Git configuration

Add global required configuration.

git config --global user.name <your gitlab login>
git config --global user.email <your gitlab email>

SSH key allows you to establish a secure connection between your docker container and GitLab.

Generate a SSH key in the docker command line (with a passphrase, please):

ssh-keygen -t rsa -b 2048 -C "<your gitlab email> gitlabciintroduction"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa): 
Created directory '/home/user/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/user/.ssh/id_rsa
Your public key has been saved in /home/user/.ssh/id_rsa.pub
The key fingerprint is:
SHA256: *******

Copy your public ssh key (cat /home/user/.ssh/id_rsa.pub to read it) into your GitLab profile SSH keys

Launch SSH agent to keep the SSH key addition alive:

echo "eval \"\$(ssh-agent -s)\"" >> /home/user/.bashrc
source /home/user/.bashrc
ssh-add
Enter passphrase for /home/user/.ssh/id_rsa: 
Identity added: /home/user/.ssh/id_rsa (<your gitlab email> gitlabciintroduction)

At this point, you will only have to relaunch ssh-add command if you exit and relaunch docker.

Branch creation

First, you will have to create a branch from the git repository on the INRIA GitLab as a branch of the main repository for the gitlabciintroduction project.

git clone git@gitlab.inria.fr:formations/integrationcontinue/gitlabciintroduction.git
Cloning into 'gitlabciintroduction'...
The authenticity of host 'gitlab.inria.fr (128.93.193.23)' can't be established.
ED25519 key fingerprint is SHA256:******.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'gitlab.inria.fr' (ED25519) to the list of known hosts.

remote: Counting objects: 100% (693/693), done.

By convention for the exercise, we will ask you to create a branch named <your gitlab login> to avoid duplicated branch name. The branch name you choose will be annotated <your branch name> in the exercise.

cd gitlabciintroduction
git checkout -b <your branch name>
   Switched to a new branch '<your branch name>'
git status
   On branch <your branch name>
   nothing to commit, working tree clean

We can now force the branch creation in order to trigger the default continuous integration script.

git push --set-upstream origin <your branch name>
   ...
   * [new branch]      <your branch name> -> <your branch name>
   Branch <your branch name> set up to track remote branch <your branch name> from origin.
