slim docker image

[vogler]

Current Docker image based on ubuntu:jammy is 1.12GB.

Tried out slim docker images with VNC (could be <400MB):

• https://github.com/jlesage/docker-baseimage-gui Alpine & Ubuntu
• https://github.com/jlesage/docker-firefox 377MB base, Alpine only

Alpine: installing deps and running firefox did not work - Playwright does not support Alpine: issue. Got /usr/bin/firefox to launch, but could not load profile.
Ubuntu: may work, but somehow could not install up-to-date nodejs to run npx playwright.

Other projects, but only supporting Chromium:

• https://github.com/Zenika/alpine-chrome
• https://github.com/fivemru/playwright-docker-alpine

You can reduce 1.6 Mb by adding --no-cache-dir to pip install :D
I see that there is a lot of data been installed, FF is around 242 Mb, layer with VNC is already 644 Mb

P.S. you can see what was installed and how it is big with each layer with dive, simply do after installation:

dive ghcr.io/vogler/free-games-claimer

[vogler]

Yea, I already checked all layers. The main problem is that Playwright does not support Alpine and Ubuntu with all its deps is quite heavy in comparison.
Could probably port some tricks (sep. build stages, upx, TigerVNC) from https://github.com/jlesage/docker-baseimage-gui/blob/master/Dockerfile, but seems like a lot of work.

There is not "tiny" image with Playwright at all... They are already around 674 Mb, so in our case we even more efficient. As this is most weight, I do not think that Alpine will give you benefit over Ubuntu here.

From the small points, we ca update command to not copy .git and .github folders to the container, e.g. by:

COPY *.* .

My personal Record is 965 vs 972 MB.

just port the script to chrome and use the above projects.

[vogler]

@xAffan All scripts used Chrome initially, then got captcha challenges (and some other issues) which was resolved by changing to Firefox. See #39.

How about puppeteer stealth plugins?

Just a side note, and maybe not what you want. Why don't you just follow the steps which are described in the Readme.md under "I want to run without Docker or develop locally."

On Windows I just installed Git for Windows, nodejs and python3 (didn't test if it's necessary if I don't need apprise), than ran npm install inside the local repo folder (i think unnecessary as npm update will do it if necessary) and added a batch file which is ran every X hours by task scheduler:

cd /d "%~dp0"

git pull --quiet

@REM by default all browsers (chromium, firefox, webkit) are downloaded
@REM disable browser download during npm update/install
set PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
cmd /c npm update --silent

@REM by default browsers are downloaded to %LOCALAPPDATA%\pw-browsers
@REM set browser download location inside the free-games-claimer directory
@REM run npx in a separate cmd as npx will close the one it is running in
set PLAYWRIGHT_BROWSERS_PATH=%~dp0\pw-browsers
cmd /c npx --quiet playwright install firefox

node epic-games
node gog
node prime-gaming

@REM cleanup
rmdir /s /q "%LOCALAPPDATA%\ms-playwright" "%~dp0\data\screenshots\" "%~dp0\data\browser\cache2" "%~dp0\data\browser\startupCache" "%~dp0\data\browser\storage"
del /f "%~dp0\data\browser\favicons.sqlite" "%~dp0\data\browser\places.sqlite"

All requirements can actually be seen in Dockerfile and Readme.md. Up to you if you want to run it locally or prefer a Docker container, but it won't get much smaller than that.

How about puppeteer stealth plugins?

@xAffan What about them? The scripts have been using them from the beginning. With the stealth plugins Chrome got some captcha challenges, while Firefox didn't. You can check if the situation changed, but I guess not.

@ladiko python is only needed for apprise.
