docker container update [options] container [container...]

docker container update dynamically updates resource constraints and restart policies for one or more running containers without requiring a restart. This allows administrators to adjust resource limits in response to changing workload requirements or to correct initial configuration mistakes.
While most resource limit changes take effect immediately, some settings may require a container restart to fully apply. The restart policy update is particularly useful for changing whether containers should automatically restart on failure or system boot.
