Isolation

Enum Isolation 

Source
pub enum Isolation {
    None {},
    Worktree {},
    Container {
        image: Option<String>,
        network: bool,
    },
}
Expand description

How much of the machine a node is kept away from.

The ladder is real but not linear in cost: Worktree is nearly free and is what makes parallel writers safe, while Container buys filesystem and network separation at the price of a Docker daemon and an image pull.

Container degrades rather than fails. If Docker is not present the node runs under Worktree and the run records a warning — a config written on a machine with Docker must still work on one without, because the same loop directory gets checked out on developer laptops, CI runners and servers, and refusing to start there would make container isolation unusable in practice rather than merely unavailable.

Variants§

§

None

Runs directly in the loop directory. Correct for a single writer or a read-only node.

§

Worktree

Runs in its own git worktree, published back on success. Required for parallel writers.

§

Container

Runs in a container over its own worktree.

Fields

§image: Option<String>

Image to run in. Defaults to the loop-wide image when unset.

§network: bool

Allow the container to reach the network. Off by default: a node that does not need the network should not have it.

Implementations§

Source§

impl Isolation

Source

pub fn needs_worktree(&self) -> bool

Whether this node needs a worktree of its own. Container isolation implies one, because the container mounts it.

Source

pub fn is_container(&self) -> bool

What this becomes when Docker is unavailable.

Source

pub fn container_image<'a>( &'a self, graph_default: Option<&'a str>, ) -> Option<&'a str>

The image a container node runs in: its own, or the graph’s default. None for a non-container node, or when neither names one.

pub fn without_container(&self) -> Isolation
