Setup SSH keys for Github/Gogs

setup.md

Instuctions to setup passwordless git operations.

• Generate SSH key pairs (email must be the same you see with : git config user.email)

Select save default to ~/.ssh/id_rsa When ask for pass hit enter , else you must type that pass everytime you use the keys.

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

id_rsa.pub --> public key id_rsa --> private key

• GITHUB Copy the contents of the file ~/.ssh/id_rsa.pub to your SSH keys in your GitHub account settings (https://github.com/settings/keys).

• GOGS Copy the contents of the file ~/.ssh/id_rsa.pub to your SSH keys in your GitHub account settings (https://<GOGS_PUBLIC_URL>/user/settings/ssh).

• Create file ~/.ssh/config

Host <Custom Host>
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa
  IdentitiesOnly yes
#example 
Host local
  HostName 10.10.1.1 # ip of custom gogs , can be github.com or any git server
  User git  # git user
  IdentityFile ~/.ssh/id_rsa # our private key
  IdentitiesOnly yes # tells to git should only use the authentication identity files above 
 #exampleEnd

Update existing repo with remote ( key enabled access )

git remote set-url origin git@<Custom Host>:username/your-repository.git # git remote set-url origin git@local:kosm/myrepo.git

Setup in new repo:

touch README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin git@<Custom Host>:username/your-repository.git   # git remote add origin git@local:kosm/myrepo.git
git push -u origin master

You should not be asked for a username or password. If it works, your SSH key is correctly configured. Done
