Struct SshTunnel 

pub struct SshTunnel { /* private fields */ }

SSH tunnel to a remote Docker daemon

The tunnel forwards a local port to the remote Docker socket. Implements Drop to ensure the SSH process is killed on cleanup.

Implementations

impl SshTunnel

pub fn new(host: &HostConfig, host_name: &str) -> Result<Self, HostError>

Create SSH tunnel to remote Docker socket

Spawns an SSH process with local port forwarding: ssh -L local_port:/var/run/docker.sock -N host

Uses BatchMode=yes to fail fast if key not in agent.

pub fn local_port(&self) -> u16

Get the local port for Docker connection

pub fn docker_url(&self) -> String

Get the Docker connection URL

pub fn host_name(&self) -> &str

Get the host name this tunnel connects to

pub async fn wait_ready(&self) -> Result<(), HostError>

Wait for tunnel to be ready (port accepting connections)

Retries with exponential backoff: 100ms, 200ms, 400ms (3 attempts)

pub fn is_alive(&mut self) -> bool

Check if the SSH process is still running

Trait Implementations

impl Drop for SshTunnel

fn drop(&mut self)

Executes the destructor for this type.
