dtaas 0.1.0

DTaaS CLI

DTaaS Command Line Interface

This is a command line tool for the INTO-CPS-Association Digital Twins as a Service.

Prerequisite

Please visit and download the DTaaS Software.

The DTaaS service with base users and essential containers should be up and running before using the CLI.

Installation

Simply install using:

We recommend installing this in a virutal environment.

Steps to install:

• Change the working folder:

cd <DTaaS-directory>/cli

• We recommend installing this in a virtual environment. Create and activate a virtual environment.

• To install, simply:

pip install dtaas

Usage

Setup

The base DTaaS system should be up and running before adding/deleting users with the CLI.

Additionally, Setup the dtaas.toml file in the cli directory:

• Set common.server-dns to domain name of your server. If you want to bring up the server locally, please set this to "localhost".

• Set the path to the full system path of the DTaaS directory.

[common]
# absolute path to the DTaaS application directory
server-dns = "localhost"
path = "/home/Desktop/DTaaS"

Add users

To add new users using the CLI, fill in the users.add list in dtaas.toml with the Gitlab instance usernames of the users to be added

[users]
# matching user info must present in this config file
add = ["username1","username2", "username3"]

Then simply:

dtaas admin user add

Caveat

This brings up the containers, without the AuthMS authentication.

• Currently the email fields for each user in dtaas.toml are not in use, and are not necessary to fill in. These emails must be configured manually for each user in the docker/conf.local or docker/conf.server files and the traefik-forward-auth container must be restarted. This is done as follows:

• Go to the docker directory

cd <DTaaS>/docker

• Add two lines to the conf.local file

rule.onlyu4.action=allow
rule.onlyu4.rule=PathPrefix(`/user4`)

• Add three lines to the conf.server file

rule.onlyu3.action=auth
rule.onlyu3.rule=PathPrefix(`/user3`)
rule.onlyu3.whitelist = [e-mail]

Run the appropritate command for a server/local installation:

docker compose -f compose.server.yml --env-file .env up -d --force-recreate traefik-forward-auth

docker compose -f compose.local.yml --env-file .env up -d --force-recreate traefik-forward-auth

The new users are now added to the DTaaS instance, with authorization enabled.

Delete users

TO delete existing users, fill in the users.delete list in dtaas.toml_ with the Gitlab instance usernames of the users to be deleted.

Make sure you are in the cli directory.

Then simply:

dtaas admin user delete

Additional Points to Remember

• The user add CLI will add and start a container for a new user. It can also start a container for an existing user if that container was somehow stopped. It shows a Running status for existing user containers that are already up and running, it doesn't restart them.

• user add and user delete CLIs return an error if the add and delete lists in dtaas.toml are empty, respectively.
