Struct FilesystemDockerfileEnvironment 

pub struct FilesystemDockerfileEnvironment {
    pub build_args: BTreeMap<String, String>,
}

A DockerfileEnvironment that reads the Dockerfile straight off disk — the one production side effect this crate performs beyond the command runner and the cache backend.

Fields

build_args: BTreeMap<String, String>

Trait Implementations

impl DockerfileEnvironment for FilesystemDockerfileEnvironment

fn read_dockerfile(&self, path: &str) -> Result<String, String>

Read the Dockerfile at path. In the canonical-instance path the “path” is just the spec’s name and the text comes from the authored spec itself; a real consumer wraps std::fs::read_to_string.

fn resolve_build_arg(&self, name: &str) -> Option<String>

Resolve a build-arg’s value from the environment (e.g. --build-arg TARGETARCH=amd64). Returns None on miss — the interpreter falls back to the ARG’s declared default, or leaves it unresolved if neither exists.
