使用Docker registry鏡像創(chuàng)建私有倉庫的方法

本篇文章主要介紹了使用Docker registry鏡像創(chuàng)建私有倉庫的方法，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下。

安裝Docker后，可以通過官方提供的registry鏡像來簡單搭建一套本地私有倉庫環(huán)境，本文記錄簡單的搭建過程。

1 使用registry啟動私有倉庫的容器

docker run -d -p 5000:5000 -v /root/my_registry:/tmp/registry registry

說明：若之前沒有安裝registry容器則會自動下載并啟動一個(gè)registry容器，創(chuàng)建本地的私有倉庫服務(wù)。默認(rèn)情況下，會將倉庫創(chuàng)建在容器的/tmp/registry目錄下，可以通過 -v 參數(shù)來將鏡像文件存放在本地的指定路徑上（例如，放在本地目錄/root/my_registry下）。

2 向私有倉庫push鏡像

docker push 104.131.173.242:5000/ubuntu_sshd_gcc_gerry:14.04

說明：根據(jù)第一步啟動的registry容器所在宿主主機(jī)的IP和Port，push某環(huán)境的本地容器。

root@gerryyang:~# docker push 104.131.173.242:5000/ubuntu_sshd_gcc_gerry:14.04 
The push refers to a repository [104.131.173.242:5000/ubuntu_sshd_gcc_gerry] (len: 1)

關(guān)于https的問題

root@gerryyang:~# docker push 104.131.173.242:5000/ubuntu_sshd_gcc_gerry:14.04 
FATA[0002] Error: Invalid registry endpoint https://104.131.173.242:5000/v1/: Get https://104.131.173.242:5000/v1/_ping: EOF. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry 104.131.173.242:5000` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/104.131.173.242:5000/ca.crt

解決方法：

修改Docker配置文件

vim /etc/default/docker

增加以下一行

DOCKER_OPTS="$DOCKER_OPTS --insecure-registry=104.131.173.242:5000"

重啟Docker

sudo service docker restart

3 私有倉庫查詢方法

curl http://104.131.173.242:5000/v1/search

說明：使用curl查看倉庫104.131.173.242:5000中的鏡像。在結(jié)果中可以查看到ubuntu_sshd_gcc_gerry，說明已經(jīng)上傳成功了。

gerryyang@mba:personal_repository$curl http://104.131.173.242:5000/v1/search 
{"num_results": 0, "query": "", "results": []} 
gerryyang@mba:personal_repository$curl http://104.131.173.242:5000/v1/search 
{"num_results": 1, "query": "", "results": [{"description": "", "name": "library/ubuntu_sshd_gcc_gerry"}]}

4 在其他的機(jī)器上訪問和下載私有倉庫的鏡像

docker pull 104.131.173.242:5000/ubuntu_sshd_gcc_gerry:14.04
