ElasticSearch notifier development

The easiest way to develop BotKube with Elasticsearch notifier enabled is to install Elasticsearch on your local Kubernetes cluster.

Steps

1. Install Elasticsearch:

   helm repo add elastic https://helm.elastic.co
   helm install elasticsearch elastic/elasticsearch --set replicas=1 --set resources.requests.cpu="100m" --set resources.requests.memory="512M" --wait
   

2. Install BotKube with Elasticsearch, according to the Elasticsearch installation instruction, where:

   • ELASTICSEARCH_USERNAME is elastic,
   • ELASTICSEARCH_PASSWORD is changeme,
   • ELASTICSEARCH_ADDRESS is http://elasticsearch-master.default:9200.

   You don’t need to set index name, type, shards and replicas.

To review if the events are properly saved in Elasticsearch, follow these steps:

1. Do port forward:

   kubectl port-forward svc/elasticsearch-master 9200
   

2. Fetch Elasticsearch indices:

   curl http://localhost:9200/_cat/indices
   

3. Copy the index name with the botkube- prefix and export it as environment variable. For example:

   export INDEX_NAME="botkube-2022-06-06"
   

4. See Elasticsearch index details with logged events:

   curl http://localhost:9200/$INDEX_NAME/_search\?pretty
