# k8s配置中心實戰-交付apollo三元件 [TOC] ## 1 apollo簡單說明 [官方地址](https://github.com/ctripcorp/apollo) [概念請參考:](http://www.liuhaihua.cn/archives/522960.html) ### 1.1 apollo最簡架構圖：  ### 1.2 apollo元件部署關係 1. configservice自帶eureka註冊中心、配置寫入configDB資料庫、優先部署、為client提供服務 2. adminservice向eureka註冊服務、與configservice共用資料庫、為portal提供服務 3. configservice和adminservice組成一套環境、多個環境就得部署多套config和admin 4. portal是web端、各環境共用、只需部署一套、有自己單獨的資料庫 ## 2 為appllo準備資料庫 apollo需要使用資料庫，如果是mysql，需要版本在5.6以上： 本次環境mysql部署在10.4.7.11上，使用mysql5.7，為測試簡單起見，各環境資料庫使用同一個，不做隔離 ### 2.1 下載安裝mysql #### 2.1.1 yum安裝mysql ```sh rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm yum -y install yum-utils yum-config-manager --disable mysql80-community yum-config-manager --enable mysql57-community yum install mysql-server -y ``` #### 2.1.2 建立簡單配置檔案 ```sh cat >/etc/my.cnf <<'EOF' [mysqld] character_set_server = utf8mb4 collation_server = utf8mb4_general_ci init_connect = "SET NAMES 'utf8mb4'" [mysql] default-character-set = utf8mb4 EOF ``` #### 2.1.2 啟動mysql並初始設定 ```sh systemctl start mysqld systemctl enable mysqld mysql -u root -p`grep password /var/log/messages|awk '{print $NF}'` # 修改密碼 > set global validate_password_policy=0; > set global validate_password_length=1; > set password=password('123456'); > flush privileges; # 檢查字符集：需要四個都是utf8mb4 > \s ``` ## 3 初始化appllo資料庫 [configdb初始化指令碼](https://github.com/ctripcorp/apollo/blob/1.5.1/scripts/db/migration/configdb/V1.0.0__initialization.sql) [portal初始化指令碼](https://github.com/ctripcorp/apollo/blob/master/scripts/db/migration/portaldb/V1.0.0__initialization.sql) ### 3.1 configdb資料庫 #### 3.1.1下載指令碼並執行： ```sh wget -O apolloconfig.sql https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/db/migration/configdb/V1.0.0__initialization.sql # 匯入sql檔案 mysql -uroot -p123456 < apolloconfig.sql # 檢查是否匯入成功 mysql -uroot -p123456 -e "show databases;"|grep ApolloConfigDB ``` #### 3.1.2 授權並修改初始資料： ```sh mysql -uroot -p123456 > grant INSERT,DELETE,UPDATE,SELECT on ApolloConfigDB.* to 'apollo'@'10.4.7.%' identified by "123456"; # 修改資料 > use ApolloConfigDB > update ServerConfig set Value='http://apollo-config.zq.com/eureka' where Id=1; ``` #### 3.1.3 新增config域名解析： ```sh vi /var/named/zq.com.zone mysql A 10.4.7.11 apollo-config A 10.4.7.10 apollo-admin A 10.4.7.10 apollo-portal A 10.4.7.10 # 重啟並驗證 systemctl restart named dig -t A apollo-config.zq.com @10.4.7.11 +short ``` ### 3.2 portal資料庫 由於portal使用的是另一個portaldb，我們需要在資料庫中新建portdb，並初始化 #### 3.2.1 下載並執行 ```sh wget -O apollo-portal.sql https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/db/migration/portaldb/V1.0.0__initialization.sql # 匯入sql檔案 mysql -uroot -p123456 < apollo-portal.sql # 檢查是否匯入成功 mysql -uroot -p123456 -e "show databases;"|grep ApolloPortalDB ``` #### 3.2.2 授權使用者並更新初始資料 都使用`apollo`使用者來管理資料庫是為了方便,如果有相關的安全考慮可以給config和portal分別使用不同的資料庫賬號 ```sql mysql -uroot -p123456 > grant INSERT,DELETE,UPDATE,SELECT on ApolloPortalDB.* to "apollo"@"10.4.7.%" identified by "123456"; # 更新部門名 > update ApolloPortalDB.ServerConfig set Value='[{"orgId":"zq01","orgName":"研發部"},{"orgId":"zq02","orgName":"運維部"}]' where Id=2; ``` ## 4 部署configservice ### 4.1 製作docker映象 操作在`7.200`上完成 #### 4.1.1 下載程式包 ```sh wget https://github.com/ctripcorp/apollo/releases/download/v1.5.1/apollo-configservice-1.5.1-github.zip mkdir /data/dockerfile/apollo-configservice unzip -o apollo-configservice-1.5.1-github.zip -d /data/dockerfile/apollo-configservice/ ``` #### 4.1.2 修改連線資料庫配置： ```sh cd /data/dockerfile/apollo-configservice/config # 修改資料庫連線地址 sed -i 's#fill-in-the-correct-server#mysql.zq.com#g' application-github.properties # 修改資料庫連線使用者和密碼 sed -i 's#FillInCorrectUser#apollo#g' application-github.properties sed -i 's#FillInCorrectPassword#123456#g' application-github.properties # 檢視結果 config]# egrep -v "^#|$^" application-github.properties spring.datasource.url = jdbc:mysql://mysql.zq.com:3306/ApolloConfigDB?characterEncoding=utf8 spring.datasource.username = apollo spring.datasource.password = 123456 ``` #### 4.1.3 建立啟動指令碼： 程式中自帶的`start.sh`啟動指令碼時不適用與K8S執行,因此需要專門下載他們提供的K8S內使用的指令碼 ```sh # 1.從官網下載啟動指令碼 cd /data/dockerfile/apollo-configservice/scripts/ wget https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/apollo-on-kubernetes/apollo-config-server/scripts/startup-kubernetes.sh # 2. 新增一行使用主機名的變數 sed -i '5i APOLLO_CONFIG_SERVICE_NAME=$(hostname -i)' startup-kubernetes.sh # 3.根據需要修改下jvm限制 ``` #### 4.1.4 編寫dockerfile [ dockerfile官方地址](https://github.com/ctripcorp/apollo/blob/1.5.1/scripts/apollo-on-kubernetes/apollo-config-server/Dockerfile) ```sh cd .. cat >Dockerfile <<'EOF' FROM harbor.zq.com/base/jre8:8u112 ENV VERSION 1.5.1 RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\ echo "Asia/Shanghai" > /etc/timezone ADD apollo-configservice-${VERSION}.jar /apollo-configservice/apollo-configservice.jar ADD config/ /apollo-configservice/config ADD scripts/ /apollo-configservice/scripts CMD ["sh","/apollo-configservice/scripts/startup-kubernetes.sh"] EOF ``` #### 4.1.5 構建docker映象 ```sh docker build . -t harbor.zq.com/infra/apollo-configservice:v1.5.1 docker push harbor.zq.com/infra/apollo-configservice:v1.5.1 ``` ### 4.2 編寫資源配置清單： ```sh mkdir /data/k8s-yaml/apollo-configservice cd /data/k8s-yaml/apollo-configservice ``` #### 4.2.1 建立config的configmap資源清單 給configservice建立cm資源的清單的目的是方便修改 其實裡面的內容就是前面修改的`application-github.properties`檔案 如果確定不會修改,可以不建立此cm,直接寫死配置到docker映象中 ```sh cat >cm.yaml <<'EOF' apiVersion: v1 kind: ConfigMap metadata: name: apollo-configservice-cm namespace: infra data: application-github.properties: | # DataSource spring.datasource.url = jdbc:mysql://mysql.zq.com:3306/ApolloConfigDB?characterEncoding=utf8 spring.datasource.username = apollo spring.datasource.password = 123456 eureka.service.url = http://apollo-config.zq.com/eureka app.properties: | appId=100003171 EOF ``` > 在同一個configmap資源中,可以新增多個配置檔案,上述配置就有兩個,分別是: > `application-github.properties`和`app.properties` #### 4.2.2 建立Deployment資源清單 ```sh cat >dp.yaml <<'EOF' kind: Deployment apiVersion: extensions/v1beta1 metadata: name: apollo-configservice namespace: infra labels: name: apollo-configservice spec: replicas: 1 selector: matchLabels: name: apollo-configservice template: metadata: labels: app: apollo-configservice name: apollo-configservice spec: volumes: - name: configmap-volume configMap: name: apollo-configservice-cm containers: - name: apollo-configservice image: harbor.zq.com/infra/apollo-configservice:v1.5.1 ports: - containerPort: 8080 protocol: TCP volumeMounts: - name: configmap-volume mountPath: /apollo-configservice/config terminationMessagePath: /dev/termination-log terminationMessagePolicy: File imagePullPolicy: IfNotPresent imagePullSecrets: - name: harbor restartPolicy: Always terminationGracePeriodSeconds: 30 securityContext: runAsUser: 0 schedulerName: default-scheduler strategy: type: RollingUpdate rollingUpdate: maxUnavailable: 1 maxSurge: 1 revisionHistoryLimit: 7 progressDeadlineSeconds: 600 EOF ``` #### 4.2.3 建立service資源清單 ```sh cat >svc.yaml <<'EOF' kind: Service apiVersion: v1 metadata: name: apollo-configservice namespace: infra spec: ports: - protocol: TCP port: 8080 targetPort: 8080 selector: app: apollo-configservice EOF ``` #### 4.2.4 建立ingress資源清單 ```sh cat >ingress.yaml <<'EOF' kind: Ingress apiVersion: extensions/v1beta1 metadata: name: apollo-configservice namespace: infra spec: rules: - host: apollo-config.zq.com http: paths: - path: / backend: serviceName: apollo-configservice servicePort: 8080 EOF ``` > service中不一定必須暴露8080,分配的clusterIP中所有的埠都可以 > 但ingress中的servicePort一定要與service中暴露的埠匹配 ### 4.3 應用資源配置清單： #### 4.3.1 任意node執行 ```sh kubectl create -f http://k8s-yaml.zq.com/apollo-configservice/cm.yaml kubectl create -f http://k8s-yaml.zq.com/apollo-configservice/dp.yaml kubectl create -f http://k8s-yaml.zq.com/apollo-configservice/svc.yaml kubectl create -f http://k8s-yaml.zq.com/apollo-configservice/ingress.yaml ``` #### 4.3.2 檢查啟動情況： ```sh kubectl -n infra get pod|grep apollo-config # 檢查命令 kubectl -n infra logs apollo-configservice-64fc749978-9nz5h --tail=4 ```    需要等到eureka啟動以後才可以，接下來使用瀏覽器訪問`apollo-config.zq.com`  ## 5 部署adminservice [官方地址 ](https://github.com/ctripcorp/apollo/releases/download/v1.5.1/apollo-adminservice-1.5.1-github.zip) ### 5.1 製作docker映象 操作在`7.200`上完成 #### 5.1.1 下載程式包 ```sh wget https://github.com/ctripcorp/apollo/releases/download/v1.5.1/apollo-adminservice-1.5.1-github.zip mkdir /data/dockerfile/apollo-adminservice unzip -o apollo-adminservice-1.5.1-github.zip -d /data/dockerfile/apollo-adminservice/ ``` #### 5.1.2 修改連線資料庫配置： 由於使用了configmap資源將配置檔案掛載出來了，所以不在修改配置檔案，如需修改配置檔案，請參考部署apollo-configservice時候的修改方法： #### 5.1.3 建立啟動指令碼： 程式中自帶的`start.sh`啟動指令碼時不適用與K8S執行,因此需要專門下載他們提供的K8S內使用的指令碼 ```sh # 1.從官網下載啟動指令碼 cd /data/dockerfile/apollo-adminservice/scripts/ wget https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/apollo-on-kubernetes/apollo-admin-server/scripts/startup-kubernetes.sh # 2. 新增一行使用主機名的變數 sed -i '5i APOLLO_CONFIG_SERVICE_NAME=$(hostname -i)' startup-kubernetes.sh # 3.修改埠為8080 sed -i 's#8090#8080#g' startup-kubernetes.sh ``` > 官方配置檔案埠改為8090的目的是虛擬機器部署的時候埠不衝突 > 但我們用K8S部署,會給他單獨的clusterIP,所以不用擔心埠重複 #### 5.1.4 編寫dockerfile ```sh cd .. cat >Dockerfile <<'EOF' FROM stanleyws/jre8:8u112 ENV VERSION 1.5.1 RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\ echo "Asia/Shanghai" > /etc/timezone ADD apollo-adminservice-${VERSION}.jar /apollo-adminservice/apollo-adminservice.jar ADD config/ /apollo-adminservice/config ADD scripts/ /apollo-adminservice/scripts CMD ["/bin/bash","/apollo-adminservice/scripts/startup-kubernetes.sh"] EOF ``` > 由於要使用cm配置資源,因此就不改config中的配置了 #### 5.1.5 構建docker映象 ```sh docker build . -t harbor.zq.com/infra/apollo-adminservice:v1.5.1 docker push harbor.zq.com/infra/apollo-adminservice:v1.5.1 ``` ### 5.2 製作資源配置清單： adminservice向註冊中心註冊服務,不直接對外提供服務,因此不需要暴露埠,只需要cm資源和dp資源 ```sh mkdir /data/k8s-yaml/apollo-adminservice cd /data/k8s-yaml/apollo-adminservice ``` #### 5.2.1 建立configmap資源清單 ``` cat >cm.yaml <<'EOF' apiVersion: v1 kind: ConfigMap metadata: name: apollo-adminservice-cm namespace: infra data: application-github.properties: | # DataSource spring.datasource.url = jdbc:mysql://mysql.zq.com:3306/ApolloConfigDB?characterEncoding=utf8 spring.datasource.username = apollo spring.datasource.password = 123456 eureka.service.url = http://apollo-config.zq.com/eureka app.properties: | appId=100003172 EOF ``` > 注意每個服務的appId都不會一樣哦 #### 5.2.2 建立Deployment資源清單 ```sh cat >dp.yaml <<'EOF' kind: Deployment apiVersion: extensions/v1beta1 metadata: name: apollo-adminservice namespace: infra labels: name: apollo-adminservice spec: replicas: 1 selector: matchLabels: name: apollo-adminservice template: metadata: labels: app: apollo-adminservice name: apollo-adminservice spec: volumes: - name: configmap-volume configMap: name: apollo-adminservice-cm containers: - name: apollo-adminservice image: harbor.zq.com/infra/apollo-adminservice:v1.5.1 ports: - containerPort: 8080 protocol: TCP volumeMounts: - name: configmap-volume mountPath: /apollo-adminservice/config terminationMessagePath: /dev/termination-log terminationMessagePolicy: File imagePullPolicy: IfNotPresent imagePullSecrets: - name: harbor restartPolicy: Always terminationGracePeriodSeconds: 30 securityContext: runAsUser: 0 schedulerName: default-scheduler strategy: type: RollingUpdate rollingUpdate: maxUnavailable: 1 maxSurge: 1 revisionHistoryLimit: 7 progressDeadlineSeconds: 600 EOF ``` ### 5.3 應用資源配置清單 #### 5.3.1 任意node執行 ```sh kubectl create -f http://k8s-yaml.zq.com/apollo-adminservice/cm.yaml kubectl create -f http://k8s-yaml.zq.com/apollo-adminservice/dp.yaml ``` #### 5.3.2 檢查啟動情況 ```sh ~]# kubectl -n infra get pod|grep apollo-admin apollo-adminservice-6cd4fcfdc8-2drnq 1/1 Running 0 9s # 檢查命令 kubectl -n infra logs apollo-configservice-6cd4fcfdc8-2drnq --tail=4 ``` 通過 apollo-config.zq.com 檢查是否註冊到了eureka：  已經順利的註冊到了註冊中心中。 ## 6 部署portal ### 6.1 製作docker映象 [portal官方地址](https://github.com/ctripcorp/apollo/releases/download/v1.5.1/apollo-portal-1.5.1-github.zip) #### 6.1.1 下載程式包 ```sh wget https://github.com/ctripcorp/apollo/releases/download/v1.5.1/apollo-portal-1.5.1-github.zip mkdir /data/dockerfile/apollo-portal unzip -o apollo-portal-1.5.1-github.zip -d /data/dockerfile/apollo-portal/ ``` #### 6.1.2 修改配置檔案 由於使用concigmap資源，故不在這裡修改 注意如果要修改的話,要分別修改兩個檔案 1. `apollo-env.properties`修改資料庫配置 2. `apollo-env.properties`修改支援的環境列表 #### 6.1.3 建立啟動指令碼 [指令碼官方地址](https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/apollo-on-kubernetes/apollo-portal-server/scripts/startup-kubernetes.sh) ```sh # 1.從官網下載啟動指令碼 cd /data/dockerfile/apollo-portal/scripts/ wget https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/apollo-on-kubernetes/apollo-portal-server/scripts/startup-kubernetes.sh # 2. 新增一行使用主機名的變數 sed -i '5i APOLLO_CONFIG_SERVICE_NAME=$(hostname -i)' startup-kubernetes.sh # 3.修改埠為8080 sed -i 's#8070#8080#g' startup-kubernetes.sh ``` #### 6.1.4 製作dockerfile： ```sh cd /data/dockerfile/apollo-portal/ cat >Dockerfile <<'EOF' FROM stanleyws/jre8:8u112 ENV VERSION 1.5.1 RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\ echo "Asia/Shanghai" > /etc/timezone ADD apollo-portal-${VERSION}.jar /apollo-portal/apollo-portal.jar ADD config/ /apollo-portal/config ADD scripts/ /apollo-portal/scripts CMD ["/bin/bash","/apollo-portal/scripts/startup-kubernetes.sh"] EOF ``` #### 6.1.5 構建docker映象 ```sh docker build . -t harbor.zq.com/infra/apollo-portal:v1.5.1 docker push harbor.zq.com/infra/apollo-portal:v1.5.1 ``` ### 6.2 編寫資源配置清單： ```sh mkdir /data/k8s-yaml/apollo-portal cd /data/k8s-yaml/apollo-portal ``` #### 6.2.1 建立configmap資源清單 ```sh cat >cm.yaml <<'EOF' apiVersion: v1 kind: ConfigMap metadata: name: apollo-portal-cm namespace: infra data: application-github.properties: | # DataSource spring.datasource.url = jdbc:mysql://mysql.zq.com:3306/ApolloPortalDB?characterEncoding=utf8 spring.datasource.username = apollo spring.datasource.password = 123456 app.properties: | appId=100003173 apollo-env.properties: | dev.meta=http://apollo-config.zq.com EOF ``` > 這裡暫時只管理一個環境,等跑通了以後,再演示多環境問題 #### 6.2.2 建立Deployment資源清單 ```sh cat >dp.yaml <<'EOF' kind: Deployment apiVersion: extensions/v1beta1 metadata: name: apollo-portal namespace: infra labels: name: apollo-portal spec: replicas: 1 selector: matchLabels: name: apollo-portal template: metadata: labels: app: apollo-portal name: apollo-portal spec: volumes: - name: configmap-volume configMap: name: apollo-portal-cm containers: - name: apollo-portal image: harbor.zq.com/infra/apollo-portal:v1.5.1 ports: - containerPort: 8080 protocol: TCP volumeMounts: - name: configmap-volume mountPath: /apollo-portal/config terminationMessagePath: /dev/termination-log terminationMessagePolicy: File imagePullPolicy: IfNotPresent imagePullSecrets: - name: harbor restartPolicy: Always terminationGracePeriodSeconds: 30 securityContext: runAsUser: 0 schedulerName: default-scheduler strategy: type: RollingUpdate rollingUpdate: maxUnavailable: 1 maxSurge: 1 revisionHistoryLimit: 7 progressDeadlineSeconds: 600 EOF ``` #### 6.2.3 建立service資源清單 ```sh cat >svc.yaml <<'EOF' kind: Service apiVersion: v1 metadata: name: apollo-portal namespace: infra spec: ports: - protocol: TCP port: 8080 targetPort: 8080 selector: app: apollo-portal EOF ``` #### 6.2.4 建立ingress資源清單 ```sh cat >ingress.yaml <<'EOF' kind: Ingress apiVersion: extensions/v1beta1 metadata: name: apollo-portal namespace: infra spec: rules: - host: apollo-portal.zq.com http: paths: - path: / backend: serviceName: apollo-portal servicePort: 8080 EOF ``` ### 6.3 應用資源配置清單 #### 6.3.1 在任意node執行 ```sh kubectl create -f http://k8s-yaml.zq.com/apollo-portal/cm.yaml kubectl create -f http://k8s-yaml.zq.com/apollo-portal/dp.yaml kubectl create -f http://k8s-yaml.zq.com/apollo-portal/svc.yaml kubectl create -f http://k8s-yaml.zq.com/apollo-portal/ingress.yaml ``` #### 6.3.2 檢查啟動情況  #### 6.3.3 網頁驗證 由於前面已經一起添加了域名解析,因此portal建立好後不需要在新增域名解析,直接瀏覽器登入驗證 網頁：apollo-portal.zq.com 預設使用者名稱：apollo 預設密碼：admin 登入成功後,立馬修改密碼為`apollo123` 到此，apollo的三個元件都已經交付到k8s裡了。 ## 7 配置服務使用apollo配置中心 使用配置中心，需要開發對程式碼進行調整，將一些配置，通過變數的形式配置到apollo中，服務通過配置中心來獲取具體的配置 ### 7.1 新建dubbo-service專案配置 #### 7.1.1 在配置中心修改新增專案: **專案屬性：** AppId：dubbo-demo-service 應用名稱：dubbo服務提供者 部門：研發部 **為新專案新增配置如下：** | key | value | 備註 | | -------------- | --------------------------- | ----------------- | | dubbo.registry | zookeeper://zk1.zq.com:2181 | 註冊中心地址 | | dubbo.port | 20880 | dubbo服務監聽埠 | **釋出後效果圖如下：**  #### 7.1.2 重新打包service映象 還是使用之前的流水線，但是使用分支為apollo的程式碼進行打包，引數如下： | 引數名 | 引數值 | | ---------- | ------------------------------------------------- | | app_name | dubbo-demo-service | | image_name | app/dubbo-demo-service | | git_repo | https://gitee.com/noah-luo/dubbo-demo-service.git | | git_ver | apollo | | add_tag | 200512_0746 | | mvn_dir | ./ | | target_dir | ./dubbo-server/target | | mvn_cmd | mvn clean package -Dmaven.test.skip=true | | base_image | base/jre8:8u112 | | maven | 3.6.1 | #### 7.1.3 重新應用資源配置清單 修改dp.yaml資源配置清單 1. 將映象改為剛剛打包的映象名： 2. 新增環境變數`C_OPTS`,以便指定配置中心 ```sh vim /data/k8s-yaml/dubbo-server/dp.yaml #----------原內容---------- spec: containers: - name: dubbo-demo-service image: harbor.zq.com/app/dubbo-demo-service:master_200509_0800 ports: - containerPort: 20880 protocol: TCP env: - name: JAR_BALL value: dubbo-server.jar #----------新內容---------- spec: containers: - name: dubbo-demo-service image: harbor.zq.com/app/dubbo-demo-service:apollo_200512_0746 ports: - containerPort: 20880 protocol: TCP env: - name: JAR_BALL value: dubbo-server.jar - name: C_OPTS value: -Denv=dev -Dapollo.meta=http://apollo-config.zq.com ``` **應用資源配置清單：** ```sh kubectl apply -f http://k8s-yaml.zq.com/dubbo-server/dp.yaml ``` ### 7.2 新建dubbo-web專案配置 #### 7.2.1 在配置中心修改新增專案: **專案屬性：** AppId：dubbo-demo-web 應用名稱：dubbo服務消費者 部門：運維部 **為新專案新增配置如下：** | key | value | 備註 | | -------------- | --------------------------- | ------------ | | dubbo.registry | zookeeper://zk1.zq.com:2181 | 註冊中心地址 | **釋出後效果圖如下：** 略 #### 7.1.2 重新打包service映象 還是使用之前的流水線，但是使用分支為apollo的程式碼進行打包，引數如下： | 引數名 | 引數值 | | ---------- | ----------------------------------------- | | app_name | dubbo-demo-consumer | | image_name | app/dubbo-demo-consumer | | git_repo | [email protected]:noah-luo/dubbo-demo-web.git | | git_ver | apollo | | add_tag | 200512_0801 | | mvn_dir | ./ | | target_dir | ./dubbo-client/target | | mvn_cmd | mvn clean package -Dmaven.test.skip=true | | base_image | base/jre8:8u112 | | maven | 3.6.1 | 構建完成後，修改資源配置清單並應用： #### 7.1.3 重新應用資源配置清單 修改dp.yaml資源配置清單 1. 將映象改為剛剛打包的映象名： 2. 新增環境變數`C_OPTS`,以便指定配置中心 ```sh vim /data/k8s-yaml/dubbo-consumer/dp.yaml #----------原內容---------- spec: containers: - name: dubbo-demo-consumer image: harbor.zq.com/app/dubbo-demo-consumer:master_200506_1430 ports: - containerPort: 8080 protocol: TCP - containerPort: 20880 protocol: TCP env: - name: JAR_BALL value: dubbo-client.jar #----------新內容---------- spec: containers: - name: dubbo-demo-consumer image: harbor.zq.com/app/dubbo-demo-consumer:apollo_200512_0801 ports: - containerPort: 8080 protocol: TCP - containerPort: 20880 protocol: TCP env: - name: JAR_BALL value: dubbo-client.jar - name: C_OPTS value: -Denv=dev -Dapollo.meta=http://apollo-config.zq.com ``` **應用資源配置清單：** ```sh kubectl apply -f http://k8s-yaml.zq.com/dubbo-consumer/dp.yaml ``` ### 7.3 驗證結果 #### 7.3.1 修改dubbo-monitor資源 管理機上,修改dubbo-monitor的dp資源的使用的cm資源 ```sh set -i 's#dubbo-monitor-cm-pro#dubbo-monitor-cm#g' /data/k8s-yaml/dubbo-monitor/dp-cm.yaml ``` **任意node節點應用資源** ```sh kubectl apply -f http://k8s-yaml.zq.com/dubbo-monitor/dp.yaml ``` **登入dubbo-monitor檢視** 訪問http://dubbo-monitor.zq.com/  **瀏覽器檢視** 訪問http://dubbo-demo.zq.com/hello?name=lg  **apollo中看例項列表** ![img](https://img2018.cnblogs.com/i-beta/1034759/201912/1034759-20191212172635322-132994833.pn
