How do I get nodemon to work with Next.js in a container?

I’m at the beginning stages of learning to use docker as my development environment. I want to use NextJs and nodemon so I don’t have to keep restarting a container to see the changes.
My Dockerfile:

# syntax=docker/dockerfile:1
FROM node:18-alpine
WORKDIR /usr/src/app
COPY . .
RUN npm install --production
RUN npm run build
CMD ["npm", "start"]

My package.json:

{
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start"
  },
  "dependencies": {
    "next": "latest",
    "react": "^18.2.0",
    "react-dom": "^18.2.0"
  },
  "devDependencies": {
    "nodemon": "^2.0.20"
  }
}

Shows to run the following:

 docker run -dp 3000:3000 `
    -w /app --mount type=bind,src="$(pwd)",target=/app `
    node:18-alpine `
    sh -c "yarn install && yarn run dev"

How do I configure this set up so I can make changes and see the changes straight away?

I’ve changed package.json to

"scripts": {
    "dev": "nodemon next dev",
    "build": "next build",
    "start": "next start"
  },

Looking in the container logs I’m getting the following message:

2023-02-04 10:08:47 error - Invalid project directory provided, no such directory: /app/next

How do I correct the directory?
