Class Method Details

.build_from_env(klass) ⇒ Object

Helper method for building ElasticGraph components from our lambda ENV vars. ‘klass` is expected to be `ElasticGraph::Admin`, `ElasticGraph::GraphQL`, or `ElasticGraph::Indexer`.

This is meant to only deal with ENV vars and config that are common across all ElasticGraph components (e.g. logging and OpenSearch clients). ENV vars that are specific to one component should be handled elsewhere. This accepts a block which can further customize configuration as needed.
