- 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 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.
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.
I can't thank you hard enough for such a video!
So nice explanations. Dummies even can understand. Thanks for videos Nana!
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.
great Nana, very instructif, very intuitif video, you are AWESOME. Thanks Nana
Great, Got clear picture of the development workflow. Thanks 👍👍
That was great. Thank you for this useful education
Thanks Ali!
Like your way of explaining things. Thanks a ton
You're welcome Bala. This is much appreciated. 🙂
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
Great job 👍
thanks mam for this great content
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?
I loved it sm
good explanation madam.
can we push a complete container to a virtual machine in another environment? like a VM running in a DigitalOcean environment.
great!
Thanks 🙂
Can we update docker container memory and CPU in online, while container is running?
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 it fires right up.
You have to make sure that the node container configuration in docker-compose file is the same as the configuration you used to create the docker container with docker run command. So for example if you do docker ps -a, you can check the env variables, ports etc of the and compare it to what you have defined in docker-compose. Let me know what you find out!
mommy ? thank you sooo much .😊
before learning docker any prerequisite is necessary?
I would say, basic knowledge of command line and some programming knowledge will help in understanding it better.
At the end i realized, author is beautiful :-)
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?
Hi, Ali. So you can configure 2 build pipelines or 1 multi-branch pipeline for develop and master branches separately. And for each branch you can specify the pipelines steps, which can include building a docker image, pushing it to repo and deploying it to the respective server (dev or prod).
However in most of my projects, where I have configured multi-branch (develop, master and feature branches) pipelines, the only one building docker images will be the develop branch pipeline, which would also deploy the image on a dev server. Then once tested and accepted, that image will be promoted, meaning copied, to the next stage, like integration server and finally to a prod server.
Does this answer help you?
@@TechWorldwithNana Thank you, Nana. yes, it was clear but I don't understand where is the Jenkins position in this scenario? I can config it on gitlab and make images with docker. I can have 2 different servers and handle them in the swarm. where is Jenkins exactly?
Well Jenkins is an alternative to Gitlab CI/CD.
So in this case, you would have just a git repository on Gitlab which will be connected to Jenkins, where the builds get executed for example, whenever a commit is made.
@@TechWorldwithNana Thank you so much. your educations are applicable. give us more details and more educations. I am waiting for more education :)
Thank you Ali, I try my best to speed up with the video production :)
Where exactly is the application deployed anywhere?
@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.
why do you want to push docker compose file to docker hub?
@@prasadhonrao Actually I was confused at that time...but later I used kubernets instead of docker swam and my problem was resolved..

I want to learn the project launching with more detail. many branches and deploying on gitlab and Jenkins. these issues are so prevalent and so many people are searching about them,
you can give us more examples. these subjects are so popular between developers and they wanna learn them
Yes that's right, thanks for your input. I plan to make videos covering specifically CI/CD setup and configuration. 👩🏽🏫
and uh, where is the k8s tutorial??
K8s videos will come soon as well. Work in Progress! :)
