JDK17 + Springboot3 + CentOS7.5 的Docker安装及部署

彻底卸载

sudo yum remove -y docker-ce docker-ce-cli containerd.io
sudo rm -rf /var/lib/docker /etc/docker

安装依赖

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

添加阿里云镜像源

sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo sed -i ‘s/download.docker.com/mirrors.aliyun.com/docker-ce/g’ /etc/yum.repos.d/docker-ce.repo

安装 Docker CE

sudo yum install -y docker-ce docker-ce-cli containerd.io

启动并设置开机自启

sudo systemctl start docker
sudo systemctl enable docker

验证安装

docker version

在你本地编译并产生 JDK17+Springboot web 的Jar包

cd D:\workspace_java\jdk17Test\jdk17Test
mvn clean package -DskipTests

服务器上 - put the compiled file

服务器目录结构

/app/jdk17ApplicationJar
|-Dockerfile
|-jdk17Test-1.0-SNAPSHOT.jar

mkdir /app/jdk17Application
sftp root@192.168.98.157
put /d/workspace_java/jdk17Test/jdk17Test/target/jdk17Test-1.0-SNAPSHOT.jar /app/jdk17Application/

创建或修改配置文件

详见https://cloud.tencent.com/developer/article/25294185

sudo tee /etc/docker/daemon.json <<-‘EOF’
{
“registry-mirrors”: [
“https://docker-0.unsee.tech”,
“https://docker-cf.registry.cyou”,
“https://docker.1panel.live”
]
}
EOF

重启Docker生效

sudo systemctl daemon-reload
sudo systemctl restart docker

#编辑Dockerfile
FROM openjdk:17-jdk
VOLUME /tmp
COPY jdk17Test-1.0-SNAPSHOT.jar app.jar
EXPOSE 8080
ENTRYPOINT [“java”, “-Djava.security.egd=file:/dev/./urandom”, “-jar”, “/app.jar”]

#编译，生成镜像，这个时候/etc/docker/daemon.json是否有效就很重要
docker build -t springboot-jdk17-app .

#创建网络
docker network create --driver bridge springboot-net

#启动镜像
docker run -d
–name springboot-container
–network springboot-net
-p 8081:8081
springboot-jdk17-app

#获取容器 IP
docker inspect -f ‘{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}’ springboot-container
#检查端口映射
docker port springboot-container 8081
#确认服务启动
docker logs -f springboot-container
