Docker doesn't support i18n testing, problem with outdated base image

[MirKml]

What is your Scenario?

When I want to test pages in another language (Czech particularly) then English in Docker on CI, it doesn't work.
I discovered that it's necessary to install chromium-lang package

FROM testcafe/testcafe:3.7.1
USER root
RUN apk --no-cache add chromium-lang

This works for some weeks. But suddenly chromium doesn't start at all.
The reason was old base testcafe image. It contained old base libs for chromium. It was necessary to call always apk upgrade before apk add.
But it takes long time - it updates whole distro. It's also risky at all. It can upgrade e.g. node, which isn't compatible with testcafe in base image.

So can you add chromium-lang into your base image? What is your recommendation for running current updated chrome in docker with your base image? Can you make your base image up to date with latest browser releases?

What is the Current behavior?

Extending base docker image is necessary, but has drawbacks - updates complete distro, takes time and can break testcafe itself.

What is the Expected behavior?

Add chromium-lang into base image, this is mandatory. Tests multi-language webs should be possible without extending base image.
Regularly release new testcafe image when new browser is released or every month or two?

What is the public URL of the test page? (attach your complete example)

Hello,

Thank you for reaching out to us.

The last TestCafe docker image was built with chromium 131.0.6778.108-r0 from alpine packages. You can update your installation as follows to install a compatible chromium-lang version:

FROM testcafe/testcafe:3.7.1 

USER root 

RUN apk --no-cache add chromium-lang=131.0.6778.108-r0

This way, you should be able to avoid compatibility issues between chromium and chromium-lang. With this approach, you will not need to update complete distro.

Please let us know if this workaround helps.

Regarding

Add chromium-lang into base image, this is mandatory
and
Regularly release new TestCafe image when new browser is released or every month or two

We will add this task to our internal backlog.

Thanks. I will try later this week and let you know. Install particular versions is good solution for effective upgrade.

As I read on https://wiki.alpinelinux.org/wiki/Alpine_Package_Keeper - package version "pinning" can have some problems - some old versions can be deleted - for community packages, edge branch ..
So adding this one into your base image will be safer. Thanks for adding request into internal backlog.

Hm, seems that installing old package doesn't work, log from docker build @Bayheck

I see that old version is available in 3.20 alpine branch https://dl-cdn.alpinelinux.org/v3.20/community/x86_64/chromium-lang-131.0.6778.108-r0.apk but how long? It seems that upgrades come in to 3.20 regularly. After a while chromium-lang will be upgraded in 3.20 branch also.
It seems that old chromium-lang version pinning ins't good approach.
