Docker新手攻略：编辑Dockerfile、构建镜像、启动容器全攻略

万能dockerfile编写模板文件

FROM openjdk:11.0 as builder
WORKDIR application
ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} application.jar
RUN java -Djarmode=layertools -jar application.jar extract

FROM openjdk:11.0
WORKDIR application
COPY --from=builder application/dependencies/ ./
COPY --from=builder application/spring-boot-loader/ ./
COPY --from=builder application/snapshot-dependencies/ ./
COPY --from=builder application/application/ ./
ENTRYPOINT ["java", "org.springframework.boot.loader.JarLauncher"]

文件上传到服务器（关键是在于路径）

构建build镜像

docker build . --tag java-project-name

java-project-name 构建的镜像名称

例如

docker build . --tag layered-jars

启动或者运行容器

docker run -d -it -p 8080:8080 java-project-name:latest

例如

docker run -it -d -p 15000:15000 rsc-chat-ai:latest

查端口进程

netstat -lnp|grep 15000

（大功告成）容器运行成功 请求吧！
