A blog site on our Real life experiences with various phases of DevOps starting from VCS, Build & Release, CI/CD, Cloud, Monitoring, Containerization.
In this lock-down, everyone has to maintain a social distance and in this trying time, we can learn from docker to isolate ourselves. So before that, we need to learn how docker does it?
The best approach to learn is to simulate it. For that, we’ll be creating our own container tool for the application to isolate itself.

Preserving Source IP address is an important factor in a live environment because the IP address is one of the things which enables you to do some advanced stuff like:
Security: Security is an important factor which we cannot ignore. With the Source IP you can white list the access to the applications which are behind the internet-facing load balancer.
Imagine you wake up one day, open your front door, and find huge wooden logs of different shapes and sizes placed in your front yard. On one of them is a note that says, “Well, here have ’em, all the logs, both structured and unstructured. Please deliver all the furniture by the end of the week or else … Now, if you’re inexperienced in “woodwork”, you need to start thinking. This is, more or less, how I felt when I was first assigned a task like this.
At the time, I faced a fair amount of difficulties bringing the logs from servers to visualize in kibana. The area which was most troubling and rewarding was figuring out logstash. This blog is a helpful summary of what I learned about logstash and how it helped. So, Ladies, Gentlemen, and others, sit tight and read on.
Distinguishing between defaults and variables is an important design decision when developing an Ansible role. Defaults serve as your public interface, providing suitable values that users can modify according to their needs. Variables, on the other hand, represent your internal framework, containing constants that must remain constant for the role to function effectively.

A key point is this: use default values for values that users can change, and reserve variables for the role’s internal needs.
