True story: Epic Advice From An Amazing Lady

‘Some guys don’t have a social circle’

That’s what my co-worker told me after tossing around the idea of “dating app”

I am 27 and have a nonexistent social circle.

I would describe myself as intuitive, genuine and easygoing. I am a fast learner, an abstract thinker and very resilient to change. I have had others say I’m compassionate, smart and impulsive (which is getting better with age.) When I was younger, my family said that I would be a good philosopher or artist. My mother has been influential in my life since I was a child. She has exposed…

Centralized logging is an essential component of any production-grade infrastructure. Analyzing log data can help in debugging issues with your deployed applications and services, such as determining the reason for service termination or application crash.

Let’s design one POC for a quick setup.

Components

Architecture

Most things that you did manually can be automated!

Goal

My new task is to take a screenshot of Grafana dashboard at some point of time and email that captured screenshot to business users.

What

Grafana — Grafana is the open-source analytics & monitoring solution for every database.

Puppeteer — Puppeteer is a Node library that I used for scraping data.

How

Challenges:

1. Allow ignore-certificate-errors [for invalid/unknown/self signed SSL certificates]

This is actually very exciting stuff explained in the simple 4 step process:

• Login Grafana
• Open the dashboard and wait for Navigation [wait until network idle]
• Take full page screenshot in high-quality jpeg images.
• return appropriate response and close pptr

Sounds cool!

Most things that you did manually can be automated!

Goal

My new task is to capture a screenshot of QlickSense dashboard if data[basically KPI values] is within limits at some point of time and email that captured screenshot to business users.

What

QlickSense — A free data visualization and discovery tool that lets you analyze data quickly and make business decisions fast.

Puppeteer — Puppeteer is a Node library that I used for scraping data.

How

Challenges:

1. Allow ignore-certificate-errors [for invalid/unknown/self signed SSL certificates]
2. Dynamic Scraping [to get all KPI keys(title) and values(data/text) from dashboard]

This is actually very exciting stuff explained in the simple 4 step process:

• Login
• Open dashboard[wait until network idle]
• Start scraping and make JSON
• Take a screenshot and close pptr

Sounds cool!

Untold Friendship with Strangers

we are not friends…
we’ve never invited each other for dinner
or exchanged gifts,
or made plans to catch the first day first shows
we’re not even connected on Facebook,
nor do we make each other laugh on snapchat
we are poles apart…
but in the endeavour, in resolve…
we’re quite alike
strangers in real life…
but when we meet,
there’s an unspoken bond,
a trust that is deeply felt,
and holding hands a new sky opens up.
strangers…

yet closer than friends

Prerequisites

To follow this tutorial, you will need the following:

• One Ubuntu 16.04 server
• An account on Docker Hub ( We’ll publish our first Docker Image to Docker Hub)
• Amazon AWS account (https://aws.amazon.com)

How to install and use docker?

Image building

We are going to build our image.

We are going to use three files:

• A Dockerfile, it describes the way our image must be built,
• An index.php document, our PHP page which displays Hello World.
• Our logo to add some colour to the page.
• Clone — https://github.com/hariom282538/docker-images

Put those files into a directory on your system:

mkdir helloworld && cd helloworld
git clone https://github.com/hariom282538/docker-images.git
cd docker-images/
docker…
