Functions

func NewDefaultSCMContext

func NewDefaultSCMContext() *defaultSCMContext

Types

type CACert

type CACert struct {
	SourceURL url.URL
}

CACert implements SCMAuth interface for using a custom certificate authority

func (CACert) Handles

func (_ CACert) Handles(name string) bool

Handles returns true if the secret is a CA certificate

func (CACert) Name

func (_ CACert) Name() string

Name returns the name of this auth method.

func (CACert) Setup

func (s CACert) Setup(baseDir string, context SCMAuthContext) error

Setup creates a .gitconfig fragment that points to the given ca.crt

type GitConfig

type GitConfig struct{}

GitConfig implements SCMAuth interface for using a custom .gitconfig file

func (GitConfig) Handles

func (_ GitConfig) Handles(name string) bool

Handles returns true if the secret file is a gitconfig

func (GitConfig) Name

func (_ GitConfig) Name() string

Name returns the name of this auth method.

func (GitConfig) Setup

func (_ GitConfig) Setup(baseDir string, context SCMAuthContext) error

Setup adds the secret .gitconfig as an include to the .gitconfig file to be used in the build

type SCMAuth

type SCMAuth interface {
	// Name is the name of the authentication method for use in log and error messages
	Name() string

	// Handles returns true if this authentication method handles a file with the given name
	Handles(name string) bool

	// Setup lays down the required files for this authentication method to work.
	// Returns the the source URL stripped of credentials.
	Setup(baseDir string, context SCMAuthContext) error
}

SCMAuth is an interface implemented by different authentication providers which are responsible for setting up the credentials to be used when accessing private repository.

type SCMAuthContext

type SCMAuthContext interface {
	// Get returns the value of a variable if previously set on the context and
	// a boolean indicating whether the variable is set or not
	Get(name string) (string, bool)

	// Set will set the value of a variable. If a variable has already been set
	// and the value sent is different, then an error will be returned.
	Set(name, value string) error

	// SetOverrideURL will set an override URL. If a value has already been set
	// and the URL passed is different, then an error will be returned.
	SetOverrideURL(u *url.URL) error
}

SCMAuthContext keeps track of variables needed for SCM authentication. The variables will then be used to invoke git

type SCMAuths

type SCMAuths []SCMAuth

func GitAuths

func GitAuths(sourceURL *url.URL) SCMAuths

func (SCMAuths) Setup

func (a SCMAuths) Setup(secretsDir string) (env []string, overrideURL *url.URL, err error)

type SSHPrivateKey

type SSHPrivateKey struct{}

SSHPrivateKey implements SCMAuth interface for using SSH private keys.

func (SSHPrivateKey) Handles

func (_ SSHPrivateKey) Handles(name string) bool

Handles returns true if the file is an SSH private key

func (SSHPrivateKey) Name

func (_ SSHPrivateKey) Name() string

Name returns the name of this auth method.

func (SSHPrivateKey) Setup

func (_ SSHPrivateKey) Setup(baseDir string, context SCMAuthContext) error

Setup creates a wrapper script for SSH command to be able to use the provided SSH key while accessing private repository.

type UsernamePassword

type UsernamePassword struct {
	SourceURL url.URL
}

UsernamePassword implements SCMAuth interface for using Username and Password credentials

func (UsernamePassword) Handles

func (_ UsernamePassword) Handles(name string) bool

Handles returns true if a username, password or token secret is present

func (UsernamePassword) Name

func (_ UsernamePassword) Name() string

Name returns the name of this auth method.

func (UsernamePassword) Setup

func (u UsernamePassword) Setup(baseDir string, context SCMAuthContext) error

Setup creates a gitconfig fragment that includes a substitution URL with the username/password included in the URL. Returns source URL stripped of username/password credentials.
