3. Configuration
nd uses a JSON formatted configuration file used for storing certain kinds of information, such as the authentication and authorization options. By default, this configuration file is unique by user. It is stored in its home directory.
For Linux and macOS, the default configuration file location is .config/.nd/config.json which is store in the $HOME. For Windows, the configuration file is stored in $AppData$.
You can display the configuration file location in using the command nd --help:
You can use the --config value where value is the path to a JSON formatted configuration file that nd uses for storing data. The ND_CONFIG environment variable can be used to set the value.
Store the configuration file in a 'central' directory to allow each user to get the same nd client configuration. For this, the --config-dir value is available.
Command
Command
Description
--config value
this option specifies the JSON filename where the configuration is stored
--config-dir value
this option specifies the directory where the JSON configuration is stored
SSL
nd client allows SSL configuration to communicate with the Data Mover service which listen in HTTPS. It is required to add the public certificate generated with the server.
The public certificate file has to be stored in this config-dir folder: .config/.nd/certs/CAs/.
The certificates on the server side have been generated following this command:
this refer to the node which hosts the following service DATA MANAGEMENT WEB SERVICES
--username
this is the username to grant authorization to the service
--password
this is the password associated to the username that will grant the access to the service
OpenID configuration
The nd client provides an OpenID authentication mechanism. In this case, nd Client has to be configured with the appropriated IDP to handle proper token management.
this refer to the node which hosts the following service DATA MANAGEMENT WEB SERVICES
--authorization-endpoint
this is the endpoint url to grant authorization to the service
--token-endpoint
this url is used to programmatically request tokens
--client-id
this refer to the client identifier which is provided by the OpenID provider
--persist-session
persist Device Authorization session on disk for 1 hour (default: true)
--persist-session-renew
if persist session is enabled, renew the token (default: false)
The standard behavior is to request a token, which is automatic if there is no token available. The token will be stored in a cache during 15 minutes. The --persist-session-renew option can be defined to true to force a request token process any time the user has to interface with the nd client.
The token renewal is automatic based on the renewal token.
Alias & default flags
Description
Alias & default flags allow structuration of different group of settings. Different alias can be defined in the configuration file.
Definition of alias & default flags
Alias and flags are declared in the configuration file ~/.config/.nd/config.json". Default flags are defined for each available parameter command. Flags can be overwritted in the nd command.
Example in config file:
{// ...// default: name of alias used by default"default": { // ..."default_flags": {// this is the name of the command, example: nd copy"copy": {// this is the flag, example: nd copy --md project_domain_name=MYPROJECTDOMAIN --md user_domain_name=MYUSERDOMAIN"md": ["project_domain_name=MYPROJECTDOMAIN","user_domain_name=MYUSERDOMAIN"] } } },// myorganisation: name of another alias"myorganisation": { // ... }}
Alias usage
The nd command allows the usage of alias, example : nd --alias myorganisation copy
4. Data Mover Service Status
Command
Command
Description
nd admin status
retrieve the status and the health of each services part of the cluster
nd admin logs
retrieve all Logs and return their contents
Data Management Monitoring Services
nd admin status command requests the Data Management Monitoring service to retrieve the status and health of each services part of the cluster. This command returns list of services. The following information are displayed:
add callback. Format is type:./path/to/file (accepts multiple inputs)
--defer
when requesting the run of the task, will defer it for later with an unique ID (default: false)
--no-run
just create the task, don't run it (default: false)
--progress
when running the task, display live progress (default: true)
--recursive
copy directories recursively (default: false)
--ignore-hidden
ignore hidden files and folders, starting with (default: false)
--overwrite
overwrite existing entries (default: false)
--priority value
task priority [0..9] (default: 0)
--working-dir value
set working directory
Working Directory Explanation
The definition of a working directory allows to define where the files will be stored at the destination. Different options are available, they are described in the following definition.
The objective of defer task is to create the task and already initiate the authentication process but defers its execution. Unique IDs will be returned.
This command list all tasks created by the user in the data mover service.
The columns describe:

Description
TASK ID
ID of the task
TASK NAME
