zipkin-elasticsearch6 Docker image

The zipkin-elasticsearch6 testing image runs Elasticsearch 6.x for Elasticsearch storage integration.

To build openzipkin/zipkin-elasticsearch6, from the top level of the repository, run:

$ docker build -t openzipkin/zipkin-elasticsearch6:test -f docker/storage/elasticsearch6/Dockerfile .

You can use the env variable ES_JAVA_OPTS to change settings such as heap size for Elasticsearch.

Host setup

Elasticsearch is strict about virtual memory. You will need to adjust accordingly (especially if you notice Elasticsearch crash!)

# If docker is running on your host machine, adjust the kernel setting directly
$ sudo sysctl -w vm.max_map_count=262144

# If using docker-machine/Docker Toolbox/Boot2Docker, remotely adjust the same
$ docker-machine ssh default "sudo sysctl -w vm.max_map_count=262144"
