本来不打算写这块来的,当初觉得这部分相对来说比较简单,主要部署好skywalking-oap server 跟展示端 skywalking-ui就完事了,结果在实际部署过程中发现,通过SSL协议连接ES这块居然是个卡点,搞了半天,网上也没啥文章能照着做通的,唯一让我有实质性帮助的是chatgpt…为了给人类扳回一程,我不得不写下此篇!!
顺便吐槽一下Apache开源体系丰富是丰富,真是有点乱,一个项目一个标准。就ssl通讯这块,ES节点之间主要用的pk12证书,kinbana连ES 变成了pem证书(Java客户端用的应该也是这个),到sktwalking这了又改成用jks证书,就这么点事都不能统一,非得各搞各的,给人感觉像故意体现项目独特性。

k8s部署skywalking的oap server并不是复杂,就一套yml
- service
- statefulset
直接贴出来
service部署
service我照例用的是固定ip
apiVersion: v1
kind: Service
metadata:
name: skywalking-oap-svc
namespace: devops-tools
annotations:
desc : skywalking-oap-server服务访问入口
spec:
selector:
k8s-app: skywalking-oap
type: ClusterIP #type: ClusterIP【默认】 | NodePort | LoadBalancer(外部负载均衡) | ExternalName (外部DNS解析)
clusterIP: 10.106.160.105
ports:
- port: 12800
targetPort: 12800
name: rest
- port: 11800
targetPort: 11800
name: grpc
StatefulSet部署
要点说明
- 与之前一样,为了便于自动部署,我使用jenkions做了文件存储,基于jenkins的账号验证提供初级的文件安全保证,使用initContainers在启动容器前,下载所需的证书,通过配置ENV给容器获取账号、密码,此外还增加禁止下载的ENV变量,以便于在特殊情况下屏蔽下载(比如jenkins 宕机了);
- 完整版的skywalking配置文件太长了,这里我用了几个主要的环境变量做了配置,环境变量完整支持官方文档在这里,可以根据实际需要进行参考配置skywalking-oap server 环境变量支持
- 环境变量使用说明,如何生成jks证书下面会说
- name: SW_STORAGE #声明使用ES做存储
value: "elasticsearch"
- name: SW_NAMESPACE #skywalking 使用的ES索引前缀配置
value: "skywalking-log"
- name: SW_STORAGE_ES_CLUSTER_NODES #集群连接地址
value: "es-01-svc.es:9200"
- name: SW_STORAGE_ES_HTTP_PROTOCOL #集群连接协议,简单点直接用http也不是不行
value: "https"
- name: SW_ES_USER #连接ES集群用户
value: "elastic"
- name: SW_ES_PASSWORD #连接ES集群用户密码
value: "password"
- name: SW_STORAGE_ES_SSL_JKS_PATH #ssl协议证书存储位置
value: "/local-certs/es01_http.jks"
- name: SW_STORAGE_ES_SSL_JKS_PASS #ssl协议证书密码
value: "jks密码"
- name: "SW_STORAGE_ES_SUPER_DATASET_INDEX_SHARDS_FACTOR" #skywalking 索引分片数 默认5
value: "1"
- name: SW_CORE_RECORD_DATA_TTL #skywalking 明细数据存储时长,单位:天,默认3
value: "14"
- name: SW_CORE_METRICS_DATA_TTL #skywalking 统计数据存储时长,单位:天,默认7
value: "30"
- 想要回顾如何部署ES集群可以参考之前的文档 K8S 部署 ES8.12.0

生成JKS证书
登录到要连接的ES集群的任意节点上,使用ES集群的http.p12证书进行生成
注意
- http.p12证书如果有密码的话,需要在-srcstorepass “$http12证书密码"参数中设定,没有也要设为”",不能少参数
- -storepass "jks证书密码"这个密码必须有,哪怕http.p12没有密码,这个证书也要设置至少6位的密码
/usr/share/elasticsearch/jdk/bin/keytool -importkeystore -destkeystore ./es_http.jks -deststoretype JKS -srckeystore /usr/share/elasticsearch/config/local-certs/http.p12 -srcstoretype PKCS12 -storepass "jks证书密码" -srcstorepass "$http12证书密码"
这样skywalking-oap server就部署好了。
skywalking-ui
接下来是skywalking-ui,这个更简单,只要设定好要连接的skywalking-oap server的地址就行了,yml部署文件如下
# api service

kind: Service

skywalking-agent部署
这里一般有2种方式
1.通过init-containers将agent文件部署到容器内,同时在应用启动脚本中添加java-agent JVM参数来实现;
2.将agent文件放置到应用项目中,同时在应用启动脚本中添加java-agent JVM参数来实现
我推荐使用第1种方式,这种方式对项目代码无侵入,具体过程如下:
- 下载skywaling-agent包,下载地址
- 解压缩下载下来的tgz,将里面的skywalking-agent目录重新打包为zip或tar
- 将打好的skywalking-agent的压缩包上传至jenkins
- 在部署应用容器的k8s ymal中init-containers的command中,下载压缩包并解压缩到PVC存储的指定目录中
- 给容器挂载存放agent文件的pvc存储目录
- 在容器启动命令中添加参数,这里以java应用为例
-javaagent:/data/deploy/skywalking-agent/skywalking-agent.jar=agent.service_name=${APP_GROUP}::${APP_NAME},collector.backend_service=skywalking-oap-server:11800,logging.dir=/data/logs,logging.level=warn,logging.max_history_files=10
这里我设定了几个参数
agent.service_name=${APP_GROUP}::${APP_NAME} 【必须设定】当前应用的service名称,可以使用${APP_GROUP}::${APP_NAME}来给服务分组,相同的${APP_GROUP}在skywalking-ui中展示的时候会分到同一组中
collector.backend_service=skywalking-oap-server:11800 【必须设定】 这个没啥好说的
logging.dir=/data/logs,logging.level=warn,logging.max_history_files=10 【可选】设定日志存储位置,级别,最多几个
完整参数支持可以参考官方文档 agent参数配置
一定要注意格式:
-javaagent:/data/deploy/skywalking-agent/skywalking-agent.jar=key:value,key:value
最后再给大家贴一下我的Java 应用容器部署模板片段

- name: init-deploy
