Elastic 8.0 security by default: Minimal setup with Docker for a 3 node cluster + Kibana

commands.sh

// Start the first node and keep the generated security credentials handy
docker run -e ES_JAVA_OPTS="-Xms1g -Xmx1g" -p 9200:9200 -it docker.elastic.co/elasticsearch/elasticsearch:8.0.0

// Check if the node has started correctly
curl --insecure --user elastic https://localhost:9200/

// Add your second node
docker run -e ENROLLMENT_TOKEN="..." -e ES_JAVA_OPTS="-Xms1g -Xmx1g" -it docker.elastic.co/elasticsearch/elasticsearch:8.0.0

// Check if it has joined the cluster
curl --insecure --user elastic https://localhost:9200/_cat/nodes

// Add the third node
docker run -e ENROLLMENT_TOKEN="" -e ES_JAVA_OPTS="-Xms1g -Xmx1g" -it docker.elastic.co/elasticsearch/elasticsearch:8.0.0
