Each returned value has the following fields: .. code-block:: python { 'name': (str) cluster name, 'launched_at': (int) timestamp of last launch on this cluster, 'handle': (ResourceHandle) an internal handle to the cluster, 'last_use': (str) the last command/entrypoint that affected this cluster, 'status': (sky.ClusterStatus) cluster status, 'autostop': (int) idle time before autostop, 'to_down': (bool) whether autodown is used instead of autostop, 'metadata': (dict) metadata of the cluster, } Each cluster can have one of the following statuses: - ``INIT``: The cluster may be live or down. It can happen in the following cases: - Ongoing provisioning or runtime setup. (A ``sky.launch()`` has started but has not completed.) - Or, the cluster is in an abnormal state, e.g., some cluster nodes are down, or the SkyPilot runtime is unhealthy. (To recover the cluster, try ``sky launch`` again on it.) - ``UP``: Provisioning and runtime setup have succeeded and the cluster is live. (The most recent ``sky.launch()`` has completed successfully.) - ``STOPPED``: The cluster is stopped and the storage is persisted. Use ``sky.start()`` to restart the cluster. Autostop column: - The autostop column indicates how long the cluster will be autostopped after minutes of idling (no jobs running). If ``to_down`` is True, the cluster will be autodowned, rather than autostopped. Getting up-to-date cluster statuses: - In normal cases where clusters are entirely managed by SkyPilot (i.e., no manual operations in cloud consoles) and no autostopping is used, the table returned by this command will accurately reflect the cluster statuses. - In cases where the clusters are changed outside of SkyPilot (e.g., manual operations in cloud consoles; unmanaged spot clusters getting preempted) or for autostop-enabled clusters, use ``refresh=True`` to query the latest cluster statuses from the cloud providers. Args: refresh: whether to query the latest cluster statuses from the cloud provider(s). Returns: A list of dicts, with each dict containing the information of a cluster.
