Request body for POST /api/v1/containers/{id}/update.

Mirrors Docker Engine’s POST /containers/{id}/update body 1:1 so the zlayer-docker compatibility shim can pass the wire payload straight through. Every field is optional — only the fields present on the wire are applied; unset fields are left untouched on the running container.

Field naming uses Docker’s PascalCase on the wire (CpuShares, Memory, …) and snake_case on the Rust side. Subset of the full Docker schema: ZLayer supports the resource knobs (cpu, memory, pids, blkio) plus RestartPolicy. Windows-only fields (CpuCount, IOMaximumIOps) and ulimits/devices are accepted on the wire but silently ignored by the Linux runtimes.

Fields

cpu_shares: Option<i64>

Relative CPU weight (cgroup cpu.weight or cpu.shares). Range 2-262144 on cgroup v2; 2-262144 mapped from 1-10000 on v1.

memory: Option<i64>

Memory limit in bytes. Set 0 to remove the limit.

cpu_period: Option<i64>

CPU CFS period in microseconds.

cpu_quota: Option<i64>

CPU CFS quota in microseconds. Together with cpu_period defines the fraction of a CPU the container may use.

cpu_realtime_period: Option<i64>

CPU real-time period in microseconds.

cpu_realtime_runtime: Option<i64>

CPU real-time runtime in microseconds.

cpuset_cpus: Option<String>

CPUs allowed for execution (e.g. "0-3", "0,1").

cpuset_mems: Option<String>

Memory nodes (NUMA) allowed for execution (e.g. "0-3").

memory_reservation: Option<i64>

Soft memory limit in bytes. The kernel reclaims pages above this reservation when the host comes under memory pressure.

memory_swap: Option<i64>

Total memory limit (memory + swap) in bytes. -1 removes the swap limit, matching Docker semantics.

kernel_memory: Option<i64>

Kernel memory limit in bytes (deprecated upstream; accepted for wire compatibility).

blkio_weight: Option<u16>

Block IO weight (relative weight, range 10-1000).

pids_limit: Option<i64>

PIDs limit. Set 0 or -1 for unlimited.

restart_policy: Option<ContainerUpdateRestartPolicy>

New restart policy. When present, replaces the container’s stored restart policy. Docker applies this asynchronously: the next time the supervisor decides whether to restart, it consults the new policy.

Trait Implementations

impl Clone for ContainerUpdateRequest

fn clone(&self) -> ContainerUpdateRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ComposeSchema for ContainerUpdateRequest

fn compose(generics: Vec<RefOr<Schema>>) -> RefOr<Schema>

impl Debug for ContainerUpdateRequest

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

Formats the value using the given formatter.

impl Default for ContainerUpdateRequest

fn default() -> ContainerUpdateRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ContainerUpdateRequest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ContainerUpdateRequest

fn eq(&self, other: &ContainerUpdateRequest) -> 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 ContainerUpdateRequest

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSchema for ContainerUpdateRequest

fn name() -> Cow<'static, str>

Return name of the schema.

fn schemas(schemas: &mut Vec<(String, RefOr<Schema>)>)

Implement reference utoipa::openapi::schema::Schemas for this type.

impl Eq for ContainerUpdateRequest

impl StructuralPartialEq for ContainerUpdateRequest
