项目集成SkyWalking，基于k8s搭建

一、搭建SkyWalking

官方文档（英文）：skywalking/docs at master · apache/skywalking

中文可以使用：GitHub - SkyAPM/document-cn-translation-of-skywalking: [已过期,请使用官网AI文档] The CN translation version of Apache SkyWalking document

需要搭建服务：SkyWalkingOAP，SkyWalkingUi, Elastisearch

1.先搭建SkyWalkingOAP服务.

SkyWalkingOAP 负责数据的收集、分析和存储。通过部署oap来启动SkyWalking的基础服务。

1.1首先搭建工作负载：

kind: Deployment
apiVersion: apps/v1
metadata:
name: skywalk-970-oap
namespace: common
labels:
app: skywalk-970-oap
annotations:
deployment.kubernetes.io/revision: '4'
kubesphere.io/creator: fly
spec:
replicas: 1
selector:
matchLabels:
app: skywalk-970-oap
template:
metadata:
creationTimestamp: null
labels:
app: skywalk-970-oap
release: skywalking
annotations:
kubesphere.io/creator: fly
kubesphere.io/restartedAt: '2024-05-22T03:21:09.886Z'
spec:
volumes:
- name: host-time
hostPath:
path: /etc/localtime
type: ''
containers:
- name: oap
image: '159.75.136.188:40080/szqc2023002/skywalking-oap-server:9.7.0'
ports:
- name: grpc
containerPort: 11800
protocol: TCP
- name: rest
containerPort: 12800
protocol: TCP
env:
- name: JAVA_OPTS
value: '-Xmx1g -Xms1g'
- name: SW_CORE_RECORD_DATA_TTL
value: '2'
- name: SW_CORE_METRICS_DATA_TTL
value: '2'
- name: SW_STORAGE
value: elasticsearch
- name: SW_STORAGE_ES_CLUSTER_NODES
value: 'elasticsearch762.common:9200'
resources:
limits:
memory: 2Gi
requests:
memory: 1Gi
volumeMounts:
- name: host-time
readOnly: true
mountPath: /etc/localtime
terminationMessagePath: /dev/termination-log
terminationMessagePolicy: File
imagePullPolicy: IfNotPresent
restartPolicy: Always
terminationGracePeriodSeconds: 30
dnsPolicy: ClusterFirst
securityContext: {}
schedulerName: default-scheduler
strategy:
type: RollingUpdate
rollingUpdate:
maxUnavailable: 25%
maxSurge: 25%
revisionHistoryLimit: 10
progressDeadlineSeconds: 600
我们存储日志的方式是使用es.

1.2然后搭建SkyWalking服务

kind: Service
apiVersion: v1
metadata:
name: skywalk-970-oap
namespace: common
labels:
app: skywalk-970-oap
annotations:
kubesphere.io/creator: fly
spec:
ports:
- name: tcp-11800
protocol: TCP
port: 11800
targetPort: 11800
nodePort: 30876
- name: tcp-12800
protocol: TCP
port: 12800
targetPort: 12800
nodePort: 31012
selector:
app: skywalk-970-oap
release: skywalking
clusterIP: 10.233.43.222
clusterIPs:
- 10.233.43.222
type: NodePort
sessionAffinity: None
externalTrafficPolicy: Cluster
ipFamilies:
- IPv4
ipFamilyPolicy: SingleStack
internalTrafficPolicy: Cluster
至此，SkyWalkingOAP服务完成。

2.搭建SkyWalkingUi服务

SkyWalkibgUi是SkyWalking的可视化界面服务。用于展示分布式系统的监控数据。我们可以通过WebUi来访问和使用SkyWalking。

2.1首先搭建SkyWalkingUi的工作负载

kind: Deployment
apiVersion: apps/v1
metadata:
name: skywalk-970-ui
namespace: common
labels:
app: skywalk-970-ui
annotations:
deployment.kubernetes.io/revision: '4'
kubesphere.io/creator: fly

selector:
matchLabels:
app: skywalk-970-ui
template:
metadata:
creationTimestamp: null
labels:
app: skywalk-970-ui
release: skywalking
annotations:
kubesphere.io/creator: fly
kubesphere.io/restartedAt: '2024-05-22T03:10:50.693Z'
spec:
containers:
- name: sk-ui
image: 'apache/skywalking-ui:9.7.0'
ports:
- containerPort: 8080
protocol: TCP
env:
- name: SW_OAP_ADDRESS
value: 'http://skywalk-970-oap.common:12800'
resources: {}
terminationMessagePath: /dev/termination-log
terminationMessagePolicy: File
imagePullPolicy: IfNotPresent
restartPolicy: Always
terminationGracePeriodSeconds: 30
dnsPolicy: ClusterFirst
securityContext: {}
schedulerName: default-scheduler
strategy:
type: RollingUpdate
rollingUpdate:
maxUnavailable: 25%
maxSurge: 25%
revisionHistoryLimit: 10
progressDeadlineSeconds: 600
2.2搭建SkyWalkingUi服务

kind: Service
apiVersion: v1
metadata:
name: skywalk-970-ui
namespace: common
labels:
app: skywalk-970-ui
annotations:
kubesphere.io/creator: fly
spec:
ports:
- name: http-8080
protocol: TCP
port: 8080
targetPort: 8080
nodePort: 31195
selector:
app: skywalk-970-ui
release: skywalking
clusterIP: 10.233.2.227
clusterIPs:
- 10.233.2.227
type: NodePort
sessionAffinity: None
externalTrafficPolicy: Cluster
ipFamilies:
- IPv4
ipFamilyPolicy: SingleStack
internalTrafficPolicy: Cluster
至此SkyWalkingUi服务搭建完成。

3.搭建Es服务，用于存储SkyWalking日志。

3.1搭建Es服务的工作负载

kind: Deployment
apiVersion: apps/v1
metadata:
name: elasticsearch762
namespace: common
labels:
app: elasticsearch762
annotations:
deployment.kubernetes.io/revision: '4'
kubesphere.io/creator: fly

containerPort: 9300
protocol: TCP
env:

resources: {}
volumeMounts:

readOnly: true
mountPath: /usr/share/elasticsearch/config/elasticsearch.yml
subPath: elasticsearch.yml
- name: volume-vcbpgy
readOnly: true
mountPath: /usr/share/elasticsearch/config/jvm.options
subPath: jvm.options
terminationMessagePath: /dev/termination-log
terminationMessagePolicy: File
imagePullPolicy: IfNotPresent
restartPolicy: Always
terminationGracePeriodSeconds: 30
dnsPolicy: ClusterFirst
nodeSelector:
kubernetes.io/hostname: worker1
serviceAccountName: default
serviceAccount: default
securityContext: {}
schedulerName: default-scheduler
strategy:
type: RollingUpdate
rollingUpdate:
maxUnavailable: 25%
maxSurge: 25%
revisionHistoryLimit: 10
progressDeadlineSeconds: 600
3.2搭建Es的服务

kind: Service
apiVersion: v1
metadata:
name: elasticsearch762
namespace: common
labels:
app: elasticsearch762
annotations:
kubesphere.io/creator: fly
spec:
ports:
- name: tcp-9200
protocol: TCP
port: 9200
targetPort: 9200
- name: tcp-9300
protocol: TCP
port: 9300
targetPort: 9300
selector:
app: elasticsearch762
clusterIP: 10.233.7.71
clusterIPs:
- 10.233.7.71
type: ClusterIP
sessionAffinity: None
ipFamilies:
- IPv4
ipFamilyPolicy: SingleStack
internalTrafficPolicy: Cluster
至此Es搭建服务完成。需要注意的点是：SkyWalkingAOP配置的Es的变量值，要对应Es的Dns服务名称。

- name: SW_STORAGE_ES_CLUSTER_NODES
value: 'elasticsearch762.common:9200'

二、项目集成Skywalking

在需要集成SkyWalking服务的deploy.yml添加initContainer，达到无侵入方式集成。

添加了挂载点：

spec:

- name: skywalking-agent
emptyDir: {}

添加了initContainer

initContainers:
- name: agent-container
image: 'apache/skywalking-java-agent:9.0.0-alpine'
command:
- /bin/sh
args:
- '-c'
- >-
cp -R /skywalking/agent /agent/;cp

resources: {}
volumeMounts:
- name: skywalking-agent
mountPath: /agent
terminationMessagePath: /dev/termination-log
terminationMessagePolicy: File
imagePullPolicy: IfNotPresent

增加了SkyWalking的相关配置：

env:
- name: JAVA_TOOL_OPTIONS
value: '-javaagent:/skywalking/agent/skywalking-agent.jar'
- name: SW_AGENT_NAME
value: zhqc-frame-gateway
- name: SW_AGENT_COLLECTOR_BACKEND_SERVICES
value: '192.168.10.222:30876'
- name: SW_AGENT_TRACE_IGNORE_PATH
value: 'GET:/actuator/**,Lettuce/**'

SkyWalking忽略的接口

- name: SW_AGENT_TRACE_IGNORE_PATH
value: 'GET:/actuator/**,Lettuce/**'

SkyWalking的收集服务，即SkyWalkingAOP暴漏的服务

- name: SW_AGENT_COLLECTOR_BACKEND_SERVICES
value: '192.168.10.222:30876'

部署服务之后，就可以在SKyWalking看到该服务。

三、项目将日志集成到SkyWalking中。

1.引入pom包

<!-- https://mvnrepository.com/artifact/org.apache.skywalking/apm-toolkit-trace -->
<dependency>
   <groupId>org.apache.skywalking</groupId>
   <artifactId>apm-toolkit-trace</artifactId>
   <version>9.0.0</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.apache.skywalking/apm-toolkit-logback-1.x -->

   <groupId>org.apache.skywalking</groupId>
   <artifactId>apm-toolkit-logback-1.x</artifactId>
   <version>9.0.0</version>
</dependency>
  </dependencies>

2.修改logback-spring.xml的配置

<?xml version="1.0" encoding="UTF-8" ?>
<!-- 级别从高到低 OFF 、 FATAL 、 ERROR 、 WARN 、 INFO 、 DEBUG 、 TRACE 、 ALL -->
<!-- 日志输出规则 根据当前ROOT 级别，日志输出时，级别高于root默认的级别时 会输出 -->
<!-- 以下 每个配置的 filter 是过滤掉输出文件里面，会出现高级别文件，依然出现低级别的日志信息，通过filter 过滤只记录本级别的日志 -->
<!-- scan 当此属性设置为true时，配置文件如果发生改变，将会被重新加载，默认值为true。 -->
<!-- scanPeriod 设置监测配置文件是否有修改的时间间隔，如果没有给出时间单位，默认单位是毫秒。当scan为true时，此属性生效。默认的时间间隔为1分钟。 -->
<!-- debug 当此属性设置为true时，将打印出logback内部日志信息，实时查看logback运行状态。默认值为false。 -->
