Struct DockerConfig 

pub struct DockerConfig {
    pub auths: HashMap<String, DockerCredentials>,
    pub creds_store: Option<String>,
    pub cred_helpers: HashMap<String, String>,
}

Parsed Docker client configuration, loaded from ~/.docker/config.json.

Contains inline credentials and references to external credential helpers. Use DockerConfig::credentials_for_registry to resolve credentials for a specific registry, or DockerConfig::all_credentials to collect credentials for every known registry.

Fields

auths: HashMap<String, DockerCredentials>

Inline credentials from the auths section of config.json, keyed by registry URL or hostname.

creds_store: Option<String>

Global credential store helper name (e.g. "osxkeychain").

cred_helpers: HashMap<String, String>

Per-registry credential helpers, keyed by registry hostname.

Implementations

impl DockerConfig

pub async fn load() -> Result<Self, Error>

Load the Docker configuration from the standard location.

Search order:

1. $DOCKER_CONFIG/config.json (if DOCKER_CONFIG env var is set)
2. ~/.docker/config.json

Returns an empty config if no file is found.

pub fn credentials_for_registry( &self, registry: &str, ) -> Option<DockerCredentials>

Resolve credentials for the given registry, including via external credential helpers (credsStore / credHelpers).

registry may be a hostname (docker.io, gcr.io) or a full URL (https://index.docker.io/v1/). The lookup order is:

1. Per-registry credential helper (credHelpers)
2. Inline auth or identitytoken in the auths section
3. Global credential store (credsStore)

Returns None if no credentials are found or the credential helper fails (e.g. the helper binary is not installed).

pub fn all_credentials(&self) -> HashMap<String, DockerCredentials>

Retrieve credentials for every registry that appears in the auths or credHelpers sections of the config file.

Suitable for populating the X-Registry-Config header used by multi-registry operations such as Docker::build_image.

Each registry is resolved via credentials_for_registry, so credential helpers are invoked as needed. Registries whose helper fails or returns no credentials are silently omitted.
