安装

此处直接安装最新，或者指定版本安装

yum install docker-ce  #默认最新
yum install docker-ce-19.03.3-3.el7 #安装指定版本

启动

systemctl start docker

查看运行状态

systemctl status docker

部署应用程序

Springboot配置

编写Dockerfile

FROM java:8
VOLUME /tmp
ADD csdnranks-1.0.jar csdnranks.jar
EXPOSE 18200
ENTRYPOINT ["java","-jar","/csdnranks.jar"]

配置pom文件

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            

            
                com.spotify
                docker-maven-plugin
                1.2.1
                
                    ${docker.image.prefix}/${project.artifactId}
                    src/main/docker
                    
                        
                            /
                            ${project.build.directory}
                            ${project.build.finalName}.jar
                        
                    
                
            
        
    

服务器配置

jar配置

把编译好的jar包和dockerfile放在服务器的同一个目录下，如/home/files/

创建镜像

在目录种执行命令创建镜像

docker build -t csdn:1.0 .   #这个.代表当前目录,不能忽略

运行容器

把创建的镜像实例化到容器中，运行起来

可以配置不同的option，此处使用简单的命令

# -d 后台运行 
#csdn:1.0运行指定镜像名字和版本
#-p 8889主机端口号  映射 18200容器内应用端口号
#--name给运行的容器起个名字
#等等
docker run -d csdn:1.0 -p 8889:18200 --name=wdnmd

查看容器内应用日志

真正应用中可以通过docker安装elk组件进行微服务日志收集，此处是最简单查看容器的日志

[root@jiba01 files]# docker logs wdnmd
