 - If `memswap_limit` is set to a positive integer, then both `memory` and `memswap_limit` must be set. `memswap_limit` represents the total amount of memory and swap that can be used, and `memory` controls the amount used by non-swap memory. So if `memory`="300m" and `memswap_limit`="1g", the container can use 300m of memory and 700m (1g - 300m) swap.
 - If `memswap_limit` is set to 0, the setting is ignored, and the value is treated as unset.
 - If `memswap_limit` is set to the same value as `memory`, and `memory` is set to a positive integer, the container does not have access to swap.
