By default docker stats produces streaming output. Is there any way to get a single snapshot of the stats output?

You can look it up with docker inspect or docker ps --no-trunc . Putting everything together to look at the memory metrics for a Docker container, take a look at the following paths: /sys/fs/cgroup/memory/docker/<longid>/ on cgroup v1, cgroupfs driver. /sys/fs/cgroup/memory/system.
The docker stats command returns a live data stream for running containers. To limit data to one or more specific containers, specify a list of container names or ids separated by a space. You can specify a stopped container but stopped containers do not return any data.
Run the docker stats command to display the status of your containers. Memory is listed under the MEM USAGE / LIMIT column. This provides a snapshot of how much memory the container is utilizing and what it's memory limit is.
docker stats has the --no-stream argument
docker stats --no-stream container_name
You can get the extended usage information for each of the docker commands with docker help <command_name> and the list of all commands with docker help
