However, I have 64 repositories that need to be mirrored across 2 GitLab groups. I can mirror them using a unique ssh key for every repo, but I would find it easier to have 1 ssh key for each group (so 2 of them in my case) so that it would be much easier to maintain. I did not find how to generate such a key for a group on GitLab. Herman Johnson / publickeys GitLab.
GitLab currently doesn't have built-in support for managing SSH keys in a buildenvironment (where the GitLab Runner runs).
The SSH keys can be useful when:
- You want to checkout internal submodules
- You want to download private packages using your package manager (e.g., Bundler)
- You want to deploy your application to your own server, or, for example, Heroku
- You want to execute SSH commands from the build environment to a remote server
- You want to rsync files from the build environment to a remote server

If anything of the above rings a bell, then you most likely need an SSH key.
Generate Ssh Key Putty
The most widely supported method is to inject an SSH key into your buildenvironment by extending your .gitlab-ci.yml
, and it's a solution which workswith any type of executor(Docker, shell, etc.).
How it works
- Create a new SSH key pair locally with
ssh-keygen
- Add the private key as a variable toyour project
- Run the
ssh-agent
during job to loadthe private key. - Copy the public key to the servers you want to have access to (usually in
~/.ssh/authorized_keys
) or add it as a deploy keyif you are accessing a private GitLab repository.
NOTE: Note:The private key will not be displayed in the job log, unless you enabledebug logging. You might also want tocheck the visibility of your pipelines.
SSH keys when using the Docker executor
When your CI/CD jobs run inside Docker containers (meaning the environment iscontained) and you want to deploy your code in a private server, you need a wayto access it. This is where an SSH key pair comes in handy.
You will first need to create an SSH key pair. For more information, followthe instructions to generate an SSH key.Do not add a passphrase to the SSH key, or the
before_script
willprompt for it.Create a new variable.As Key enter the name
SSH_PRIVATE_KEY
and in the Value field pastethe content of your private key that you created earlier.Modify your
.gitlab-ci.yml
with abefore_script
action. In the followingexample, a Debian based image is assumed. Edit to your needs:NOTE: Note:The
before_script
can be set globallyor per-job.Make sure the private server's SSH host keys are verified.
As a final step, add the public key from the one you created in the firststep to the services that you want to have an access to from within the buildenvironment. If you are accessing a private GitLab repository you need to addit as a deploy key.
That's it! You can now have access to private servers or repositories in yourbuild environment.
SSH keys when using the Shell executor
If you are using the Shell executor and not Docker, it is easier to set up anSSH key.
You can generate the SSH key from the machine that GitLab Runner is installedon, and use that key for all projects that are run on this machine.
First, log in to the server that runs your jobs.
Then, from the terminal, log in as the
gitlab-runner
user:Generate the SSH key pair as described in the instructions togenerate an SSH key.Do not add a passphrase to the SSH key, or the
before_script
willprompt for it.As a final step, add the public key from the one you created earlier to theservices that you want to have an access to from within the build environment.If you are accessing a private GitLab repository you need to add it as adeploy key.
Once done, try to log in to the remote server in order to accept the fingerprint:
For accessing repositories on GitLab.com, you would use git@gitlab.com
.
Verifying the SSH host keys
It is a good practice to check the private server's own public key to make sureyou are not being targeted by a man-in-the-middle attack. In case anythingsuspicious happens, you will notice it since the job would fail (the SSHconnection would fail if the public keys would not match).
Once a connection to a REST data source has been established, you can select data and load it into a Qlik Sense or QlikView app. You select data by selecting REST tables and fields in the data selection dialog. You can load data using either Add data or the Data load editor. The Qlik REST Connector supports the following paging options. Select Sequence ID as the Key generation strategy to use for creating primary and foreign keys in the data. The order of fields is the same in every record from Facebook, so Sequence ID can be used. It is the simplest and most efficient of the key generation options.
To find out the host keys of your server, run the ssh-keyscan
command from atrusted network (ideally, from the private server itself):
Create a new variable withSSH_KNOWN_HOSTS
as 'Key', and as a 'Value' add the output of ssh-keyscan
.
NOTE: Note:If you need to connect to multiple servers, all the server host keysneed to be collected in the Value of the variable, one key per line.

TIP: Tip:By using a variable instead of ssh-keyscan
directly inside.gitlab-ci.yml
, it has the benefit that you don't have to change .gitlab-ci.yml
if the host domain name changes for some reason. Also, the values are predefinedby you, meaning that if the host keys suddenly change, the CI/CD job will fail,and you'll know there's something wrong with the server or the network.
Now that the SSH_KNOWN_HOSTS
variable is created, in addition to thecontent of .gitlab-ci.yml
above, here's what more you need to add:

Description
The SSH stands for Secure Shell or Secure Socket Shell used for managing the networks, operating systems and configurations and also authenticates to the GitLab server without using username and password each time. You can set the SSH keys to provide a reliable connection between the computer and GitLab. Before generating ssh keygen, you need to have Git installed in your system.
Creating SSH Key
Step 1 − To create SSH key, open the command prompt and enter the command as shown below −
It will prompt for 'Enter file in which to save the key (//.ssh/id_rsa):', just type file name and press enter. Next a prompt to enter password shows 'Enter passphrase (empty for no passphrase):'. Enter some password and press enter. You will see the generated SSH key as shown in the below image −
Step 2 − Now login to your GitLab account and click on the Settings option.
Step 3 − To create SSH key, click on the SSH keys tab at left side of the menu.
Step 4 − Now go to C drive, you will see the file with .pub extension which was generated in the first step.
Step 5 − Next open the key.pub file, copy the SSH key and paste it in the highlighted Key box as shown in the below image −
Step 6 − Click on the Add Key button, to add SSH key to your GitLab. You will see the fingerprint (it is a short version of SSH key), title and created date as shown in the image below −
