My dockerignore file is not saving anything

Question

I have a .dockerignore file and I want to exclude node module node_modules.

Whatever I type in the file and I save, it does not save.

What could be the issue?

Answer 1

1. Looks like you have to set proper chmod and chown for this file and add it to repository via git commit.
2. Check official docs at https://docs.docker.com/engine/reference/builder/#dockerignore-file

Answer 2

I don't know why it is still not saving through vs code. So finally what I have done is, I have open it in another editor and then I was able to save it.
