Docker实战笔记二 Springboot Idea 插件打包

1.上传springboot的jar

root@cenots-7.5:/home/code#rz  -----app.jar

2.编辑Dockerfile

root@cenots-7.5:/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/timezoneEXPOSE 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

root@cenots-7.5:/home/code#docker build -t hello:1.0 .
[+] Building 1.5s (9/9) FINISHED                                                                  => [internal] load build definition from Dockerfile                                         0.0s=> => transferring dockerfile: 578B                                                         0.0s=> [internal] load .dockerignore                                                            0.0s=> => transferring context: 2B                                                              0.0s=> [internal] load metadata for docker.io/library/openjdk:8                                 0.9s=> CACHED [1/4] FROM docker.io/library/openjdk:8@sha256:86e863cc57215cfb181bd319736d0baf62  0.0s=> [internal] load build context                                                            0.1s=> => transferring context: 19.18MB                                                         0.1s=> [2/4] ADD /app.jar /app.jar                                                              0.1s=> [3/4] ADD /application.yml /application.yml                                              0.0s=> [4/4] RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >  0.3s=> exporting to image                                                                       0.1s=> => exporting layers                                                                      0.1s=> => writing image sha256:9f826b92d5b2142b92a6977f4728ea4cc93a6a2847a7314c07f92b5ae9fb932  0.0s=> => naming to docker.io/library/hello:1.0

4.查看并启动容器

 root@cenots-7.5:/home/code#docker images
REPOSITORY             TAG                IMAGE ID       CREATED         SIZE

seataio/seata-server   1.4.2              4909c4c024dc   2 years ago     156MB

5.启动容器

root@cenots-7.5:/home/code#docker run -d --name h1 -p 9666:9933 hello:1.0
33ef6638f3dddcbfbce243140ada085148bc127f783fb8d7f10c9a4ca1245265
root@cenots-7.5:/home/code#docker ps

6.调用服务接口http://ip:9666/login 查看日志

已打印登录信息，启动成功完成。

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.serviceExecStart=/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
