35. DevOps:How do you plan an IAC [Infrastructure As Code] ?


When you are working for DevOps practices, the following question I would like to ask…

How do you plan an IAC [Infrastructure As Code] ?

You or your team member might be expert in Configuration tools.

But without having clear environment specifications these tools will not have any AI to get your environment.

When we do IAC as part of Devops practices, we also need to do identification of Infrastructure needs for different environments.

At that time one need to do the following activities also.

This is not only for a Cloud Architect, even for a DevOps practitioners it is mandatory.

Look into the discussion video mentioned in the below URL.

Please note unless you give specifications to DevOps Engineer he/she can not build sustainable environment.

Your prior planning is very essential.

Cloud architect: How to build your Infrastructure planning practice ?


36. DevOps:Why the DevOps practice team is required to involve in Infra cloud planning? ?

Build Cloud architects-FB promotion

Why the DevOps practice team is required to involve in Infra cloud planning?

I was talking to some clients recently on the importance of Cloud migration activities planning. I have come with some guidelines for them as part of my engagement. Some of my guidelines given to them, I would like to share as below.

When the DevOps practice team need to do the infra setup  for a cloud migration they also need to participate on the identification of Infra activities and the specifications. Which is very essential.

This need to be done as initial step with any Cloud services migration.

As per my opinion we can work with any cloud services like; AWS/AZURE/Google Cloud, etc., by having the above activity as mandatory.

The attached blog/Video contains the same discussion with the details of the steps required to setup a Virtual Private Cloud. The VPC nomenclature we might have seen with AWS. But similar setup or name cane be there with other Cloud service providers also.

Once this VPC is created the systems are going to be hosted on Cloud.

The Ops team’s responsibility is; to make sure the Cloud migration is correctly and completely done for all the live setup.

At the same time they also need to conduct a pilot testing activity successfully which is mandated as per the Agile Projects management [Agile PM] standards before they announce go live.

They also need to do a parallel run along with the past production setup with a new cloud setup for few weeks.

Below URL contains the initial planning discussion as mentioned:

34. DevOps:How to Install Gradle on Ubuntu 18.04 ? [Video]

Gradle logo

How to Install Gradle on Ubuntu 18.04 ? :

Through this blog it is demonstrated the Gradle 4.10.2! installation on Ubuntu 18.04 VM.

At the end of this blog the Installation video clip is attached.


Step#1: Install OpenJDK:

Gradle needs Java JDK or JRE version 7 or
above to be installed.
We will install OpenJDK 8 as below.
Let us update the linux package index.

sudo apt update

Install the OpenJDK package with the below command:

Install the OpenJDK package.

sudo apt install openjdk-8-jdk
Check the java version.

Java -version

Step#2: Download Gradle

Using the below command; Used the below valid command…..

wget -P /tmp
Once the download is completed, we need to extract the zip file into folder; /opt/gradle :

sudo unzip -d /opt/gradle /tmp/gradle-*.zip

let us Verify that the Gradle files are extracted by listing the /opt/gradle/gradle-4.10.2 directory
ls /opt/gradle/gradle-4.10.2

The typical file list will be:

bin getting-started.html init.d lib LICENSE media NOTICE

Step#3: Setting up environment variables:

Now, we need to configure the PATH environment variable to include the Gradle bin directory.
To do this task; need to open a text editor and create a new file named inside of the folder; /etc/profile.d/

sudo vim /etc/profile.d/

In this shell program [config file] paste the below lines;

export GRADLE_HOME=/opt/gradle/gradle-4.10.2
export PATH=${GRADLE_HOME}/bin:${PATH}

The above script will be initiated at startup.

Now, let us Load the environment variables using the following command;

source /etc/profile.d/

Step#4: Verify the Gradle installation

To validate the installation of Gradle
use the command;

gradle -v

It will display the Gradle version.

So the Gradle is installed successfully.
