It looks that some container images are hosted by GCR 👀
This may be because Cloud Run can use only with Artifact Registry, GCR, Docker Hub.
So it would be nice to consider for GCR 🤔
WDYT @khanhtc1202 ?

@ffjlabo good catch!
if we GCR only when Cloud Run, so ideally we could bring all images to GCR
however, not sure if PipeCD want to rely on a specific vendor?
@khanhtc1202

btw, even we won't bring all the images to GCR, we could add more configuration for the matrix by this way

already push the change base on that, please check below comment

Guys, I know that it's hard to test the workflow publish build and push image by matrix from this PR
Please give me sometime on a test then show you how with the current change
