If docker is running on your host machine, adjust the kernel setting directly - Zipkin

zipkin-opensearch2 Docker image

The zipkin-opensearch2 testing image runs OpenSearch 2.x for Elasticsearch storage integration.

To build openzipkin/zipkin-opensearch2:test, from the top-level of the repository, run:

bash

$ DOCKER_FILE=docker/test-images/zipkin-opensearch2/Dockerfile build-bin/docker/docker_build openzipkin/zipkin-opensearch2:test

You can use the env variable OPENSEARCH_JAVA_OPTS to change settings such as heap size for OpenSearch.

Host setup

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

bash

# 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"

# If using colima, it is similar as well
$ colima ssh "sudo sysctl -w vm.max_map_count=262144"
