在ARM64的架构服务器上进行Docker的jar包镜像部署

本机是WIndows，AMD64架构的；目标Linux服务器是ARM64架构的Debian。进行jar包的容器部署方式。

目标服务器

root@localhost:~# uname -a
Linux localhost 5.10.0-11-arm64 #1 SMP Debian 5.10.92-2 (2022-02-28) aarch64 GNU/Linux
root@localhost:~# arch
aarch64

第1次尝试

Dockerfile

# 基础镜像
FROM openjdk:8-jdk-alpine

# 拷贝jar包
COPY ./target/arm64web-0.0.1-SNAPSHOT.jar /opt/arm64web-0.0.1-SNAPSHOT.jar

# 端口和工程启动的端口一致
EXPOSE 8080

# 运行命令
ENTRYPOINT ["java", "-jar", "-Duser.timezone=Asia/Shanghai", "/opt/arm64web-0.0.1-SNAPSHOT.jar"]

打包命令

# 打包命令
docker build -t arm64web:1.0 .

# 容器输出命令
docker save -o arm64web.tar arm64web:1.0

运行出错

root@localhost:~# docker images
REPOSITORY   TAG       IMAGE ID       CREATED          SIZE
arm64web     1.0       74d619bb615d   11 minutes ago   122MB
root@localhost:~# docker run -p 8080:8080 --name arm64web arm64web:1.0
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

第2次尝试

修改打包命令

docker buildx build --platform linux/arm64 -t arm64web:2.0 .

则运行成功

root@iZbp14skqirpwqnij2h78cZ:~# docker run -p 8080:8080 --name arm64web arm64web:2.0
