docker-harbor私有仓库使用笔记

1. 登录harbor管理页面，创建项目，比如yuqx_test

2. admin登录，此处免密登录，正常情况下会输入账号密码

[root@k8s-rancher2 ~]# docker login 1.1.1.1:2021
Authenticating with existing credentials...
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

3. 查看本地镜像列表

[root@k8s-rancher2 ~]# docker images
REPOSITORY                                                                    TAG                     IMAGE ID       CREATED         SIZE

4. 给镜像打tag

[root@k8s-rancher2 ~]# docker tag redis:6.2.5 1.1.1.1:2021/yuqx_test/redis:6.2.5
[root@k8s-rancher2 ~]# docker images
REPOSITORY                                                                    TAG                     IMAGE ID       CREATED         SIZE

5. push到远程仓库

[root@k8s-rancher2 ~]# docker push 1.1.1.1:2021/yuqx_test/redis:6.2.5
The push refers to repository [1.1.1.1:2021/yuqx_test/redis]
0083597d42d1: Pushed
992463b68327: Pushed
4be6d4460d36: Pushed
ec92e47b7c52: Pushed

[root@k8s-rancher2 ~]# 

6. 上传成功后，打开harbor管理页即可看见刚刚上传的redis镜像。（可在成员里添加项目的用户）

7.  退出登录

[root@k8s-rancher2 ~]# docker logout 1.1.1.1:2021
Removing login credentials for 1.1.1.1:2021
[root@k8s-rancher2 ~]#

8. pull远程仓库镜像

[root@k8s-rancher3 ~]# docker login 1.1.1.1:2021

完毕。

常见问题：docker login

[root@web-dev1 yuqx]# docker login 1.1.1.1:2021
Username: admin
Password:
Error response from daemon: Get "https://1.1.1.1:2021/v2/": http: server gave HTTP response to HTTPS client

解决：daemon.json 加入insecure-registries配置，然后重启docker

[root@web-dev1 yuqx]# vim /etc/docker/daemon.json

  1 {
  2     "registry-mirrors": ["https://dockerhub.azk8s.cn","https://hub-mirror.c.163.com"],
  3     "exec-opts": ["native.cgroupdriver=cgroupfs"],
  4     "log-driver": "json-file",
  5     "log-opts": {"max-size": "10m","max-file": "10"},
  6     "insecure-registries":["1.1.1.1:2021"]
  7 }

[root@web-dev1 yuqx]# systemctl restart docker

[root@web-dev1 yuqx]# docker login 1.1.1.1:2021
