Open iTerm window, type the below command to go to downloads directory.
cd downloads


For few Mac laptops, it may add .txt in the end of pem file. in that case you need to remove .txt in the end


pwd
and then execute below commands to make sure you are not making keys publicly viewable. 

chmod 400 *.pem

6. Paste the url from example highlighted above in step # 4.
ssh -i "mykey.pem" ubuntu@dns_name.compute.amazonaws.com
7. type yes when it is asking to connect.
8. now you should be in AWS cloud, screen should show something like this, It means you are successfully connected to EC2 instance running on AWS cloud.

  How to setup SonarQube using Docker compose? SonarQube is static code analyis tool. It is open source and Java based tool. SonarQube can be setup using Docker Compose with less manual steps. What is Docker Compose? Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.  Since Docker Compose lets you configure related containers in a single YAML file, you get the same Infrastructure-as-Code abilities as Kubernetes. But they come in a simpler system that’s more suited to smaller applications that don’t need Kubernetes’ resiliency and scaling.   The purpose of  docker - compose  is to function as  docker  cli but to  issue multiple commands much more quickly. To make use of  docker - compose , you  need  to encode the commands you were running before into a  docker - compose . yml  file   Run  do

Setup build agent/slave VM and Integrate with Jenkins Master

Jenkins has powerful feature of master slave architecture which enables distributed builds. This article we will learn how to establish slave nodes on Ubuntu machines and integrate with Jenkins Master. Jenkins Master Your main Jenkins server is the Master. The Master’s job is to handle: Scheduling build jobs. Dispatching builds to the slaves for the actual execution. Monitor the slaves (possibly taking them online and offline as required). Recording and presenting the build results. A Master instance of Jenkins can also execute build jobs directly. Jenkins Slave A Slave is a Java executable that runs on a remote machine. Following are the characteristics of Jenkins Slaves: It hears requests from the Jenkins Master instance. Slaves can run on a variety of operating systems. The job of a Slave is to do as they are told to, which involves executing build jobs dispatched by the Master. You can configure a project to always run on a particular Slave machine, or a particular type of Slave ma
