docker安装及网络代理配置

发表于

背景

在一些实验室环境，服务器没有直接连接外网的权限，即便安装好了docker之后，还需要通过网络代理。

内网服务器如何上网,可以通过squid进行代理.

安装docker-ce(通过库安装)

配置库

1.安装所需的软件包, yum-utils、device-mapper-persistent-data和 lvm2

升级Docker CE

下载较新的软件包文件并重复安装，使用yum -y upgrade，并指向新文件。

卸载 Docker CE

$ sudo yum remove docker-ce

$ sudo rm -rf /var/lib/docke

该方法是持久化的，修改后会一直生效。该方法覆盖了默认的docker.service文件
1. 为docker服务创建一个内嵌的systemd目录
$ mkdir -p /etc/systemd/system/docker.service.d

2. 创建/etc/systemd/system/docker.service.d/http-proxy.conf文件，并添加HTTP_PROXY环境变量。其中[proxy-addr]和[proxy-port]分别改成实际情况的代理地址和端口：

[Service]
Environment="HTTP_PROXY=http://[proxy-addr]:[proxy-port]/" "HTTPS_PROXY=https://[proxy-addr]:[proxy-port]/"

3. 如果还有内部的不需要使用代理来访问的Docker registries，那么嗨需要制定NO_PROXY环境变量：

[Service]
Environment="HTTP_PROXY=http://[proxy-addr]:[proxy-port]/" "HTTPS_PROXY=https://[proxy-addr]:[proxy-port]/" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com"

4. 更新配置：
$ systemctl daemon-reload

5. 重启Docker服务：
$ systemctl restart docker
