Functions

func Write

func Write(cfg WriteConfig) (filesWritten []string, err error)

Write writes user credentials to disk in a specified format. It returns the names of the files successfully written.

Types

type ConfigWriter

type ConfigWriter interface {
	// WriteFile writes the given data to path `name`, using the specified
	// permissions if the file is new.
	WriteFile(name string, data []byte, perm os.FileMode) error

	// Remove removes a file.
	Remove(name string) error

	// Stat fetches information about a file.
	Stat(name string) (fs.FileInfo, error)
}

ConfigWriter is a simple filesystem abstraction to allow alternative simple read/write for this package.

type Format

type Format string

Format describes possible file formats how a user identity can be stored.

const (
	// FormatFile is when a key + cert are stored concatenated into a single file
	FormatFile Format = "file"

	// FormatOpenSSH is OpenSSH-compatible format, when a key and a cert are stored in
	// two different files (in the same directory)
	FormatOpenSSH Format = "openssh"

	// FormatTLS is a standard TLS format used by common TLS clients (e.g. GRPC) where
	// certificate and key are stored in separate files.
	FormatTLS Format = "tls"

	// FormatKubernetes is a standard Kubernetes format, with all credentials
	// stored in a "kubeconfig" file.
	FormatKubernetes Format = "kubernetes"

	// FormatDatabase produces CA and key pair suitable for configuring a
	// database instance for mutual TLS.
	FormatDatabase Format = "db"

	// FormatMongo produces CA and key pair in the format suitable for
	// configuring a MongoDB database for mutual TLS authentication.
	FormatMongo Format = "mongodb"

	// FormatCockroach produces CA and key pair in the format suitable for
	// configuring a CockroachDB database for mutual TLS.
	FormatCockroach Format = "cockroachdb"

	// FormatRedis produces CA and key pair in the format suitable for
	// configuring a Redis database for mutual TLS.
	FormatRedis Format = "redis"

	// FormatSnowflake produces public key in the format suitable for
	// configuration Snowflake JWT access.
	FormatSnowflake Format = "snowflake"
	// FormatCassandra produces CA and key pair in the format suitable for
	// configuring a Cassandra database for mutual TLS.
	FormatCassandra Format = "cassandra"
	// FormatScylla produces CA and key pair in the format suitable for
	// configuring a Scylla database for mutual TLS.
	FormatScylla Format = "scylla"

	// FormatElasticsearch produces CA and key pair in the format suitable for
	// configuring Elasticsearch for mutual TLS authentication.
	FormatElasticsearch Format = "elasticsearch"

	// DefaultFormat is what Teleport uses by default
	DefaultFormat = FormatFile
)

type FormatList

type FormatList []Format

FormatList is a list of all possible FormatList.

func (FormatList) String

func (f FormatList) String() string

String returns human-readable version of FormatList, ex: file, openssh, tls, kubernetes

type InMemoryConfigWriter

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

InMemoryConfigWriter is a basic virtual file system abstraction that writes into memory

instead of writing to a more persistent storage.

func NewInMemoryConfigWriter

func NewInMemoryConfigWriter() *InMemoryConfigWriter

NewInMemoryConfigWriter creates a new virtual file system It stores the files contents and their properties in memory

func (*InMemoryConfigWriter) Open

func (m *InMemoryConfigWriter) Open(name string) (fs.File, error)

Open is not implemented but exists here to satisfy the io/fs.ReadFileFS interface.

func (*InMemoryConfigWriter) ReadFile

func (m *InMemoryConfigWriter) ReadFile(name string) ([]byte, error)

ReadFile returns the file contents. Returns fs.ErrNotExists if the file is not present

func (*InMemoryConfigWriter) Remove

func (m *InMemoryConfigWriter) Remove(name string) error

Remove the file. If the file does not exist, Remove is a no-op

func (*InMemoryConfigWriter) Stat

func (m *InMemoryConfigWriter) Stat(name string) (fs.FileInfo, error)

Stat returns the FileInfo of the given file. Returns fs.ErrNotExists if the file is not present

func (*InMemoryConfigWriter) WriteFile

func (m *InMemoryConfigWriter) WriteFile(name string, data []byte, perm os.FileMode) error

WriteFile writes the given data to path `name` It replaces the file if it already exists

type StandardConfigWriter

type StandardConfigWriter struct{}

StandardConfigWriter is a trivial ConfigWriter that wraps the relevant `os` functions.

func (*StandardConfigWriter) Remove

func (s *StandardConfigWriter) Remove(name string) error

Remove removes the named file or (empty) directory. If there is an error, it will be of type *PathError.

func (*StandardConfigWriter) Stat

func (s *StandardConfigWriter) Stat(name string) (fs.FileInfo, error)

Stat returns a FileInfo describing the named file. If there is an error, it will be of type *PathError.

func (*StandardConfigWriter) WriteFile

func (s *StandardConfigWriter) WriteFile(name string, data []byte, perm os.FileMode) error

WriteFile writes data to the named file, creating it if necessary.

type WriteConfig

type WriteConfig struct {
	// OutputPath is the output path for the identity file. Note that some
	// formats (like FormatOpenSSH and FormatTLS) write multiple output files
	// and use OutputPath as a prefix.
	OutputPath string
	// Key contains the credentials to write to the identity file.
	Key *client.Key
	// Format is the output format for the identity file.
	Format Format
	// KubeProxyAddr is the public address of the proxy with its kubernetes
	// port. KubeProxyAddr is only used when Format is FormatKubernetes.
	KubeProxyAddr string
	// KubeTLSServerName is the SNI host value passed to the server.
	KubeTLSServerName string
	// KubeStoreAllCAs stores the CAs of all clusters in kubeconfig, instead
	// of just the root cluster's CA.
	KubeStoreAllCAs bool
	// OverwriteDestination forces all existing destination files to be
	// overwritten. When false, user will be prompted for confirmation of
	// overwrite first.
	OverwriteDestination bool
	// Writer is the filesystem implementation.
	Writer ConfigWriter
	// JKSPassword is the password for the JKS keystore used by Cassandra format.
	JKSPassword string
}

WriteConfig holds the necessary information to write an identity file.
