SkyWalking集成
服务端部署
SkyWalking ShowCase
拉取git https://github.com/apache/skywalking-showcase.git docker 部署 make deploy.docker K8s 部署 make deploy.kubernetes ps: 部署时可指定 FEATURE_FLAGS=single-node,grafana,agent ui "General Service" 加载不了的话就部署上 grafana 能看到 jvm 相关信息和请求图表，docker部署比较方便，agent只能docker部署时指定，它会启动一起agent服务创造数据
SkyWalking Helm
git拉取
https://github.com/apache/skywalking-helm.git
根据下面的values调整一下进行部署
https://github.com/apache/skywalking-helm/blob/master/chart/skywalking/values.yaml
主要调整内容：（没ES把enabled改为true就成config去掉）
oap:
image:
tag: 10.1.0
storageType: elasticsearch
replicas: 1
ui:
image:
tag: 10.1.0
elasticsearch:
enabled: false
config: # For users of an existing elasticsearch cluster,takes effect when `elasticsearch.enabled` is false
host: elasticsearch-master.elk.svc.cluster.local
port:
http: 9200
user: "elastic" # [optional]
password: "elasticsearch123" # [optional]
部署：
export SKYWALKING_RELEASE_VERSION=4.7.0 # change the release version according to your need
export SKYWALKING_RELEASE_NAME=skywalking # change the release name according to your scenario
export SKYWALKING_RELEASE_NAMESPACE=skywalking
helm install "${SKYWALKING_RELEASE_NAME}" \
oci://registry-1.docker.io/apache/skywalking-helm \
--version "${SKYWALKING_RELEASE_VERSION}" \
-n "${SKYWALKING_RELEASE_NAMESPACE}" \
-f ./values-my-es.yaml
PS: K8s用这个部署方式比较好，showcase好像有啥毛病来着，而且它是用于展示的示例部署方式
客户端部署
本地部署
下载agant 9.4.0的，要别的版本或者客户端可下载 解压后调整运行jar命令： java -javaagent:path/skywalking-agent/skywalking-agent.jar \ -Dskywalking.agent.service_name=trip \ -Dskywalking.collector.backend_service=172.22.8.15:11800 -jar app.jar Idea添加运行参考Add VM Options: -javaagent:path/skywalking-agent/skywalking-agent.jar -Dskywalking.agent.service_name=xxx -Dskywalking.collector.backend_service=172.22.8.15:11800 -Dskywalking.agent.namespace=prod
K8s 部署
握草，发现它有给image，不过自己做定制化也高 制作image： 下载： https://www.apache.org/dyn/closer.cgi/skywalking/java-agent/9.4.0/apache-skywalking-java-agent-9.4.0.tgz 解压 tar -zxvf apache-skywalking-java-agent-9.4.0.tgz 创建dockerfile写入： FROM busybox ADD skywalking-agent /skywalking-agent 没登录先docker login下 docker build -t your-image-store/namespace/skywalking-agent-gateway:9.4.0 docker push your-image-store/namespace/skywalking-agent-gateway:9.4.0 PS: build前看看需要哪些插件，从options-plugin mv to plugin 部署k8s
