How to disable security (username/password) on Elasticsearch Docker container?
Docker
Simply add the xpack.security.enabled=false env var:
docker run \ -p 9200:9200 \ -p 9300:9300 \ -e "discovery.type=single-node" \ -e "xpack.security.enabled=false" \ docker.elastic.co/elasticsearch/elasticsearch:5.6.3Ansible
When running the container using Ansible's docker_container, some yaml idiosyncrasies forces you to use 0 instead of false:
env: discovery.type: "single-node" xpack.security.enabled: 0 ..
