harbor仓库的搭建

---

前言

Harbor是一个开源的容器镜像仓库，它提供了一个安全、可靠的平台来存储和分发Docker镜像。与Docker Hub不同的是，Harbor允许用户将私有镜像存储在本地环境中，并且能够对镜像进行访问控制和审计等管理操作，可以帮助组织更好地管理和保护他们的镜像资源，也更适合在企业内部使用。
Harbor支持各种云平台和容器管理平台，如Docker、Kubernetes、Mesos等，同时还支持LDAP、AD等多种认证方式。它还具备高可用性、数据备份、镜像复制等特性，可以满足复杂的部署需求。

一、准备

官方仓库：https://hub.docker.com

配置镜像加速器
[root@k8s1 ~]# vim /etc/docker/daemon.json
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}

[root@k8s1 ~]# systemctl restart docker

[root@k8s1 ~]# docker info

二、registry私有仓库

拉取registry镜像

[root@k8s1 ~]# docker pull registry
运行registry仓库
[root@k8s1 docker]# docker run -d -p 5000:5000 --restart=always --name registry registry

上传镜像

[root@k8s1 ~]# docker tag nginx:latest localhost:5000/nginx:latest
[root@k8s1 ~]# docker push localhost:5000/nginx

[root@k8s1 ~]# curl  localhost:5000/v2/_catalog
{"repositories":["nginx"]}

下载镜像

[root@k8s1 ~]# docker pull localhost:5000/nginx

insecure registry

添加私有仓库解析

[root@k8s2 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.171  k8s1 reg.westos.org
192.168.56.172  k8s2

配置使用非加密端口

[root@k8s2 ~]# vim /etc/docker/daemon.json
{
  "insecure-registries" : ["reg.westos.org:5000"]
}

[root@k8s2 docker]# systemctl  restart docker

拉取镜像

[root@k8s2 docker]# docker pull reg.westos.org:5000/nginx

三、仓库加密

升级软件包

[root@k8s1 ~]# yum install -y openssl11-1.1.1k-2.el7.x86_64.rpm openssl11-libs-1.1.1k-2.el7.x86_64.rpm

[root@k8s1 ~]# mkdir certs
[root@k8s1 ~]# openssl11 req -newkey rsa:4096 -nodes -sha256 -keyout certs/westos.org.key -addext "subjectAltName = DNS:reg.westos.org" -x509 -days 365 -out certs/westos.org.crt

域名保持一致

[root@k8s1 ~]# docker run -d -p 443:443 --restart=always --name registry -v /opt/registry:/var/lib/registry -v /root/certs:/certs -e REGISTRY_HTTP_ADDR=0.0.0.0:443 -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/westos.org.crt -e REGISTRY_HTTP_TLS_KEY=/certs/westos.org.key registry

部署客户端证书，不然会报错

[root@k8s1 ~]# docker tag nginx:latest reg.westos.org/nginx:latest
[root@k8s1 ~]# docker push reg.westos.org/nginx:latest                                                                                             The push refers to repository [reg.westos.org/nginx]
Get "https://reg.westos.org/v2/": x509: certificate signed by unknown authority

[root@k8s1 ~]# mkdir -p /etc/docker/certs.d/reg.westos.org/
[root@k8s1 ~]# cp /root/certs/westos.org.crt /etc/docker/certs.d/reg.westos.org/ca.crt

验证

[root@k8s1 ~]# docker push reg.westos.org/nginx:latest

[root@k8s1 reg.westos.org]# curl -k https://reg.westos.org/v2/_catalog
{"repositories":["nginx"]}

仓库认证

[root@k8s1 ~]# yum install -y httpd-tools
[root@k8s1 ~]# mkdir auth
[root@k8s1 ~]# htpasswd -Bc auth/htpasswd admin
New password:
Re-type new password:
Adding password for user admin

[root@k8s1 ~]# htpasswd -B auth/htpasswd wxh
New password:
Re-type new password:
Adding password for user wxh

[root@k8s1 ~]# cat auth/htpasswd
admin:$2y$05$Wm2LHttPY5a6i2KMG0fShe92d/PjnaBbGitiClcE3wqHmwO8dIDFm
wxh:$2y$05$9rE9CXyZ1fdcMammhh7f6.soDHgKdSsi0DXBgkRW5sKRw5sEJo1lK

删除registry，重建

[root@k8s1 ~]# docker rm -f registry
[root@k8s1 ~]# docker run -d -p 443:443 --restart=always --name registry -v /opt/registry:/var/lib/registry -v /root/certs:/certs -e REGISTRY_HTTP_ADDR=0.0.0.0:443 -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/westos.org.crt -e REGISTRY_HTTP_TLS_KEY=/certs/westos.org.key -v /root/auth:/auth -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd registry

登录仓库，不然无法上传下载

[root@k8s1 ~]# docker login reg.westos.org
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
[root@k8s1 ~]# cat .docker/config.json
{
        "auths": {
                "reg.westos.org": {
                        "auth": "YWRtaW46d2VzdG9z"
                }
        }
}

验证

[root@k8s1 ~]# docker tag busybox:latest reg.westos.org/busybox:latest
[root@k8s1 ~]# docker push reg.westos.org/busybox:latest

[root@k8s1 ~]# curl -k https://reg.westos.org/v2/_catalog  -u admin:westos
{"repositories":["busybox","nginx"]}

登出
[root@k8s1 ~]# docker logout reg.westos.org

四、harbor企业级私有仓库

删除之前部署的registry，不然会冲突

[root@k8s1 ~]# docker rm -f registry

[root@k8s1 ~]# tar zxf harbor-offline-installer-v2.5.0.tgz
[root@k8s1 ~]# cd harbor/
[root@k8s1 harbor]# cp harbor.yml.tmpl harbor.yml
[root@k8s1 harbor]# vim harbor.yml
hostname: reg.westos.org

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

https:
  # https port for harbor, default is 443
  port: 443
  # The path of cert and key files for nginx
  certificate: /data/certs/westos.org.crt
  private_key: /data/certs/westos.org.key

harbor_admin_password: westos

拷贝证书

[root@k8s1 ~ ]# mkdir /data
[root@k8s1 ~ ]# cp -r certs /data

部署docker-compose

[root@k8s1 ~]# mv docker-compose-linux-x86_64-v2.5.0 /usr/local/bin/docker-compose
[root@k8s1 ~]# chmod +x /usr/local/bin/docker-compose

部署harbor

[root@k8s1 harbor]# ./install.sh --with-chartmuseum

使用浏览器登录仓库 用户名：admin 密码是上面配置文件设置的westos

上传镜像，首先需要执行docker login

[root@k8s1 ~]# docker push reg.westos.org/library/nginx:latest
[root@k8s1 ~]# docker push reg.westos.org/library/busybox:latest

客户端配置默认私有仓库

[root@k8s2 ~]# vim /etc/docker/daemon.json
{
        "registry-mirrors": ["https://reg.westos.org"]
}

[root@k8s2 ~]# systemctl  restart docker

匿名拉取镜像

[root@k8s2 ~]# docker pull nginx

创建私有仓库

私有仓库上传和下载镜像都需要用户认证

[root@k8s2 ~]# docker login reg.westos.org

从私有仓库下载时需要指定仓库地址

[root@k8s2 ~]# docker pull reg.westos.org/westos/game2048:latest
