# Exploring Operator Catalogs

## Get a OLM Catalog Item

$ podman run -it --rm --entrypoint /bin/cat \
  registry.redhat.io/redhat/redhat-operator-index:v4.12 \
  /configs/cluster-logging/catalog.json > catalog.json

## Delve into the catalog item

### Get the list of related images the operator claims it uses

$ jq 'select(.relatedImages) | .name, .relatedImages' catalog.json
"cluster-logging.5.5.18"
[
