docker harbor镜像仓库

docker harbor安装使用：

https://github.com/goharbor/harbor/releases

有离线安装和在线安装两种方式

安装：

1、下载安装包

https://github.com/goharbor/harbor/releases

在线安装包，体积小：

wget https://storage.googleapis.com/harbor-releases/release-1.8.0/harbor-online-installer-v1.8.1.tgz

离线安装包，体积大：

wget https://storage.googleapis.com/harbor-releases/release-1.8.0/harbor-offline-installer-v1.8.1.tgz

2、修改配置文件

tar -xvf harbor-online-installer-v1.8.1.tgz

cd harbor/

vim harbor.yml

hostname: 118.xxx.xxx.xxx    #主机名，可以是域名和IP

port: 80    #访问端口，做了ssl域名正式可以设置成443

harbor_admin_password: Harbor12345   #harbor页面等登录密码

database:

  password: root123    #数据库密码

data_volume: /data  #数据卷的路径，是本机的真实路径

3、下载docker-compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

4、执行安装脚本

./install.sh

5、登录harbor界面

http://ip

用户名：admin

密码：Harbor12345

 

6、启动和停止harbor

cd harbor#启动和停止harbor需要找docker-compose.yml文件，所以必须进入harbor安装目或者-f指定harbor项目的docker-compose.yml

docker-compose start/stop

7、推送镜像

docker tag SOURCE_IMAGE[:TAG] 118.xxx.xxx.xxx/myproject/IMAGE[:TAG] #打标签

docker push 118.xxx.xxx.xxx/myproject/IMAGE[:TAG] #推送

推送执行时报错：

1) The push refers to repository 118.xxx.xxx.xxx/myproject/nginx]

Get https://118.xxx.xxx.xxx/v2/: dial tcp 118.xxx.xxx.xxx:443: connect: connection refused

这是因为默认情况下访问的是443端口,需要证书认证，我们没有，需要在配置文件中添加仓库安全地址

[root@VM_0_3_centos harbor]# cat /etc/docker/daemon.json

{"registry-mirrors": ["http://f1361db2.m.daocloud.io"],

"insecure-registries": ["118.xxx.xxx.xxx"]

}

2) The push refers to repository [118.xxx.xxx.xxx/myproject/nginx]

d7acf794921f: Preparing

d9569ca04881: Preparing

cf5b3c6798f7: Preparing

denied: requested access to the resource is denied

因为我们创建的项目是私有项目，需要登录之后才能上传镜像

[root@VM_0_3_centos ~]# docker login 118.xxx.xxx.xxx

Username: admin

Password:#如果没有改动过，admin密码是Harbor12345，也可以在harbor上为项目创建一个用户

3) docker login发生错误

Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

需要给docker添加dns配置

[root@VM_0_3_centos harbor]# cat /etc/docker/daemon.json

{"registry-mirrors": ["http://f1361db2.m.daocloud.io"],

"insecure-registries": ["118.xxx.xxx.xxx"],

"dns":["8.8.8.8","114.114.114.114"]

}
