Setting up Hasura/local development

By
In week 2, last task was to set up Hasura platform on my local machine.

Hasura uses docker based deployment of apps on its server. Kubernaties is the tool to manage docker container of custom application on the virtual machines.
The requirement of hasura platform on our local machine is because of our local environment and production environment should be same so that there shouldn’t be any problem when we deploy our application on the remote servers, all things are tested first on the local hasura platform.
On the hasura platform, each application deployed as docker image, which contains separate virtual machine so that no other process can conflict with the processes of the application. Application packed in docker containers so that its resources are limited and it won’t affect the whole giant server. The thing we need to install was the platform and sync the basic docker image, which contains configurations and other required things to make the platform work for us.

Pre-requisites:

First thing was to install VirtualBox and for that we need a system with atleast 4GB RAM and 64 bit Linux OS installed on it. As I told in my previous blog, my system have the recommended configurations.

Why VirtualBox

VirtualBox is a general-purpose full virtualizer for x86 hardware, targeted at server, desktop and embedded use. We can run various operating system in a system by creating virtual machines. The need of VirtualBox tool is for creating and managing the virtual machines during the development of our application.
The next thing was hasuractl developed by hasura itself, which contains all the commands that are necessary for installation of platform.
After that, install kubectl , which is a tool of kubernaties.
I followed instruction and links for the required tools mentioned on local-development repository of hasura on Github.

Starting Hasura

Login to hasuractl using the credentials of beta.hasura.io


Start the local server with command hasuractl local start
Please note that it will roughly download 1 - 1.5 GB docker image from internet.


It may take a long time to finish depending on the speed of your internet connection.
The command exits by pointing you to a url to login to the console.


You can check the pods using command kubectl -n hasura get pods .


If any error occurs such as EOF error, press ctrl+c and use the command hasuractl local clean and then hasuractl local stop . Wait for 2 minutes and start again. It clean the local machine but not delete the downloaded files.
If you want to delete the local virtual machine, use the command hasuractl local delete.


When all thing done, finally you can login to the console.


Now we have our local platform well set, we can continue our project.

What's Next?

Next post is about task in 3rd week, which was Data Modelling for my app White Board.

Idea for an app | First step to internship

It all started when I joined IMAD (Introduction to Modern Application Developement), an MOOC provided by NPTEL in association with Hasura. I completed the assignments and appeared in the final test, scoring an overall of 84%, which, much to my delight, landed me an internship with Hasura. First week task The task in the first week was to come up with an idea for an app that can be demonstrated and used as a Minimum Viable Product (MVP) with just 3 screens. I discussed this task with a few of my friends and researched the internet for viable ideas. After long sessions of discussion and surfing the internet, I finally settled on the idea for an app for a  Collaborative   White Board . The idea   The idea of the app is pretty simple, to create an online platform for collaborative brainstorming by a group/team of people from across the globe. This sort of brainstorming is usually required for startup ideas, projects or the onset of any form of development in a group.

Playing with the Octo-Cat

After I done with setting-up dev environment, next task of Hasura Internship was to learn git basics. https://octodex.github.com/images/dojocat.jpg Git is not a programming language or an IDE About Git Git is the most commonly used  distributed version control system . Git is a mature, actively maintained open source project originally developed in 2005 by Linus Torvalds, the famous creator of the Linux operating system kernel.  GitHub  is a company that provides a platform to do version controlling Git allows a team of people to work together, all using the same files. And it helps the team cope with the confusion that tends to happen when multiple people are editing the same files. Version control in simple terms is nothing but making flags/check points as significant changes are made to your code/work so that you can always go back to whichever version was last working properly or whichever version you want to use at the moment. Why Git and Github? Version contr
