lab-repo | my test lab setup for pxe booting and provisioning

We use a Gitlab Project in a team. Each developer has his own Kubernetes cluster in the cloud and an own branch within GitLab. We use GitLab-CI to automatically build new containers and deploy them to our Kubernetes clusters.

At the moment we have a .gitlab-ci.yml looks something like this:

I am trying to do a git clone of a private gitlab repo inside a shell script in Jenkinsfile and i have just been unable to find a way. I mean this is a simple git clone and i can't believe i have to come here to seek help with such simple task. It is unfortunate that gitlab support always comes with extra cost compared to github.

Another unfortunate thing is i have searched the whole internet and can't find a solution to my problem. I have the Gitlab plugin and also tried to use the gitlab api token, but there is no support for gitlab api token in jenkins..no way to use it with withcrdentials or any other thing

I have also tried regular withcredentials with username and password and that does not work either

also tried http and git repo url the http one says not found and the git or ssh one gives host key errors

what i have tried

I am new to gitlab and this is my first time using ssh. I could generate ssh key and add it into my account settings. I could clone the repo via ssh, I could checkout to my branch, but thing I still cannot do is push my change to the branch. Here is the step by step I generate the ssh key until I try to push it (by following instruction in here):

PS. I am using windows 10.

• on terminal (as admin), type: ssh-keygen -o -t rsa -b 4096 -C "myemail@example.com".
• Press Enter for default path of the ssh key
• Provide password
• Create config file in ~/.ssh/. Here is what I wrote in the config file:

Host ahostname Hostname myhostname.com User mygitlabusername Port port PreferredAuthentications publickey IdentityFile ~/.ssh/id_rsa

• copy the ssh key with this command: cat ~/.ssh/id_rsa.pub | clip
• Placed the ssh key into my account settings
• Then, run ssh -T git@myhostname.com, and here is the result:

The authenticity of host '[myhostname.com]:port ([123.456.789]:port)' can't be established. ECDSA key fingerprint is SHA256:xxxx. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '[myhostname.com]:port ([ipofmyshost]:port)' (ECDSA) to the list of known hosts. Enter passphrase for key 'C:~/.ssh/id_rsa': Welcome to GitLab, !

• Then I try to clone a repo: git clone ssh://git@myhostname.com/repo.git
• But, apparently, when cloning, it refer to another IP address. For example, let say ipofmyhost on the ssh -T git@myhostname.com is 123.456.789. Then, when I cloning, the IP is changed to 123.456.781 (sorry I am afraid I couldn't mention the real IP). So, here is what I got when try to cloning the repo:

Warning: Permanently added the ECDSA host key for IP address '[123.456.781]:port' to the list of known hosts. Enter passphrase for key '/c/.ssh/id_rsa':

• But, the clone done, then I checkout to my branch with git checkout mybranchname
• Now, I am in my branch. Make little change. Try to push, but here is the error I got:

git@myhostname.com: Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.

What I missed here? I found this question but sorry I do not understand what the accepted answer suggest me to do to solve this.

update

I've try to re-clone again, but before it, I delete all known_host. Then, do git clone again without testing with ssh -T git@myhostname.com to avoid creating new IP address. But, I still got the same error when push my branch even no new ip address added to the known_host.

I am using the Nix package manager on OSX Mojave.

My colleagues are using earlier versions of OSX. Not sure if that is the reason they are not encountering this problem.

I can't connect to a specific private gitlab repo that I explicitly have access to. I can clone it directly, but I can't build it when I am building the project that it is a part of.

This is the relevant excerpt from my default.nix file. I am told that fetchgitPrivate is deprecated. I have tried replacing it with fetchGit in this file, but it does not work.

I want to fetch the data from all the projects hosted by my GitLab instance. Now I know that GitLab displays 20 projects by default, so I need to set a bigger number of instances displayed per page:
