How can I get specific field of some log message using gcloud? I am currently using this command:

gcloud logging read "logName=projects/some_project/logs/stdout AND resource.type:k8s_container and resource.labels.cluster_name=testing AND resource.labels.namespace_name=test" --limit 10 --format json

I'm guessing this should be something related to SELECT (as read in gcloud's standard sql guide for bigquery: https://cloud.google.com/bigquery/docs/reference/standard-sql/query-syntax)
