Struct ContainerSpec 

pub struct ContainerSpec {
    pub name: String,
    pub image: String,
    pub env: Vec<(String, String)>,
    pub command: Option<Vec<String>>,
    pub ports: Vec<PortBinding>,
    pub mounts: Vec<FileMount>,
    pub network_id: Option<String>,
    pub aliases: Vec<String>,
    pub run_id: String,
    pub memory_limit_mb: Option<u64>,
}

Everything a backend needs to create one container. Host ports in ports are already chosen by the core allocator (see free_ports) — a backend binds them, it never allocates, so the same spec works identically whether the backend is a microVM or a Docker daemon.

Fields

name: String

The backend-facing container name, e.g. rz-<run_id>-<seq>.

image: String

The image reference to run.

env: Vec<(String, String)>

Environment variables, insertion-ordered — a Vec of pairs rather than a HashMap so order and duplicate-key handling stay under the caller’s control.

command: Option<Vec<String>>

The command to run instead of the image’s default entrypoint. None means “run the image as built.”

ports: Vec<PortBinding>

Already-chosen host↔guest port bindings — see the type-level doc.

mounts: Vec<FileMount>

Host files/directories to mount into the guest.

network_id: Option<String>

The network to join, if any.

aliases: Vec<String>

DNS-style aliases this container is reachable as by other members of its network.

run_id: String

The per-process run id (see run_id), used to label/name containers so a crashed run’s leftovers can be told apart from a live run’s.

memory_limit_mb: Option<u64>

An optional memory cap in megabytes.

Implementations

impl ContainerSpec

pub fn new( name: impl Into<String>, image: impl Into<String>, run_id: impl Into<String>, ) -> Self

Builds a spec with every optional field at its default (no env, no command, no ports, no mounts, no network, no aliases, no memory limit).

Trait Implementations

impl Clone for ContainerSpec

fn clone(&self) -> ContainerSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContainerSpec

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

Formats the value using the given formatter.
