Describes the desired state of a service.

Fields

image: String

An opaque identifier for the executable or container image to run.

Often names a container on Docker Hub or a path on the local machine.

init_container_image: Option<String>

For the Kubernetes orchestrator, this is an init container to configure for the pod running the service.

args: &'a (dyn Fn(&BTreeMap<String, String>) -> Vec<String> + Send + Sync)

A function that generates the arguments for each process of the service given the assigned listen addresses for each named port.

ports: Vec<ServicePort>

Ports to expose.

memory_limit: Option<MemoryLimit>

An optional limit on the memory that the service can use.

cpu_limit: Option<CpuLimit>

An optional limit on the CPU that the service can use.

scale: u16

The number of copies of this service to run.

labels: BTreeMap<String, String>

Arbitrary key–value pairs to attach to the service in the orchestrator backend.

The orchestrator backend may apply a prefix to the key if appropriate.

availability_zone: Option<String>

The availability zone the service should be run in. If no availability zone is specified, the orchestrator is free to choose one.

anti_affinity: Option<Vec<LabelSelector>>

A set of label selectors declaring anti-affinity. If all such selectors match for a given service, this service should not be co-scheduled on a machine with that service.

The orchestrator backend may or may not actually implement anti-affinity functionality.
