[]

Kubernetes YAML configs for extra container volume(s). Any volumes required by other config options are automatically handled by the Helm chart.

int

1

The number of Knative requests that can be handled simultaneously by one container

string

None, must be set

Topic where raw image arrival notifications appear

prompt-proto-service.instrument.calibRepo

string

""

The “short” name of the instrument

prompt-proto-service.instrument.pipelines.main

string

None, must be set

YAML-formatted config describing which pipeline(s) should be run for which visits’ raws. Fields are still in flux; see the source code for examples.

prompt-proto-service.instrument.pipelines.preprocessing

string

None, must be set

YAML-formatted config describing which pipeline(s) should be run before which visits’ raw arrival.

prompt-proto-service.knative.cpuLimit

int

1

The maximum cpu cores for the full pod (see containerConcurrency).

prompt-proto-service.knative.gpuRequest

int

0

The number of GPUs to request for the full pod (see containerConcurrency).

prompt-proto-service.knative.idleTimeout

int

prompt-proto-service.knative.memoryRequest

string

"2Gi"

The minimum memory to request for the full pod (see containerConcurrency).

prompt-proto-service.knative.responseStartTimeout

int

0

Maximum time that a container can send nothing to Knative after initial submission (seconds). This is only useful if the container runs async workers. If 0, idle timeout is ignored.

prompt-proto-service.s3.imageBucket

string

None, must be set

Bucket containing the incoming raw images
