Struct isolated::Process

pub struct Process { /* fields omitted */ }

Offers an API similar to std::process::Child. When dropping, attempts termination and cleanup.

Implementations

impl Process

pub fn spawn<L: AsRef<Path>, W: AsRef<Path>>(
    path: &str,
    args: &[&str],
    layers: &[L],
    writedir: Option<W>,
    pre_pivot: Option<fn() -> Result<()>>,
    pre_exec: Option<fn() -> Result<()>>
) -> Result<Process>

Spawns a new process from path with args. layers specify overlayfs layers from outermost to innermost, usually [rootfs, appdir] where rootfs contains a linux root file system like Alpine minirootfs, and appdir is the directory where the application binary is located. All of the layers are overlayed on the root of the container file system. writedir is a directory containing modifications to the file system done by the application. If it is None, then a temporary directory is used instead.

pre_exec, if given, is a closure to be execute after for

TODO: Document restrictions

pub fn wait(&mut self) -> Result<WaitStatus>

Wait until the process completes, and return it’s status.

pub fn signal(&mut self, signal: Signal) -> Result<()>

Send a signal to the process. Panics if wait has returned succesfully before.
