【Docker】企业级镜像仓库harbor的搭建(http/https)及使用

一：用途###

Harbor是一个用于存储和分发Docker镜像的企业级Registry服务器。

二：安装docker-ce###

环境：阿里云轻量应用服务器CentOS 7.3
这里通过yum Docker源仓库安装：
①安装yum 管理依赖包

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

②添加Docker 源仓库

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

③安装Docker CE

sudo yum install docker-ce docker-ce-cli containerd.io

三：安装docker-compose###

参考这篇博客：https://www.cnblogs.com/wucaiyun1/p/11811112.html

四：安装harbor###

https://github.com/goharbor/harbor/blob/master/docs/installation_guide.md
①下载harbor

wget https://storage.googleapis.com/harbor-releases/harbor-offline-installer-v1.6.1.tgz

或者到github releases下载
https://github.com/goharbor/harbor/releases
-------------------------------------------------------------------http方式-------------------------------------------------------------------
②配置安装(http方式)

[root@iZuf6hcb8yumasfp52oemxZ ailala]# tar -xf harbor-offline-installer-v1.6.1.tgz 
[root@iZuf6hcb8yumasfp52oemxZ ailala]# cd harbor
[root@iZuf6hcb8yumasfp52oemxZ harbor]# vi harbor.yml

-------------------------------------------------------------------http方式-------------------------------------------------------------------
-------------------------------------------------------------------https方式-------------------------------------------------------------------
②配置安装(https方式)

Getting Certificate Authority####

openssl genrsa -out ca.key 4096

openssl req -x509 -new -nodes -sha512 -days 3650 \
-subj "/C=CN/ST=Shanghai/L=Shanghai/O=example/OU=Personal/CN=fixedbug.work" \
-key ca.key \
-out ca.crt

Getting Server Certificate####

1. Create your own Private Key:

openssl genrsa -out fixedbug.work.key 4096

2. Generate a Certificate Signing Request:

openssl req -sha512 -new \
    -subj "/C=CN/ST=Shanghai/L=Shanghai/O=example/OU=Personal/CN=fixedbug.work" \
    -key fixedbug.work.key \
    -out fixedbug.work.csr

3. Generate the certificate of your registry host:

cat > v3.ext <<-EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names

[alt_names]
DNS.1=fixedbug.work
DNS.2=fixedbug
DNS.3=hostname
EOF

openssl x509 -req -sha512 -days 3650 \
    -extfile v3.ext \
    -CA ca.crt -CAkey ca.key -CAcreateserial \
    -in fixedbug.work.csr \
    -out fixedbug.work.crt

Configuration and Installation####

1. Configure Server Certificate and Key for Harbor

  cp yourdomain.com.crt /data/cert/
  cp yourdomain.com.key /data/cert/

2. Configure Server Certificate, Key and CA for Docker
   Convert server yourdomain.com.crt to yourdomain.com.cert:

openssl x509 -inform PEM -in fixedbug.work.crt -out fixedbug.work.cert

Delpoy yourdomain.com.cert, yourdomain.com.key, and ca.crt for Docker:

  cp yourdomain.com.cert /etc/docker/certs.d/yourdomain.com/
  cp yourdomain.com.key /etc/docker/certs.d/yourdomain.com/
  cp ca.crt /etc/docker/certs.d/yourdomain.com/

/etc/docker/certs.d/
    └── yourdomain.com:port
       ├── yourdomain.com.cert  <-- Server certificate signed by CA
       ├── yourdomain.com.key   <-- Server key signed by CA
       └── ca.crt               <-- Certificate authority that signed the registry certificate

3. Configure Harbor
   
   -------------------------------------------------------------------https方式-------------------------------------------------------------------

[root@iZuf6hcb8yumasfp52oemxZ harbor]# ./prepare

[root@iZuf6hcb8yumasfp52oemxZ harbor]# ./install

③登录

五：上传镜像到harbor仓库###

在本机配置harbor仓库http可信
/etc/docker/daemon.json中添加“"insecure-registries":["reg.slito.com"]”，不然会报错，默认是走https的，重启docker；

登录harbor仓库

[root@iZuf6hcb8yumasfp52oemxZ harbor]# docker login fixedbug.work:88
Username: admin

踩坑记录：域名只是用来替代IP的，没有备案会封锁对应IP的80和433端口，这个IP必须是国内的才行。如果域名指向国外IP，备案还是不备案都不妨碍80和433端口的使用。
