Permission management
In this section you will learn how to deal with the permission management system in vantage6.
🧻 Rules and Roles
Each user can have multiple roles and rules assigned to him. Roles consist of a set of rules. The final permissions the user has are a union of all the rules assigned to him either by direct assignment or through a role.
As an organization is it possible to define your own set of rules within your rule space. This means that you can not assign any rule that you do not own. This approach allows you to implement your own roles and distribution of permissions within your organization.
📦 Predefined Roles
There are a few pre-defined roles.
role
description
superuser
super user with all permissions, can be assigned only by a superuser itself.
node
role that all nodes have
containers
role that all containers have
???
🐕🦺 How to assign 'em
The server administrator can assign rules and roles through the iPython shell. Other users can use API to assign roles/rules that they own to other users.
First we need to initialize the client:
from vantage6.client import Client
# setting the verbose option to True gives you a lot more
# information
client = Client("https://harukas.vantage6.ai", 443, "", verbose=True)
# Welcome to

client.setup_encryption(None)
# Display all available rules, but only display the description and id
# the save some space
client.rule.list(fields=('id', 'description'))
# [{'id': 1, 'description': 'view any node'}, {'id': 2, 'description':
# 'view your own node info'}, {'id': 3, 'description': 'edit any node'},
# {'id': 4, 'description': 'edit node that is part of your organization'},
# {'id': 5, 'description': 'create node for any organization'}, ... ]
# Display all roles. Roles consist of a set of rules. We only show the id
# name and assigned users
client.role.list(fields=('id', 'name', 'users'))
# [{'id': 1, 'name': 'container', 'users': None}, {'id': 2, 'name': 'node',
# 'users': None}, {'id': 3, 'name': 'Root', 'users': [{'id': 1, 'link':
# '/user/1', 'methods': ['GET', 'DELETE', 'PATCH']}]}, {'id': 4, 'name':
# 'iknl-admin', 'users': [{'id': 4, 'link': '/user/4', 'methods': ['GET',
# 'DELETE', 'PATCH']}]}, {'id': 5, 'name': 'jrc-admin', 'users': [{'id': 5,
# 'link': '/user/5', 'methods': ['GET', 'DELETE', 'PATCH']}]}]To display rules and roles you can use the rule and role part of the client. Note that you can limit the keys of the output by specifying the fields argument.
# Display all available rules, but only display the description and id
# the save some space
client.rule.list(fields=('id', 'description'))
# [{'id': 1, 'description': 'view any node'}, {'id': 2, 'description':

# 'DELETE', 'PATCH']}]}, {'id': 5, 'name': 'jrc-admin', 'users': [{'id': 5,
# 'link': '/user/5', 'methods': ['GET', 'DELETE', 'PATCH']}]}]To assign a role or rule to a user you need to update the user:
frank = client.user.get(1)
print(frank)
# {'email': '[email protected]', 'last_seen': '2021-03-23T10:12:14.463590+00:00',
# 'organization': {'id': 1, 'link': '/organization/1', 'methods': ['PATCH',
# 'GET']}, 'username': 'root', 'lastname': 'Martin', 'id': 1, 'type': 'user',
# 'ip': '172.17.21.1', 'roles': [{'id': 3, 'link': '/role/3', 'methods': ['GET',
# 'DELETE', 'PATCH']}], 'firstname': 'frank', 'status': None, 'rules': None}
# It is always a good idea to check the documentation of the update function
# first
help(client.user.update)
