    There are several ways to clone a repository from github. Similar from other providers, such as bitbucket, gitlab, etc.
https://git-scm.com/book/en/v2/Git-on-the-Server-The-Protocols
Mostly, we use

http
ssh

Sample clone commands:

The clone command with protocol https
git clone https://github.com/kubernetes/kubernetes.git

The clone command with protocol ssh+git
git clone git@github.com:kubernetes/kubernetes.git

Work with ssh config

When we are behind proxy, I have to set ssh config (~/.ssh/config) with ProxyCommand properly, git clone start working with proxy.
Install corkscrew or other proxy tool first.
with this way, we don't need provide username and password each time when clone the repository behind proxy

set ssh config
Host github.com
    Hostname github.com
    ServerAliveInterval 55
    ForwardAgent yes
    ProxyCommand /usr/bin/corkscrew <replace_with_your_company_proxy_server> <3128> %h %p

need write down username and password for your proxy.

In some company policies, the password need be changed every 90 days, so don't remember to update this configuration file when your proxy password is changed.
cat ~/.ssh/myauth
proxyUsername:proxyPassword

set ssh config
Host github.com
    Hostname github.com
    ServerAliveInterval 55
    ForwardAgent yes
    ProxyCommand /usr/bin/corkscrew <replace_with_your_company_proxy_server> <3128> %h %p ~/.ssh/myauth

Work with http/https

update ~/.gitconfig
[http]
[http "https://github.com"]
	proxy = http://proxyUsername:proxyPassword@proxy.server.com:port
	sslVerify = false

sslVerify setting is not necessary.
Notes:

If you only need access github by the way of ssh+git, you needn't set any proxy in ~/.gitconfig and run git config --global http.proxy ... and similar commands at all
