### Supported Resource Management Properties
The `k3s` scheduler supports a minimal list of resource _limits_ and _reservations_. The following properties are supported:
#### Resource Limits
> [!NOTE]
> Cron tasks retrieve resource limits based on the computed cron task ID. If unspecified, the default will be 1 CPU and 512m RAM.
The `k3s` scheduler supports a minimal list of resource _limits_ and _reservations_:
- cpu: is specified in number of CPUs a process can access.
- memory: should be specified with a suffix of `b` (bytes), `k` (kilobytes), `m` (megabytes), `g` (gigabytes). Default unit is `m` (megabytes).
- memory: should be specified with a suffix of `b` (bytes), `Ki` (kilobytes), `Mi` (megabytes), `Gi` (gigabytes). Default unit is `Mi` (megabytes).
#### Resource Reservations
If unspecified for any task, the default reservation will be .1 CPU and 128Mi RAM, with no limit set for either CPU or RAM. This is to avoid issues with overscheduling pods on a cluster. To avoid issues, set more specific values for at least resource reservations.
