When using docker it is usually best to configure services via environment variables. To set a password for the elasticsearch service you can run the container using the env variable ELASTIC_PASSWORD:

docker run -e ELASTIC_PASSWORD=`openssl rand -base64 12` -p 9200:9200 --rm --name elastic docker.elastic.co/elasticsearch/elasticsearch-platinum:6.2.4

openssl rand -base64 12 sets a random value for the password
