Public Member Functions
	FileSink (const std::string &containerId, std::shared_ptr< rt_dobby_schema > &containerConfig)
	A logging sink that sends the contents of the container stdout/err to a given file. The file can have a size limit set.
void	DumpLog (const int bufferFd) override
	Reads all the available data from the provided fd and writes it to the output file. Does not attempt to seek the file descriptor back to the start.
void	process (const std::shared_ptr< AICommon::IPollLoop > &pollLoop, epoll_event event) override
	Called by the pollLoop when an event occurs on the container ptty.

Private Member Functions
int	openFile (const std::string &pathName)
	Opens the log file at a given path. Will create a new file when called, and subsequent writes will append to the file.

Constructor & Destructor Documentation

FileSink()

FileSink::FileSink	(	const std::string &	containerId,
		std::shared_ptr< rt_dobby_schema > &	containerConfig
	)

A logging sink that sends the contents of the container stdout/err to a given file. The file can have a size limit set.

Will create the requested file providing the directory exists. Creates a new file each time this class is instantiated

Member Function Documentation

DumpLog()

void FileSink::DumpLog ( const int  bufferFd )

overridevirtual

Reads all the available data from the provided fd and writes it to the output file. Does not attempt to seek the file descriptor back to the start.

If file limit is hit, will send data to /dev/null

Parameters

[in]

bufferFd

The fd to read from

Implements ILoggingSink.

openFile()

int FileSink::openFile ( const std::string &  pathName )

private

Opens the log file at a given path. Will create a new file when called, and subsequent writes will append to the file.

Parameters

[in]

pathName

Where to create the file

Returns

Opened file descriptor

process()

void FileSink::process ( const std::shared_ptr< AICommon::IPollLoop > &  pollLoop, epoll_event  event  )

overridevirtual

Called by the pollLoop when an event occurs on the container ptty.

Reads the contents of the ptty and logs to a file

Implements AICommon::IPollSource.
