3.1. Environment variables


You can set this environment variable in order to specify to which REANA cloud instance your client should connect and a valid token. For example:

$ export REANA_SERVER_URL=https://reana.cern.ch


You should specify valid access token for the REANA cloud instance you would like to use. For example:


The token should have been given to you by the REANA cluster administrators.


You can set this environment variable in order to specify a concrete workflow you would like to work on. (As an alternative to specifying --workflow option in commands.) For example:

$ export REANA_WORKON=myfirstanalysis

will work on the latest run of your “myfirstanalysis” workflow.

Note that you can also specify a concrete run number:

$ export REANA_WORKON=myfirstanalysis.3

which will permit to work on the third run of the “myfirstanalysis” workflow, for example to check out past input and output files.

You can list all your workflow runs and their statuses by doing:

$ reana-client workflows

and set REANA_WORKON to the one you would like to work on.

3.2. Usage

3.2.1. Overview

Please see the Getting Started section for a basic reana-client use case scenario.

3.2.2. Uploading analysis assets

Uploading files or directories to an analysis workspace is simple as:

$ reana-client upload file1 file2 directory1
File file1 was successfully uploaded.
File file2 was successfully uploaded.
File directory1/file3 was successfully uploaded.

Directory structures are maintained, i.e. directory1 exists in the workspace.

Note that symbolic links are resolved at the moment of upload so that a hard copy of the link target is uploaded to the cloud storage workspace. The link is not maintained throughout the workflow execution.

3.3. Examples

You can get inspiration on how to structure your REANA-compatible research data analysis from several reana-demo-... examples provided on GitHub.

3.4. Commands

The full list of reana-client commands with their documented options is available in the CLI API documentation.
