SSH Config and Ansible Host Generator and Why I am doing it this way?
I am recently playing the role as an SRE and that is why I have to deal with a lot of servers. Not only cloud once or clusters but also bare metals as well as Virtual Machines. For more systematic environment preparation, I have Gitlab pipeline. But for basic tasks like change the config on demand or check a specific directory or search something or any other unpredictable or repeated tasks, I need Ansible for better grasp from my local machine or Bastion server. So, what do I have to do?
- Create an entry to the .ssh/config file
- Create an entry ansible host file as inventory
Repeated tasks? For me, yes. I needed to manage these. So, created a python script

Perform rsync asks for password on the remote server before starting the transfer. Sometimes we need to run rsync by crontab where it is not possible to give password. Here is a solution to use crontab to execute rsync without any password.
This is helpful when you are scheduling a cron job for automatic backup using rsync.

Finding an Efficient Solution on Reading and Comparing CSV files
I have always worked with Linux Systems and thus Bash was my go to tool for some specific tasks. But now I am much more aware with Python than Bash as it does give me better grasp on things.

Containerization gives us many benefits from packaging to distribution and others.

Effective use of Redis with Python and Connection Pool

rsync is a free software computer program for Unix and Linux like systems which synchronizes files and directories from one location to another while minimizing data transfer using delta encoding when appropriate. An important feature of rsync not found in most similar programs/protocols is that the mirroring takes place with only one transmission in each direction. This tool is very appropriate to keep backup or setup mirror service. In this article you will get some clear idea.

Perform rsync asks for password on the remote server before starting the transfer. Sometimes we need to run rsync by crontab where it is not possible to give password. Here is a solution to use crontab to execute rsync without any password.
This is helpful when you are scheduling a cron job for automatic backup using rsync.
