# Devicehub
|
||
|
||
Devicehub is a distributed IT Asset Management System focused in reusing devices, created under the project [eReuse.org](https://www.ereuse.org)
|
||
|
||
This README explains how to install and use Devicehub. [The documentation](http://devicehub.ereuse.org) explains the concepts and the API.
|
||
|
||
Devicehub is built with [Teal](https://github.com/ereuse/teal) and [Flask](http://flask.pocoo.org).
|
||
|
||
# Installing
|
||
The requirements are:
|
||
|
||
0. Required
|
||
- python3.9
|
||
- [PostgreSQL 11 or higher](https://www.postgresql.org/download/).
|
||
- Weasyprint [dependencie](http://weasyprint.readthedocs.io/en/stable/install.html)
|
||
|
||
1. Generate a clone of the repository.
|
||
```
|
||
git clone git@github.com:eReuse/devicehub-teal.git
|
||
cd devicehub-teal
|
||
```
|
||
|
||
2. Create a virtual environment and install Devicehub with *pip*.
|
||
```
|
||
python3.9 -m venv env
|
||
source env/bin/activate
|
||
pip3 install -U -r requirements.txt -e .
|
||
pip3 install Authlib==1.2.1
|
||
```
|
||
|
||
3. Create a PostgreSQL database called *devicehub* by running [create-db](examples/create-db.sh):
|
||
|
||
- In Linux, execute the following two commands (adapt them to your distro):
|
||
|
||
1. `sudo su - postgres`.
|
||
2. `bash examples/create-db.sh devicehub dhub`, and password `ereuse`.
|
||
|
||
- In MacOS: `bash examples/create-db.sh devicehub dhub`, and password `ereuse`.
|
||
|
||
Configure project using environment file (you can use provided example as quickstart):
|
||
```bash
|
||
$ cp examples/env.example .env
|
||
```
|
||
|
||
4. Running alembic from oidc module.y
|
||
```
|
||
alembic -x inventory=dbtest upgrade head
|
||
```
|
||
|
||
5. Running alembic from oidc module.y
|
||
```
|
||
cd ereuse_devicehub/modules/oidc
|
||
alembic -x inventory=dbtest upgrade head
|
||
```
|
||
|
||
6. Running alembic from dpp module.
|
||
```
|
||
cd ereuse_devicehub/modules/dpp/
|
||
alembic -x inventory=dbtest upgrade head
|
||
```
|
||
|
||
7. Add a suitable app.py file.
|
||
```
|
||
cp examples/app.py .
|
||
```
|
||
|
||
8. Generate a minimal data structure.
|
||
```
|
||
flask initdata
|
||
```
|
||
|
||
9. Add a new server to the 'api resolver' to be able to integrate it into the federation.
|
||
The domain name for this new server has to be unique. When installing two instances their domain name must differ: e.g. dpp.mydomain1.cxm, dpp.mydomain2.cxm.
|
||
If your domain is dpp.mydomain.cxm:
|
||
```
|
||
flask dlt_insert_members http://dpp.mydomain.cxm
|
||
```
|
||
|
||
modify the .env file as indicated in point 3.
|
||
Add the corresponding 'DH' in ID_FEDERATED.
|
||
example: ID_FEDERATED='DH10'
|
||
|
||
10. Do a rsync api resolve.
|
||
```
|
||
flask dlt_rsync_members
|
||
```
|
||
|
||
11. Register a new user in devicehub.
|
||
```
|
||
flask adduser email@cxm.cxm password
|
||
```
|
||
|
||
12. Register a new user to the DLT.
|
||
```
|
||
flask dlt_register_user email@cxm.cxm password Operator
|
||
```
|
||
|
||
13. Finally, run the app:
|
||
|
||
```bash
|
||
$ flask run --debugger
|
||
```
|
||
|
||
The error ‘bdist_wheel’ can happen when you work with a *virtual environment*.
|
||
To fix it, install in the *virtual environment* wheel
|
||
package. `pip3 install wheel`
|
||
|
||
# Testing
|
||
|
||
1. `git clone` this project.
|
||
2. Create a database for testing executing `create-db.sh` like the normal installation but changing the first parameter from `devicehub` to `dh_test`: `create-db.sh dh_test dhub` and password `ereuse`.
|
||
3. Execute at the root folder of the project `python3 setup.py test`.
|
||
|
||
# Upgrade a deployment
|
||
|
||
For upgrade an instance of devicehub you need to do:
|
||
|
||
```bash
|
||
$ cd $PATH_TO_DEVIHUBTEAL
|
||
$ source venv/bin/activate
|
||
$ git pull
|
||
$ alembic -x inventory=dbtest upgrade head
|
||
```
|
||
|
||
If all migrations pass successfully, then it is necessary restart the devicehub.
|
||
Normaly you can use a little script for restart or run.
|
||
```
|
||
# systemctl stop gunicorn_devicehub.socket
|
||
# systemctl stop gunicorn_devicehub.service
|
||
# systemctl start gunicorn_devicehub.service
|
||
```
|
||
|
||
# OpenId Connect:
|
||
We want to interconnect two devicehub instances already installed. One has a set of devices (OIDC client), the other has a set of users (OIDC identity server). Let's assume their domains are: dpp.mydomain1.cxm, dpp.mydomain2.cxm
|
||
20. In order to connect the two devicehub instances, it is necessary:
|
||
* 20.1. Register a user in the devicehub instance acting as OIDC identity server.
|
||
* 20.2. Fill in the openid connect form.
|
||
* 20.3. Add in the OIDC client inventory the data of client_id, client_secret.
|
||
|
||
For 20.1. This can be achieved on the terminal on the devicehub instance acting as OIDC identity server.
|
||
```
|
||
flask adduser email@cxm.cxm password
|
||
```
|
||
|
||
* 20.2. This is an example of how to fill in the form.
|
||
|
||
In the web interface of the OIDC identity service, click on the profile of the just added user, select "My Profile" and click on "OpenID Connect":
|
||
Then we can go to the "OpenID Connect" panel and fill out the form:
|
||
|
||
The important thing about this form is:
|
||
* "Client URL" The URL of the OIDC Client instance, as registered in point 12. dpp.mydomain1.cxm in our example.
|
||
* "Allowed Scope" has to have these three words:
|
||
```
|
||
openid profile rols
|
||
```
|
||
* "Redirect URIs" it has to be the URL that was put in "Client URL" plus "/allow_code"
|
||
* "Allowed Grant Types" has to be "authorization_code"
|
||
* "Allowed Response Types" has to be "code"
|
||
* "Token Endpoint Auth Method" has to be "Client Secret Basic"
|
||
|
||
After clicking on "Submit" the "OpenID Connect" tab of the user profile should now include details for "client_id" and "client_secret".
|
||
|
||
* 20.3. In the OIDC client inventory run: (in our example: url_domain is dpp.mydomain2.cxm, client_id and client_secret as resulting from the previous step)
|
||
```
|
||
flask add_client_oidc url_domain client_id client_secret
|
||
```
|
||
After this step, both servers must be connected. Opening one DPP page on dpp.mydomain1.cxm (OIDC Client) the user can choose to authenticate using dpp.mydomain2.cxm (OIDC Server).

## Generating the docs
|
||
|
||
|
||
1. `git clone` this project.
|
||
2. Install plantuml. In Debian 9 is `# apt install plantuml`.
|
||
3. Execute `pip3 install -e .[docs]` in the project root folder.
|
||
4. Go to `<project root folder>/docs` and execute `make html`. Repeat this step to generate new docs.
|
||
|
||
To auto-generate the docs do `pip3 install -e .[docs-auto]`, then execute, in the root folder of the project `sphinx-autobuild docs docs/_build/html`.
