# Cluster

```python
from lium.sdk import Cluster
```

Defined in `lium.sdk.models`.

The pods of one multi-node rental, in node-rank order.

Node 0 is the natural ``MASTER_ADDR`` for ``torchrun``; every member reaches every other
over the private overlay (``10.42.0.<rank+1>``) that the cluster image raises on start.

```python
Cluster(id: str, pods: List[lium.sdk.models.PodInfo])
```
