Overview

stream stack 是一个用于提供流式数据存储的服务 目前还在开发阶段

架构

安装

安装k8s集群(如果没有)

wget -O kind-cluster.yaml https://raw.githubusercontent.com/stream-stack/store-operator/main/config/samples/kind-cluster.yaml
kind create cluster --config kind-cluster.yaml --name c1

该命令使用kind创建了1个master,3个node节点的k8s集群 因storeset会使用localpersistent volume来存储数据,所以需要在k8s集群中创建localpersistent volume 文件夹

docker exec -it c1-worker mkdir -p /data
docker exec -it c1-worker2 mkdir -p /data
docker exec -it c1-worker3 mkdir -p /data

安装cert-manager

kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.7.1/cert-manager.yaml

安装operator

kubectl apply -f https://raw.githubusercontent.com/stream-stack/store-operator/main/deploy/operator-install.yaml

使用

创建存储事件的storeset

kubectl apply -f https://raw.githubusercontent.com/stream-stack/store-operator/main/config/samples/core_v1_storeset.yaml

该命令创建了一个storeset,该storeset的名称为test,label为test,后续的broker和subscription都会使用该storeset

创建broker

kubectl apply -f https://raw.githubusercontent.com/stream-stack/store-operator/main/config/samples/knative_v1_broker.yaml

该命令创建了一个broker,该broker的名称为test,label为test,后续的subscription都会使用该broker

创建事件接收容器

kubectl apply -f https://raw.githubusercontent.com/stream-stack/store-operator/main/config/samples/display.yaml

该命令创建了一个事件接收容器,用来接收标准的cloudevents事件,并在日志中显示 可通过kubectl logs -f hello-display查看日志

创建subscription

kubectl apply -f https://raw.githubusercontent.com/stream-stack/store-operator/main/config/samples/knative_v1_subscription.yaml

发送事件

获取broker地址

kubectl  get svc test-dispatcher
###样例输出
NAME              TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)   AGE
test-dispatcher   ClusterIP   10.96.150.185   <none>        80/TCP    38m

其中10.96.150.185为broker的地址,可以通过该地址发送事件

curl -X POST -v --location "http://10.96.150.185" \
    -H "Content-Type: application/json" \
    -H "Ce-Id: 1" \
    -H "Ce-Specversion: 1.0" \
    -H "Ce-Type: test" \
    -H "Ce-Source: testSource" \
    -H "Content-Type: application/json" \
    -d "{
          \"test\":1
        }"

curl -X POST -v --location "http://10.96.150.185" \
    -H "Content-Type: application/json" \
    -H "Ce-Id: 2" \
    -H "Ce-Specversion: 1.0" \
    -H "Ce-Type: test" \
    -H "Ce-Source: testSource" \
    -H "Content-Type: application/json" \
    -d "{
          \"test\":2
        }"

通过kubectl logs -f hello-display 查看日志

卸载
