Functions

func ParseAuth

func ParseAuth(auth *runtime.AuthConfig, host string) (string, string, error)

ParseAuth parses AuthConfig and returns username and password/secret required by containerd. Ported from https://github.com/containerd/containerd/blob/v1.5.2/pkg/cri/server/image_pull.go#L176-L214 TODO: import this from CRI package once we drop support to continerd v1.4.x

func RegistryHostsFromCRIConfig

func RegistryHostsFromCRIConfig(ctx context.Context, config Registry, credsFuncs ...Credential) source.RegistryHosts

RegistryHostsFromCRIConfig creates RegistryHosts (a set of registry configuration) from CRI-plugin-compatible config. NOTE: ported from https://github.com/containerd/containerd/blob/v1.5.2/pkg/cri/server/image_pull.go#L332-L405 TODO: import this from CRI package once we drop support to continerd v1.4.x

func RegistryHostsFromConfig

func RegistryHostsFromConfig(cfg Config, credsFuncs ...Credential) source.RegistryHosts

RegistryHostsFromConfig creates RegistryHosts (a set of registry configuration) from Config.

Types

type AuthConfig

type AuthConfig struct {
	// Username is the username to login the registry.
	Username string `toml:"username" json:"username"`
	// Password is the password to login the registry.
	Password string `toml:"password" json:"password"`
	// Auth is a base64 encoded string from the concatenation of the username,
	// a colon, and the password.
	Auth string `toml:"auth" json:"auth"`
	// IdentityToken is used to authenticate the user and get
	// an access token for the registry.
	IdentityToken string `toml:"identitytoken" json:"identitytoken"`
}

AuthConfig contains the config related to authentication to a specific registry

type Config

type Config struct {
	Host map[string]HostConfig `toml:"host"`
}

Config is config for resolving registries.

type Credential

type Credential func(string, reference.Spec) (string, string, error)

type HostConfig

type HostConfig struct {
	Mirrors []MirrorConfig `toml:"mirrors"`
}

type Mirror

type Mirror struct {
	// Endpoints are endpoints for a namespace. CRI plugin will try the endpoints
	// one by one until a working one is found. The endpoint must be a valid url
	// with host specified.
	// The scheme, host and path from the endpoint URL will be used.
	Endpoints []string `toml:"endpoint" json:"endpoint"`
}

Mirror contains the config related to the registry mirror

type MirrorConfig

type MirrorConfig struct {

	// Host is the hostname of the host.
	Host string `toml:"host"`

	// Insecure is true means use http scheme instead of https.
	Insecure bool `toml:"insecure"`

	// RequestTimeoutSec is timeout seconds of each request to the registry.
	// RequestTimeoutSec == 0 indicates the default timeout (defaultRequestTimeoutSec).
	// RequestTimeoutSec < 0 indicates no timeout.
	RequestTimeoutSec int `toml:"request_timeout_sec"`
}

type Registry

type Registry struct {
	// ConfigPath is a path to the root directory containing registry-specific
	// configurations.
	// If ConfigPath is set, the rest of the registry specific options are ignored.
	ConfigPath string `toml:"config_path" json:"configPath"`
	// Mirrors are namespace to mirror mapping for all namespaces.
	// This option will not be used when ConfigPath is provided.
	// DEPRECATED: Use ConfigPath instead. Remove in containerd 1.7.
	Mirrors map[string]Mirror `toml:"mirrors" json:"mirrors"`
	// Configs are configs for each registry.
	// The key is the domain name or IP of the registry.
	// This option will be fully deprecated for ConfigPath in the future.
	Configs map[string]RegistryConfig `toml:"configs" json:"configs"`
}

Registry is registry settings configured

type RegistryConfig

type RegistryConfig struct {
	// Auth contains information to authenticate to the registry.
	Auth *AuthConfig `toml:"auth" json:"auth"`
	// TLS is a pair of CA/Cert/Key which then are used when creating the transport
	// that communicates with the registry.
	// This field will not be used when ConfigPath is provided.
	// DEPRECATED: Use ConfigPath instead. Remove in containerd 1.7.
	TLS *TLSConfig `toml:"tls" json:"tls"`
}

RegistryConfig contains configuration used to communicate with the registry.

type TLSConfig

type TLSConfig struct {
	InsecureSkipVerify bool   `toml:"insecure_skip_verify" json:"insecure_skip_verify"`
	CAFile             string `toml:"ca_file" json:"caFile"`
	CertFile           string `toml:"cert_file" json:"certFile"`
	KeyFile            string `toml:"key_file" json:"keyFile"`
}

TLSConfig contains the CA/Cert/Key used for a registry
