)

Functions

func Delete 

func Delete() error

Delete removes ~/.volcano/config.json. A missing file is considered success.

func FirstPartyDeviceClientID 

func FirstPartyDeviceClientID() (string, error)

FirstPartyDeviceClientID resolves the first-party OAuth device client ID.

func FunctionAliasScope added in v0.0.4 

func FunctionAliasScope(apiURL, projectID string) string

FunctionAliasScope returns the config key for aliases bound to one API URL and project ID. The API URL is trimmed so trailing slashes do not split scopes.

func IsLoopbackAPIURL added in v0.2.0 

func IsLoopbackAPIURL(apiURL string) bool

IsLoopbackAPIURL reports whether apiURL points at a loopback address ("localhost" or a loopback IP). Shared by local-mode's device-client selection and by deriveWebURL below.

func IsProjectToken added in v0.31.0 

func IsProjectToken(token string) bool

IsProjectToken reports whether token is a project access token.

Case-insensitive on purpose. The unknown-prefix default is deliberately fail-open, for credentials minted before the prefixes existed, but "PT-" is not one of those — it is a mangled pt- token, and matching case-sensitively let it past every guard here and fail as an opaque server error instead.

func Path 

func Path() (string, error)

Path returns the default on-disk config path.

func Update added in v0.25.0 

func Update(mutate func(*Config) (bool, error)) error

Update locks, reloads, and conditionally saves the config.

Types

type Config 

type Config struct {
	// APIBaseURL overrides the compiled API URL for synthetic command configs.
	// It is intentionally not persisted to the user's cloud config file.
	APIBaseURL     string         `json:"-"`
	UserToken      string         `json:"user_token,omitempty"`
	UserID         string         `json:"user_id,omitempty"`
	AnonKey        string         `json:"-"`
	ServiceKey     string         `json:"-"`
	CurrentProject *ProjectConfig `json:"current_project,omitempty"`
	// FunctionAliases stores per-user function invoke aliases by API URL and
	// project ID scope. Scope keys are produced by FunctionAliasScope.
	FunctionAliases map[string]map[string]string `json:"function_aliases,omitempty"`
	// DocsSource persists a non-default documentation source override so that
	// `volcano docs` commands resolve the same repo/ref/path across invocations
	// without repeating --repo/--ref/--path flags. Nil means "use the compiled
	// default source".
	DocsSource *DocsSourceConfig `json:"docs_source,omitempty"`
	// IgnoreEnv disables environment overrides for synthetic command configs.
	IgnoreEnv bool `json:"-"`
}

Config represents the CLI configuration stored in ~/.volcano/config.json.

func Default 

func Default() *Config

Default returns an empty config.

func Load 

func Load() (*Config, error)

Load reads ~/.volcano/config.json. Missing config is not an error.

func (*Config) APIURL 

func (c *Config) APIURL() string

APIURL returns the API URL with VOLCANO_API_URL taking precedence unless env overrides are disabled. Precedence: env > runtime override (APIBaseURL) > compiled default.

func (*Config) DeleteFunctionAlias added in v0.0.4 

func (c *Config) DeleteFunctionAlias(scope, alias string) bool

DeleteFunctionAlias removes alias from the given scope and reports whether it existed.

func (*Config) FunctionAlias added in v0.0.4 

func (c *Config) FunctionAlias(scope, alias string) (string, bool)

FunctionAlias returns the function ID configured for alias in the given scope.

func (*Config) FunctionInvokeToken added in v0.0.4 

func (c *Config) FunctionInvokeToken() string

FunctionInvokeToken returns the token used for runtime function invocation. Cloud uses the reserved data-plane service key (via the invoke token provider) or falls back to the configured token. In local mode the session layer sends no credential at all (see session.Factory.APIClient), so this value is unused there.

func (*Config) ProjectID 

func (c *Config) ProjectID() string

ProjectID returns the current project ID, with VOLCANO_PROJECT_ID taking precedence unless env overrides are disabled.

func (*Config) ProjectIDFromEnv added in v0.31.0 

func (c *Config) ProjectIDFromEnv() string

ProjectIDFromEnv returns VOLCANO_PROJECT_ID alone, without the project a previous 'volcano use' saved. Callers that have to tell the two apart — a failure that names the project it ran against — need the distinction.

Trimmed for the same reason as Token: this is the documented CI path, where the value is as likely to arrive with a trailing newline, and untrimmed it failed UUID parsing as "invalid UUID length: 37".

func (*Config) RequireAccountToken added in v0.31.0 

func (c *Config) RequireAccountToken() error

RequireAccountToken rejects a project access token on a command that needs account-wide access. Any other credential is treated as an account token: the server is the authority on what a token may do, and tokens minted before the prefixes existed carry neither.

func (*Config) RequireAuth 

func (c *Config) RequireAuth() error

RequireAuth returns an old-CLI-compatible error when no token is available.

func (*Config) RequireProject 

func (c *Config) RequireProject() error

RequireProject returns an old-CLI-compatible error when no project is selected.

func (*Config) Save 

func (c *Config) Save() error

Save writes the config to ~/.volcano/config.json with owner-only permissions.

func (*Config) SetFunctionAlias added in v0.0.4 

func (c *Config) SetFunctionAlias(scope, alias, functionID string)

SetFunctionAlias stores alias in the given scope.

func (*Config) Token 

func (c *Config) Token() string

Token returns the configured token, with VOLCANO_TOKEN taking precedence unless env overrides are disabled.

func (*Config) WebURL added in v0.0.4 

func (c *Config) WebURL() string

WebURL returns the Volcano web URL for c.APIURL(). See WebURLForAPIURL for callers that already resolved the API URL through another path (e.g. a runtime override that doesn't flow through c.APIURL()).

func (*Config) WebURLForAPIURL added in v0.2.1 

func (c *Config) WebURLForAPIURL(apiURL string) string

WebURLForAPIURL returns the Volcano web URL for a specific, already-resolved API URL: VOLCANO_WEB_URL takes precedence, then an explicitly compiled-in default (e.g. via `make local`'s DEFAULT_WEB_URL, which differs from the shipped defaultCompiledWebURL literal only when someone set it), then a URL derived from apiURL (see deriveWebURL), then the shipped compiled default. The explicit compiled default has to win over derivation: otherwise a loopback API URL baked in alongside a non-conventional compiled web URL (e.g. a frontend dev server not on port 3000) would have its own compiled default silently overridden by the :3000 convention.

func (*Config) WebURLOverride added in v0.0.4 

func (c *Config) WebURLOverride() (string, bool)

WebURLOverride returns an explicit VOLCANO_WEB_URL value when one is set, reporting false otherwise. Used only by Signup, to fail fast on a misconfigured override before allocating a device code (see WebURLForAPIURL for the derived-origin precedence Signup otherwise falls back to). LoginWithBrowser does not use this: its browser flow opens the backend's device-authorization verification URL directly and never routes through Volcano Web.

type DocsSourceConfig added in v0.1.0 

type DocsSourceConfig struct {
	Repo string `json:"repo,omitempty"`
	Ref  string `json:"ref,omitempty"`
	Path string `json:"path,omitempty"`
}

DocsSourceConfig persists a documentation source override. Empty fields fall back to the compiled defaults during resolution.

type ProjectConfig 

type ProjectConfig struct {
	ID   string `json:"id"`
	Name string `json:"name"`
}

ProjectConfig represents the currently selected Volcano project.
