docker 部署 springboot项目和直接运行 jar 文件详细步骤

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

	146bd6a88618: Downloading [==============>                                    ]  9.682MB/33.72MB

	e7873a7ca0fd: Pull complete

	Digest: sha256:de5312e3f2abecaafa3a58ae1752595880366ac616847bd23ee8cb2fb984b7be

	Status: Downloaded newer image for openjdk:8

	docker.io/library/openjdk:8

	[root@dex backstage_proj]# docker images

	REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

	openjdk             8                   f8146facf376        9 days ago          488MB

	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 .

	Sending build context to Docker daemon  69.68MB

	Step 1/7 : FROM docker.io/openjdk:8

	 ---> f8146facf376

	[root@dex leshan]# docker images

	node                latest              2af77b226ea7        4 weeks ago         934MB

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

	2020-01-06T13:42:56.203072863Z

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

	[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

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tag
java -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
