Documentation

data DockerException Source #

Failing to interact with Docker results in this exception being thrown.

Since: 0.1.0.0

Constructors

DockerException
Fields exitCode :: ExitCode Exit code of the underlying Docker process. args :: [Text] Arguments that were passed to Docker. stderr :: Text Docker's STDERR output.
InspectUnknownContainerId
Fields id :: ContainerId Id of the `Container` that we tried to lookup the port mapping.
InspectOutputInvalidJSON
Fields id :: ContainerId Id of the `Container` that we tried to lookup the port mapping.
InspectOutputMissingNetwork
Fields id :: ContainerId Id of the `Container` that we tried to lookup the port mapping.
InspectOutputUnexpected
Fields id :: ContainerId Id of the `Container` that we tried to lookup the port mapping.
UnknownPortMapping
Fields id :: ContainerId Id of the `Container` that we tried to lookup the port mapping. port :: Text Textual representation of port mapping we were trying to look up.

Running docker

docker :: MonadIO m => Tracer -> [Text] -> m String Source #

Internal function that runs Docker. Takes care of throwing an exception in case of failure.

Since: 0.1.0.0

dockerWithStdin :: MonadIO m => Tracer -> [Text] -> Text -> m String Source #

Internal function that runs Docker. Takes care of throwing an exception in case of failure.

Since: 0.1.0.0

Following logs

data Pipe Source #

A data type indicating which pipe to scan for a specific log line.

Since: 0.1.0.0

Constructors

Stdout	Refer to logs on STDOUT.

type LogConsumer = Pipe -> ByteString -> IO () Source #

An abstraction for forwarding logs.

Since: 0.5.0.0

consoleLogConsumer :: LogConsumer Source #

A simple LogConsumer that writes log lines to stdout and stderr respectively.

Since: 0.5.0.0

dockerFollowLogs :: MonadResource m => Tracer -> ContainerId -> LogConsumer -> m () Source #

Forwards container logs to a LogConsumer. This is equivalent of calling docker logs containerId --follow
