😭 Deploy PR Preview failed.

Marking as a draft since the images generated in _site/assets/images/social are being deleted during the build

yeah jekyll needs to know about the images - you can't just dump them into directories that comes from direct copies.

I had this issue in the past - trying to recall what was the fix...

so yeah, now i recall - you need to have it be a full plugin OR commit them to the actual repo.

Did you try see if https://github.com/boyvanamstel/jekyll-gensocial might just work?

actually gen-scoial could be useful for the blog style content. maybe https://github.com/jekyll/jekyll-seo-tag in combination would be good?

for ascidoc might just steal the approach of gen-social to generate into the source dir that could be in a git ignored folder?

I've given https://github.com/boyvanamstel/jekyll-gensocial a try and here are my impressions:

Pros

• It works for blog posts
• It lets you override the default settings per blog post (https://github.com/boyvanamstel/jekyll-gensocial#overrides)

Cons

• It only works for blog posts (Under _posts)
• You MUST have an image: attribute in the blog post otherwise nothing happens
• Files are generated inside assets/images, changing your source tree (that's why the generated images are not deleted during the build)
• The generated text isn't center-aligned

In case you're curious, I've pushed a working configuration in https://github.com/gastaldi/quarkusio.github.io/tree/jekyll_gensocial

@gastaldi what's the status of this?

It works, but the generated files' sizes surpass the maximum allowed upload size in surge.sh

This might help: https://github.com/marketplace/actions/imagemagick-action. I've used ImageMagick in the past to resize images. In that case they were pictures of fish I was batch-processing, but the principle would be similar.

... or we could do the equivalent in code, maybe with this: https://github.com/rmagick/rmagick. That would have the advantage of being the same locally and in GitHub ... and the disadvantage that ImageMagick has some native components, so the install might be a bit fiddly. Or it might not be - I haven't tried it via a gem.

@gsmet according to your suggestion, I added a config that skips the social image generation during preview and it seems to work.

boy this is slow locally ...how long does it take you to build?

The first build is slow indeed. The subsequent ones are faster

I run this locally and it generates social images but I only see "quarkus_card.png" in og:image of blogs is that expected?

Yes, because I am only generating social images for guides. See https://github.com/quarkusio/quarkusio.github.io/pull/1725/files#diff-41b71bd8e56b7f1670ccca46cbf0dec0b906a961b0a9c140914425009ecc879aR36 and https://github.com/quarkusio/quarkusio.github.io/pull/1725/files#diff-41b71bd8e56b7f1670ccca46cbf0dec0b906a961b0a9c140914425009ecc879aR11

mkay - but aren't the blog posts the most shared ones for social images?

why only guides?

So far I have only shared guides in my chat messaging apps (which is why I made this change). That may work, need to improve the script to read from the blog directory too.

@gastaldi fun - i rarely share guides - its more blog posts :)
