Create an Internal GIT Server

Create a Git server

First set up a CT (Ubuntu 22.04) with standard settings, yes 512 RAM is plenty and 8G should be ok for your projects. Start your CT and update it to latest.

apt update && apt dist-upgrade -y

In the console or an ssh window, do the following:

Install Git

apt install git

Create a Git User

adduser git

Create a Repository

mkdir /usr/local/git

Change the ownership of the directory to the git user

chown git:git /usr/local/git

Switch to the git user

su -l git

Initialize a new bare repository

git init –bare mystuff.git

Configure SSH access for the git user

mkdir .ssh && chmod 700 .ssh
touch .ssh/authorized_keys && chmod 600 .ssh/authorized_keys

Add SSH public keys to the authorized_keys file

Create a key <my new key> for use with this git and cat <my new key>.

Use ED25519 keys, they are more secure and shorter.

nano  ~/.ssh/authorized_keys

Clone the repository to the server

git clone git@<server>:/usr/local/git/mystuff.git

Start using the Internal Git Server

Copy your stuff to the internal Git Server for all your users to use.

git clone git@<server>:/usr/local/git/mystuff.git

Generate an SSH key pair

ssh-keygen -t ed25519 -C “[email protected]” -f ~/.ssh/mykeys/git_key

• -C “[email protected]”
  A comment is appended to the end of the public key file to easily identify it.
  Normally, an email address is used for the comment, but use whatever works best for you.
• -f ~/.ssh/mykeys/git_key
  Filename of the private key file, if you choose not to use the default name.
  Two files are created, the private key git_key and the corresponding public key git_key.pub is generated in the same directory. The directory must exist.

Print out the public key and copy it.

cat ~/.ssh/mykeys/git_key.pub
