 In this blog, we are going to  Set up Python Interpreter and running Python Code on Docker Container: Step 1 : Install docker-ce on Linux OS :  Step2 : Run a container of image - centos:latest.  Step4 : Install python on that container :  Step 4 : Run python commands : We successfully  Set up Python Interpreter and run Python Code on Docker Container: Hope you liked my blog :)

 PROBLEM :   We all know that ansible is famous for it's  idempotency .  But if we configure some service and if we change anything in it's configuration file, then we need to restart that service.  The problem is : if configuration file is unchanged, then? Then also our ansible task will run and restart service unnecessarily. In this case, ansible is not working as idempotent. Our service will restart every time we run the playbook, even if configuration file is not updated. SOLUTION : HANDLERS We can use Handlers in Ansible to tackle this problem.  Handlers are just like a normal task. Handlers will perform an action when listens for a notify event. If nothing notifies a handler, it will not run. Regardless of how many tasks notify a handler, it will run only once, after all of the tasks completed in a particular play. To know more about ansible and it's playbook, check my this blog :  ANSIBLE : How Industries are solving Challenges using Ans...

What is Docker? Docker is an open source containerization platform. Docker enables developers to package applications into containers—standardized executable components that combine application source code with all the operating system (OS) libraries and dependencies required to run the code in any environment . While developers can create containers without Docker, Docker makes it easier, simpler, and safer to build, deploy, and manage containers. It’s essentially a toolkit that enables developers to build, deploy, run, update, and stop containers using simple commands and work-saving automation. What are Containers? The main goal of software development is to keep applications isolated from one another on the same host or cluster. This is difficult to achieve, thanks to the libraries, packages, and other software components needed for them to run. One solution to this problem is containers , which keep the application execution environments isolated from one another but sha...

  Welcome to my menu program This program contains fully automated technologies that can be run directly in any flavor of linux operating system This menu program contains some great technologies like : 1. Amazon Web Services (AWS) 2. Big Data Hadoop 3. LVM partition technique 4. Web Server 5. Yum  6. Docker This menu-driven program is built in python that can be useful in automation of above mentioned technologies. 1. Amazon Web Services (AWS) Using this menu program, you can do following things : - AWS key pairs      - Describe key pair     - create key pair     - Delete key pair - EC2 instance     - Create Instance     - Describe Instance     - Start Instance     - Stop Instance     - Reboot Instance     - Terminate Instance - Create AWS security group - EBS volume     - Create EBS volume     - Attach EBS volume     - Detach EBS volume     ...
