helm部署skywalking链路追踪 java

添加helm仓库 skywalking

取别名 sw 名称可以任意写

powershell 复制代码

helm repo add sw https://apache.jfrog.io/artifactory/skywalking-helm
helm repo list

这里 sw 要与上面的 sw 名称一样

从 Helm 仓库下载 SkyWalking 的 Chart 包，--untar 并自动解压到当前目录

powershell 复制代码

helm pull sw/skywalking --untar

进目录

powershell 复制代码

cd skywalking/

安装 skywalking

下面示例是用的生产的 sky.yaml 配置

直接运行会报错先替换掉所有的 v1beta1

powershell 复制代码

grep -r v1beta1
find . -type f -exec sed -i 's/v1beta1/v1/g' {} \;
helm install skywalking . --namespace skywalking --create-namespace -f sky.yaml

就可以通过节点ip+端口访问页面

客户端deploy yaml 的配置

要实现收集数据需要修改 yaml 主要是改下面3段

如果配置以后启动不了看下是否是 limit的cpu限制导致的可以适当调大limit

下面是3段参数

yaml 复制代码

      volumes:
      - name: skywalking-agent
        emptyDir: {}
      initContainers:
      - name: sw-agent-download
        image: apache/skywalking-java-agent:9.6.0-java17
        command: ["cp", "-r", "/skywalking/agent", "/target/"]
        volumeMounts:
        - name: skywalking-agent
          mountPath: /target

yaml 复制代码

        - name: JAVA_TOOL_OPTIONS
          value: "-javaagent:/skywalking/agent/skywalking-agent.jar -Dskywalking.agent.service_name=demo-app -Dskywalking.collector.backend_service=skywalking-oap.skywalking.svc.cluster.local:11800"

yaml 复制代码

        volumeMounts:
        - name: skywalking-agent
          mountPath: /skywalking
