This is something about creating a Network Topology setup in such a way that System A can ping to both the systems (system B and system C) but both these systems should not be pinging each other without using any security rule e.g firewall etc.
In the very first step we have to attach all the systems to the Host adapter so that they all will belong to the same Network.
The AWS Command Line Interface (CLI) is for managing your AWS services from a terminal session on your own client, allowing you to control and configure multiple AWS services and implement a level of automation.
With just one tool to download and configure, you can control multiple AWS services from the command line and automate them through scripts.
we need to download AWS CLI Version 2 and then we’ll be ready to use command line interface
you can download it from here:
We have to provide keys to configure because unlike human, machines use keys to login instead of…
Kubernetes’ increased adoption is showcased by a number of leading companies which have integrated the technology into their services.
This one is all about Creating a Network Topology such that we can ping google but not Facebook at the same time.
Firstly …Lets gather some basic info about the current working system.
We can use #ifconfig command to check Ip address and netmask of the current system.
This blog is Something about Configuring Reverse Proxy i.e. Haproxy and updating it’s configuration file automatically on each time new Managed node (Configured With Apache Webserver) join the inventory on AWS.
HAProxy is free, open source software that provides a high availability load balancer and proxy server for TCP and HTTP-based applications that spreads requests across multiple servers. It is written in C and has a reputation for being fast and efficient (in terms of processor and memory usage)
🔹Firstly we have to update the Ip addresses in Inventory file of controller node on which we want to…
We all always heard of Configuring Hadoop manually in a very typical and lengthy way by going to the different nodes separately but have you ever heard of configuring it without going to nodes.
Yes…In this Article we are going to configure it through Ansible tool with complete end to end Automation.
So lets begin ..
Ansible is simple open source IT engine which automates application deployment, intra service orchestration, cloud provisioning and many other IT tools.
Ansible uses playbook to describe automation jobs, and playbook uses very simple language i.e. YAML which is very easy for humans to understand, read and write. Hence the advantage is that even the IT infrastructure support guys can read and understand the playbook and debug if needed (YAML — It is in human readable form).
Ansible is designed for multi-tier deployment. Ansible does not manage one system at time, it models IT infrastructure by describing all of your systems…
Ansible is simple open source IT engine which automates application deployment, intra service orchestration, cloud provisioning and many other IT tools. Ansible is easy to deploy because it does not use any agents or custom security infrastructure.
So firstly we should talk about Idempotent Nature….
Idempotence means after 1 run of a playbook to set things to a desired state, further runs of the same playbook should result in 0 changes.
Why we need to Restart HTTPD services again..?
Its because when we make some changes in Configuration file of Managed node through Ansible playbook , just after that we…
This article is all about the Integration of Docker with Ansible . In this we are going to configure Docker on the Managed node without going manually to that node.
It is a node that runs on any machine which hosts VMs and interact with both OS and hypervisor to maintain the lifecycle of instances running on each of the host nodes.
Note : Ansible is only installed on the Controller Node.
The Remote nodes or the hosts which are managed or controlled by the controller node are known as Managed Nodes.
Docker is a set of platform as a…
Firstly to use Docker we should know what Docker exactly is and Some more things about it like how to install it and most importantly how to use it.
Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels.
And most importantly it has the capability to launch the operating system in just 1 second after the command is been executed.
Now as we…
