FROM mcr.microsoft.com/dotnet/sdk:8.0-alpine

# Install Node.js - we use Node.js 20 here, pick another version if you like that
RUN apk update \
    && apk add --no-cache curl \
    && curl -sL https://deb.nodesource.com/setup_20.x \
    && apk add --no-cache nodejs npm build-base

WORKDIR /app

# RUN npm init -y
RUN npm install -g nswag

docker build -t <your tag> .
docker run --rm --volume "${PWD}:/app" generator npx nswag openapi2csclient /input:https://<base_url>/swagger/v1/swagger.json  /classname:GeneratedClient /namespace:Namespace /output:GeneratedClient.cs

After running the docker run command above you should now see a new file called GeneratedClient.cs.
