一些零散笔记

alpine修改镜像(阿里云)

sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories

kubectl自动补全与别名

$ echo "source <(sudo kubectl completion bash | sed 's|__start_kubectl kubectl|__start_kubectl k|g')" >> ~/.bashrc
$ source ~/.bashrc

配置docker的镜像加速

$ vi /etc/docker/daemon.json  

//添加以下内容
{
     "registry-mirrors": ["https://hub-mirror.c.163.com"]
}

CentOS7 yum源

备份原有的yum源文件

cd /etc/yum.repos.d/ && mv CentOS-Base.repo CentOS-Base.repo_bak

阿里云

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

epel源

yum -y install epel-release

最后 yum clean all && yum makecache
