+h2(#configure_docker_daemon). Configure the Docker daemon
+
+Depending on your anticipated workload or cluster configuration, you may need to tweak Docker options.
+
+For information about how to set configuration options for the Docker daemon, see https://docs.docker.com/config/daemon/systemd/

+h3. Changing ulimits
+
+Docker containers inherit ulimits from the Docker daemon. However, the ulimits for a single Unix daemon may not accommodate a long-running Crunch job. You may want to increase default limits for compute containers by passing @--default-ulimit@ options to the Docker daemon. For example, to allow containers to open 10,000 files, set @--default-ulimit nofile=10000:10000@.
