command to spin up require aws ec2 instances.
+
+  `ansible-palybook -i hosts site.yml -t "ec2"`
+
+3.  You need to know public ips of all the nodes and private ips of all mesos-master nodes.  List all mesos master public ips under `[mesos-master]` section in `hosts` file. List all mesos-slave *(mesos-agent)* public ips under `[mesos-slave]` section.  You need to set `my_id` hosts variable along with mesos-master ip addresses. This will use to set zookeeper id.
+
+ > [mesos-master]
+
+ > *1.2.3.4 my_id=1*
+
+ > *11.22.33.44 my_id=2*
+
+ > ...
+
+ > [mesos-slave]
+
+ > *123.123.123.123*
+
+ > ...
+
+4. Use mesos-master private ip addresses to set zookeeper servers properties in `roles/zookeeper/vars/main.yml`
+
+  > zookeeper_servers:
+
+  >  \- {id: "1", ip: "172.31.24.149"}
+
+  >  \- {id: "2", ip: "172.31.19.49"}
+
+  >  \- {id: "3", ip: "172.31.25.80"}
+
+5. Set Mesos-master zookeeper quorum value in `group_vars/all.yml` file
+
+  > zk_quorum: 2
+
+6. Now we are set to deploy Apache Mesos cluster (Mesos-master, marthon, zookeeper, mesos-slave). Following ansible playbook command respectively setup mesos-master cluster , Mesos-slaves, and both mesos-master cluster and mesos-slave
+
+  `ansible-playbook -i hosts site.yml  -t "mesos-master"`
+
+  `ansible-playbook -i hosts site.yml  -t "mesos-slave"`
+
+  `ansible-playbook -i hosts site.yml  -t "mesos"`
+
+  If everything works without any error, now you have running mesos cluster on aws instances.
+
+## verifying installation
+
+1.  If your plays works without any error. Now you can access Mesos master console using `http://<master-ip>:5050` run following in one of Mesos master node to find which instance is the leader of cluster.
+
+  ``mesos-resolve `cat /etc/mesos/zk` `` this will return master-ip. Then use it to access console
+
+2. To access marathon console use `http://<master-ip>:8080`
+
+3. If you want run simple task on mesos. run following command on one of master node.
+
+  ``MASTER=$(mesos-resolve `cat /etc/mesos/zk`)``
+
+  `mesos-execute --master=$MASTER --name="cluster-test" --command="sleep 5"`
+
+
+
+## Ansible roles
+- java - install oracle java 8
+- zookeeper - install zookeeper
+- mesos-master - install mesos mastera and marathon
+- mesos-slave  - install mesos slave
