Functions

func LoadConfig

func LoadConfig(path string, v *Config) error

LoadConfig loads the containerd server config from the provided path

Types

type CgroupConfig

type CgroupConfig struct {
	Path string `toml:"path"`
}

CgroupConfig provides cgroup configuration

type Config

type Config struct {
	// Root is the path to a directory where containerd will store persistent data
	Root string `toml:"root"`
	// State is the path to a directory where containerd will store transient data
	State string `toml:"state"`
	// GRPC configuration settings
	GRPC GRPCConfig `toml:"grpc"`
	// Debug and profiling settings
	Debug Debug `toml:"debug"`
	// Metrics and monitoring settings
	Metrics MetricsConfig `toml:"metrics"`
	// Plugins provides plugin specific configuration for the initialization of a plugin
	Plugins map[string]toml.Primitive `toml:"plugins"`
	// Enable containerd as a subreaper
	Subreaper bool `toml:"subreaper"`
	// OOMScore adjust the containerd's oom score
	OOMScore int `toml:"oom_score"`
	// Cgroup specifies cgroup information for the containerd daemon process
	Cgroup CgroupConfig `toml:"cgroup"`
	// contains filtered or unexported fields
}

Config provides containerd configuration data for the server

func (*Config) Decode

func (c *Config) Decode(id string, v interface{}) (interface{}, error)

Decode unmarshals a plugin specific configuration by plugin id

func (*Config) WriteTo

func (c *Config) WriteTo(w io.Writer) (int64, error)

WriteTo marshals the config to the provided writer

type Debug

type Debug struct {
	Address string `toml:"address"`
	UID     int    `toml:"uid"`
	GID     int    `toml:"gid"`
	Level   string `toml:"level"`
}

type GRPCConfig struct {
	Address string `toml:"address"`
	UID     int    `toml:"uid"`
	GID     int    `toml:"gid"`
}

GRPCConfig provides GRPC configuration for the socket

type MetricsConfig

type MetricsConfig struct {
	Address string `toml:"address"`
}

MetricsConfig provides metrics configuration

type Server

type Server struct {
	// contains filtered or unexported fields
}

Server is the containerd main daemon
