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 on Alpine Linux, small and fast)
9# apify/actor-node-chrome (Node.js + Chrome on Debian)
10# apify/actor-node-chrome-xvfb (Node.js + Chrome + Xvfb on Debian)
11# For more information, see https://docs.apify.com/actor/build#base-images
12# Note that you can use any other image from Docker Hub.
13FROM apify/actor-node-basic
14
15# Second, copy just package.json since it should be the only file
16# that affects "npm install" in the next step, to speed up the build
17COPY package.json ./
18
19# Install NPM packages, skip optional and development dependencies to
20# keep the image small. Avoid logging too much and print the dependency
21# tree for debugging
22RUN npm --quiet set progress=false \
23 && npm install --only=prod --no-optional \
24 && echo "Installed NPM packages:" \
25 && npm list || true \
26 && echo "Node.js version:" \
27 && node --version \
28 && echo "NPM version:" \
29 && npm --version
30
31# Next, copy the remaining files and directories with the source code.
32# Since we do this after NPM install, quick build will be really fast
33# for most source file changes.
34COPY . ./
35
36# Optionally, specify how to launch the source code of your actor.
37# By default, Apify's base Docker images define the CMD instruction
38# that runs the Node.js source code using the command specified
39# in the "scripts.start" section of the package.json file.
40# In short, the instruction looks something like this:
41#
42# CMD npm startmain.js
