type LocalFS

LocalFS is a plugins.FS that allows accessing files on the local file system.

func NewLocalFS 

func NewLocalFS(basePath string) LocalFS

NewLocalFS returns a new LocalFS that can access any file in the specified base path on the filesystem. basePath must use os-specific path separator for Open() to work properly.

func (LocalFS) Base 

func (f LocalFS) Base() string

Base returns the base path for the LocalFS. The returned string uses os-specific path separator.

func (LocalFS) Files 

func (f LocalFS) Files() ([]string, error)

Files returns a slice of all the relative file paths on the LocalFS. The returned strings can be passed to Open() to open those files. The returned strings use os-specific path separator.

func (LocalFS) Open 

func (f LocalFS) Open(name string) (fs.File, error)

Open opens the specified file on the local filesystem. The provided name must be a relative file name that uses os-specific path separators. The function returns the corresponding fs.File for accessing the file on the local filesystem. If a nil error is returned, the caller should take care of calling Close() the returned fs.File. If the file does not exist, ErrFileNotExist is returned.

func (LocalFS) Remove 

func (f LocalFS) Remove() error

Remove removes a plugin from the local filesystem by deleting all files in the folder. It returns ErrUninstallInvalidPluginDir is the plugin does not contain plugin.json nor dist/plugin.json.

type LocalFile 

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

LocalFile implements a fs.File for accessing the local filesystem.

func (*LocalFile) Close 

func (p *LocalFile) Close() error

Close closes the file. If the file was never open, nil is returned. If the file is already closed, an error is returned.

func (*LocalFile) Read 

func (p *LocalFile) Read(b []byte) (int, error)

Read reads up to len(b) bytes from the File and stores them in b. It returns the number of bytes read and any error encountered. At end of file, Read returns 0, io.EOF. If the file is already open, it is opened again, without closing it first. The file is not closed at the end of the read operation. If a non-nil error is returned, it must be manually closed by the caller by calling Close().

func (*LocalFile) Stat 

func (p *LocalFile) Stat() (fs.FileInfo, error)

Stat returns a FileInfo describing the named file. It returns ErrFileNotExist if the file does not exist, or ErrPluginFileRead if another error occurs.

type StaticFS struct {
	FS
	// contains filtered or unexported fields
}

StaticFS wraps an FS and allows accessing only the files in the allowList. This is a more secure implementation of a FS suitable for production environments. The keys of the allow list must be in the same format used by the underlying FS' Open() method.

func NewStaticFS 

func NewStaticFS(fs FS) (StaticFS, error)

NewStaticFS returns a new StaticFS that can access the files on an underlying FS, but only if they are also specified in a static list, which is constructed when creating the object by calling Files() on the underlying FS.

func (StaticFS) Files 

func (f StaticFS) Files() ([]string, error)

Files returns a slice of all static file paths relative to the base path.

func (StaticFS) Open 

func (f StaticFS) Open(name string) (fs.File, error)

Open checks that name is an allowed file and, if so, it returns a fs.File to access it, by calling the underlying FS' Open() method. If access is denied, the function returns ErrFileNotExist.

type StaticRoute 

type StaticRoute struct {
	PluginID  string
	Directory string
}

type StaticRouteResolver 

type StaticRouteResolver interface {
	Routes(ctx context.Context) []*StaticRoute
}

type Store 

type Store interface {
	// Plugin finds a plugin by its ID.
	Plugin(ctx context.Context, pluginID string) (PluginDTO, bool)
	// Plugins returns plugins by their requested type.
	Plugins(ctx context.Context, pluginTypes ...Type) []PluginDTO
}

Store is the publicly accessible storage for plugins.

type Type 

type Type string
const (
	TypeDataSource     Type = "datasource"
	TypePanel          Type = "panel"
	TypeApp            Type = "app"
	TypeRenderer       Type = "renderer"
	TypeSecretsManager Type = "secretsmanager"
)

func (Type) IsValid 

func (pt Type) IsValid() bool

type URLParam 

type URLParam struct {
	Name    string `json:"name"`
	Content string `json:"content"`
}

URLParam describes query string parameters for a url in a plugin route

type UpdateInfo 

type UpdateInfo struct {
	PluginZipURL string
}
