+# 制作Springboot镜像
+
+## 系统打包
+
+### 编写Dockerfile
+
+```dockerfile
+FROM openjdk:8u292-jre-buster
+ARG JAR_FILE=*.jar
+COPY ${JAR_FILE} gateway.jar
+ENTRYPOINT ["java","-jar","-Dspring.profiles.active=prod","/gateway.jar"]
+```
+
+### 打包
+
+```bash
+$ docker build -t gateway-docker .
+```
+
+### 后台运行
+
+```bash
+$ docker run --name Gateway -p 9099:9999 --network service --network-alias gateway -d gateway-docker
+```
+
+注意：打包时jar包与dockerfile在同一目录下
