# Dockerfile contains instructions how to build a Docker image that# will contain all the code and configuration needed to run your actor.# For a full Dockerfile reference,# see https://docs.docker.com/engine/reference/builder/
# First, specify the base Docker image. Apify provides the following# base images for your convenience:# apify/actor-node-basic (Node.js on Alpine Linux, small and fast)# apify/actor-node-chrome (Node.js + Chrome on Debian)# apify/actor-node-chrome-xvfb (Node.js + Chrome + Xvfb on Debian)# For more information, see https://docs.apify.com/actor/build#base-images# Note that you can use any other image from Docker Hub.FROM apify/actor-node-basic
# Second, copy just package.json since it should be the only file# that affects "npm install" in the next step, to speed up the buildCOPY 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 start1const Apify = require('apify');2const fetch = require('node-fetch');3
