.dockerignore file not respected on MacOS X (VMware)

[Anthony Mittaz]

First of all thank you for this project, I couldn't have mad this this far without out.

It seems that my .dockeringore file does nothing.

If I run the following command:

docker build -t dynamite .
docker run -it -v C:$(pwd):C:/src -p 8181:8181 dynamite

and I have a local node_modules folder I'll always end up with that folder inside my container.
Is there something special I should be doing instead ?

    Directory: C:\src
Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d-----         6/6/2021   4:35 PM                node_modules

I did setup my windows docker machine with VMware.

Dockerfile:

.dockerignore:

node_modules

Hi @sync , Thank you 😊

The .dockerignore is only used at build time to ignore files and folders in the COPY instruction of a Dockerfile.
Your Dockerfile does not use this.
When you bind mount a folder with -v C:$(pwd):C:/src into a running container there isn‘t such filter.

wow I had no idea, thanks for the reply and I guess I can close this issue now.
