Local Artifacts
When running wasmCloud locally using wash up, it's simple to deploy applications using local file references. This enables rapid iteration and testing of applications during development, by not having to push and pull artifacts to a registry. In a production environment, however, deploying artifacts from a filesystem is not always wise, as local artifacts are not immutable and may be tampered with.
Fortunately, the wasmCloud host denies requests to start actors and providers from local artifacts by default.
When using wash up for local development, wash overrides this behavior and enables loading from file references, via the --allow-file-load option on the host. If for some reason it is necessary to start from a file reference in production, this option can be enabled.
