Guidance To Run In Docker

[barrycarey]

Hello,

I'll start by saying I know there's a template repo for a Docker build. However, I'm attempting to integrate with an existing project so I was trying to avoid using that repo if possible.

I've tried a few different variations including the Python base image with Chrome installed. An Alpine base image with VNC installed. Basically this example for UC.

They always yield the same results, logs below.

Any advice on what I might be missing?

[stephanlensky]

Running Chrome in Docker is fairly challenging, and honestly I am not too familiar with Alpine Linux. It's hard to know what's going wrong here just from a quick look.

Have you confirmed that you're able to launch Chrome in the container if you just try starting it directly? (without using Zendriver)

Even if you don't use the template, I would at least suggest taking a look at how I'm doing things in stephanlensky/zendriver-docker. The template is based on another image I created, stephanlensky/swayvnc-chrome, which you might find useful for a more minimal example of running Chrome in Docker.

My approach is fairly different from the repo you linked though, since I am using Debian & Wayland (rather than X11).

[kriiv]

@stephanlensky Is there a chance to release a similar Docker image to the graphical/VNC one you've released that just does Headless?

[therealpurplemana]

How much CPU and ram are you using to run the container? I've found it to be very sensitive when Chrome initially launches. It has a big memory/cpu spike, and then comes back down to normal, but it fails to start if it can't get past that.
