kind: Component
metadata:name: statestore
spec:type: state.redisversion: v1metadata:- name: redisHostvalue: redis:6379- name: redisPasswordvalue: - name: actorStateStorevalue: true- name: keyPrefixvalue: appid2、通过order访问pay设置的key访问不到数据3、查看redis中的keys以各服务的appid作为前缀name模式1、statestore.yamlapiVersion: dapr.io/v1alpha1
kind: Component
metadata:name: statestore
spec:type: state.redisversion: v1metadata:- name: redisHostvalue: redis:6379- name: redisPasswordvalue: - name: actorStateStorevalue: true- name: keyPrefixvalue: name2、通过order访问pay设置的key能访问到数据3、查看redis中的keys有状态存储的名称作为前缀多个name的情况该如何实现呢下面是order服务和pay服务分别有自己的组件配置文件文件夹分别是components_ordercomponents_pay状态组件的名称分别是statestore_order和statestore_pay参见下面的配置文件。1、docker-compose.ymlversion: 3.4services:#┌────────────────────────────────┐#│ ordersystem app Dapr sidecar │#└────────────────────────────────┘ordersystem:image: ${DOCKER_REGISTRY-}ordersystemdepends_on:- redis- placementbuild:context: ../dockerfile: /OrderSystem/Dockerfileports:- 3500:3500volumes: - ../OrderSystem:/OrderSystem networks:- b2c-daprordersystem-dapr:image: daprio/daprd:latestcommand: [ ./daprd, -app-id, order, -app-port, 80,-placement-host-address, placement:50006,-components-path,/components]build:context: ../depends_on:- ordersystemnetwork_mode: service:ordersystemvolumes: - ../components_order:/components #┌─────────────────────────┐#│ Dapr placement1 service │#└─────────────────────────┘ placement:image: daprio/daprcommand: [./placement, -port, 50006]ports:- 50006:50006networks:- b2c-dapr#┌────────────────────┐#│ Redis1 state store │#└────────────────────┘ redis:image: redis:latestports:- 6380:6379networks:- b2c-dapr################################################################################################################### #┌───────────────────────────────────┐#│ paymentsystem1 app Dapr sidecar │#└───────────────────────────────────┘ paymentsystem1:image: ${DOCKER_REGISTRY-}paymentsystemdepends_on:- redis- placementbuild:context: ../dockerfile: /PaymentSystem/Dockerfileports:- 3601:3500volumes: - ../PaymentSystem:/PaymentSystem networks:- b2c-dapr paymentsystem1-dapr:image: daprio/daprd:latestcommand: [ ./daprd, -app-id, pay, -app-port, 80,-placement-host-address, placement:50006,-components-path,/components ]build:context: ../depends_on:- paymentsystem1network_mode: service:paymentsystem1volumes: - ../components_pay:/components #┌───────────────────────────────────┐#│ paymentsystem2 app Dapr sidecar │#└───────────────────────────────────┘ paymentsystem2:image: ${DOCKER_REGISTRY-}paymentsystemdepends_on:- redis- placement build:context: ../dockerfile: /PaymentSystem/Dockerfilevolumes: - ../PaymentSystem:/PaymentSystem ports:- 3602:3500networks:- b2c-dapr paymentsystem2-dapr:image: daprio/daprd:latestcommand: [ ./daprd, -app-id, pay, -app-port, 80 ,-placement-host-address, placement:50006,-components-path,/components]build:context: ../depends_on:- paymentsystem2network_mode: service:paymentsystem2volumes: - ../components_pay:/components networks:b2c-dapr:2、components_order文件夹下的statstore.yamlapiVersion: dapr.io/v1alpha1
kind: Component
metadata:name: statestore_order
spec:type: state.redisversion: v1metadata:- name: redisHostvalue: redis:6379- name: redisPasswordvalue: - name: actorStateStorevalue: true- name: keyPrefixvalue: name3、components_pay文件夹下的statstore.yamlapiVersion: dapr.io/v1alpha1
kind: Component
metadata:name: statestore_pay
spec:type: state.redisversion: v1metadata:- name: redisHostvalue: redis:6379- name: redisPasswordvalue: - name: actorStateStorevalue: true- name: keyPrefixvalue: name4、通过order访问pay设置的key能访问到数据5、查看redis中的keys有状态存储的名称作为前缀none模式1、statestore.yamlapiVersion: dapr.io/v1alpha1
kind: Component
metadata:name: statestore
spec:type: state.redisversion: v1metadata:- name: redisHostvalue: redis:6379- name: redisPasswordvalue: - name: actorStateStorevalue: true- name: keyPrefixvalue: none2、通过order访问pay设置的key能访问到数据3、查看redis中的keys没有任何前缀dapr通过简单的配置实现了三种状态数据的共享机制方便简捷。所以在使用dapr前就要把各服务的数据共用规划好方便配置使用。
