The Forth Report Of My Challenge | Answered Two Questions
2 more questions are covered now.
After the release of the second report, I got many answers. Now It's time for the third report in which I am going to answer 2 more questions.
I recorded a video about the same topic also that you can watch and it will help you better understand it.
The first question is:
What is Kubernetes Batch Job?
A job creates one or more Pods and will keep retrying their execution until a certain number of them have been completed successfully. The Job keeps track of successful pod completions as they happen.
The task (i.e. Job) is completed when a certain number of successful completions is reached. When you delete a Job, the Pods will be deleted as well. Suspending a Job causes all active Pods to be deleted until the Job is resumed.
To run one Pod to completion, create one Job object. If the first Pod fails or is deleted, the Job object creates a new one.
The second question is:
What is TCP dump and how it is helpful in Kubernetes?
If you have applications running as containers in Kubernetes clusters, you may come across scenarios where you want to monitor or analyze raw network traffic.
This is usually needed if your containers are finding random connection issues with your API calls.
But If you are using public cloud providers such as Azure, there are monitoring tools such as Network watcher which can be used to monitor traffic.
But here I am going to talk about tcpdump.
TCP Dump
It is a packet sniffing and packet analyzing tool for a System Administrator to troubleshoot connectivity issues in Linux. It is used to capture, filter, and analyze network traffic such as TCP/IP packets going through your system.
It is used as a security tool as well. It saves the captured information in a pcap file, these pcap files can then be opened through Wireshark or through the command tool itself.

The next step is to solve two more questions that I have added here. You can check them out.
