Docker file for V3

[Pascal76]

Hello,

Is it possible to provide a docker file for the new release please ? :)

[jszuminski]

Thanks for the question @Pascal76!

We are planning to create setup guides for different tools/environments, including Docker, soon (after all the bug issues on GitHub are solved). Thus, I'm leaving this issue as open.

In the meantime, I will try to guide you towards a file that works for you, here's a basic setup:

# choose your version of node
FROM node:latest

# set all the Export Server related environment variables
ENV ACCEPT_HIGHCHARTS_LICENSE=1
ENV HIGHCHARTS_VERSION=11.2.0

# get the export server
RUN npm install [email protected] -g

EXPOSE 8080
# ... continue as below

Let me know if that works for you or if you need anything else.

Thanks @jakubSzuminski

Here's a working dockerfile:
Dockerfile.zip

(it's in a zip because GitHub doesn't like docker for some reason)

Great, thanks! This will be very helpful for us and other users.

size: 2.6GB vs 356MB before V3 !

size: 2.6GB vs 356MB before V3 !

The Dockerfile I posted a few comments up is only 723MB and still works fine, just need to bump some version numbers.

Most of that size is chrome and it's deps, which is unavoidable.

[tibberg]

wouldnt make it more sense to use the ghcr.io/puppeteer/puppeteer as the FROM? Afaik the puppeteer should be used with the same chrome version, for compatibility reasons, so it would make more sense to use the base image which contains both the chrome and the puppeteer already and they are compatible for sure.
see https://pptr.dev/guides/docker

[davidseverwright]

That image requires SYS_ADMIN, which isn't possible in a lot of cloud providers and will fail any security audit.

[tibberg]

I don't fully understand why that is reuquired by them (and why it is not just a suggestion). But if you look at the Dockerfile for that, it is quite similar to the above suggested ones. And acutally we were able to run an older version of the highcharts export server without the SYS_ADMIN privilege in AWS eks. Here is what we did at that time:

FROM ghcr.io/puppeteer/puppeteer:20.9.0
USER pptruser
WORKDIR /home/pptruser
RUN npm i [email protected]
CMD node node_modules/highcharts-export-server/bin/cli.js --enableServer true

[hubaksis]

My docker file, around 900mb.

FROM node:lts-alpine
ENV NODE_ENV=production
ENV HIGHCHARTS_VERSION=11.4.0
ENV SERVER_ENABLE=true
ENV SERVER_SSL_ENABLE=true

RUN apk add --no-cache \
      chromium \
      nss \
      freetype \
      harfbuzz \
      ca-certificates \
      ttf-freefont \
      nodejs \
      yarn

ENV PUPPETEER_EXECUTABLE_PATH=/usr/bin/chromium-browser
RUN npm install highcharts-export-server -g
COPY . .
EXPOSE 3000
# RUN chown -R node /usr/src/app
# USER node
ENTRYPOINT ["highcharts-export-server", "--enableServer", "1"]

Any ideas why environment variables like SERVER_ENABLE, SERVER_PORT are not used by the export server? I have to pass them as parameters to ENTRYPOINT.

[Pascal76]

could you tell me the command line to install the master please ?

I tried several methods without success
RUN npm install highcharts-export-server@master -g
RUN npm install https://github.com/highcharts/node-export-server.git#master -save -g
...
