(Q.1) What is Apache Kafka?

Apache Kafka is a publish-subscribe open source message broker application. This messaging application was coded in “Scala”. Basically, this project was started by the Apache software. Kafka’s design pattern is mainly based on the transactional logs design. For detailed understanding of Kafka, go through,
Kafka Tutorial.

(Q.2) Enlist the several components in Kafka.

The most important elements of Kafka are:

Topic – Kafka Topic is the bunch or a collection of messages.
Producer – In Kafka, Producers issue communications as well as publishes messages to a Kafka topic.
Consumer – Kafka Consumers subscribes to a topic(s) and also reads and processes messages from the topic(s).

Password-store keeps your passwords (or any other sensitive information) saved in GnuPG encrypted files organized in ~/.password-store. For more information about GPG, consult the GNU Privacy Handbook.

Getting started

To get started, install pass and generate a keypair.

$ brew install pass
$ gpg --gen-key
$ gpg --list-keys

Use pre-built gccemacs

Fortunatly we could use pre-built gccemacs right now.

Those two repos did the greate job for us.

Prerequisites

1) GCC with libgccjit enabled

For that you need to compile gcc (duh). I edited Homebrew's gcc formula:

	#!/bin/sh

	if [ -z "$1" ];then
	echo "Usage:"
	echo " proj2ram proj-name"
	echo " proj2ram restore proj-name"
	exit 1
	fi

	#!/bin/bash
	set -ex

	usage()
	{
	echo "usage: k8s-jprofiler-attach.sh pod_name"
	}


	k8s_jvm_pod="${1}"

	control 'azurerm_resource_groups' do
	describe azurerm_resource_groups do
	its('names') { should include 'myResourcegroup' }
	end
	end

	control 'azurerm_virtual_machine' do
	describe azurerm_virtual_machine(resource_group: 'MyResourceGroup', name: 'prod-web-01') do
	it { should exist }
	it { should have_monitoring_agent_installed }
	it { should have_only_approved_extensions(['MicrosoftMonitoringAgent']) }
	its('type') { should eq 'Microsoft.Compute/virtualMachines' }
	its('installed_extensions_types') { should include('MicrosoftMonitoringAgent') }
	its('installed_extensions_names') { should include('LogAnalytics') }

	its('properties.location') { should eq 'northeurope'}

	control "subnet" do
	describe azurerm_subnet(resource_group: 'MyResourceGroup', vnet: 'vnet-prod', name: 'subnet-web') do
	it { should exist }
	its('address_prefix') { should eq '192.168.0.0/24' }
	its('nsg') { should eq 'my-nsg'}
	end
	end

	//all job name
	jenkins.model.Jenkins.instance.items.each {
	println "Job: ${it.name}"
	}

	//method list of Jenkins instance
	jenkins.model.Jenkins.instance.class.methods.each {
	println "Jenkins method: ${it.name}"
	}
