Introduction to Kafka

Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.

Terminology:

• Producers send messages to brokers
• Consumers read messages from brokers
• Messages are sent to a topic

• From - https://github.com/Kunena/Kunena-Forum/wiki/Create-a-new-branch-with-git-and-manage-branches

git checkout -b [name_of_your_new_branch]

• Push the branch on github :

git push origin [name_of_your_new_branch]

• When you want to commit something in your branch, be sure to be in your branch.

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

#!/bin/bash

# (optional) You might need to set your PATH variable at the top here
# depending on how you run this script
#PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

# Hosted Zone ID e.g. BJBK35SKMM9OE
ZONEID="enter zone id here"

# The CNAME you want to update e.g. hello.example.com
