I have two projects in Google Cloud. On the first project I have some images in the container registry and i'm using it in the gke.
When I trie to create a container in the second project, it gives me a error:
Error: Status 403 trying to pull repository project-1/image-x: "Access denied."
How can i use those images in the gke but in different project? I don't want to create the same images in the second project.
In your second project (the GKE project), look at the IAM permissions and you will see a user similar to: 123456789-compute@developer.gserviceaccount.com.
Then in your first project (the container registry project), grant that user the Storage Object Viewer permission to allow GKE to pull images.
You can modify who the images are visible to by using the access control settings available on the Google Cloud Storage bucket that they're stored in.

If you just want to make all your images readable to the entire world, then the command from this other StackOverflow answer should help: gsutil -m acl -r set public-read gs://bucket-name gsutil -m defacl set public-read gs://bucket-name
This is discussed in detail in my answer here: Access google container registry without the gcloud client
