+### `resources`
+`resources` configures physical resource constraints for container to run on platform. Those constraints can be configured as:
+- `limits`: The platform must prevent the container to allocate more.
+- `reservations`: The platform must guarantee the container can allocate at least the configured amount.
+
+The following can be configured:
+- `cpus`: `cpus` configures a limit or reservation for how much of the available CPU resources, as number of cores, a container can use.
+- `memory`: `memory` configures a limit or reservation on the amount of memory a container can allocate, set as a string expressing a byte value.
+- `pids`: `pids` tunes a container’s PIDs limit, set as an integer.
