Struct ApptainerConfig 

pub struct ApptainerConfig {
    pub executable: String,
    pub image_cache_dir: Option<PathBuf>,
    pub extra_apptainer_exec_args: Option<Vec<String>>,
}

Configuration for the Apptainer container runtime.

Fields

executable: String

Path to the Apptainer (or Singularity) executable.

Defaults to "apptainer". Set to "singularity" or a full path (e.g., /usr/local/bin/apptainer) if the executable is not on PATH or if using Singularity instead.

image_cache_dir: Option<PathBuf>

Path to a shared directory for caching pulled .sif images.

When set, pulled images are stored in this directory and shared across runs. When unset, images are stored in a per-run directory that is not shared.

extra_apptainer_exec_args: Option<Vec<String>>

Additional command-line arguments to pass to apptainer exec when executing tasks.
