It is what it is. I thought docker is one complex course after watching a 5 hours video. It was nice till I ran into Net Ninja, your tutorials are just spectacular

I was searching for docker volumes today. Thanks Shaun!

@PrakashBesra 11 ай бұрын

The second -v flag (-v /app/node_modules) mounts a volume (Docker internal volume) at the /app/node_modules directory inside the container. This is done to avoid overwriting the node_modules directory with the local version. Mounting a volume here means that the local node_modules directory will not be used, and the image's built-in node_modules will be preserved.

So this has been bordering me for a while. What do you do when you want to install packages or uninstall packages as you develop you application. If the node_modules on you host is not in sync with the one in the container?

Are there any pros/cons of implementing the "nodemon app.js" command as a script in the package.json file versus specifying it directly in the CMD instruction of the Dockerfile, or is it more a matter of style or preference?

I got error when I use -v, showed syntax error. I put the path after -v in double quotes, then fix the error. Hopefully can help some of you. And we can delete node_modules from our app as well. Docker use the modules inside image

Does dockerignore file is ignore when we are using volumes? For example if we have placed a folder in dockerignore file but it has been mapped using volumes. Does the folder will be mapped or since it is in dockerignore it will be ignore because it was not copied to the during the image build?

@huzaifajaliawala1904 2 жыл бұрын

If everything is mirrored to the container using volumes so does it meant that dockerignore which avoids some folders to be copied to the image so that folders are now also the inside the container?

@Keitaro51 2 ай бұрын

With volume and all our local files mapped with container /app directory, is "COPY . ." layer still necessary ? Thanks in advance

when you write the sevond volume "-v /app/node_modules" and explained that this creates some folder in our host and maps to it for next runs(16:25). BUT you also use "--rm" which deletes the container after stop, so how can it run the second time as well if after stop its deleted? and what happened with the folder in our host after stop?

I run into an error : "Unable to find image :locally' because there were whitespace in my absolute path after -v tag. So to remove this error, make sure there is no space in folder name in your absolute path. It will fix the problem. hope it helps and the tutorial is awesome!!!

I tried removing the "node_modules" folder in the directory, and not creating a volume for it. But, when the container is created and started, the app crashes... showing the error "Error: Cannot find module 'express''"... Is it still necessary use "-v /app/node_modules" even when we do not have the node_modules folder in our host directory? Why?

Nodemon has an issue, when a crash will happen then nodemon will still continue and not stop. This is why i believe nodemon shouldn't be used here in docker
