先编译生成jar包
mvn clean   install -Dmaven.test.skip
再打镜像
docker build -t dyyx/hello:v1 .

springboot-docker-demo/Dockerfile

FROM java:8
# FROM openjdk:8u312-slim
ARG JAR_FILE=target/springboot-docker-demo-1.0.jar
ADD ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]



ENTRYPOINT 两种写法
exec写法 JSON风格
ENTRYPOINT ["java","${JAVA_OPTS}","-jar","/app.jar"]

shell写法
ENTRYPOINT java ${JAVA_OPTS} -jar /app.jar
