+This variable lets you pass whatever flags you need to the docker run command. It is a list, to which you can add multiple types of flags:
+ - ```yaml
+    - key: value
+    # will pass the flag --key "value" to the container.
+    Example:
+      - network: host
+ - ```yaml
+    - simple_key
+    # will pass the flag --simple_key to the container.
+    Example:
+      - privileged
+ - ```yaml
+    - key:
+        - value1
+        - value2
+    # will pass the flags --key "value1" --key "value2" to the container.
+    Example:
+      - volume:
+          - /path/on/host:/path/on/container
+          - /var/run/docker.sock:/var/run/docker.sock:ro
 
 ```yaml
 docker_systemd_service_name: "{{ docker_systemd_service_container_name }}_container"  # by default, set to "{{ docker_systemd_service_container_name }}_container"
