REANA-Client docs¶

REANA-Client is a component of the REANA reusable and reproducible research data analysis platform. It provides a command-line tool that allows researchers to submit, run, and manage their computational workflows.

seed workspace with input code and data
run computational workflows on remote compute clouds
list submitted workflows and enquire about their statuses
download results of finished workflows

Installation¶

$ # create new virtual environment
$ virtualenv ~/.virtualenvs/reana
$ source ~/.virtualenvs/reana/bin/activate
$ # install reana-client
$ pip install reana-client

Usage¶

The detailed information on how to install and use REANA can be found in docs.reana.io.

Bundling additional workflow source files¶

The create and validate commands upload a scoped specification bundle for server-side workflow loading. Declare every imported source explicitly under workflow.files or workflow.directories so it is available to the loader.

For example, given this Snakemake project:

analysis/
├── reana.yaml
├── Snakefile
└── rules/
    └── common.smk

where Snakefile contains include: "rules/common.smk", declare the included source in reana.yaml:

version: 0.9.0
workflow:
  type: snakemake
  file: Snakefile
  directories:
    - rules

Paths are relative to the directory containing the selected specification. Absolute paths, paths that escape through .., and symbolic links are rejected. Use workflow.files only for workflow definitions and configuration needed while loading the workflow; input datasets belong under inputs.files or inputs.directories.

Validation snapshots accept at most 1,000 files, 2,000 directories, 100 MiB of file content, and 64 relative path components. Symbolic links are not followed.

reana-client validate --environments performs offline image-reference checks and reports effective runtime identities. Add --pull to verify availability and inspect those images with your local container runtime and registry credentials; the REANA server does not contact image registries.

restart¶

Restart previously run workflow.

The restart command allows to restart a previous workflow on the same workspace.

Note that workflow restarting can be used in a combination with operational options FROM and TARGET. You can also pass a modified workflow specification with -f or --file flag.

The -f/--file flag replaces only the specification (input parameters, operational options, and workflow type/definition metadata). The workflow source files (Snakefiles, CWL files, rules, …) are reused from the existing workspace: a restart does not re-upload them. If the replacement specification references new or changed workflow source, upload those files to the workspace first; otherwise validation fails naming the missing file.

You can furthermore use modified input prameters using -p or --parameters flag and by setting additional operational options using -o or --options. The input parameters and operational options can be repetitive.

reana_client.api.client.add_secrets(secrets, overwrite, access_token)[source]¶

Add new secrets.

Parameters:

secrets –
dictionary containing all the secrets to be sent. The dictionary has the secret names for keys and for each key there is a dictionary with two fields:
- value: a base64 encoded file or literal string
- type: "file" or "env"
overwrite – whether secrets should be overwritten when they already exist.
access_token – access token of the current user.

Returns:

reana_client.api.client.close_interactive_session(workflow, access_token)[source]¶

Close an interactive workflow session.

Parameters:

Returns:

the relative path to the interactive session.

reana_client.api.client.create_workflow_from_bundle(reana_file, name, access_token)[source]¶

Create a workflow by uploading the raw specification bundle.

The server loads and validates the specification authoritatively (in a sandbox for Snakemake/CWL/Yadage), so the client does not run the workflow engines locally.

Parameters:

reana_file – path to the local reana.yaml specification file.
name – name of the workflow.
access_token – access token of the current user.

Returns:

server response dict with workflow_id, workflow_name and (optionally) validation_warnings.

reana_client.api.client.create_workflow_from_bundle_dir(bundle_dir, name, access_token)[source]¶

Create a workflow from declarations in bundle_dir/reana.yaml.

Used when the caller has assembled a local source directory (e.g. the reana-cwl-runner entrypoint). Only files explicitly selected by the specification’s validation-scope declarations are uploaded.

Parameters:

bundle_dir – directory containing the canonical specification and its declared workflow-definition files.
name – name of the workflow.
access_token – access token of the current user.

Returns:

server response dict.

reana_client.api.client.create_workflow_from_json(name, access_token, workflow_json=None, workflow_file=None, parameters=None, workflow_engine='yadage', outputs=None, workspace_path=None)[source]¶

Create a workflow from an inline JSON specification (deprecated).

Deprecated since version Write: a raw reana.yaml and call create_workflow_from_bundle() instead. The server now loads and validates the specification authoritatively, so a client-serialized specification is no longer accepted.

Only the documented inline serial use case is translated: it is the one shape the server-side loader can reconstruct, because a serial workflow is the only engine whose loader accepts an inline workflow.specification with no workflow.file. Every other historical call shape referenced local loader dependencies that a single dictionary does not identify, so those fail with migration guidance rather than silently submitting a specification the server cannot re-derive.

Parameters:

name – name or UUID of the workflow to be created.
access_token – access token of the current user.
workflow_json – workflow specification in JSON format.
workflow_file – workflow specification file path. No longer translatable; kept so historical calls fail with guidance.
parameters – workflow input parameters dictionary.
workflow_engine – one of the workflow engines. Only serial is translatable.
outputs – dictionary with expected workflow outputs.
workspace_path – accepted for call compatibility; unused.

Returns:

server response dict with workflow_id and workflow_name.

Raises:

ValueError – for call shapes that cannot be translated safely.

Example:

create_workflow_from_json(
    workflow_json=workflow_json,
    name='workflow_name.1',
    access_token='access_token',
    parameters={'files': ['file.txt'],
        'parameters': {'key': 'value'}},
    workflow_engine='serial')
