7.docker-registry私有仓库

1.下载私有仓库镜像

[root@docker03 ~]# docker pull registry Using default tag: latest latest: Pulling from library/registry c87736221ed0: Pull complete 1cc8e0bb44df: Pull complete 54d33bcb37f5: Pull complete e8afc091c171: Pull complete b4541f6d3db6: Pull complete Digest: sha256:8004747f1e8cd820a148fb7499d71a76d45ff66bac6a29129bfdbfdc0154d146 Status: Downloaded newer image for registry:latest docker.io/library/registry:latest

2.启动镜像

[root@docker03 ~]# docker run -d -p 5000:5000 --restart=always --name registry -v /opt/myregistry:/var/lib/registry registry c167a59c546c90e32bd0f15cc9b219555056d89b0f09af61f4b0e0ae8d930a82

3.第一次上传报错

[root@docker03 ~]# docker tag centos:7 10.0.0.13:5000/centos:7 [root@docker03 ~]# docker push 10.0.0.13:5000/centos The push refers to repository [10.0.0.13:5000/centos] Get server gave HTTP response to HTTPS client

4.默认是/etc/docker/daemon.json { "insecure-registries": ["10.0.0.13:5000"] } #重启docker systemctl restart docker

5.上传(push)镜像测试

root@docker03 ~]# docker push 10.0.0.13:5000/centos:6.9 The push refers to repository [10.0.0.13:5000/cnetos] aaa5621d7c01: Pushed

6.下载(pull)镜像测试

[root@docker03 ~]# docker pull 10.0.0.13:5000/centos:6.9

7.删除私有仓库中的镜像

#进入私有仓库registry [root@docker03 ~]# docker exec -it registry /bin/sh #删除repo ~ # rm -rf /var/lib/registry/docker/registry/v2/repositories/cnetos #清楚掉blob ~ # registry garbage-collect /etc/docker/registry/config.yml

8.把registry加认证

[root@docker03 ~]# yum install -y [root@docker03 ~]# mkdir /opt/registry-var/auth/ -p [root@docker03 ~]# htpasswd -Bbn shuai 123456 >> /opt/registry-var/auth/htpasswd [root@docker03 ~]# docker run -d -p 5000:5000 -v /opt/registry-var/auth/:/auth/ -v /opt/myregistry:/var/lib/registry -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd registry #没有认证无法上传 [root@docker03 ~]# docker tag centos:latest 10.0.0.13:5000/centos:7 [root@docker03 ~]# docker push 10.0.0.13:5000/centos:7 The push refers to repository [10.0.0.13:5000/centos] 9e607bb861a7: Preparing no basic auth credentials #登陆上传 [root@docker03 ~]# docker login 10.0.0.13:5000 Username: shuai Password: WARNING!

9.密码文件目录

[root@docker03 ~]# cat /root/.docker/config.json { "auths": { "10.0.0.13:5000": { "auth": "c2h1YWk6MTIzNDU2" } }, "HttpHeaders": { "User-Agent": "Docker-Client/19.03.3 (linux)" } #使用base64认证c2h1YWk6MTIzNDU2=shuai:123456
