Dockerfile
# First, specify the base Docker image. You can read more about# the available images at https://sdk.apify.com/docs/guides/docker-images# You can also use any other image from Docker Hub.FROM apify/actor-node:16
# Second, copy just package.json and package-lock.json since those are the only# files that affect "npm install" in the next step, to speed up the build.COPY package*.json ./
# Install NPM packages, skip optional and development dependencies to# keep the image small. Avoid logging too much and print the dependency# tree for debuggingRUN npm --quiet set progress=false \ && npm install --only=prod --no-optional \ && echo "Installed NPM packages:" \ && (npm list || true) \ && echo "Node.js version:" \ && node --version \ && echo "NPM version:" \ && npm --version
# Next, copy the remaining files and directories with the source code.# Since we do this after NPM install, quick build will be really fast# for most source file changes.COPY . ./
# Optionally, specify how to launch the source code of your actor.# By default, Apify's base Docker images define the CMD instruction# that runs the Node.js source code using the command specified# in the "scripts.start" section of the package.json file.# In short, the instruction looks something like this:## CMD npm startmain.js
