pub async fn pull_image(
cli: &str,
docker_config: Option<&Path>,
reference: &str,
) -> Result<PulledImage, String>Expand description
Pull reference with the container cli. A transient registry failure
falls back to a locally cached copy, or is retried with backoff when
nothing is cached; any other failure is returned at once. docker_config
is exported as DOCKER_CONFIG for the pull so registry credentials
resolve.
Returns the pull’s stderr as the error.
