[@tarcisio_menezes]

Awesome! Subscribed!

[@chaminda512]

Well explained 🤩

[@lvhailon]

I think there should be a space between the -p and the port numbers, is that right? I mean it should be"-p 8000:8000". but why "-p8000:8000" also works?

[@TechWorldwithNana]

Yes both should work, but I usually write with space. I probably overlooked it

[@akashlodhi8021]

Please create some video covering, docker volume

[@ancortrujillodownes6324]

Hi Nana, when you talked about debugging the application using docker exec, are any changes made inside the container terminal permanent? or do they get reset whenever the container is stopped, or when docker run command is used? Also, is there a way to extract specific logs (as in a specific path) from inside the container, without having to enter the terminal? is there a way to also extract any config file from outside the container? Thanks in advance!

[@TechWorldwithNana]

Hi Ancor. These are actually great questions. Yes you can make changes to your container with docker exec and these changes will persist and won't be reset when you stop and start the container again. It will be reset only when you re-create the container. The second question: yes you can copy files out of the docker container from outside without the terminal. You can do this using "docker cp " command. hope this helps!

[@ancortrujillodownes6324]

@@TechWorldwithNana Thank you very much! and keep up the great work ;)

[@Lunolux]

great job

[@acronproject]

Thanks for this

[@marcohdez5045]

Hi, I would like to see a video about how to debug a docker container, regards.

[@ROYALNIL_SITE]

excellent

[@siddharthbarhate7659]

I have two questions what do the -t parameter mean while executing exec command?I tried reading on internet but didn't quite get it. Also, what is the purpose of the detach mode?

[@TechWorldwithNana]

1. -t stands for terminal. So with -it (interactive terminal) option you will get the container's terminal. Without -it you can execute just 1 command in the container from outside, like: "docker exec my-container printenv" 2. detached mode just enables you to run the command in the background, so you can continue using the same terminal session.

[@manikantakumar3645]

Nice tutorial series. One doubt, how can I change the port bindings of an already existing container? You explained how to add port bindings while creating a container. But how to deal with existing containers?

[@shrhawk]

can you kindly share the slides in the video ?

[@jingyuliu1679]

How can I donate so you can keep making these awesome videos?

[@TechWorldwithNana]

Hi Jingyu, I really appreciate that :) I don't take donation, but I started creating paid products. So if you want to support me you can buy e.g. this ebooks bundle bit.ly/3l4qXkR or I also publish my first udemy course in around 2 weeks 😊🙏 All the best!

[@ananthupadhya5195]

When you were naming the docker container you used the image name. What will happen if there are two containers with the same image name? Shouldn't this be container id or old container name specific?

[@gebrekirstosgebrekirstos6878]

Docker for Windows 10 do you have tutoring how we can configured

[@chetanurade5247]

docker start or docker start , does it make any difference with either of the commands, I have observed that with docker start results in generating new container_id... would that make any difference.. Thanks Nana :)

[@mohanbayyana]

what is meaning of docker entrypoint?

[@IndianSumaira]

Nana, where are other videos ??? Docker Tutorial 6 , 7, 8 ???? Please Nana upload others too, I need those please
