• Update restart policy to apply when a specific container exits: docker update --restart=always|no|on-failure|unless-stopped container_name
• Update the policy to restart up to three times a specific container when it exits with non-zero exit status: docker update --restart=on-failure:3 container_name
• Update the number of CPUs available to a specific container: docker update --cpus count container_name
• Update the memory limit in [M]egabytes for a specific container: docker update --memory limitM container_name
• Update the maximum number of process IDs allowed inside a specific container (use -1 for unlimited): docker update --pids-limit count container_name
• Update the amount of memory in [M]egabytes a specific container can swap to disk (use -1 for unlimited): docker update --memory-swap limitM container_name
