一、服务端

下载jar包

wget https://github.com/alibaba/arthas/releases/download/arthas-all-3.5.5/arthas-tunnel-server-3.5.5-fatjar.jar

构建镜像

cat > Dockerfile <<'EOF'
FROM openjdk:11.0.13-slim
COPY arthas-tunnel-server-3.5.5-fatjar.jar /opt/
EXPOSE 8080/tcp
WORKDIR /opt
ENTRYPOINT "/bin/sh" "-c" "java -jar arthas-tunnel-server-3.5.5-fatjar.jar"
EOF

docker build -t arthas-tunnel-server:v3.5.5 .

部署至k8s

cat > arthas-tunnel-server.yaml <<'EOF'

EOF

kubectl apply -f arthas-tunnel-server.yaml

通过slb将端口映射至外网

30832 --> 30832
30852 --> 7777

二、agent

进入pod

kubectl exec -it <pod> -c <container> -n <ns> -- bash

下载arthas

curl -O https://arthas.aliyun.com/arthas-boot.jar

安装依赖

rm -fr /var/cache/apk
mkdir -p mkdir /var/cache/apk
apk update
apk add gcc

运行

java -jar arthas-boot.jar  --tunnel-server 'ws://arthas-tunnel-server:7777/ws' --target-ip 0.0.0.0 --app-name <app name>

三、访问

浏览器打开

ip:30832/apps.html
