Centos7学习docker

1.yum install docker

centos以上直接下载docker.

2.下载jenkins包，创建启动jenkins容器，下载jenkins插件

docker run -d --name jenkins -p 49001:8080 -v /home/jenkins_home:/home/jenkins_home jenkins/jenkins:lts

49001端口映射容器的8080端口，首次进入需要password，进入容器 docker exec -it containerId /bin/bash

3.部署spring boot项目 

修改pom文件

添加DockerFile

FROM openjdk:8-jdk-alpine

VOLUME /tmp

ADD spring-boot-docker-1.0.jar app.jar

ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
