I’ve never gotten a sink connector working, so asking for some assistance.
I got the following docker-compose.yml file (following below this is the docker-compose.yml file used to bring up my ElasticSearch, Logstash and Kibana environment.
For my first lab I want to sink a topic called “random” into Elastic, I’m generating face data in Golang, and publishing this onto the topic.
For my second example, once I got the above working, I want to use filebeat to read a log file, push it onto a topic, lets call it filelogs, I will try and tag the file using beats metadata ability with the host name, which I want to use as the key for the messages.
I’ve come across the following blog : Kafka Elasticsearch Connector Tutorial with Examples
But don’t know what to copy over (add to my Confluent docker-compose.yml file, or maybe self contain in it’s own docker-compose.yml file) and what to configure where.
