Dockerfile

1# Dockerfile contains instructions how to build a Docker image that
2# will contain all the code and configuration needed to run your actor.
3# For a full Dockerfile reference,
4# see https://docs.docker.com/engine/reference/builder/
5
6# First, specify the base Docker image. Apify provides the following
7# base images for your convenience:
8#  apify/actor-node-basic (Node.js 10 on Alpine Linux, small and fast)
9#  apify/actor-node-chrome (Node.js 10 + Chrome on Debian)
10#  apify/actor-node-chrome-xvfb (Node.js 10 + Chrome + Xvfb on Debian)
11# For more information, see https://apify.com/docs/actor#base-images
12# Note that you can use any other image from Docker Hub.
13FROM apify/actor-node-chrome
14
15# Copy all files and directories with the source code
16COPY . ./
17
18# Install NPM packages, skip optional and development dependencies to
19# keep the image small. Avoid logging to much and print the dependency
20# tree for debugging
