1、k8s中安装部署 skywalking
skywalking集群情况下需要保证用同一数据源,这里我们存储方式改为es
1.1 部署elasticsearch
docker run -it -d -p 9200:9200 -p 9300:9300 -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -e "discovery.type=single-node" elasticsearch:7.14.2
1.2 创建skywalking-oap的yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: skywalking-oap
namespace: default
labels:
app: skywalking-oap
spec:
replicas: 1
selector:
matchLabels:
app: skywalking-oap
template:
metadata:
labels:
app: skywalking-oap
spec:
containers:
- env:
- name: SW_STORAGE
value: elasticsearch7 ##存储方式
- name: SW_STORAGE_ES_CLUSTER_NODES
value: 10.0.24.5:9200 ##es地址
name: skywalking-oap
image: apache/skywalking-oap-server:8.4.0-es7 ##镜像
imagePullPolicy: IfNotPresent ##如果存在就不拉去取
ports:
- containerPort: 11800
name: grpc
- containerPort: 12800
name: rest
---
apiVersion: v1
kind: Service
metadata:
name: skywalking-oap
namespace: default
labels:
service: skywalking-oap
spec:
ports:
- port: 12800
name: rest
- port: 11800
name: grpc
selector:
app: skywalking-oap
1.3 创建skywalking-ui的yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: skywalking-ui
namespace: default
labels:
app: skywalking-ui
spec:
replicas: 1
selector:
matchLabels:
app: skywalking-ui
template:
metadata:
labels:
app: skywalking-ui
spec:
containers:
- name: skywalking-ui
image: apache/skywalking-ui:8.4.0
ports:
- containerPort: 8080
name: page
env:
- name: SW_OAP_ADDRESS
value: skywalking-oap:12800 ##skywalking-oap监听端口
---
apiVersion: v1
kind: Service
metadata:
name: skywalking-ui
namespace: default
labels:
service: skywalking-ui
spec:
ports:
- port: 8080
name: page
nodePort: 30200
type: NodePort
selector:
app: skywalking-ui
1.3 k8s中部署 skywalking-oap.yaml、skywalking-ui.yaml
kubectl create -f skywalking-oap.yaml
kubectl create -f skywalking-ui.yaml
1.4 查看skywalking-ui
2、部署项目使用skywalking进行链路追踪
2.1 下载 skywalking-agent
https://skywalking.apache.org/downloads/#Agents
2.2 idea 中使用skywalking-agent
2.2.1 创建项目server-order 并创建web控制层
@RestController
public class OrderController {
@GetMapping("/getuuid")
public String getuuid(){
String uuid = UUID.randomUUID().toString().replace("-", "");
return uuid;
}
}
2.2.2 创建项目web-monitor 并创建feign和monitor的控制层
@FeignClient(value = "server-order")
@Component
public interface OrderService {
@GetMapping("/getuuid")
public String getuuid();
}
@RestController
public class MonitorController {
@Autowired
private OrderService orderService;
@GetMapping("send")
public String send(){
String getuuid = orderService.getuuid();
return getuuid;
}
}
2.2.3 增加环境变量
-javaagent:D:\opts\apache-skywalking-java-agent-8.8.0\skywalking-agent\skywalking-agent.jar
-Dskywalking.collector.backend_service=ip地址:端口
-Dskywalking.agent.service_name=服务名称
2.2.3 查看skywalking-ui链路

2.3 k8s 部署项目增加skywalking链路追踪
2.3.1 构建镜像
FROM java:8
WORKDIR /project
ENV JAVA_OPTS=""
ENV SKYWALKING_OPTS=""
CPOY skywalking-agent.jar skywalking-agent.jar
COPY web-monitor.jar web-monitor.jar
ENTRYPOINT ["sh","-c","java -jar ${JAVA_OPTS} web-monitor.jar ${SKYWALKING_OPTS} "]
2.3.2 创建k8s无状态服务
apiVersion: extensions/v1beta1 #版本
kind: Deployment #资源类型
metadata:
labels:
workload.user.cattle.io/workloadselector: deployment-cloud-web-monitor #标签,k8s对于资源控制主要是根据labels和selector进行的
name: web-monitor #资源名称
namespace: deafult #所属命名空间
spec:
progressDeadlineSeconds: 600
replicas: 1 #一个pod
revisionHistoryLimit: 10
selector:
matchLabels:
workload.user.cattle.io/workloadselector: deployment-cloud-web-monitor
strategy:
rollingUpdate:
maxSurge: 1
maxUnavailable: 0
type: RollingUpdate #发布策略
template: #创建模板
metadata:
labels:
workload.user.cattle.io/workloadselector: deployment-cloud-web-monitor
spec:
containers:
- env:
- name: JAVA_OPTS
value: -Xmx3550M -Xms3550M -Xmn2G -Xss256k
- name: SKYWALKING_OPTS
value: -javaagent:./skywalking-agent.jar -Dskywalking.agent.service_name=web-monitor -Dskywalking.collector.backend_service=skywalking-oap:11800
image: 192.1.1.1/project/web-monitor:stable #镜像
imagePullPolicy: Always #镜像拉取策略
name: web-monitor #容器名称
ports:
- containerPort: 8513 #暴露端口
name: 8513tcp02
protocol: TCP
resources:
limits:
memory: 4Gi
stdin: true
terminationMessagePath: /dev/termination-log
terminationMessagePolicy: File
tty: true
volumeMounts:
- mountPath: /log #容器内部挂载位置
name: vol1
dnsPolicy: ClusterFirst
restartPolicy: Always #重启策略
schedulerName: default-scheduler
securityContext: {}
terminationGracePeriodSeconds: 30
volumes:
- name: vol1
persistentVolumeClaim: #挂载的pvc
claimName: log-pvc
2.3.3 注意点
在上边的镜像中 将skywalking-agent.jar 拷贝到镜像里,这一步可以使用pv挂载,另外也可以将skywalking-agent用initc来做链路追踪文章来源地址https://www.toymoban.com/news/detail-782574.html
