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:

$ nd --help 
NAME:
   nd - Nodeum CLI
....
   --config value                  path to configuration file (default: <config-dir>/
                                   config.json) [$ND_CONFIG]
   --config-dir value, -C value    path to configuration folder (default: "/home/
                                   nodeum01/.config/.nd") [$ND_CONFIG_DIR]

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

CommandDescription

--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:

$ openssl11 req -x509 -newkey rsa:4096 -sha256 -days 3650 -nodes \
\-keyout ./nodeum_certs/private.key \
\-out ./nodeum_certs/public.crt \
\-subj "/CN=nodeum-qualif.mt-c.local" \
\-addext "subjectAltName=DNS:nodeum.domain.local,DNS:localhost,IP:127.0.0.1,
IP:1.1.1.1"

Where 1.1.1.1 is the ip of the nginx interface and nodeum.domain.local is its hostname including domain name.

Authentication and Authorization

Description

Two authentifcation options are available:

  • Username / Password

  • IDP with OpenID

Command

CommandDescription

nd config save

this command save the nd configuration for authentication

nd config review

this command display the information related to the credentials

nd config clear-session

clear persisted session

Username / Password configuration

The nd client provides a basic method of authentication in using Username / Password credentials.

$ nd config save \
\--url=http:// \
\--username= \
\--password=
OptionDescription

--url

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.

The basic configuration is the following one:

$ nd config save \
\--url=http:// \
\--authorization-endpoint= \
\--token-endpoint= \
\--client-id= \
\--scopes="openid,profile,offline_access,email"
OptionDescription

--url

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

CommandDescription

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:

  • Service Status

  • Service version

  • Host where the service is deployed

  • Its uptime

nod-cloud://cloud_storage/container

Available Parameters

OptionDescription

--callback type:./path/to/file

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.
