k8s配置中心實戰-交付apollo三元件

目錄

1 apollo簡單說明

官方地址
概念請參考:

1.1 apollo最簡架構圖:

img

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

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

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

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
portal初始化指令碼

3.1 configdb資料庫

3.1.1下載指令碼並執行:

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:

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:

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

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

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

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:

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

# 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

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

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:

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

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.propertiesapp.properties

4.2.2 建立Deployment資源清單

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

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

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

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:

kubectl -n infra get pod|grep apollo-config

# 檢查命令
kubectl -n infra logs apollo-configservice-64fc749978-9nz5h --tail=4

5 部署adminservice

官方地址

5.1 製作docker映象

操作在7.200上完成

5.1.1 下載程式包

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

# 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

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

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

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

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

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

~]# 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:
mark

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

6.1.1 下載程式包

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

# 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:

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

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:

mkdir /data/k8s-yaml/apollo-portal
cd /data/k8s-yaml/apollo-portal

6.2.1 建立configmap資源清單

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

cat >dp.yaml <<'EOF'
kind: Deployment
apiVersion: extensions/v1beta1
metadata:

    rollingUpdate: 
      maxUnavailable: 1
      maxSurge: 1
  revisionHistoryLimit: 7
  progressDeadlineSeconds: 600
EOF

6.2.3 建立service資源清單

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

        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

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

由於前面已經一起新增了域名解析,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:
mark

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
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:

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:

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 git@gitee.com: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
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

          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

        - name: C_OPTS
          value: -Denv=dev -Dapollo.meta=http://apollo-config.zq.com

應用資源配置清單:

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

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

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/
