docker镜像下载

场景：

最近在搭建ELK环境，镜像下载出问题，找了一下解决方案做一下记录。

---

修改DNS配置文件

sudo vim /etc/resolv.conf

; generated by /usr/sbin/dhclient-script
nameserver 114.114.114.114.
nameserver 8.8.8.8
options edns0 trust-ad
search localdomain

修改镜像源

vim /etc/docker/daemon.json

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF' 
{
     "max-concurrent-downloads": 10,
     "max-concurrent-uploads": 5,
     "default-shm-size": "1G",
     "debug": true,
     "experimental": false,
     "registry-mirrors":[

}
