Creating a volume to store log files outside of containers: docker-compose.yml, 3. The pipeline worked against all the documents I tested it against in the Kibana interface. Thanks for contributing an answer to Stack Overflow! This works well, and achieves my aims of extracting fields, but ideally I'd like to use Elasticsearch's (more powerful) ingest pipelines instead, and live with a cleaner filebeat.yml, so I created a working ingest pipeline "filebeat-7.13.4-servarr-stdout-pipeline" like so (ignore the fact that for now, this only does the grokking): I tested the pipeline against existing documents (not ones that have had my custom processing applied, I should note).
