+|use_existing|boolean|If possible, use an existing (non-failed) container to satisfy the request instead of creating a new one.|Default is true|
+|log_uuid|string|Log collection containing log messages provided by the scheduler and crunch processes.|Null if the container has not yet completed.|
+|output_uuid|string|Output collection created when the container finished successfully.|Null if the container has failed or not yet completed.|
+|filters|string|Additional constraints for satisfying the container_request, given in the same form as the filters parameter accepted by the container_requests.list API.|
+|runtime_token|string|A v2 token to be passed into the container itself, used to access Keep-backed mounts, etc. |Not returned in API responses. Reset to null when state is "Complete" or "Cancelled".|
+|runtime_user_uuid|string|The user permission that will be granted to this container.||
+|runtime_auth_scopes|array of string|The scopes associated with the auth token used to run this container.||
+
+h2(#priority). Priority
+
+The @priority@ field has a range of 0-1000.
+
+Priority 0 means no container should run on behalf of this request, and containers already running will be terminated (setting container priority to 0 is the cancel operation.)
+
+Priority 1 is the lowest priority.
+
+Priority 1000 is the highest priority.
+
+The actual order that containers execute is determined by the underlying scheduling software (e.g. SLURM) and may be based on a combination of container priority, submission time, available resources, and other factors.
+
+In the current implementation, the magnitude of difference in priority between two containers affects the weight of priority vs age in determining scheduling order. If two containers have only a small difference in priority (for example, 500 and 501) and the lower priority container has a longer queue time, the lower priority container may be scheduled before the higher priority container. Use a greater magnitude difference (for example, 500 and 600) to give higher weight to priority over queue time.
