目前docker发布springboot有两种方式，一种是制作镜像，另一种是直接运行jar 文件
第一种使用镜像来部署
一、创建项目目录
[root@dex ~]# mkdir /opt/backstage_proj/leshan
二、安装jdk
这里直接使用docker pull一个openjdk镜像下来就ok了（比宿主机安装省事）
[root@dex backstage_proj]# docker pull docker.io/openjdk:8
8: Pulling from library/openjdk
146bd6a88618: Downloading [=============> ] 9.337MB/33.72MB

docker.io/library/openjdk:8
[root@dex backstage_proj]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

vuedev v1 1e9d51839b07 10 days ago 1.14GB
node latest 2af77b226ea7 4 weeks ago 934MB
[root@dex backstage_proj]#
三、配置Dockerfile
[root@dex ~]# cd /opt/backstage_proj/leshan
[root@dex leshan]# vi Dockerfile
FROM docker.io/openjdk:8
# author
MAINTAINER dex
# 将容器挂载如下目录
VOLUME /opt/backstage_proj/tmp
#将jar 添加进来
ADD lszz-0.0.1-SNAPSHOT.jar leshan_bk.jar
# 时区
RUN echo "Asia/Shanghai" > /etc/localtime_bak
EXPOSE 8301
ENTRYPOINT ["java","-jar","/leshan_bk.jar"]
~
~
~
~
~
~
:wq
现在再次查看该目录下应该有如下两个文件
[root@dex ~]# ll /opt/backstage_proj/leshan/
total 68056
-rw-r--r-- 1 root root 291 Jan 6 21:39 Dockerfile
-rw-r--r-- 1 root root 69681782 Jan 6 16:51 lszz-0.0.1-SNAPSHOT.jar
[root@dex ~]#
四、制作镜像
[root@dex leshan]# docker build -t leshan_bk .

五、 运行容器
[root@dex leshan]# docker run -p 8301:8201 --name ls_bk -d leshan_bk
30bbc32a1e956d51e7d8f589611bb46b2ba85924435b79a22d9a0972f4fc5cb8
六、查看运行的容器
[root@dex backstage_proj]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
30bbc32a1e95 leshan_bk "java -jar /leshan_b…" 2 minutes ago Up 2 minutes 8301/tcp, 0.0.0.0:8301->8201/tcp ls_bk
1719b24f00a7 vuedev:v1
七、查看日志
[root@dex leshan]# docker logs -f -t --tail 200 ls_bk

八、nginx配置反向代理
location /lsBk/ {
proxy_pass http://127.0.0.1:8301/;
}
页面就可以使用 域名+ /lsBk/ + 接口 进行访问了
第二种直接运行 jar文件
一、docker直接运行jar
有的时候将springboot 打包镜像然后运行容器比较麻烦，这个较适用于项目上线发布，在平时测试还是使用docker 直接运行jar 较方便
- 1、先停掉刚才的docker 容器
[root@dex nginx]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
30bbc32a1e95 leshan_bk "java -jar /leshan_b…" 30 minutes ago Up 30 minutes 8301/tcp, 0.0.0.0:8301->8201/tcp ls_bk
1719b24f00a7 vuedev:v1 "docker-entrypoint.s…" 11 days ago Up 11 days 9009/tcp, 0.0.0.0:8191->8009/tcp vuedev2
[root@dex nginx]# docker stop 30b
30b
[root@dex nginx]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1719b24f00a7 vuedev:v1 "docker-entrypoint.s…" 11 days ago Up 11 days 9009/tcp, 0.0.0.0:8191->8009/tcp vuedev2
[root@dex nginx]#
- 2、执行run命令
[root@dex nginx]# docker run -p 8301:8201 -v /opt/backstage_proj/leshan/lszz-0.0.1-SNAPSHOT.jar:/opt/backsttage_proj/tmp02/lszz-0.0.1-SNAPSHOT.jar --name ls_bk02 docker.io/openjdk:8 java -jar /opt/backstage_proj/tmp02/lszz-0.0.1-SNAPSHOT.jar

看这个和上面第七步是不是一模一样呢。
二、容器查看
[root@dex leshan]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
736586c25763 openjdk:8 "java -jar /opt/back…" 2 minutes ago Up 2 minutes 0.0.0.0:8301->8201/tcp ls_bk02
30bbc32a1e95 leshan_bk "java -jar /leshan_b…" 39 minutes ago Exited (143) 8 minutes ago ls_bk
1719b24f00a7 vuedev:v1 "docker-entrypoint.s…" 11 days ago Up 11 days 9009/tcp, 0.0.0.0:8191->8009/tcp vuedev2
[root@dex leshan]#
使用 docker ps -a查看所有容器 ；发现刚才使用docker 直接运行jar 其实也是创建了一个容器ls_bk02
三、 配置说明
-d 表示在后台启动
-p 8301:8201 表示将容器的8201端口 映射到宿主主机的8301端口，否则外部8301端口访问不到
-v /opt/backstage_proj/leshan/lszz-0.0.1-SNAPSHOT.jar:/opt/backsttage_proj/tmp02/lszz-0.0.1-SNAPSHOT.jar 表示将宿主主机的jar文件，挂载到容器中（分号前为宿主主机的路径，分号后为容器中的路径） --name ls_bk02 表示为该容器取一个全局唯一的名称（这个随意） docker.io/openjdk:8 表示运行jar 所选的镜像文件的名称和tagjava -jar /usr/springboot-1.jar 表示运行jar包，注意：这里的jar包为容器中的位置，是通过前面的-v属性映射的
