AWS offers a "Public Gallery" of Docker images for their ECR service. For example, they have this MediaWiki image https://gallery.ecr.aws/docker/library/mediawiki
I would always use the 'standard' images from Docker Hub (https://hub.docker.com/_/mediawiki) which receive from the 'official' WMF Image Repository https://docker-registry.wikimedia.org/ <ref>https://wikitech.wikimedia.org/wiki/Kubernetes/Images</ref> and operations <ref>https://github.com/wikimedia/operations-docker-images-docker-pkg/</ref><ref>https://www.mediawiki.org/wiki/User:GLavagetto_(WMF)/Container_image_policy_for_production</ref>.
