# **Docker的安裝及如何配置從國內鏡像中拖取須要的images到本地使用**node

實驗環境：python

OS:CentOS7.0 -X64linux

上網環境：經過代理服務器上網nginx

1.首先下載docker安裝包docker

下載docker安裝所需的插件：vim

docker-engine-selinux-1.9.1-1.e17.centos.noarch.rpmcentos

下載地址：http://yum.dockerproject.org/repo/main/centos/7/Packages/服務器

docker-engine-1.9.1.1.e17.centos.x86_64.rpmapp

下載地址：http://yum.dockerproject.org/repo/main/centos/7/Packages/ ide

2.安裝docker

先查看下載下來的安裝包：

[root@docker docker]# pwd

/docker

[root@docker docker]# ls

docker-engine-1.9.1-1.el7.centos.x86_64.rpm docker-engine-selinux-1.9.1-1.el7.centos.noarch.rpm

[root@docker docker]# rpm -ivh docker-engine*

warning: docker-engine-1.9.1-1.el7.centos.x86_64.rpm: Header V4 RSA/SHA512 Signature, key ID 2c52609d: NOKEY

error: Failed dependencies:

policycoreutils-python is needed by docker-engine-selinux-1.9.1-1.el7.centos.noarch

安裝提示缺乏policycoreutils-python組件

[root@docker docker]# yum install -y policycoreutils-python （經過光盤yum源就能夠直接安裝該組件）

[root@docker docker]# rpm -ivh docker-engine* 再次安裝docker，成功安裝

2．配置服務器代理上網：因爲上網環境是經過代理上網，因此本臺測試機器須要配置代理才能夠上網。

配置方法以下：編輯/etc/profile 添加如下內容

http_proxy=192.168.1.100:8005 #根據實際狀況設定本身的代理服務器

https_proxy=$http_proxy

http_proxy_username=test #若是代理須要經過用戶名和密碼驗證則設置，若是不須要驗證username和password則能夠不設定。

http_proxy_password=12356

no_proxy=192.*.*.*,*.local,localhost,127.0.0.1 #設定不須要代理的ip

[root@docker ~]# ping baidu.com #測試ping百度，鏈接成功，配置外網代理成功。

PING baidu.com (220.181.57.216) 56(84) bytes of data.

64 bytes from 220.181.57.216 (220.181.57.216): icmp_seq=1 ttl=51 time=30.7 ms

64 bytes from 220.181.57.216 (220.181.57.216): icmp_seq=2 ttl=51 time=33.4 ms

64 bytes from 220.181.57.216 (220.181.57.216): icmp_seq=3 ttl=51 time=34.0 ms

覺得經過上述設定就能夠經過 docker pull [images名稱] 下載docker鏡像文件，結果報如下錯誤：

[root@docker ~]# docker pull daocloud.io/library/node:8.1.0-slim #經過pull命令，提示的報錯，反正我也沒看懂，因此就網上搜索

一下，找了不少方法，總算找到了緣由，是因爲docker須要再單獨配置代理上網。

Error response from daemon: invalid registry endpoint https://daocloud.io/v0/: unable to ping registry endpoint https://daocloud.io/v0/

v2 ping attempt failed with error: Get https://daocloud.io/v2/: remote error: handshake failure

v1 ping attempt failed with error: Get https://daocloud.io/v1/_ping: remote error: handshake failure. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry daocloud.io` 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/daocloud.io/ca.crt

3．配置docker代理上網，新增如下配置文件

[root@docker ~]# vim /etc/systemd/system/docker.service.d/http-proxy.conf #新增代理配置文件，內容以下：

[Service]

Environment="HTTP_PROXY=10.109.134.247:8005"

Environment="NO_PROXY=localhost,127.0.0.0/8,docker-registry.somecorporation.com"

保存退出，再次使用pull命令下載成功，能夠使用pull命令下載鏡像了，總算搞定了。

[root@docker ~]# systemctl daemon-reload #從新加載daemon

[root@docker ~]# systemctl show docker --property Environment #查看設置的代理環境是否成功。

Environment=HTTP_PROXY=192.168.1.100:8005 NO_PROXY=localhost,127.0.0.0/8,docker-registry.somecorporation.com

[root@docker ~]# systemctl restart docker #或者直接service docker restart 重啓docker服務。

Starting docker (via systemctl): [ OK ]

[root@docker ~]# docker images #查看docker鏡像文件，初始安裝沒有鏡像
