I can see the docker image start then exits immediately. Seems to be happing to others in the comment as well. My Ubuntu install fires up and got completion messages on the other video install steps. ****************FIXED************************ Used docker run -d -it node to get this to run in a container.. -it = interactive terminal??

[@HammadHassan-nd3qd]

if conaitner exit immediately with cotnainer terminal dsiabled then just run "docker run -d -it node" in power shell. it will create a new container with runinng status. delete previous one then.

[@wilraul9695]

thanks for the tip, it worked, do you know why the previous container fails?

[@EnesKab]

[@nadavnesher8641]

Brilliant!

[@manishchandra6889]

for node image latest which linux distro is it going to use?

[@edwingarcia5043]

00:58, as far as I understand Docker, images don't contain an OS, but rather just the "file system" environment of, let's say, a Linux distribution, for example, an Ubuntu version 22.04 parent image might contain the file system of a fresh Ubuntu Installation. The OS of the host machine (the machine where the Docker Engine is installed) is being used. Let's see another example, the image `golang:1.19-alpine` contains file system (the executables, directories, etc) of the Linux distribution **Alpine**, plus a Go v1.19 installation, so that you can execute your Go application. Well, that's how I understand it, now, let's keep watching :D

[@paskuda_sutulaya]

Thanks! I was confused a bit by the statement that "the parent image has the lightweight OS" while the container runs on the host OS, but now everything is clear 👍

[@user-hm8kj8is8q]

perfect as always 👏

[@NetNinja]

Thank you so much 😀

[@azizullah410]

Hey Shaun I have a question. What would be the parent image for MERN App?

[@arkimphiri]

You are the best. Please a Ruby on Rails Course

[@AitHajar_00]

when i try to pull the node image i get this error ' unauthorized: authentication required. '

[@mohamedyoussef8835]

Awesome tutorials ++++++++++++++++++++++++++++ Thank you.

[@user-nr3ye8qd1i]

On what basis do you decide which node image you are going to select for your application ?

[@mohammadruhulamin5991]

you make everything water!

For some reason, the docker image starts then exits immediately. I've been searching for help on this topic but don't know enough about it.

[@markritchie7044]

add the -it option to docker run

[@matthewpaolini]

@@markritchie7044 That worked from command line. How do I get it to work from Docker Desktop like he did?

[@pankajdharmik1306]

@@matthewpaolini got any solution??

[@HoodlumMedia]

OHMYGOD all this time and i can just... drop those commands into any command shell. lol. I was spending ages trying to find out where to open a terminal.

[@rowan7366]

Request courses for docker with kubernetes and skaffold

[@lexyu9693]

why I docker pull node finished then use Dokcer Desktop images node select run, when I click container start then status immediately exited? not running

[@ahahahaha-kf4xe]

no virtualization may be. hard maybe

[@oliversaxon8656]

I get the same - did you figure this out?

[@lexyu9693]

no, but use another official image it works, like nginx or hello-world, I don't have a clue, stuck here.

[@festus-kogo]

I used docker run -d -it node to get this to run in a container

ninjaaaaaaaaaaaa!!!!!!!!!!!!!!!!!!!

[@nithinkamineni9392]

My Docker Containers Exiting immediatly as soon as click run on my NodeJs Image. any fix?

[@tarun3dadlani]

run the image using: docker run -d -it {image_name} I found this solution in the comments section but I am wondering how in the tutorial the image is running using the GUI of the docker but on our machine it is not

[@AlexanderHariri1984]

Is that a british accent?

It most certainly is!
