skywalking架构及简介
官网:https://github.com/apache/skywalking
简介
Java, .NET Core, NodeJS, PHP, and Python auto-instrument agents.
Go and C++ SDKs.
LUA agent especially for Nginx, OpenResty and Apache APISIX.
Browser agent.
Service Mesh Observability. Control panel and data panel.
Metrics system, including Prometheus, OpenTelemetry, Spring Sleuth(Micrometer), Zabbix.
Logs.
Zipkin v1/v2 trace.(No Analysis)
编写OAP和UI资源文件
其中,使用的镜像:
apache/skywalking-oap-server:8.6.0-es7
apache/skywalking-ui:8.6.0
apiVersion: v1
kind: Service
metadata:
name: ui
namespace: skywalking
labels:
service: ui
spec:
ports:
- port: 8080
name: page
nodePort: 30123
selector:
app: ui
type: NodePort
apiVersion: apps/v1
kind: Deployment
metadata:
name: ui-deployment
namespace: skywalking
labels:
app: ui
spec:
replicas: 1
selector:
matchLabels:
app: ui
template:
metadata:
labels:
app: ui
spec:
containers:
- name: ui
image: 192.168.117.160/apache/skywalking-ui:8.6.0
imagePullPolicy: IfNotPresent
ports:
- name: page
containerPort: 8080
env:
- name: SW_OAP_ADDRESS
value: oap:12800
部署OAP和UI
创建名称空间:kubectl create ns skywalking
查看名称空间:kubectl get ns
应用资源文件:kubectl apply -f .
看名称空间下所有资源:kubectl get all -n skywalking
使用skywalking agent
这里,我们不修改服务镜像,通过共享volumes的方式,使agent能被服务镜像访问并使用
下载镜像:skywalking-agent-sidecar:v1.0
推送到本地镜像仓库
资源yaml文件中,添加初始化容器
initContainers:
- image: 192.168.117.160/skywalking/skywalking-agent-sidecar:v1.0
name: sw-agent-sidecar
imagePullPolicy: IfNotPresent
command: ["sh"]
args:
[
"-c",
"mkdir -p /skywalking/agent && cp -r /usr/skywalking/agent/* /skywalking/agent",
]
volumeMounts:
- mountPath: /skywalking/agent
name: sw-agent
资源yaml文件中,服务容器添加环境变量和volumeMounts
env:
- name: JAVA_OPTS
value: -javaagent:/usr/skywalking/agent/skywalking-agent.jar
volumeMounts:
- mountPath: /usr/skywalking/agent
name: sw-agent
部署服务,这样,服务启动的时候,就会加上上面的变量
进入容器:kubectl exec -it product-78fcbdfd6b-mv2hl -n mm -- sh
可以看到,服务容器的目录下有skywalking-agent.jar
