dockerfile

# 使用官方的 OpenJDK 作为基础镜像
FROM openjdk:latest

# 设置工作目录
WORKDIR /app

# 将本地的 JAR 文件复制到容器内
COPY ./target/your-application.jar /app/your-application.jar

# 指定容器启动时要执行的命令
CMD ["java", "-jar", "your-application.jar"]

一键启动部署

#!/bin/bash

echo "检查更新"
git pull
# 项目清理
mvn clean
echo "清理上次打包文件..."
echo "开始重新项目打包..."
mvn package
echo "项目打包完成！"

# 定义容器名称和镜像名称【都小写】
container_name="your-container-name"
image_name="your-image-name"

# 检查容器是否已经在运行
if docker ps -a --format '{{.Names}}' | grep -q "^${container_name}$"; then
    echo "Container $container_name already exists. Removing..."
    # 停止并删除现有的容器
    docker stop $container_name && docker rm $container_name
fi

# 检查镜像是否存在
if docker images --format '{{.Repository}}' | grep -q "^${image_name}$"; then
    echo "Image $image_name already exists. Removing..."
    # 删除现有的镜像
    docker rmi $image_name
fi

# 构建镜像
echo "Building image $image_name..."
docker build -t $image_name .

# 启动容器
echo "Starting container $container_name..."
docker run -d -p 8082:8080 --name $container_name $image_name

echo "Container $container_name started successfully."

番外：本地idea远程发布

DANGER

很慢，不推荐
