Features Example The Graph of Relations API Check Example Write Custom Tuple Example Delete Tuple Example Client SDKs Community [?] Let's get connected: License README.md Permify - Open Source Authorization Service Permify Go Version Permify Go Report Card Permify Licence Permify Discord Channel Permify Docker Image Version Permify - Open source authorization as a service Permify is an open-source authorization service that you can run with docker and works on a Rest API. We publish & subscribe to your Postgres DB (listen DB). And based on a YAML schema file; we convert, coordinate and sync your authorization data as relation tuples into your DB (write db) you point at. And you can check authorization with single request based on those tuples. Data model is inspired by Google Zanzibar White Paper . Getting Started Permify consists of 3 main parts; data sync, authorization model, and enforcement checks. Move & Sync Data You can convert, coordinate & sync authorization data based on a YAML config file and schema in which you define your authorization relations. * ListenDB: Where your application data is stored. * WriteDB: Where your want to store relation tuples, audits , and decision logs. Permify creates a function in your Listen DB that has a trigger based on your config file. Any time you create, update, or delete data; we sync this data as relation tuples into writeDB. example config file app: name: 'permify' version: '0.0.1' http: port: '3476' logger: log_level: 'debug' rollbar_env: 'permify' database: listen: connection: postgres pool_max: 2 url: 'postgres://user:password@host:5432/database_name' write: connection: postgres pool_max: 2 url: 'postgres://user:password@host:5432/database_name' Modeling Authorization Logic You can create access decisions are based on the relationships a subject has with Permify Schema. For instance, only allowing Repository owners to push updates. entity user {} `table:users|identifier:id` entity organization { relation admin @user `rel:custom` relation member @user `rel:many-to-many|table:org_members|cols:org_id,user_id` action create_repository = admin or member action delete = admin } `table:organizations|identifier:id` entity repository { relation owner @user `rel:belongs-to|cols:owner_id` relation org @organization `rel:belongs-to|cols:organization_id` action push = owner action read = (owner or org.member) and org.admin action delete = org.admin or owner } `table:repositories|identifier:id` Entities Entities represent your main tables. The table name and the entity name here must be the same. For example, name of the user entity in our example represents user table in your database. Entity has 2 different parts. These are; * relations * actions Relations Relations represent relationships between entities. For example, each repository is related with an organization While the belongs_to is kept within the entity itself, the has one is kept in the table where it is related. And the many-to-many relation is kept in the pivot tables. Therefore, we need to specify the relationship types in the schema. * name: define the realtion * table (optional): the name of the pivot table. (Only for many-to-many relationships.) * rel: type of relationship (many-to-many, belongs-to or custom) * entity: the entity it's related with (e.g. user, organization, repo...) * cols: the columns you have created in your database. entity repository { relation owner @user `rel:belongs-to|cols:owner_id` relation org @organization `rel:belongs-to|cols:organization_id` } - Each repository belongs to an organization. which is defined as organization_id column in the repository table. Actions Actions describe what relations, or relation's relation can do. For example, only the repository owner can push to repository. action push = owner another example, organization admin (user with admin role) and action read = (owner or org.member) and org.admin - "User with a admin role and either owner of the repository, or member of the organization which repository belongs to" can read. Installation Container (Docker) With terminal 1. Open your terminal. 2. Run following line. docker run -d -p 3476:3476 --name permify-container -v {YOUR-CONFIG-PATH}:/config permify/permify:0.0.1 3. Test your connection. + Create an HTTP GET request ~ localhost:3476/v1/status/ping With docker desktop Setup docker desktop, and run service with the following steps; 1. Open your docker account. 2. Open terminal and run following line docker pull permify/permify:0.0.1 3. Open images, and find Permify. 4. Run Permify with the following credentials (optional setting) + Container Name: authorization-container Ports + Local Host: 3476 Volumes + Host Path: choose the config file and folder + Container Path: /config 5. Test your connection. + Create an HTTP GET request ~ localhost:3476/v1/status/ping Why Permify? You can use Permify any stage of your development for your authorization needs but Permify works best: * If you need to refactor your authorization. * If you're managing authorization for growing micro-service infrastructure. * If your authorization logic is cluttering your code base. * If your data model is getting too complicated to handle your authorization within the service. * If your authorization is growing too complex to handle within code or API gateway. Features * Sync & coordinate your authorization data hassle-free. * Get Boolean - Yes/No decision returns. * Store your authorization data in-house with high availability & low latency. * Easily model, debug & refactor your authorization logic. * Enforce authorizations with a single request anywhere you call it. * Low latency with parallel graph engine for enforcement check. Example Permify helps you move & sync authorization data from your ListenDB to WriteDB with a single config file based on your authorization model that you provide us in a YAML schema. After configuration, you can check authorization with a simple call. Request { "user": "1", "action": "push", "object": "repository:1" } Response { "can": true, "debug": "user 1 is a owner of organization 1" } The Graph of Relations The relation tuples of the ACL used by Permify can be represented as a graph of relations. This graph will help you understand the performance of check engine and the algorithms it uses. filled graph this graph is created by combining schema file and data. API Check Returns a decision about whether user can perform an action on a certain resource. For example, can the user do push on a repository object? Path: POST /v1/permissions/check Required Argument Type Default Description the user or user set who wants to [x] user string - take the action. Examples: "1", "organization:1#owners" [x] action string - the action the user wants to perform on the resource [x] object string - name and id of the resource. Example: "organization:1" [ ] depth integer 8 Example Request { "user": "1", "action": "push", "object": "repository:1" } Response { "can": true, "debug": "user 1 is a owner of organization 1" } Write Custom Tuple We examined how we created the tuple by listening to the tables. Permify allows to create custom tuples. Path: POST /v1/relationships/ write Required Argument Type Default Description [x] entity string - [x] object_id string - [x] relation string - [ ] userset_entity string - [x] userset_object_id string - [ ] userset_relation string - Example Request { "entity": "organization", "object_id": "1", "relation": "admin", "userset_entity": "", "userset_object_id": "1", "userset_relation": "" } Response { "message": "success" } Delete Tuple Delete relation tuple. Path: POST /v1/relationships/delete Required Argument Type Default Description [x] entity string - [x] object_id string - [x] relation string - [ ] userset_entity string - [x] userset_object_id string - [ ] userset_relation string - Example Request { "entity": "organization", "object_id": "1", "relation": "admin", "userset_entity": "", "userset_object_id": "1", "userset_relation": "" } Response { "message": "success" } Client SDKs We are building SDKs to make installation easier, leave us a feedback on which SDK we should build first.
