Dapr进阶-01-Debug dapr

本文主要是介绍Dapr进阶-01-Debug dapr，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. 安装golang

2. 以debug模式编译源码

2.1. 下载dapr源码

git clone https://github.com/dapr/dapr.git

2.2. 目录定位

cd dapr

2.3. 修改Dockerfile中的GOPROXY为国内镜像源

vi ./docker/Dockerfile-debug

• 关键参数如下 

GOPROXY=https://goproxy.cn,direct

• 结果 

2.4. 编译

make release GOOS=linux GOARCH=amd64 DEBUG=1

3. 生成debug模式的dapr镜像到你自己的docker库

3.1. 登录你的docker hub

docker login

3.2. 提前下载gcr.io的docker镜像

gcr.io/distroless/static:nonroot

国内无法访问gcr.io的解决办法_敦格-CSDN博客国内无法访问gcr.io的解决办法https://shuaihj.blog.csdn.net/article/details/123022325

3.3. 验证本地docker镜像

docker images | grep static

3.4. Build 并 Push到docker hub

export DAPR_TAG=dev
export DAPR_REGISTRY=k8schina
make docker-push DEBUG=1

3.5. 验证docker hub

4. 安装debug模式的的dapr

4.1. 创建values.yaml文件

vi values.yaml

global:registry: docker.io/k8schinatag: "dev-linux-amd64"logAsJson: true
dapr_operator:debug:enabled: true
dapr_sidecar_injector:hostNetwork: truedebug:enabled: true
dapr_placement:debug:enabled: true
dapr_sentry:debug:enabled: true

4.2. 卸载旧版本

helm uninstall dapr --namespace dapr-system

4.3. 安装debug版本

• 必须 进入dapr源码目录

cd dapr

• 自定义安装 

helm install dapr charts/dapr \
--namespace dapr-system \
--create-namespace \
--values values.yaml \
--wait

4.4. 验证

docker images | grep dev

5. Debug Dapr 控制面组件

5.1. 查看要debug的控制面pod

kubectl get pods -n dapr-system -o wide

5.2. debug监控你的控制面pod

kubectl port-forward dapr-operator-7878f94fcd-6bfx9 40000:40000 -n dapr-system

6. Debug 微服务的 daprd sidecar

6.1. 配置你的deployment为可debug

dapr.io/enable-debug: "true"

apiVersion: v1
kind: Namespace
metadata:name: dapr-demo
---
apiVersion: apps/v1
kind: Deployment
metadata:name: service01namespace: dapr-demolabels:app: service01
spec:replicas: 2selector:matchLabels:app: service01template:metadata:labels:app: service01annotations:dapr.io/enabled: "true"dapr.io/app-id: "service01"dapr.io/app-port: "80"dapr.io/sidecar-liveness-probe-delay-seconds: "10"dapr.io/sidecar-readiness-probe-delay-seconds: "10"dapr.io/log-as-json: "true"dapr.io/enable-debug: "true"spec:containers:- name: service01image: docker.io/k8schina/service01:v1ports:- containerPort: 80imagePullPolicy: Always

6.2. 部署你的微服务

kubectl apply -f http://k8schina.corecore.cn/DaprDemo.yaml

6.3. 查看要debug的微服务pod

kubectl get pods -n dapr-demo -o wide

6.4. debug监控你的目标pod

kubectl port-forward dapr-operator-7878f94fcd-6bfx9 40000:40000 -n dapr-demo
