Howto install git, generate a ssh-key, do the ssh-config and create a git repo.

Install git

On debian/ubuntu based system it rather simple to install git:

apt-get install git

Generate ssh-key

CLI way to generate a key for gitlab. I use a separate keys for each host/server. It makes it easier to delete a key after projects are done. In this example a “fabacademy-gitlab” key pair is created:

So first go your .ssh directory, located in HOME:

cd ~/.ssh

ssh-keygen -t rsa -b 4096 -C "your@mailaddr.ess"

Runnig the command generates output like this:

Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa): /home/user/.ssh/fabacademy-gitlab
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/user/.ssh/fabacademy-gitlab.
Your public key has been saved in /home/user/.ssh/
The key fingerprint is:
SHA256:******************************************* your@mailaddr.ess
The key's randomart image is:
+---[RSA 4096]----+
|* O^ OO  . o     |
|  + X+@ o   O    |
|.  %o      S    .|
|  .  O           |
|  =  *  S  o     |
|     O  . *      |
|         . . .   |
| F o             |
|              ...|


edit you ssh config file. It’s located mostly in ~/.ssh/config

At the end of the file insert lines like these:

Host gitlab
User git
Identityfile ~/.ssh/fabacademy-gitlab
IdentitiesOnly yes

Because this config you can now change the user & hostname parts of the git commands. Change “” for “gitlab”

Git global setup

git config --global "your name"
git config --global "your@mailaddr.ess"

Create a new repository

git clone gitlab:academany/fabacademy/2018/labs/fablabamsterdam/students/your-name.git
cd your-name
git add
git commit -m "add README"
git push -u origin master

Existing folder

cd existing_folder
git init
git remote add origin gitlab:academany/fabacademy/2018/labs/fablabamsterdam/students/your-name.git
git add .
git commit -m "Initial commit"
git push -u origin master

Existing Git repository

cd existing_repo
git remote rename origin old-origin
git remote add origin gitlab:academany/fabacademy/2018/labs/fablabamsterdam/students/your-name.git
git push -u origin --all
git push -u origin --tags

Adding and commiting changes to gitlab

So from now on you work with the local files. Once you are satisfied with the changes and additions to the site, it’s time to update the repository on gitlab. First you go to the root directory of the project.

cd ~/documentation-theme-jekyll

git pull (for getting the last commits from gitlab, actually it's a command that you have to run before you start editing)

git add . (for all files you haven't added to the repository) 

git commit . (now you can write a comment about the changes or additions)

git push (pushes the  changes or additions to gitlab)
