Deploying the containerized application with Docker Compose || Docker Tutorial 12

How to deploy your containerized application with Docker Compose.

In this video I show how to deploy an application, which we built before in a docker image. So, after you package your application in a docker image and save it in a private repository you need to deploy it on some server. In this video I use docker compose to deploy the application.

This is the last video of the "Docker in Practice" video series:

You can check out my videos for the Pre-Requisites:

For any questions/issues/feedback, please leave me a comment and I will get back to you as soon as possible.

This video is the 12th of a complete series for beginners, where I explain the basic concepts and also show you demo's like deploying your containerized application. At the end of this tutorial you will fully understand Docker and Kubernetes.

Hi Nana,
This is Mr.B from India. I'm watching your video course Docker and Kubernetes beginners from the start. Your way of teaching very good and you going slowly. So, I can able to understand easily. Please include more in-depth knowledge about Kubernetes, Jenkins, customization, and real-time scenarios which helps me to day-to-day work in my company. Also, please include real-time troubleshooting and problem-solving issues. This helps a person like me who started a beginner as a DevOps Engineer.

You are running that container on localhost. That's what I could see in the URL. I thought the video showed how to upload it to a real production environment.

[nuranamirzaghayeva]

So nice explanations. Dummies even can understand. Thanks for videos Nana!

[balasubramaniam]

Like your way of explaining things. Thanks a ton

[yummywithali]

That was great. Thank you for this useful education

[mathewkargarzadeh]

Great video Nana !! Appreciated. I wish you do one docker- compose with app/db dependency and wait time, and with Volume Mount. Thanks again for sharing your knowledge. Mat.

[FathyTekitek]

great Nana, very instructif, very intuitif video, you are AWESOME. Thanks Nana

[nadunsamarasinghe]

Great, Got clear picture of the development workflow. Thanks 👍👍

[murad_albarki]

I can't thank you hard enough for such a video!

[marctowersap]

weird, I have mine in an azure container registry instead of AWS. after running docker-compose up, the two mongo containers started fine, but the node container fails over db login issues. but if I just docker start <containerid> it fires right up.

[bhaidar]

Hi Nana, great video as usual. Have you done any tutorial on using Jenkins to create a docker image and push it to AWS? Thanks

[Han-veuh]

At 8:08 you mention don't need to use the localhost:port in app because the hostname and port number are already defined in the docker-compose under the service name. However, i can't see where is the hostname defined in the docker-compose?
I do see the ports defined as 27017:27017 though. Just to confirm, the code in node app is connecting to the 27017 on the right, not left side of the colon right, which is the port of the mongodb in the container?

[thevijayraj]

At the end i realized, author is beautiful :-)

[HindiTechClub]

can we push a complete container to a virtual machine in another environment? like a VM running in a DigitalOcean environment.

[srujanareddy]

Can we update docker container memory and CPU in online, while container is running?

[niant]

@nana
one question --> How to push docker compose file to docker hub.

Any one can help me? It would be great help for me. Thanks in advance.

[dhanwadc]

before learning docker any prerequisite is necessary?

[SK-ybbx]

Where exactly is the application deployed anywhere?

[yummywithali]

I have a scenario Nana. I have 2 branches in gitlab. development and master. development is the develop environment and I want to run it at a subdomain of my project. ex. develop.example.com.
i want to run all of these on docker and with CD/CD in gitlab. How can I integrate this scenarion in my project?
How can I say docker or jenkins to build for example develop and master seperately?
