| 导读 | 创建docker私有仓库的目的在于私密性，适用于团体内部，如公司部门，企业内部等需要在团体成员中共享docker相关资源的场景。 那么如何搭建属于自己企业或团体成员可以使用的docker私有仓库呢？笔者将通过下面的实际搭建流程结合步骤描述来介绍docker私有仓库搭建的具体过程。 |
1、下载registry镜像
[root@localhost ~]# docker pull registry Using default tag: latest latest: Pulling from library/registry 486039affc0a: Pull complete ba51a3b098e6: Pull complete 8bb4c43d6c8e: Pull complete 6f5f453e5f2d: Pull complete 42bc10b72f42: Pull complete Digest: sha256:7d081088e4bfd632a88e3f3bcd9e007ef44a796fddfe3261407a3f9f04abe1e7 Status: Downloaded newer image for registry:latest docker.io/library/registry:latest
2、生成registry容器，开放5000端口
[root@localhost ~]# docker create -it registry /bin/bash
fd51aa59dc5cea7b589d0403e562cb8f0098c3a8a7da239572dd5bfd9423ec96
[root@localhost ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
fd51aa59dc5c registry "/entrypoint.sh /bin…" 10 seconds ago Created optimistic_saha
#建议直接执行下面的这个，因为笔者遇到start这个容器发现退出的状态码非0（后面解决了，使用/bin/sh环境即可）
[root@localhost ~]# docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry
ceb498d622ab743fc858a993e3870f9831e20436cb71f7225215f1f0899571f1
[root@localhost ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ceb498d622ab registry "/entrypoint.sh /etc…" 2 seconds ago Up 2 seconds 0.0.0.0:5000->5000/tcp strange_swanson
docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry的解释：
-d ——守护进程
-v ——数据卷设置{/data/registry表示的宿主机系统中的一个绝对路径，没有的时候会自动创建，/tmp/registry表示容器内部的目录}
#宿主机目录
[root@localhost ~]# ls /
bin boot data dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var
[root@localhost ~]# ls /data/
registry
#容器内部目录
[root@localhost ~]# docker exec -it ceb498d622ab /bin/sh
/ # ls /
bin etc media root srv usr
dev home mnt run sys var
entrypoint.sh lib proc sbin tmp
/ # ls tmp/
registry
3、客户端设置daemon.json文件 （指定私有仓库位置）
[root@localhost ~]# vim /etc/docker/daemon.json
{
"insecure-registries": ["20.0.0.149:5000"], #将本地服务器作为私有仓库位置
"registry-mirrors": ["//5m9y9qbl.mirror.aliyuncs.com"]
}
[root@localhost ~]# systemctl restart docker
4、创建本地的镜像标签
[root@localhost ~]# docker pull httpd Using default tag: latest latest: Pulling from library/httpd 123275d6e508: Pull complete e984dd982a6e: Pull complete 963280e5cf81: Pull complete 6faf90d050b2: Pull complete 962b56984bb0: Pull complete Digest: sha256:d5dc0d279039da76a8b490d89a5c96da83a33842493d4336b42ccdfbd36d7409 Status: Downloaded newer image for httpd:latest docker.io/library/httpd:latest [root@localhost ~]# docker tag httpd:latest 20.0.0.149:5000/httpd
5、上传镜像
[root@localhost ~]# docker push 149:5000/httpd
The push refers to repository [149:5000/httpd]
An image does not exist locally with the tag: 149:5000/httpd
[root@localhost ~]# docker push 20.0.0.149:5000/httpd
The push refers to repository [20.0.0.149:5000/httpd]
9dabb51b1ca2: Pushed
4621e8a6d1da: Pushed
e728c649bc91: Pushed
1a935e59aa8a: Pushed
b60e5c3bcef2: Pushed
latest: digest: sha256:8f10edef61246c6c142a87304d4ffa68298662ecb619776e4e9817d06ec5f567 size: 1367
[root@localhost ~]# curl -XGET //20.0.0.149:5000/v2/_catalog
{"repositories":["httpd"]}
#有上面的结果表示上传成功
6、下载镜像测试
[root@localhost ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE httpd latest bdc169d27d36 Less than a second ago 166MB 20.0.0.149:5000/httpd latest bdc169d27d36 Less than a second ago 166MB registry latest 708bc6af7e5e 2 months ago 25.8MB [root@localhost ~]# docker rmi bdc169d27d36 Error response from daemon: conflict: unable to delete bdc169d27d36 (must be forced) - image is referenced in multiple repositories [root@localhost ~]# docker rmi bdc169d27d36 -f Untagged: 20.0.0.149:5000/httpd:latest Untagged: 20.0.0.149:5000/httpd@sha256:8f10edef61246c6c142a87304d4ffa68298662ecb619776e4e9817d06ec5f567 Untagged: httpd:latest Untagged: httpd@sha256:d5dc0d279039da76a8b490d89a5c96da83a33842493d4336b42ccdfbd36d7409 Deleted: sha256:bdc169d27d36e2438ec8452c7dd7a52a05561b5de7bef8391849b0513a6f774b Deleted: sha256:6535aa332fb72ca508f550fef8ffb832d4c6bc72a48720b42659e10d47668181 Deleted: sha256:c7bce1fab718a11501a672c895a729b1fdf8099d00fe152bef8c2534ee455976 Deleted: sha256:75b6b2392924b062257ed97e5c2f3aa9f50a922b94c3f7c342d0aed2370e8bec Deleted: sha256:267e2020b1bd0b182eb02d1a0f3e2f72efc542890ef6159ed9c3570322608de0 Deleted: sha256:b60e5c3bcef2f42ec42648b3acf7baf6de1fa780ca16d9180f3b4a3f266fe7bc [root@localhost ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE registry latest 708bc6af7e5e 2 months ago 25.8MB [root@localhost ~]#
测试：
[root@localhost ~]# docker pull 20.0.0.149:5000/httpd Using default tag: latest latest: Pulling from httpd 123275d6e508: Pull complete e984dd982a6e: Pull complete 963280e5cf81: Pull complete 6faf90d050b2: Pull complete 962b56984bb0: Pull complete Digest: sha256:8f10edef61246c6c142a87304d4ffa68298662ecb619776e4e9817d06ec5f567 Status: Downloaded newer image for 20.0.0.149:5000/httpd:latest 20.0.0.149:5000/httpd:latest [root@localhost ~]#
拉取成功并且拉取镜像的速度很快。
最后给出上面出现的状态码错误的问题具体解决：
