Submit code to github using ssh

Recently, I wanted to put a project I wrote on github.
So I built a warehouse on github. A. Local project location D:/code.

Submit code locally

cd D:/code
git init
git add .
git commit -m 'first commit'
Set up a remote repository
git remote add origin [email protected]:sangyuruo/A.git
commit to remote
git push origin master

An error is reported here, you need to set the ssh key.

ssh key set
general my ssh key:

ssh-keygen -t rsa -b 4096 -C "[email protected]" -f ~/.ssh/sangyuruo_rsa

add my key:

ssh-add ~/.ssh/sangyuruo_rsa

View the content of the public key:
cat ~/.ssh/sangyuruo_rsa.pub

Add the public key to github:
deploy keys -> add deploy key

Push again successfully

git push origin master

Get the code from github

git pull origin master
