The syntax for running a container with limited memory and additional swap memory is: sudo docker run -it -memory="" -memory-swap="" įor instance, to run a container from the Ubuntu image, assigning 1 GB of RAM for the container to use and reserving 1 GB of RAM for swap memory, type: sudo docker run -it -memory="1g" -memory-swap="2g" ubuntu To run a container with an additional 1 GB of swap memory, set the swap memory to 2 GB.

The swap includes the total amount of non-swap memory plus the amount of swap memory reserved as backup.įor example, if you set -memory to 1 GB, as in the example above, the amount of swap memory needs to be more than that. Before doing this, you should already have the maximum memory ( -memory) of the non-swap memory set. To configure this additional RAM space, define the total amount of swap memory. Although this is a useful feature, it is not a recommended practice as it slows down performance. It does this by ignoring the memory limitation and writing directly to the disk. Using the swap option allows you to store data even after all RAM assigned to the container has been used up. For example, to limit the container with 1 GB of RAM, add -memory="1g".įor example, to run an instance of an Ubuntu container and set the memory limit to 1 GB, the command is: sudo docker run -it -memory="1g" ubuntu Set Swap to Disk Memory Limit The value of memory_limitshould be a positive integer followed by the suffix b, k, m, or g (short for bytes, kilobytes, megabytes, or gigabytes). The command should follow the syntax: sudo docker run -it -memory=""
Within the command, specify how much memory you want to dedicate to that specific container. Alternatively, you can use the shortcut -m. To limit the maximum amount of memory usage for a container, add the -memory option to the docker run command.
