平时经常用Docker来部署各种环境，发现从DockerHub上下载镜像有时候比较慢。第三方的镜像还可以使用一些国内的镜像仓库来加速，如果我们自己构建的镜像那就不行了。这时候搭建一个私有的镜像仓库很有必要，最近发现Harbor这个企业级镜像仓库，非常好用且功能强大，推荐给大家！

Harbor简介
Harbor是一款开源的Docker镜像仓库服务，在Github上目前有13.4k+Star。提供了基于角色的镜像访问机制，可以保护你的镜像安全。
安装
学习开源项目的第一步，一般都是把它运行起来，我们先来把Harbor运行起来吧！
- 下载Harbor安装包，这里下载的是
v1.10.6离线版本，下载地址：https://github.com/goharbor/h...
- 下载完成后上传到Linux服务器，使用如下命令解压；
tar xvf harbor-offline-installer-v1.10.6.tgz- 解压完成后，所有文件内容如下；
[root@linux-local harbor]# ll
total 700260
drwxr-xr-x. 3 root root 20 Dec 2 11:18 common
-rw-r--r--. 1 root root 3398 Nov 17 11:58 common.sh

no_proxy:
components:
- core
- jobservice
- clair- 使用
install.sh脚本安装Harbor:
./install.sh- Harbor启动成功后会输出如下信息，这里需要注意的是Harbor会启动Nginx、Redis之类的容器，以前创建过的需要先删除掉，看到
started successfully就表示启动成功了；

admin:Harbor12345登录即可，访问地址：http://192.168.3.101/
使用
接下来我们就可以使用Harbor来管理我们的镜像了。
- 首先点击
新建项目按钮，新建一个项目：
- 这里新建一个叫做
test的私有项目；
- 由于
docker login命令默认不支持http访问，所以我们需要手动开启，使用Vim编辑器修改docker的配置文件daemon.json；
vi /etc/docker/daemon.json- 添加一行
insecure-registries配置即可，允许使用非安全方式访问Harbor镜像仓库，注意不要少了端口号80；
{
"registry-mirrors":["https://xxx.aliyuncs.com"],
"insecure-registries":["192.168.3.101:80"]
}- 再次重新启动docker服务；
systemctl restart docker- 再次使用
install.sh启动Harbor服务；
./install.sh- 使用
docker login命令访问Harbor镜像仓库，注意加上端口号为80；
[root@linux-local harbor]# docker login 192.168.3.101:80
Username: admin
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded- 编写Dockerfile脚本，用于构建Docker镜像，一个最简单的busybox脚本如下；
FROM busybox:latest- 使用如下命令构建一个自己的busybox镜像；
docker build -t 192.168.3.101:80/test/busybox .- 将自己构建的busybox镜像推送到Harbor镜像仓库；
docker push 192.168.3.101:80/test/busybox- 推送成功后在Harbor的管理界面中就可以查看到busybox镜像了；
- 由于Harbor是用Docker Compose部署的，可以直接使用Docker Compose的命令来停止和启动。
# 停止Harbor
docker-compose stop
# 启动Harbor
docker-compose start结合SpringBoot使用
这里使用之前的mall-tiny-fabric项目来演示下，如何使用Maven插件一键打包并推送到Harbor镜像仓库。- 首先修改项目的
pom.xml文件，修改推送的镜像仓库地址，并添加认证信息即可；
<plugin>
<groupId>io.fabric8</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.33.0</version>
<executions>
<!--如果想在项目打包时构建镜像添加-->
<execution>
<id>build-image</id>
<phase>package</phase>
<goals>
<goal>build</goal>
</goals>
</execution>
</executions>
<configuration>
<!-- Docker 远程管理地址-->
<dockerHost>http://192.168.3.101:2375</dockerHost>
<!-- Docker 推送镜像仓库地址-->
<pushRegistry>http://192.168.3.101:80</pushRegistry>
<!-- 认证信息-->
<authConfig>
<push>
<username>admin</username>
<password>Harbor12345</password>
</push>
</authConfig>
<images>
<image>
<!--由于推送到私有镜像仓库，镜像名需要添加仓库地址-->
<name>192.168.3.101:80/mall-tiny/${project.name}:${project.version}</name>
<!--定义镜像构建行为-->
<build>
<!--定义基础镜像-->
<from>java:8</from>
<args>
<JAR_FILE>${project.build.finalName}.jar</JAR_FILE>
</args>
<!--定义哪些文件拷贝到容器中-->
<assembly>
<!--定义拷贝到容器的目录-->
<targetDir>/</targetDir>
<!--只拷贝生成的jar包-->
<descriptorRef>artifact</descriptorRef>
</assembly>
<!--定义容器启动命令-->
<entryPoint>["java", "-jar","/${project.build.finalName}.jar"]</entryPoint>
<!--定义维护者-->
<maintainer>macrozheng</maintainer>
<!--使用Dockerfile构建时打开-->
<!--<dockerFileDir>${project.basedir}</dockerFileDir>-->
</build>
<!--定义容器启动行为-->
<run>
<!--设置容器名，可采用通配符-->
<containerNamePattern>${project.artifactId}</containerNamePattern>
<!--设置端口映射-->
<ports>
<port>8080:8080</port>
</ports>
<!--设置容器间连接-->
<links>
<link>mysql:db</link>
</links>
<!--设置容器和宿主机目录挂载-->
<volumes>
<bind>
<volume>/etc/localtime:/etc/localtime</volume>
<volume>/mydata/app/${project.artifactId}/logs:/var/logs</volume>
</bind>
</volumes>
</run>
</image>
</images>
</configuration>
</plugin>- 推送镜像之前需要在Harbor中创建好
mall-tiny项目，否则会无法推送镜像；
- 之后使用Maven插件打包镜像并推送到Harbor仓库，具体可以参考《还在手动部署SpringBoot应用？试试这个自动化插件！》，推送过程中输出信息如下；

mall-tiny-fabric镜像已经存在了。
总结
Harbor提供了管理界面让我们可以更方便地管理Docker镜像，同时添加了基于角色的权限管理功能来保护镜像的安全。之前我们为了安全地使用镜像，需要使用繁琐的TLS来控制远程Docker服务打包镜像，具体参考《Docker服务开放了这个端口，服务器分分钟变肉机！》。现在我们只要搭建一个Harbor镜像仓库，然后本地打包好镜像上传到Harbor，需要使用镜像的时候直接从Harbor下载即可！
