摘要：安裝Docker後，可以通過官方提供的registry映象來簡單搭建一套本地私有倉庫環境，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容器則會自動下載並啟動一個registry容器，建立本地的私有倉庫服務。預設情況下，會將倉庫建立在容器的/tmp/registry目錄下，可以通過 -v 引數來將映象檔案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映象

docker push 104.131.173.242:5000/ubuntu_sshd_gcc_gerry:14.04
說明：根據第一步啟動的registry容器所在宿主主機的IP和Port，push某環境的本地容器。

[email protected]:~# 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)

關於https的問題

[email protected]:~# 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 

3 私有倉庫查詢方法

curl http://104.131.173.242:5000/v1/search
說明：使用curl檢視倉庫104.131.173.242:5000中的映象。在結果中可以檢視到ubuntu_sshd_gcc_gerry，說明已經上傳成功了。

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

4 在其他的機器上訪問和下載私有倉庫的映象

docker pull 104.131.173.242:5000/ubuntu_sshd_gcc_gerry:14.04
