#### 一、helm安装skywalking ##### 下载skywalking-kubernetes ```sh $ git clone https://github.com/apache/skywalking-kubernetes.git ``` ##### 配置skywalking ```bash $ cd skywalking-kubernetes/chart $ vim skywalking/values-my-es.yaml ``` ```yaml oap: image: tag: 8.7.0-es7 # Set the right tag according to the existing Elasticsearch version storageType: elasticsearch7 ui: image: tag: 8.7.0 elasticsearch: enabled: false config: # For users of an existing elasticsearch cluster,takes effect when `elasticsearch.enabled` is false host: es-cn-xxxxx.elasticsearch.aliyuncs.com port: http: 9200 user: "elastic" # [optional] password: "xxxxxx" # [optional] ``` ##### helm安装 ```bash $ export SKYWALKING_RELEASE_NAME=skywalking $ export SKYWALKING_RELEASE_NAMESPACE=default $ export REPO=skywalking $ helm repo add ${REPO} https://apache.jfrog.io/artifactory/skywalking-helm $ helm repo update $ helm install "${SKYWALKING_RELEASE_NAME}" ${REPO}/skywalking -n "${SKYWALKING_RELEASE_NAMESPACE}" -f ./values-my-es.yaml ``` #### 二、微服务配置skywalking代理 制作skywalking-agent-sidecar镜像(`微服务的初始化容器`) 下载skywalking-agent ```bash $ cd /opt/skywalking $ wget https://dlcdn.apache.org/skywalking/8.7.0/apache-skywalking-apm-es7-8.7.0.tar.gz #es7表示elasticsearch 7 $ tar xvf apache-skywalking-apm-es7-8.7.0.tar.gz $ cd apache-skywalking-apm-bin-es7/agent $ /bin/cp -r optional-plugins/* plugins/ -f #注意：springboot gateway需要执行该操作，其他springboot微服务不需要 ``` 创建Dockerfile ```bash $ cat Dockerfile ``` ```bash FROM busybox:latest ENV LANG=C.UTF-8 RUN set -eux && mkdir -p /usr/skywalking/agent add apache-skywalking-apm-bin-es7/agent /usr/skywalking/agent WORKDIR / ``` 生成镜像 ```bash $ docker build . -t skywalking-agent-sidecar:8.7.0-fixbug-1 ``` 修改deployment.yaml ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: {{ include "springboot-demo.fullname" . }} labels: {{- include "springboot-demo.labels" . | nindent 4 }} spec: {{- if not .Values.autoscaling.enabled }} replicas: {{ .Values.replicaCount }} {{- end }} selector: matchLabels: {{- include "springboot-demo.selectorLabels" . | nindent 6 }} template: metadata: {{- with .Values.podAnnotations }} annotations: {{- toYaml . | nindent 8 }} {{- end }} labels: {{- include "springboot-demo.selectorLabels" . | nindent 8 }} spec: {{- with .Values.imagePullSecrets }} imagePullSecrets: {{- toYaml . | nindent 8 }} {{- end }} serviceAccountName: {{ include "springboot-demo.serviceAccountName" . }} securityContext: {{- toYaml .Values.podSecurityContext | nindent 8 }} initContainers: #增加初始化容器skywalking - name: {{ .Values.image3.name }} image: "{{ .Values.image3.repository }}:{{ .Values.image3.tag }}" imagePullPolicy: IfNotPresent command: ["sh"] args: [ "-c", "mkdir -p /skywalking/agent && cp -r /usr/skywalking/agent/* /skywalking/agent", ] volumeMounts: - mountPath: /skywalking/agent name: sw-agent containers: - name: {{ .Values.image2.name }} image: "{{ .Values.image2.repository }}:{{ .Values.image2.tag }}" imagePullPolicy: {{ .Values.image.pullPolicy }} command: - "/bin/sh" args: - "-c" - "filebeat -c /etc/filebeat/filebeat.yml" volumeMounts: - name: app-logs mountPath: /log - name: filebeat-{{.Release.Name}}-config mountPath: /etc/filebeat/ - name: {{ .Chart.Name }} securityContext: {{- toYaml .Values.securityContext | nindent 12 }} image: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}" imagePullPolicy: {{ .Values.image.pullPolicy }} env: - name: JAVA_TOOL_OPTIONS #微服务启动参数增加javaagent:skywalking-agent.jar value: -javaagent:/usr/skywalking/agent/skywalking-agent.jar - name: SW_AGENT_NAME #skywalking的名字 value: {{.Release.Name}} - name: SW_AGENT_COLLECTOR_BACKEND_SERVICES #skywalking后端服务的地址:q!
