## Quickstart
**Dependencies**
- [Go >= 1.21](https://go.dev/)
- `GNU Make`
```shell
# Start server and a local agent
make watch
# In an other terminal
# Create an admin token
make .emissary-admin-token
# Create a new tenant
make .emissary-tenant
# Create a new writer token for this tenant
make .emissary-token
# Claim the agent for your newly created tenant
make claim-agent
# Query your agents
./bin/server client agent query
# Load sample specs for your agent
make load-sample-specs
## Optional: reset your workspace

# Authentification et autorisation
## Authentification
Emissary utilise des [**JSON Web Token**](https://fr.wikipedia.org/wiki/JSON_Web_Token) (JWT) afin d'authentifier les appels à son API REST.
L'implémentation est compatible avec tout serveur d'authentification exposant une URL proposant un [**JSON Web Key Set**](https://www.ory.sh/docs/hydra/jwks#the-role-of-well-knownjwksjson).
La plupart des serveurs OpenID Connect exposent un point d'entrée du type [`/.well-known/jwks.json`](https://www.ory.sh/docs/hydra/jwks#the-role-of-well-knownjwksjson) remplissant ce rôle.
Emissary est également en capacité à fonctionner en mode autonome en générant des JWTs signés par une clé privée locale.
## Ségrégation des ressources
Emissary suit une stratégie ["multitenant"](https://fr.wikipedia.org/wiki/Multitenant) de séparer les ressources par organisation.
Un utilisateur est obligatoirement associé à un `tenant`` et ne peut opérer que sur les ressources associées à celui ci.
## Autorisation
Au sein d'un `tenant`, un utilisateur peut avoir un des rôles suivants:
- `writer` - Autorisé à visualiser et modifier les ressources;
- `reader` - Autorisé à visualiser les ressources.
Un rôle spécial `admin` permet la création et la suppression de `tenants`.
