首先你需要安裝Harbor服務：
https://blog.csdn.net/qq_50247813/article/details/136388229

客戶端已經安裝docker： https://docs.docker.com/engine/install/centos/

1. 在docker客戶端登錄 Harbor

我的Harbor 服務器地址·： 192.168.44.161 賬號密碼為： zoujiahao/Zou#200101

# docker login 192.168.44.161	# docker logout 登出

使用shell方式登錄：docker login 192.168.44.161 -u zoujiahao -p Zou#200101

# docker login 192.168.44.161
Username: zoujiahao
Password: 
Error response from daemon: Get "https://192.168.44.161/v2/": dial tcp 192.168.44.161:443: connect: connection refused

這里報錯的原因也看到了，沒有證書，所以docker客戶端需要將 Harbor 服務器地址添加到不安全的注冊倉庫列表中。
官方文檔參考： https://distribution.github.io/distribution/about/insecure/

• 修改docker /etc/docker/daemon.json文件

  # cat  /etc/docker/daemon.json
  {"insecure-registries" : ["192.168.44.161"]
  }
  

• 重新加載配置文件，并重啟docker

    # systemctl daemon-reload && systemctl restart docker
  

• 再次登錄

  # docker login 192.168.44.161
  Username: zoujiahao
  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
  

• 上傳鏡像到 Harbor 倉庫

推送格式在Harbor 倉庫中有介紹
docker tag SOURCE_IMAGE[:TAG] 192.168.44.161/zoujiahao/REPOSITORY[:TAG]
docker push 192.168.44.161/zoujiahao/REPOSITORY[:TAG]

# docker pull busybox
# docker tag busybox 192.168.44.161/zoujiahao/busybox:first
# docker push 192.168.44.161/zoujiahao/busybox:first

# docker push 192.168.44.161/zoujiahao/busybox:first
The push refers to repository [192.168.44.161/zoujiahao/busybox]
2e112031b4b9: Pushed 
first: digest: sha256:d319b0e3e1745e504544e931cde012fc5470eba649acc8a7b3607402942e5db7 size: 527

• 在Harbor 控制臺查看
  

• 重新拉取鏡像

    # docker pull 192.168.44.161/zoujiahao/busybox:first
