Ray Jobs CLI API Reference

This section contains commands for Ray Job Submission.

ray job submit

Submits a job to be run on the cluster.

By default (if –no-wait is not set), streams logs to stdout until the job finishes. If the job succeeded, exits with 0. If it failed, exits with 1.

Example:

ray job submit -- python my_script.py --arg=val

ray job submit [OPTIONS] ENTRYPOINT...

Options

--address <address>

Address of the Ray cluster to connect to. Can also be specified using the RAY_ADDRESS environment variable.

--job-id <job_id>

DEPRECATED: Use --submission-id instead.

--submission-id <submission_id>

Submission ID to specify for the job. If not provided, one will be generated.

--runtime-env <runtime_env>

Path to a local YAML file containing a runtime_env definition.

--runtime-env-json <runtime_env_json>

JSON-serialized runtime_env dictionary.

--working-dir <working_dir>

Directory containing files that your job will run in. Can be a local directory or a remote URI to a .zip file (S3, GS, HTTP). If specified, this overrides the option in --runtime-env.

--metadata-json <metadata_json>

JSON-serialized dictionary of metadata to attach to the job.

--entrypoint-num-cpus <entrypoint_num_cpus>

the quantity of CPU cores to reserve for the entrypoint command, separately from any tasks or actors that are launched by it

--entrypoint-num-gpus <entrypoint_num_gpus>

the quantity of GPUs to reserve for the entrypoint command, separately from any tasks or actors that are launched by it

--entrypoint-memory <entrypoint_memory>

the amount of memory to reserve for the entrypoint command, separately from any tasks or actors that are launched by it

--entrypoint-resources <entrypoint_resources>

a JSON-serialized dictionary mapping resource name to resource quantity describing resources to reserve for the entrypoint command, separately from any tasks or actors that are launched by it

--no-wait

If set, will not stream logs and wait for the job to exit.

--verify <verify>

Boolean indication to verify the server’s TLS certificate or a path to a file or directory of trusted certificates.

Default:

True

--headers <headers>

Used to pass headers through http/s to the Ray Cluster.please follow JSON formatting formatting {“key”: “value”}

--log-style <log_style>

If ‘pretty’, outputs with formatting and color. If ‘record’, outputs record-style without formatting. ‘auto’ defaults to ‘pretty’, and disables pretty logging if stdin is not a TTY.

Options:

auto | record | pretty

--log-color <log_color>

Use color logging. Auto enables color logging if stdout is a TTY.

Options:

auto | false | true

-v, --verbose

Arguments

ENTRYPOINT

Required argument(s)

Warning

When using the CLI, do not wrap the entrypoint command in quotes. For example, use ray job submit --working-dir="." -- python script.py instead of ray job submit --working-dir="." -- "python script.py". Otherwise you may encounter the error /bin/sh: 1: python script.py: not found.

Warning

You must provide the entrypoint command, python script.py, last (after the --), and any other arguments to ray job submit (e.g., --working-dir=".") must be provided before the two hyphens (--). For example, use ray job submit --working-dir="." -- python script.py instead of ray job submit -- python script.py --working-dir=".". This syntax supports the use of -- to separate arguments to ray job submit from arguments to the entrypoint command.
