For deploying a Moloch instance with Docker, please have a working Elasticsearch deployment running and a way to access it. You can edit the Dockerfile environment variables and the etc/config.ini file to set your configuration settings.
The command below uses a Docker link to link the two containers together:
sudo sysctl -w vm.max_map_count=262144
sudo docker run -p 9200:9200 -p 9300:9300 -itd --name elasticsearch docker.elastic.co/elasticsearch/elasticsearch:6.2.4
sudo docker run -itd -p 8005:8005 --cap-add NET_RAW --cap-add NET_ADMIN --link elasticsearch:elasticsearch --name moloch moloch
For deploying multiple instances, it is recommended that you use a statefulset for both Elasticsearch and Moloch to prevent changes in the container/pod states. You may also want to use a config map for the config.ini file to further customize your deployment.
