The command/notebook configuration file may contain the following fields. All fields are optional unless otherwise specified.
description: A human-readable description of the command/notebook. This does not need to be unique. The default description consists of a timestamp and the entrypoint of the command.
environment: Specifies the environment of the container that is used to execute the command/notebook. Default values are in bold. Note that if
kerasshould be unspecified, and vice versa.
os: The operating system used for the environment. Required to be "ubuntu16.04".
cuda: The CUDA version (if any) used for the environment. Accepted values are 10.0, "9.0", and "none".
python: The Python version that is used for the environment. Required to be "3.6.9".
tensorflow: The TensorFlow version (if any) that is installed. Accepted values are "1.14.0", "1.13.1", "1.12.0", and "none".
pytorch: The PyTorch version (if any) that is installed. Accepted values are "1.2.0", 1.1.0, and "none".
keras: The Keras version (if any) that is installed. Accepted values are "2.2.4" and "none".
custom_image: Specifies a custom Docker base image to use when executing the command. The custom image must be available via
docker pullto every PEDL agent host in the cluster. If a
custom_imageis specified, it is up to the user to ensure the required dependencies are installed for the command to run.
runtime_packagesmay be used to execute install additional dependencies and Python packages before the PEDL command is executed. If
runtime_packagesare specified, it is assumed that
pipis installed in the custom Docker image. If supplying a custom base image, please consult the Custom Docker Images documentation for more information.
force_pull_image: Forcibly pull the image from the Docker registry and bypass the Docker cache. Defaults to
environment_variables: Specifies a list of environment variables for the command container. Each element of the list should be a string of the form
runtime_commands: Specifies a list of shell commands to execute before running the PEDL command/notebook.
runtime_packages: Specifies a list of Python packages to install before running the PEDL command/notebook.
registry_auth: Specifies the Docker registry credentials to use when pulling a custom base Docker image, if needed.
resources: The resources PEDL allows a command/notebook to use.
slots: Specifies the number of slots to use for the command/notebook. The default value is 1. The maximum value is the number of slots on the agent in the cluster with the most slots. For example, PEDL will be unable to schedule a command that requests 4 slots if the PEDL cluster is composed of agents with 2 slots each.
bind_mounts: Specifies a collection of directories that are bind-mounted into the Docker containers for execution. This can be used to allow commands to access additional data that is not contained in the command context. This field should consist of an array of entries. Note that users should ensure that the specified host paths are accessible on all agent hosts (e.g., by configuring a network file system appropriately). Defaults to an empty list.
host_path: (required) The file system path on each agent to use. Must be an absolute filepath.
container_path: (required) The file system path in the container to use. May be a relative filepath, in which case it will be mounted relative to the working directory inside the container. It is not allowed to mount directly into the working directory (
container_path == ".") to reduce the risk of cluttering the host filesystem.
read_only: Whether the bind-mount should be a read-only mount. Defaults to
propagation: (Advanced users only) Optional propagation behavior for replicas of the bind-mount. Defaults to
In addition to
pedl cmd run offers a
--config flag to directly set configuration options from the command line with
field can use the dot character (
.) to indicate nested fields (e.g.
value will be interpreted as a comma-separated list if it contains any commas. Options set by
--config take precedence over those set by
