使用脚本把springboot程序部署到k8s上
一般我们部署写4个文件就行了
首先分别写
- Dockerfile
- 1package.sh
- 2build.sh
- docker_push.sh
Dockerfile
# 基于jdk1.8
FROM openjdk:8-jdk-alpine
RUN echo "Asia/Shanghai" > /etc/timezone
RUN mkdir /app
WORKDIR /appCOPY ./monitor-flink-1.0.jar /appEXPOSE 8080CMD ["java","-jar","/app/monitor-flink-1.0.jar"]
springboot打包
<build><finalName>monitor-flink-1.0</finalName><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.8.1</version><configuration><source>1.8</source><target>1.8</target><encoding>UTF-8</encoding></configuration></plugin><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>2.5.14</version><configuration><mainClass>com.donglin.MonitorApplication</mainClass><!-- <skip>true</skip>--></configuration><executions><execution><id>repackage</id><goals><goal>repackage</goal></goals></execution></executions></plugin></plugins><resources><resource><directory>src/main/resources</directory><filtering>true</filtering></resource></resources></build>1package.sh
从github上拉下来,打成jar包
#!/bin/bash
export JAVA_HOME=/data/xxx/jdk/jdk1.8.0_141
export PATH=${JAVA_HOME}:$PATH
cd /data/flink-monitor
rm -rf /data/flink-monitor/monitor-flinkexport http_proxy=http://xxx.xxx.xxx.xxx:3128
export https_proxy=https://xxx.xxx.xxx.xxx:3128
git clone https://GitHub上生成的ssh密钥@github.com/lidonglin/flink-monitor.gitcd /data/flink-monitor/monitor-flink
git checkout mainsh /data/xxx/maven/maven-3.6.3/bin/mvn clean
sh /data/xxx/maven/maven-3.6.3/bin/mvn -P dev -Dmaven.test.skip=true packagemv /data/flink-monitor/monitor-flink/target/monitor-flink-1.0.jar /data/flink-monitor/monitor-flink-1.0.jar
2build.sh
#!/bin/bash
sudo docker build -t flink-monitor:latest
docker_push.sh
将docker镜像推送到k8s
#!/bin/bash
VERSION=latestsudo docker login xxxxxx.com --username xxxxxx --password xxxxxx
sudo docker tag flink-monitor:$VERSION xxxx/xxxx/flink-monitor:$VERSION
sudo docker push xxxx/xxx/flink-monitor:$VERSIONexport https_proxy=
export http_proxy=
kubectl rollout restart deployment flink-monitor --namespace=app
tips
# 把旧镜像的名字，改成仓库要求的新版名字
docker tag donglin:v1.0 donglin/nginx:v1.0
最后生成的文件
