& is a reverse application operator. This provides notational convenience. Its precedence is one higher than that of the forward application operator $, which allows & to be nested in $.

>>> 5 & (+1) & show
"6"

Unwrap a ResourceT transformer, and call all registered release actions.

Note that there is some reference counting involved due to resourceForkIO. If multiple threads are sharing the same collection of resources, only the last call to runResourceT will deallocate the resources.

NOTE Since version 1.2.0, this function will throw a ResourceCleanupException if any of the cleanup functions throw an exception.

Since: resourcet-0.3.0

Convenient alias for ResourceT IO.

Parameters for a running a Docker container.

Since: 0.1.0.0

Default ContainerRequest. Used as base for every Docker container.

Since: 0.1.0.0

Set the name of a Docker container. This is equivalent to invoking docker run with the --name parameter.

Since: 0.1.0.0

Set the name of a Docker container. This is equivalent to invoking docker run with the --name parameter.

Since: 0.4.0.0

Set the name randomly given of a Docker container. This is equivalent to omitting the --name parameter calling docker run.

Since: 0.4.0.0

Set the name randomly suffixed of a Docker container. This is equivalent to invoking docker run with the --name parameter.

Since: 0.4.0.0

The command to execute inside the Docker container. This is the equivalent of passing the command on the docker run invocation.

Since: 0.1.0.0

The volume mounts to link to Docker container. This is the equivalent of passing the command on the docker run -v invocation.

Wether to remove the container once exited. This is equivalent to passing --rm to docker run. (default is True).

Since: 0.1.0.0

Set the environment for the container. This is equivalent to passing --env key=value to docker run.

Since: 0.1.0.0

Set the network the container will connect to. This is equivalent to passing --network network_name to docker run.

Since: 0.4.0.0

Set the network the container will connect to. This is equivalent to passing --network network_name to docker run.

Since: 0.4.0.0

Since: 0.1.0.0

Forwards container logs to the given LogConsumer once ran.

Since: 0.4.0.0

Set exposed ports on the container. This is equivalent to setting --publish $PORT to docker run. Docker assigns a random port for the host port. You will have to use containerIp and containerPort to connect to the published port.

  container <- run $ containerRequest redis & setExpose [ 6379 ]
  let (redisHost, redisPort) = (containerIp container, containerPort container 6379)
  print (redisHost, redisPort)

Since: 0.1.0.0

Get an Image from a tag.

Since: 0.1.0.0

Build the image from a build path and an optional path to the Dockerfile (default is Dockerfile)

waitUntilTimeout n waitUntilReady waits n seconds for the container to be ready. If the container is not ready by then a TimeoutException will be thrown.

Since: 0.1.0.0

Since: 0.4.0.0

Waits until the port of a container is ready to accept connections. This combinator should always be used with waitUntilTimeout.

Since: 0.1.0.0

A low-level primitive that allows scanning the logs for specific log lines that indicate readiness of a container.

The Handles passed to the function argument represent stdout and stderr of the container.

Since: 0.1.0.0

Since: 0.1.0.0

Get the container's network alias. Takes the first alias found.

Since: 0.4.0.0

Since: 0.4.0.0

Looks up an exposed port on the host.

Since: 0.1.0.0

Returns the domain and port exposing the given container's port. Differs from containerPort in that containerAddress will return the container's domain and port if the program is running in the same network. Otherwise, containerAddress will use the exposed port on the Docker host.
