Fails to find chromium binary #519

What happened:

My workplace want the image renderer to be installed alongside Grafana in an AlpineLinux-based Docker container. This is very similar to what Grafana do in their own containers, so should be a supported and working configuration.

When doing this, the renderer plug-in starts, but then fails to find Chromium. No images are being rendered.

What you expected to happen:

I expected it to render images (like it says on the tin).

How to reproduce it (as minimally and precisely as possible):

We use supervisord in an AlpineLinux container to launch the plug-in…

Rough Dockerfile set-up:

FROM alpine:3.19
ENV GF_RENDERING_SERVER_URL=http://localhost:8081/render
ENV GF_RENDERING_CALLBACK_URL=http://localhost:3000/
ENV GF_PLUGIN_RENDERING_CHROME_BIN=/usr/bin/chromium-browser

ARG GRAFANA_IMG_RENDER_REPO=https://github.com/grafana/grafana-image-renderer.git
ARG GRAFANA_IMG_RENDER_VER=3.10.3

RUN apk add --no-cache \
        openssl \
        ca-certificates \
        chromium \
        supervisor \
        bash \
        git \
        nodejs \
        yarn \
        udev \
        ttf-opensans \
    && git clone --depth=1 --branch=v${GRAFANA_IMG_RENDER_VER} \
        ${GRAFANA_IMG_RENDER_REPO} /opt/grafana-image-renderer \
    && cd /opt/grafana-image-renderer \
    && yarn install --pure-lockfile \
    && yarn run build \
    && apk del yarn git

There are other steps like creating a grafana user (with a fixed UID/GID), importing a pre-built Grafana binary and its front-end, but that's the gist of how the image renderer plug-in is installed. supervisord then launches it with this command:

[supervisord]
logfile=/dev/null
pidfile=/var/run/supervisord.pid
nodaemon=true

[program:renderer]
directory=/opt/grafana-image-renderer
command=env HOME=/home/grafana /usr/bin/node build/app.js server --port=8081
user=grafana
redirect_stderr=true
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
auto_start=true
autorestart=true

Anything else we need to know?:

Grafana itself is working just fine (all functions except exporting a rendered image of a dashboard work). Exporting a rendering image fails.

The log message I get is:

~ # chromium --version
Chromium 124.0.6367.78 Alpine Linux

What I've tried:

  • Tried using grafana-cli install grafana-image-renderer: fails and crashes Grafana because it tries to launch a binary linked against glibc not the musl C library that AlpineLinux uses.
  • Tried using the grafana-image-renderer package shipped by AlpineLinux: saw the above message
  • Tried installing grafana-image-renderer via git: saw the above message
  • Tried symlinking /usr/bin/chromium-browser to /usr/bin/chrome (like is done in Grafana's own image renderer container): saw the above message
  • Tried setting GF_PLUGIN_RENDERING_CHROME_BIN as per the troubleshooting docs: saw the above message

Environment:

  • Grafana Image Renderer version: 3.10.3
  • Grafana version: 9.4.0
  • Installed plugin or remote renderer service: remote renderer service (inside the same container)
  • OS Grafana Image Renderer is installed on: Alpine Linux 3.19
  • User OS & Browser: Gentoo Linux/AMD64 & Firefox 115.9.1esr
  • Others:

More tinkering, it seems I have to set both GF_PLUGIN_RENDERING_CHROME_BIN AND CHROME_BIN.

Not sure if maybe process.env.CHROME_BIN can be set to process.env.GF_PLUGIN_RENDERING_CHROME_BIN before importing the underlying library to gracefully handle this… but the error message is misleading to say the least.

I'll leave this open for a bit while I test, but I think I may have found the answer to the question.
