name: Literal\["SchedulerPlaced", "NetworkingIPAssigned", "VMStarted", 14 more] Name of the event that describes the kind event that happened. - SchedulerPlaced: It’s the first event that creates a container placement. It happens when the Containers runtime was able to retrieve deployment resources and start verifying everything is correct. - NetworkingIPAssigned: It’s sent when the Containers runtime maps the IP to the container. - VMStarted: It’s sent when the Containers runtime starts the VM. The container might remain unhealthy at this point. - ImagePulled: It’s sent when the Containers runtime pulls the image successfully. - ImagePullError: It’s sent when the Containers runtime is having issues pulling the image. The message and details have more information on what happened for debugging. - VMFailedToStart: It’s sent when the Containers runtime was unable to boot the VM. - VMStopping: It’s sent when the scheduler is stopping the VM. - VMStopped: It’s sent when the VM finally exits. - VMFailed: It’s sent when the scheduling of the VM failed in the current location. - RuntimeStartFailed: It’s sent when the runtime hits an internal error. - SSHStarted: It’s sent when the container gains network connectivity and opens the SSH port. Containers only send this event when SSH keys exist. - CheckUpdate: Sent when the status of a health or readiness check changes. This may also affect the health status of the placement. - DurableObjectConnected: Sent when a durable object instance connects and gains control of the deployment. This event is only sent for durable object deployments. It is sent after VMStarted. - ContainerStarted: It’s sent when the container starts running.

Link to this property instance\_id: str An instance ID represents an identifier of an instance configuration that maintains an underlying placement. Link to this property
Link to this property
instances: CcScheduledApplicationHealthInstances Shows a count of application instance states. active: int Number of instances whose runtime reports the container as running (container\_status = “running”). This is a subset of the placements that remain up: an instance that is already bound to a Durable Object and serving traffic is counted under “assigned” until its container\_status catches up to “running”, so container\_status can briefly lag Durable Object attachment under churn. To estimate running, Durable-Object-bound instances, sum “active” + “assigned” rather than reading “active” alone. Link to this property assigned: int Number of instances bound to a Durable Object with a running placement whose container\_status remains behind “running”. These count as live, serving instances; “active” + “assigned” approximates the running, Durable-Object-bound count. Link to this property
Link to this property

Based on a sample of target-version instances rather than a full count. - “pending”: Zero target-version instances exist yet. - “healthy”: Every sampled target-version instance reports running or active. - “degraded”: Some sampled instances remain starting or scheduling. - “unhealthy”: One or more sampled instances have failed.
