Struct Config 

pub(crate) struct Config {
    version: Option<Verbosity>,
    version_json: Option<Verbosity>,
    log_level: LogLevel,
    log_driver: LogDriver,
    runtime: PathBuf,
    runtime_dir: PathBuf,
    runtime_root: Option<PathBuf>,
    skip_fork: bool,
    enable_tracing: bool,
    tracing_endpoint: String,
}

A pod level OCI container runtime monitor, started by a container engine like CRI-O.

Fields

version: Option<Verbosity>

Show version information, specify “full” for verbose output.

version_json: Option<Verbosity>

Show version information as parsable JSON, specify “full” for verbose output.

log_level: LogLevel

The logging level of the server.

log_driver: LogDriver

The logging driver used by the server.

runtime: PathBuf

Binary path of the OCI runtime to use to operate on the containers. Required to run the server.

runtime_dir: PathBuf

Path of the directory for conmonrs to hold files at runtime. Required to run the server.

runtime_root: Option<PathBuf>

Root directory used by the OCI runtime to operate on containers, passed to it as --root.

skip_fork: bool

Stay in the foreground instead of forking into the background.

enable_tracing: bool

Enable OpenTelemetry tracing. Builds without the tracing feature ignore it with a warning.

tracing_endpoint: String

OpenTelemetry gRPC endpoint to be used for tracing. Builds without the tracing feature ignore it.

Implementations

impl Config

pub(crate) fn version(&self) -> Option<Verbosity>

Show version information.

pub(crate) fn version_json(&self) -> Option<Verbosity>

Show version information as JSON.

pub(crate) fn log_level(&self) -> LogLevel

The logging level.

pub(crate) fn log_driver(&self) -> LogDriver

The logging driver.

pub(crate) fn runtime(&self) -> &Path

Binary path of the OCI runtime.

pub(crate) fn runtime_is_crun(&self) -> bool

Whether the runtime is crun, which gets arguments of its own, see GenerateRuntimeArgs::default_args.

pub(crate) fn runtime_dir(&self) -> &Path

Path of the directory for conmonrs to hold files at runtime.

pub(crate) fn runtime_root(&self) -> Option<&Path>

Root directory used by the OCI runtime.

pub(crate) fn skip_fork(&self) -> bool

Stay in the foreground instead of forking into the background.

pub(crate) fn enable_tracing(&self) -> bool

Enable OpenTelemetry tracing.

pub(crate) fn tracing_endpoint(&self) -> &str

OpenTelemetry gRPC endpoint.

impl Config

pub(crate) fn parse_args() -> Self

Parse the configuration from the command line and the environment.

impl Config

pub(crate) fn validate(&self) -> Result<()>

Validate the configuration integrity.

pub(crate) fn make_absolute(&mut self) -> Result<()>

Make the paths absolute, the server changes into the root directory once it started, see Server::start.

pub(crate) fn prepare(&self) -> Result<()>

Create the runtime directories and remove stale sockets. Separate from Config::validate, which only checks and changes nothing on disk.

fn socket_in_use(path: &Path) -> Result<bool>

Whether a server accepts connections on the socket. The connect does not wait for a server which does not accept them in time, a full backlog counts as in use as well. A socket of a server which exited is not in use, also if a process left behind still holds it.

fn peer_running(fd: &impl AsFd) -> bool

Whether the process which listens on the other end of a connection still runs, true if that cannot be told.

pub(crate) fn socket(&self) -> PathBuf

The socket the server serves the RPCs on.

pub(crate) fn conmon_pidfile(&self) -> PathBuf

The PID file the parent writes for the forked server.

Trait Implementations

impl Args for Config
