I'm trying to use the Azure DevOps pipeline. The main repository the pipeline is supposed to run on is cloned just fine, except that I can't get to clone it's submodules. The submodules are added using SSH URLs because that's what is set up in my computer.
The cloning process fails with:
Please make sure you have the correct access rights
and the repository exists.
fatal: clone of '[email protected]:v3/<rest_of_link>' into submodule path '/home/vsts/work/1/s/Modules' failed
Failed to clone 'Modules' a second time, aborting
So, since I'm using SSH, I've gone ahead and created a pair of RSA keys and I'm using Azure's own task to install it, as shown below:
- task: InstallSSHKey@0
inputs:
knownHostsEntry: '<entry>'
sshPublicKey: '<public_key>'
sshKeySecureFile: 'id_rsa'
It succeeds with the following output:
/usr/bin/ssh-agent
SSH_AUTH_SOCK=/tmp/ssh-XXXXXXFGcDdd/agent.1614; export SSH_AUTH_SOCK;
SSH_AGENT_PID=1615; export SSH_AGENT_PID;
echo Agent pid 1615;
/usr/bin/ssh-add -L
The agent has no identities.
/usr/bin/ssh-add /home/vsts/work/_temp/id_rsa
Identity added: /home/vsts/work/_temp/id_rsa (jose@42we-desktop)
/usr/bin/ssh-add
Finishing: InstallSSHKey
Great, right? Except that if I try to initialize the submodules with:
GIT_SSH_COMMAND="ssh -v" git submodule update --init --recursive
It still fails.
By looking at the extra information supplied through the usage of the -v flag, I can see that it initially accepts the key, and even says Authenticated to ssh.dev.azure.com, only to then fail after git-upload-pack

Why does it fail?? It really doesn't make sense in my head, and the output I can see if I clone in my computer (running Fedora) is the same until the "git-upload-pack".
SOLVED SOLVED SOLVED SOLVED
Turns out I needed to add the generated SSH key to my account as well. I didn't think this made sense at first because the authentication should happen between azure machines itself... either way. It's done and it works!
