Docker部署SpringBoot

方式1（Dockerfile + JAR本地构建）

• Dockerfile文件【src/main/docker/Dockerfile】

# Docker image for springboot file run
# 基础java镜像，需要提前安装：docker pull java:8
FROM java:8

# 解决中文乱码
ENV LANG C.UTF-8:
# 设置alpine时区
ENV TIMEZONE Asia/Shanghai
# 在主机 /var/lib/docker 目录下创建了一个临时文件，并链接到容器的/tmp
VOLUME /tmp
# 将Demo1-20211208.jar包添加到容器中并更名为Demo1.jar
ADD Demo1-20211208.jar Demo1.jar
# 暴露容器运行时的 8088 监听端口给外部
EXPOSE 8088/tcp
# 启动容器时执行的 Shell 命令
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/Demo1.jar"]

• 制作镜像

# 将/target/Demo1文件夹移动到指定目录下进行部署，详细构建参数：https://www.runoob.com/docker/docker-build-command.html
cd ../Demo1 && docker build -t 镜像名称(小写):标签名称 .
# 查看docker镜像
docker images

• 启动容器

# 启动容器
docker run -itd --name demo1[容器名称] -p 8088:8088 demo1[镜像名称]
# 查询日志
docker logs 容器id
