+## Sample Docker Compose file for development
+
+This sample file starts one OpenSearch node and a container for OpenSearch Dashboards for development by disabling security plugin.
+
+```yml
+version: '3'
+services:
+  opensearch-node1:
+    image: opensearchproject/opensearch:{{site.opensearch_version}}

+      - "OPENSEARCH_JAVA_OPTS=-Xms512m -Xmx512m" # minimum and maximum Java heap size, recommend setting both to 50% of system RAM
+      - "DISABLE_INSTALL_DEMO_CONFIG=true" # disables execution of install_demo_configuration.sh bundled with security plugin, which installs demo certificates and security configurations to OpenSearch
+      - "DISABLE_SECURITY_PLUGIN=true" # disables security plugin entirely in OpenSearch by setting plugins.security.disabled: true in opensearch.yml
+      - "discovery.type=single-node" # disables bootstrap checks that are enabled when network.host is set to a non-loopback address

+
+The `"DISABLE_SECURITY_DASHBOARDS_PLUGIN=true"` disables security dashboards Plugin in OpenSearch Dashboards by removing security dashboards plugin folder, removing all related settings in `opensearch_dashboards.yml`, and sets `opensearch.hosts` entry protocol from HTTPS to HTTP. This step is not reversible as the security dashboards plugin is removed in the process. If you want to re-enable security for OpenSearch Dashboards, you need to start a new container with `DISABLE_SECURITY_DASHBOARDS_PLUGIN` unset, or false.
