Docker实战笔记 二 Springboot Idea 插件打包
1.上传springboot的jar
[email protected]:/home/code#rz -----app.jar2.编辑Dockerfile
[email protected]:/home/code#vi Dockerfile
内容
FROM openjdk:8
# 作者
MAINTAINER nnd
# 声明要使用的端口
EXPOSE 8080
# VOLUME 指定了临时文件目录为/tmp。
# 将本地包添加到容器中并更名为容器内目录名
ADD /app.jar /app.jar
ADD /application.yml /application.yml
#挂载卷
# 同步容器与本机时间
RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo 'Asia/Shanghai' >/etc/timezone
EXPOSE 9933
#ENTRYPOINT命令用于指定这个容器启动的时候要运行的命令(可以追加命令)
ENTRYPOINT ["java","-jar","app.jar"]
3.制作Docker镜像
[email protected]:/home/code#docker build -t hello:1.0 .

=> => naming to docker.io/library/hello:1.0 4.查看并启动容器

IDEA插件方式
首先把docker服务的远程端口打开
[root@localhost ~]# vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd-current -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375 \
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker
