Per-service specification

Fields

rtype: ResourceType

Resource type (service, job, cron)

schedule: Option<String>

Cron schedule expression (only for rtype: cron) Uses 7-field cron syntax: “sec min hour day-of-month month day-of-week year” Examples:

• “0 0 0 * * * *” (daily at midnight)
• “0 */5 * * * * *” (every 5 minutes)
• “0 0 12 * * MON-FRI *” (weekdays at noon)

image: ImageSpec

Container image specification

resources: ResourcesSpec

Resource limits

env: HashMap<String, String>

Environment variables for the service

Values can be:

• Plain strings: "value"
• Host env refs: $E:VAR_NAME
• Secret refs: $S:secret-name or $S:@service/secret-name

command: CommandSpec

Command override (entrypoint, args, workdir)

network: NetworkSpec

Network configuration

endpoints: Vec<EndpointSpec>

Endpoint definitions (proxy bindings)

scale: ScaleSpec

Scaling configuration

depends: Vec<DependsSpec>

Dependency specifications

health: HealthSpec

Health check configuration

init: InitSpec

Init actions (pre-start lifecycle steps)

errors: ErrorsSpec

Error handling policies

devices: Vec<DeviceSpec>

Device passthrough (e.g., /dev/kvm for VMs)

storage: Vec<StorageSpec>

Storage mounts for the container

capabilities: Vec<String>

Linux capabilities to add (e.g., SYS_ADMIN, NET_ADMIN)

privileged: bool

Run container in privileged mode (all capabilities + all devices)

node_mode: NodeMode

Node allocation mode (shared, dedicated, exclusive)

node_selector: Option<NodeSelector>

Node selection constraints (required/preferred labels)

service_type: ServiceType

Service type (standard, wasm_http, job)

wasm_http: Option<WasmHttpConfig>

WASM HTTP configuration (only used when service_type is WasmHttp)

host_network: bool

Use host networking (container shares host network namespace)

When true, the container will NOT get its own network namespace. This is set programmatically via the --host-network CLI flag, not in YAML specs.

Trait Implementations

impl Clone for ServiceSpec

fn clone(&self) -> ServiceSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ServiceSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ServiceSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ServiceSpec

fn eq(&self, other: &ServiceSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ServiceSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Validate for ServiceSpec

fn validate(&self) -> Result<(), ValidationErrors>

impl<'v_a> ValidateArgs<'v_a> for ServiceSpec

type Args = ()

fn validate_with_args(&self, args: Self::Args) -> Result<(), ValidationErrors>

impl StructuralPartialEq for ServiceSpec
