cerbos minio s3 存储试用

标签：3592 minio s3 env cerbos policies

cerbos 支持blob 存储，以下是关于minio s3 的集成试用

环境准备

• docker-compose

version: "3"

services:

    minio:

       image: minio/minio

       ports:

         - "9000:9000"

         - "9001:9001"

       command: server /data --console-address ":9001"

       environment:

         MINIO_ACCESS_KEY: minio

         MINIO_SECRET_KEY: minio123

    cerbos:

       image:  ghcr.io/cerbos/cerbos:latest

       volumes:

         - ./policies:/policies

         - ./config:/config

       env_file:

       - ./.env

       command: server --config=/config/conf.yaml

       ports:

         - "3592:3592"

         - "3593:3593"

    cerbos-compile:

       profiles:

         - compile

       image:  ghcr.io/cerbos/cerbos:latest

       volumes:

         - ./policies:/policies

       command: compile /policies

       env_file:

       - ./.env

       ports:

         - "3594:3592"

         - "3595:3593"

• 配置
  conf.yaml

 

---

server:

  httpListenAddr: ":3592"

  grpcListenAddr: ":3593"

 

# storage:

#   driver: "disk"

#   disk:

#     directory: /policies

#     watchForChanges: true

 

storage:

  driver: "blob"

  blob:

    # aws golang sdk minio 参考配置

    bucket: "s3://demoapp-cerbos/policies?endpoint=minio:9000&disableSSL=true&s3ForcePathStyle=true&region=us-east-1"

    prefix: policies

    workDir: ${HOME}/tmp/cerbos/work

    updatePollInterval: 15s

    downloadTimeout: 30s

    requestTimeout: 10s

环境变量.env
主要是s3 需要的

 

AWS_ACCESS_KEY_ID=minio

AWS_SECRET_ACCESS_KEY=minio123

• s3策略
  直接创建对应的demoapp-cerbos bucket 并创建一个policies 的path，内容如下

 

---

apiVersion: api.cerbos.dev/v1

resourcePolicy:

  version: default

  resource: contact

  rules:

  - actions: ["*"]

    effect: EFFECT_ALLOW

    roles:

      - admin    

  - actions: ["read", "create"]

    effect: EFFECT_ALLOW

    roles:

      - user

    condition:

      match:

          expr: request.principal.attr.department == "Sales"

 

  - actions: ["update", "delete"]

    effect: EFFECT_ALLOW

    roles:

      - user

    condition:

      match:

          expr: request.resource.attr.ownerId == request.principal.id

 

s3 效果

 

代码集成测试

还是以前的nodejs 代码

 

const { HTTP } = require("@cerbos/http");

 

const cerbos = new HTTP("http://localhost:3592");

 

const demo = async function () {

    let result = await cerbos.isAllowed({

        principal: {

            id: "[email protected]",

            roles: ["user"],

            attr: { department: "Sales" },

        },

        resource: {

            kind: "contact",

            id:"333",

            attr: { ownerId: "[email protected]" },

        },

        action: "delete",

    });

    console.log(result)

}

 

demo()

• 效果

 

说明

cerbos 对于s3 的支持有几个配置参数（拉取时间），同时还会包含cache 所以使用的时候需要注意
