Configure ElasticSearch 8

The Log Export Container uses fluentd elasticsearch output plugin and currently it only supports ElasticSearch 8. In order to enable it you need to specify LOG_EXPORT_CONTAINER_OUTPUT=elasticsearch-8 and provide the following variables:

• ELASTICSEARCH_HOSTS. List of ElasticSearch hosts separated by comma, e.g. https://username:password@custom-host.com:port/path,http://localhost:9200.
• ELASTICSEARCH_INDEX_NAME. ElasticSearch index name, e.g. my-index

NOTE: In case you need to connect to a secure ElasticSearch deployment (if you’re using Elastic Cloud or something similar) you need to add the credentials to the ELASTICSEARCH_HOSTS variable. E.g., ELASTICSEARCH_HOSTS=https://username:password@xxxxxxx.us-central1.gcp.cloud.es.io:443
