NOMAD- WINDOWS SETUP FOR DEPLOYMENT OF MICROSERVICE

Installation and setup NOMAD-Windows Server 

Nomad documentation for Windows Server

Software Requirements-****(same for server & client)
Java, maven, nodejs, python, Nomad.

POC performed on 1 Server & 1 Client (Windows 2016 Server)

Server Side Configuration

1.Install Java, maven, nodejs, docker, Nomad, Consul. set environmental variables.

2.Download and extract Nomad & Consul in C:\drive and set the path in environmental variables.

3.In Nomad Folder create a folder with nomad.d in that need to create server.hcl and client.hcl.

Below are the files content of server.hcl and client.hcl.

server.hcl

# /etc/nomad.d/server.hcl

data_dir tends to be environment specific.

data_dir = "C:\nomad\data"

server {

enabled = true

bootstrap_expect = 3

}

---

client.hcl

log_level = "DEBUG"
data_dir = "c:\nomad\data"
name = "testnomadclient_1"

client {
enabled = true

server_join {
retry_join = ["172.16.10.1"]
retry_max = 3
retry_interval = "15s"
}
}

ports {
http = 5656
}

---

Steps to be performed after software installation on Nomad server:

sc.exe create "Nomad-Oasis" binPath="C:\Nomad\nomad.exe agent -dev -bind 0.0.0.0 -log-level "INFO" start= auto

C:\Tools\consul>start-consul.bat

Start--> ZOOKEEPER & KAFKA (Based on the zookeeper & Kafka Directory )

C:\Tools\kafka_2.11-1.1.0\bin\windows\zookeeper-server-start.bat C:\Tools\kafka_2.11-1.1.0\config\zookeeper.properties

C:\Tools\kafka_2.11-1.1.0\bin\windows\kafka-server-start.bat C:\Tools\kafka_2.11-1.1.0\config\server0.properties

Steps to be performed after software installation on Nomad Client:

Run Below Command from C:\Nomad (Location) to add node to the cluster.

nomad agent -config=c:\nomad\nomad.d\client.hcl

Run Zookeeper & KAFKA & Consul On Node

Consul:

C:\Tools\consul>start-consul.bat

Command inside .bat File

consul agent -dev -ui -client 0.0.0.0 -log-level warn -data-dir=/tmp/consul

Zookeeper:

C:\Tools\kafka_2.11-1.1.0\bin\windows\zookeeper-server-start.bat C:\Tools\kafka_2.11-1.1.0\config\zookeeper.properties

Kafka:

C:\Tools\kafka_2.11-1.1.0\bin\windows\kafka-server-start.bat C:\Tools\kafka_2.11-1.1.0\config\server0.properties

NOMAD-UI DASHBOARD

Microservice Deployment

Consul deployment

Download consul &
Download kafka and save it in C:\Drive and set the path in Environment variable.

COMMAND
C:\Tools\consul\start-consul.bat

Kafka - Zookeeper Deployment

Download kafka and save C:\Drive and set the path in Environment variable
Start--> ZOOKEEPER & KAFKA (Based on the zookeeper & Kafka Directory )

COMMAND

C:\Tools\kafka_2.11-1.1.0\bin\windows\zookeeper-server-start.bat C:\Tools\kafka_2.11-1.1.0\config\zookeeper.properties

C:\Tools\kafka_2.11-1.1.0\bin\windows\kafka-server-start.bat C:\Tools\kafka_2.11-1.1.0\config\server0.properties

Microservices-deployment

STEPS TO DEPLOY SERVICES

Nomad JOB Deployment.

C:\Nomad(All Nomad Job files Stored )

microservice1.nomad,

microservice2.nomad,

microservice3.nomad,

microservice4.nomad,

microservice5.nomad,

microservice6.nomad

newconsul.nomad (consul configured as nomad job)

zoojob.nomad (Zookeeper configured as nomad Job)

kafkajob.nomad (Kafka Configured as nomad job)

Open CMD.and cd c:\nomad and to run a job following commands

Nomad job run microservice1.nomad

Nomad server members (to see list of servers(leader))

Nomad node list (to see list of nomad clients)

Pods are called as Allocations in NOMAD.
