本文主要是介绍给init类linux系统的docker pull 设置拉取镜像的代理，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
如何判断自己是哪个类型的linux 系统，用如下命令查看：
ps --no-headers -o comm 1输出将显示当前使用的初始化系统，例如 systemd、init。
如果是systemd linux系统请参考如下link 做这件事

在写本文时，系统输出是init，以下时设置方法的记录：
docker 拉取镜像的代理设置文件路径在：/etc/default/docker
编辑配置文件并添加代理环境变量：
sudo nano /etc/default/docker在文件中插入以下行：
# Docker SysVinit configuration file#
# THIS FILE DOES NOT APPLY TO SYSTEMD
#
# Please see the documentation for "systemd drop-ins":
# https://docs.docker.com/engine/admin/systemd/
## Customize location of Docker binary (especially for development testing).
#DOCKERD="/usr/local/bin/dockerd"# Use DOCKER_OPTS to modify the daemon startup options.
#DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"# If you need Docker to use an HTTP proxy, it can also be specified here.
#export http_proxy="http://127.0.0.1:3128/"
export http_proxy="http://your_http_proxy_server_ip:your_port"
export https_proxy="http://your_http_proxy_server_ip:your_port"# This is also a handy place to tweak where Docker's temporary files go.
#export DOCKER_TMPDIR="/mnt/bigdrive/docker-tmp"保存并关闭文件后，重启 Docker 服务：
sudo service docker restart从 docker info 的结果中查看代理配置项，看到 HTTP Proxy: 和 HTTPS Proxy:两个关键字代表设置成功了。
sudo docker info

Status: Downloaded newer image for hello-world:latestHello from Docker!
This message shows that your installation appears to be working correctly.To generate this message, Docker took the following steps:1. The Docker client contacted the Docker daemon.2. The Docker daemon pulled the "hello-world" image from the Docker Hub.(amd64)3. The Docker daemon created a new container from that image which runs theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, which sent itto your terminal.To try something more ambitious, you can run an Ubuntu container with:$ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID:https://hub.docker.com/For more examples and ideas, visit:https://docs.docker.com/get-started/这篇关于给init类linux系统的docker pull 设置拉取镜像的代理的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
