Elasticsearch 部署
Skywalking OAP Server 会将数据存储到 Elasticsearch 中，并通过 Elasticsearch 进行数据查询和分析。Elasticsearch 安装请参考 https://www.jianshu.com/p/d038540736bc
设置环境变量
# 配置安装helm软件的名称
export SKYWALKING_RELEASE_NAME=skywalking
# 配置skywalking安装到k8s的命名空间
export SKYWALKING_RELEASE_NAMESPACE=kube-ops
# 配置helm仓库名称
export REPO=skywalking
helm添加仓库
$ helm repo add ${REPO} https://apache.jfrog.io/artifactory/skywalking-helm
把skywalking安装包拉取下来
helm pull ${REPO}/skywalking --untar
修改values.yaml
镜像地址可以改成https://hub.docker.com上的地址
cp values.yaml{,.bak}
vim values.yaml
elasticsearch:

config:
host: elasticsearch-master-headless.kube-ops #es地址

部署&&升级
## 安装部署
$ helm install skywalking skywalking -n kube-ops --values ./skywalking/values.yaml
## 更新
$ helm upgrade skywalking skywalking -n kube-ops --values ./skywalking/values.yaml
## 卸载
$ helm uninstall skywalking -n kube-ops
查看部署情况
$ kubectl get all -n kube-ops

配置ingress访问web

kind: Ingress

skywalking数据删除策略
默认为3天
cat /skywalking/config/application.yml |grep recordDataTTL
recordDataTTL: ${SW_CORE_RECORD_DATA_TTL:3} # Unit is day
可以在deployment.yaml中通过env修改为30天
{{- end }}
env:
- name: JAVA_OPTS
value: "-Dmode=no-init {{ .Values.oap.javaOpts }}"
- name: SW_CLUSTER
value: kubernetes
- name: SW_CLUSTER_K8S_NAMESPACE
value: "{{ .Release.Namespace }}"
- name: SW_CORE_RECORD_DATA_TTL
value: "30"
然后更新helm
helm upgrade skywalking -n kube-ops ./skywalking
查看是否生效
进入pod 执行 echo $SW_CORE_RECORD_DATA_TTL
