Struct wasmcloud_host::HostManifest

pub struct HostManifest { /* fields omitted */ }

A host manifest contains a declarative profile of the host’s desired state. The manifest can specify custom labels, a list of actors, a list of capability providers, and a list of link definitions. Environment substitution syntax can optionally be used within a manifest file so that information that may change across environments (like public keys) can change without requiring the manifest file to change.

Examples

labels:
    sample: "wasmcloud echo"
actors:
    - "wasmcloud.azurecr.io/echo:0.2.0"
capabilities:
    - image_ref: wasmcloud.azurecr.io/httpserver:0.11.1
      link_name: default
links:
    - actor: ${ECHO_ACTOR:MBCFOPM6JW2APJLXJD3Z5O4CN7CPYJ2B4FTKLJUR5YR5MITIU7HD3WD5}
      provider_id: "VAG3QITQQ2ODAOWB5TTQSDJ53XK3SHBEIFNK4AYJ5RKAX2UNSCAPHA5M"
      contract_id: "wasmcloud:httpserver"
      link_name: default
      values:
        PORT: 8080

Implementations

impl HostManifest

pub fn from_path(
    path: impl AsRef<Path>,
    expand_env: bool
) -> Result<HostManifest, Box<dyn Error + Send + Sync>>

Creates an instance of a host manifest from a file path. The de-serialization type will be chosen based on the file path extension, selecting YAML for .yaml or .yml files, and JSON for all other file extensions. If the path has no extension, the de-serialization type chosen will be YAML. If expand_env is true then environment substitution syntax will be honored in the manifest file.
