Constants ¶
const ( DockerDesktopEmail = "DOCKER_EMAIL" DockerDesktopUsername = "DOCKER_USERNAME" DockerDesktopTokenEnv = "DOCKER_TOKEN" )
const SandboxTokensFileName = "sandbox-tokens.json"
SandboxTokensFileName is the name of the JSON file used to forward short-lived tokens (e.g. DOCKER_TOKEN) from the host into a Docker sandbox. The host writes this file periodically; the sandbox reads it.
Variables ¶

Functions ¶
func AbsolutePath ¶
func InSandbox ¶
func InSandbox() bool
InSandbox reports whether docker agent is running inside a Docker sandbox. Detection relies on the SANDBOX_VM_ID environment variable that Docker Desktop sets in every sandbox VM.
func SandboxTokensFilePath ¶
SandboxTokensFilePath returns the absolute path to the sandbox tokens file inside the given directory.
Types ¶
type CredentialHelperProvider ¶
type CredentialHelperProvider struct {
// contains filtered or unexported fields
}
CredentialHelperProvider retrieves Docker credentials using an external CLI command configured in the user's global config file.
func NewCredentialHelperProvider ¶
func NewCredentialHelperProvider(command string, args ...string) *CredentialHelperProvider
NewCredentialHelperProvider creates a new CredentialHelperProvider instance. The command parameter is the shell command to execute to retrieve the Docker token.
type DockerDesktopProvider ¶
type DockerDesktopProvider struct{}
func NewDockerDesktopProvider ¶
func NewDockerDesktopProvider() *DockerDesktopProvider
type EnvFilesProvider ¶
type EnvFilesProvider struct {
// contains filtered or unexported fields
}
EnvFilesProvider provides access env files.
func NewEnvFilesProvider ¶
func NewEnvFilesProvider(absEnvFiles []string) (*EnvFilesProvider, error)
type EnvListProvider ¶
type EnvListProvider struct {
// contains filtered or unexported fields
}
EnvListProvider provides access a list of environment variables.
func NewEnvListProvider ¶
func NewEnvListProvider(env []string) *EnvListProvider
type KeyValuePair ¶
func ReadEnvFile ¶
func ReadEnvFile(absolutePath string) ([]KeyValuePair, error)
func ReadEnvFiles ¶
func ReadEnvFiles(absolutePaths []string) ([]KeyValuePair, error)
type KeychainNotAvailableError ¶
type KeychainNotAvailableError struct{}
func (KeychainNotAvailableError) Error ¶
func (KeychainNotAvailableError) Error() string
type KeychainProvider ¶
type KeychainProvider struct{}
KeychainProvider is a provider that retrieves secrets using the macOS keychain via the `security` command-line tool.
func NewKeychainProvider ¶
func NewKeychainProvider() (*KeychainProvider, error)
NewKeychainProvider creates a new KeychainProvider instance. It verifies that the `security` command is available on the system.
type MultiProvider ¶
type MultiProvider struct {
// contains filtered or unexported fields
}
func NewMultiProvider ¶
func NewMultiProvider(providers ...Provider) *MultiProvider
type OsEnvProvider ¶
type OsEnvProvider struct{}
OsEnvProvider provides access to the operating system's environment variables.
func NewOsEnvProvider ¶
func NewOsEnvProvider() *OsEnvProvider
type PassNotAvailableError ¶
type PassNotAvailableError struct{}
func (PassNotAvailableError) Error ¶
func (PassNotAvailableError) Error() string
type PassProvider ¶
type PassProvider struct{}
PassProvider is a provider that retrieves secrets using the `pass` password manager.
func NewPassProvider ¶
func NewPassProvider() (*PassProvider, error)
NewPassProvider creates a new PassProvider instance.
type Provider ¶
type Provider interface {
// Get retrieves the value of an environment variable by name.
// Returns (value, true) if found (value may be empty).
// Returns ("", false) if not found.
Get(ctx context.Context, name string) (string, bool)
}
func NewDefaultProvider ¶
func NewDefaultProvider() Provider
NewDefaultProvider creates a provider chain with OS env, run secrets, credential helper (if configured), Docker Desktop, pass, and keychain providers.
When running inside a Docker sandbox (detected via SANDBOX_VM_ID), a SandboxTokenProvider is prepended so that DOCKER_TOKEN is read from the JSON file written by the host-side token writer.
type RequiredEnvError ¶
type RequiredEnvError struct {
Missing []string
}
func (*RequiredEnvError) Error ¶
func (e *RequiredEnvError) Error() string
type RunSecretsProvider ¶
type RunSecretsProvider struct {
// contains filtered or unexported fields
}
func NewRunSecretsProvider ¶
func NewRunSecretsProvider() *RunSecretsProvider
type SandboxTokenProvider ¶
type SandboxTokenProvider struct {
// contains filtered or unexported fields
}
SandboxTokenProvider reads DOCKER_TOKEN from a JSON file on disk. It is used inside the sandbox where Docker Desktop's backend API is unreachable and the OS env contains only a stale one-shot token.
Only DOCKER_TOKEN is served; requests for any other variable return ("", false).
func NewSandboxTokenProvider ¶
func NewSandboxTokenProvider(path string) *SandboxTokenProvider
NewSandboxTokenProvider creates a provider that reads tokens from path.
type SandboxTokenWriter ¶
type SandboxTokenWriter struct {
// contains filtered or unexported fields
}
SandboxTokenWriter periodically fetches DOCKER_TOKEN from a provider and writes it to the sandbox tokens JSON file so that processes inside the sandbox can read a fresh value.
func NewSandboxTokenWriter ¶
func NewSandboxTokenWriter(path string, provider Provider, interval time.Duration) *SandboxTokenWriter
NewSandboxTokenWriter creates a writer that refreshes the token file at the given interval. Call SandboxTokenWriter.Start to begin writing and SandboxTokenWriter.Stop to terminate the background goroutine.
func (*SandboxTokenWriter) Start ¶
func (w *SandboxTokenWriter) Start(ctx context.Context)
Start writes the token file immediately and then refreshes it on the configured interval in a background goroutine.
func (*SandboxTokenWriter) Stop ¶
func (w *SandboxTokenWriter) Stop()
Stop terminates the background goroutine and removes the token file.
