Dockerfile
# This is a template for a Dockerfile used to run acts in Actor system.# The base image name below is set during the act build, based on user settings.# IMPORTANT: The base image must set a correct working directory, such as /usr/src/app or /home/userFROM apify/actor-node-basic:v0.21.10
# Second, copy just package.json and package-lock.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 --all || true) \ && echo "Node.js version:" \ && node --version \ && echo "NPM version:" \ && npm --version
# Copy source code to container# Do this in the last step, to have fast build if only the source code changedCOPY . ./
