JavaScript Integration with Docker & Use cases of JavaScript

In this article, we have created a web application for Docker and we will run all the docker commands

What is JavaScript?

• JavaScript is a scripting language that enables you to create dynamically updating content, control multimedia, animate images, and pretty much everything else. (Okay, not everything, but it is amazing what you can achieve with a few lines of JavaScript code.)

What is Docker?

• Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications.
• By taking advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production.

How to Integrate JavaScript with Docker?

• First, we have to install and start the ‘Docker’ service in our base OS as:

yum install docker

systemctl start docker

systemctl start httpd

• Copy or create HTML code in:- /var/www/html/

/var/www/html/

• Copy or create a CGI file in:- /var/www/cgi-bin/

/var/www/cgi-bin/

Note:- Make sure your python cgi file executable using:- chmod +x <filename.py>

chmod +x test.py

ramitsoni/task-7

• Now we have to start our HTML code in Google Chrome(Windows) using the IP of VM.
• We can execute docker commands on this website:

http://192.168.43.245/index.html

• To check running containers are :-

docker ps

• To launch a container :-

docker run — name=centos centos

• To delete docker container use docker rm <container_name>

docker rm centos

• Check all the list of docker containers docker ps -a

docker ps -a

Now We can perform the different operations of docker like:-

• docker images
• docker run
• docker rm -f
• etc.

Use cases of JavaScript

JavaScript is at the forefront of the programming realm. Out of over 1.6 billion websites on the Internet, JavaScript is used in 95% of them.

Common examples of JavaScript uses and applications include:

1. Presentations
2. Web Development
3. Server Applications
4. Web Applications
5. Games
6. Mobile Applications
7. Create Animation

It is important that you learn how to utilize such a language for the benefit of your own business. Continue reading to learn more about when and where to use JavaScript.

My favorite Industry with JavaScript application development

My favorite apps for Android are Progressive Web Apps like Twitter (written in JavaScript) because they’re light and fast, and I don’t have to wait for them to install to start using them.

Progressive web applications start out just like any other web app, but when a user returns to the app and demonstrates through usage that they’re interested in using the app more regularly, browsers will invite the user to install the app to their home screens. PWA’s can also benefit from push notifications, like native apps.
This is where it gets interesting. Just like any native app, the progressive web app will have its own home screen icon, and when you click on it, the app will launch without the browser chrome. That means no URL bar and no web navigation UI. Just the phone’s usual status bar and your app in all its almost full-screen glory.
This has been a long time coming. None of the technology is particularly new — with the notable exception of the emerging cross-platform standard.

And this is my favorite thing about JavaScript, because that Twitter PWA works on my Android phone, on my iPad, on my desktop browser, and I never have to install it anywhere. On my mobile devices, it looks and acts just like a native app, and even when I’m offline, I can browse tweets already downloaded and cached.

If you want your apps to be usable by most people, JavaScript is a great choice.
