安装docker

Homebrew 的 Cask 已经支持 Docker for Mac，因此可以很方便的使用 Homebrew Cask 来进行安装

brew cask install docker

移除旧的版本

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine

安装一些必要的系统工具

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

添加软件源

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

更新 yum 缓存

sudo yum makecache fast

安装 Docker-ce

sudo yum -y install docker-ce

启动 Docker 后台服务

sudo systemctl start docker

测试运行 hello-world

docker run hello-world

使用Maven对项目进行编译

mvn clean install docker:build

使用docker直接运行项目

docker run -it -p 8080:9080 guoxin/docker-demo

安装Jenkins并使用自动化部署该项目

使用docker同步jenkins镜像

docker pull jenkins/jenkins:lts

运行jenkins的镜像的时候有两种映射本地磁盘的方式

创建jenkins目录

mkdir ~/jenkins_home

给目录的归属者赋给UID1000，这里有一个权限的问题 详情请看这里

chown -R 1000:1000 ~/jenkins_home

docker run -d -v ~/jenkins_home:/var/jenkins_home -p 8080:8080 -p 50000:50000 jenkins/jenkins:lts

cat ~/jenkins_home/_data/secrets/initialAdminPassword

e9ce325859834111943e766fe07c9e55

docker run -d -v jenkins_home:/var/jenkins_home -p 8080:8080 -p 50000:50000 jenkins/jenkins:lts

docker volume inspect jenkins_home

[
{
"CreatedAt": "2018-11-17T16:50:02+08:00",
"Driver": "local",
"Labels": null,
"Mountpoint": "/var/lib/docker/volumes/jenkins_home/_data",
"Name": "jenkins_home",
"Options": null,
"Scope": "local"
}
]

我们可以通过Mountpoint属性的路径进入到Volume所映射的路径，可以查看相关文件（但是不推荐在宿主机中直接修改文件推荐直接进入到容器中进行修改操作）

cat /var/lib/docker/volumes/jenkins_home/_data/secrets/initialAdminPassword

e9ce325859834111943e766fe07c9e55

这两种方法都可以实现把容器里的数据持久化到本地，但是更推荐第二种方法

<authorizationStrategy class="hudson.security.AuthorizationStrategy$Unsecured"/>
  <securityRealm class="hudson.security.SecurityRealm$None"/>

将密码填写到jenkins的页面中就可以了

sudo docker run -t -i -p 8080:8080 -v /etc/localtime:/etc/localtime:ro -v jenkins_home:/var/jenkins_home -P stephenreed/java8-jenkins-maven-git-nano
