Developing with Docker - Docker in Practice || Docker Tutorial 8

Once you've learnt the basic concepts, it's important to see how Docker is actually used in practice or in real world development so to say.
In this video I show you how to work with Docker containers when developing applications. So, this will be a demo of developing a simple UI with JavaScript and Nodejs in the backend and connecting it with a Docker Container with a Mongodb database

Greetings from Serbia. Thank your for this course. It has simple and very clear explanations for all the concepts (from basic to much more complex) which are sometimes very hard to undestand when we read it from other sources(books, sites et.).

[rajesho]

The good thing about ur tutorial is u always make it in terms of start to end :) it’s makes things complete and satisfy one’s search 😇🥰

[AndyRodriguezJimenez]

It was a litter hard to pass to the next video because of "JS ERROR", after install all of this(git, nodejs, npm), the solution was just install NPM INSTALL EXPRESS and the node server.js start successfully. Great Video thank you.

[mizipizi]

So being totally new to this stuff, i had my problems figuring out that i have to adjust the "server.js" file with an editor like notepad ++ and adjust the lines 18, 26, 29, 25(where var response should be defined !), 48, 51.
I do not know whether it was on purpose to teach me how to figure out myself or by accident either way, Thank you for your great tutorial! managed to get it working.
PS: Thank you so much :) you really are doing great !!

[godwineffiong]

Thank you so much Nana for putting up this wonderful video. i am a novice with JS. I just need a little clarification form anyone who understands JS and have tried out this video.

After downloading this souce code, and running all the necessary npm install and node server.js ...am i supposed to get a black screen on the browser page despite seeing "app listening on port 3000!" on my terminal?

on checking the style written on the html page, i saw
#container {
display: none;
}
does it mean the content of the index.html should'nt be displayed?

[atendimentosuperdivulga]

Great video, helped me a lot! Following your info I managed to create my own docker + react environment, thanks!

[himanshujain]

First of all Thanks. Just one question have you run node part within same docker network or, or have you run node part in localhost and node automatically connected to mongo?
Thanks

[shankureddy]

Hi Nana I appreciate you for sharing your knowledge with us, Great job! Coming to the point it would be helpful for us if you can make a video on how to run the JS application . Thank you,

[SuvanshGupta-or]

Hi, Can anyone tell when I am running this web app on my ide(VS Code) by copying the code in index.html file, server.js file, package.json file, and package-lock.json file and creating these files why I am not able to run the web app on my localhost.There is no error but the screen is blank

[garyboriskin]

The stand alone nodejs UI can access the mongodb. When creating nodejs container from my-app image the container starts with 'app listening on port 3000!' terminal message. But localhost:3000 display empty page. Nothing is displayed in logs.

[silentcicada]

Hey, thanks for the video! The tutorials are just amazing! Can you tell the customizations you have in your terminal?

[dhanunjayreddy]

Hi, Could you please do a video on how to bring communication on containers running on multiple hosts?

[rktestingtools]
