Opensearch cold start

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):

Opensearch 2.14.0

Describe the issue:

I have a working OpenSearch instance in a Docker container, and my issue is related to cold starts. I’m getting a timeout if I don’t make any queries for even just a few minutes (like 10 or 15 minutes). After I try again, it works, but this is not the behavior I would like.

Is any configuration I can tune to avoid this problem? This is the docker compose I used to install opensearch:

version: '3.8'
services:
  opensearch:
    image: opensearchproject/opensearch:latest
    container_name: opensearch
    environment:
      - discovery.type=single-node
      - "OPENSEARCH_JAVA_OPTS=-Xms512m -Xmx3g"
      - "OPENSEARCH_SECURITY_ENABLED=true"
      - "OPENSEARCH_SECURITY_AUTHENTICATION_AUTHC_BASIC_INTERNAL_USERS=admin:pass"
      - "OPENSEARCH_INITIAL_ADMIN_PASSWORD=pass"
    ports:
      - "9200:9200"
    volumes:
      - /home/azureuser/opensearch/volume:/usr/share/opensearch/data
    deploy:
      resources:
        limits:
          memory: 4g

Configuration:

---

cluster.name: docker-cluster

# Bind to all interfaces because we don't know what IP address Docker will assign to us.

network.host: 0.0.0.0

# # minimum_master_nodes need to be explicitly set when bound on a public IP

# # set to 1 to allow single node clusters

# discovery.zen.minimum_master_nodes: 1

# Setting network.host to a non-loopback address enables the annoying bootstrap checks. "Single-node" mode disables them again.

# discovery.type: single-node
