kubernetes集群公共服务 Harbor

一、 docker-ce安装

1.1 获取YUM源

使用阿里云开源软件镜像站。

# wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo

1.2 安装并设置启动及开机自启动

# yum -y install docker-ce

# systemctl enable --now docker

二、 docker compose安装

下载docker-compose二进制文件
# wget https://github.com/docker/compose/releases/download/1.25.0/docker-compose-Linux-x86_64

查看已下载二进制文件
# ls
docker-compose-Linux-x86_64

移动二进制文件到/usr/bin目录，并更名为docker-compose
# mv docker-compose-Linux-x86_64 /usr/bin/docker-compose

为二进制文件添加可执行权限
# chmod +x /usr/bin/docker-compose

安装完成后，查看docker-compse版本
# docker-compose version
docker-compose version 1.25.0, build 0a186604
docker-py version: 4.1.0
CPython version: 3.7.4
OpenSSL version: OpenSSL 1.1.0l  10 Sep 2019

三、 获取harbor安装文件

3.1 harbor下载

下载harbor离线安装包
# wget https://github.com/goharbor/harbor/releases/download/v2.5.1/harbor-offline-installer-v2.5.1.tgz

查看已下载的离线安装包
# ls
harbor-offline-installer-v2.5.1.tgz

3.2 修改配置文件

解压harbor离线安装包
# tar xf harbor-offline-installer-v2.5.1.tgz

查看解压出来的目录
# ls
harbor 

查看harbor目录
# ls harbor
common.sh  harbor.v2.5.1.tar.gz  harbor.yml.tmpl  install.sh  LICENSE  prepare

创建配置文件
# cd harbor/
# mv harbor.yml.tmpl harbor.yml

修改配置文件内容

# vim harbor.yml

# Configuration file of Harbor

# The IP address or hostname to access admin UI and registry service.
# DO NOT use localhost or 127.0.0.1, because Harbor needs to be accessed by external clients.
hostname: harbor.msb.com

# http related config
http:
  # port for http, default is 80. If https enabled, this port will redirect to https port
  port: 80

# https related config
# https:
  # https port for harbor, default is 443
#  port: 443
  # The path of cert and key files for nginx
#  certificate: /root/harbor/6864844_kubemsb.com.pem 
#  private_key: /root/harbor/6864844_kubemsb.com.key

# # Uncomment following will enable tls communication between all harbor components
# internal_tls:
#   # set enabled to true means internal tls is enabled
#   enabled: true
#   # put your cert and key files on dir
#   dir: /etc/harbor/tls/internal

# Uncomment external_url if you want to enable external proxy
# And when it enabled the hostname will no longer used
# external_url: https://reg.mydomain.com:8433

# The initial password of Harbor admin
# It only works in first time to install harbor
# Remember Change the admin password from UI after launching Harbor.
harbor_admin_password: 12345 访问密码

3.5 验证运行情况

3.6 访问harbor UI界面

直接浏览器访问 harbor主机ip即可跳转

四、配置Docker使用Harbor

配置之前建议把harbor服务停止，修改后再重启

• 命令：docker-compose down
• 主要除了在harbor主机上配置 还需要在K8S集群的三台主机上配置 集群才能访问harbor

# vim /etc/docker/daemon.json

{							
    //这里由于有前面配置有DNS服务，访问也可以用域名 harbor.msb.com
  "insecure-registries": ["http://192.168.10.246"]			
}

• 修改了docker配置文件 需要重启

# systemctl restart docker    

-然后再重启harbor服务 -d表示后台运行

# docker-compose up -d   

验证是否可以使用

提示输入登录账户密码，成功即表示可以访问

# docker login harbor.msb.com

五、上传镜像到harbor服务演示

1.拉取镜像 举例nginx

# docker pull nginx:lastest

2.重新标记新的镜像，用来上传的镜像

• tag 标记 源镜像 目标镜像位置:标记值 library是harbor默认文件夹目录在下面创建nginx目录

#  docker images     //先查看镜像拉取是否成功
#  docker -tag nginx:lastest harbor.msb.com/library/nginx:v1 

3.登录harbor ,进行上传镜像

• 上传成功后，就可以在harbor客户端界面-项目栏目-点击library进入可看到有nginx目录，里面有一个镜像文件了

# docker login harbor.msb.com
# docker push harbor.msb.com/library/nginx:v1
