How to get back to shell in nodejs:latest docker image?

Question

I'm newbie to docker, I tried this command

docker run -it node:latest

then, I was in the node REPL,

Welcome to Node.js v16.3.0.
Type ".help" for more information.

I tried control+c ,but this quit the image,

Is there any way to go to the shell in this image?

That container is just running a `node` processes; it doesn't have your application source code or anything else in it. You wouldn't typically "go to the shell" any more than if you were running a `node` REPL in a non-Docker development environment. You might look at Docker's [Sample application](https://docs.docker.com/get-started/02_our_app/) tutorial, which walks through a typical workflow of building and running a custom image, even based on Node. — David Maze, Jun 10 '21 at 17:10

In order to overwrite the entry point of the docker image you're using, you will need to use the --entrypoint flag in the run command.

docker run -it --entrypoint bash node:latest

For better understanding on how to work with already running docker container you can refer to the following question

When I was in the REPL , is there a way to get back to shell? – user956609 Jun 12 '21 at 21:28
this worked for me - note that `node:latest` is the name of the container - so for me my full command was `docker run -it --entrypoint bash foo` – John Bachir Feb 07 '22 at 07:02
