一、添docker子配置档设置

1、创建目录

mkdir /etc/systemd/system/docker.service.d

2、创建http-proxy.conf文件,增加以下内容

cat > /etc/systemd/system/docker.service.d/http-proxy.conf <<EOF

[Service]

Environment=“HTTP_PROXY=http://192.168.0.2:8118”

Environment=“HTTPS_PROXY=http://192.168.0.2:8118”

Environment=“NO_PROXY=localhost,127.0.0.1,registry.onlymin.com,reg.onlymin.com”

EOF

或

cat > /etc/systemd/system/docker.service.d/http-proxy.conf <<EOF

[Service]

Environment=“HTTP_PROXY=http://192.168.1.91:3128” “NO_PROXY=localhost,127.0.0.1”

EOF

3、Daemon重新reload 并重启docker

systemctl daemon-reload

systemctl restart docker

4、检查变量是否加载

systemctl show docker --property Environment

Environment=“HTTP_PROXY=http://192.168.1.91:3128” “NO_PROXY=localhost,127.0.0.1”

5、取消代理

rm /etc/systemd/system/docker.service.d/http-proxy.conf -rf

systemctl daemon-reload

systemctl restart docker

systemctl show docker --property Environment

二、通过修改docker.service配置设置

1、编辑docker.service

vim /usr/lib/systemd/system/docker.service

在[Service]配置项内添加以下内容：

Environment="HTTP_PROXY=代理url"

Environment="HTTPS_PROXY=代理url"

2、重启docker.service服务

systemctl daemon-reload

systemctl restart docker.service

3、最后测试docker是否可以联网

docker run -it openshift/hello-openshift
