My Autoscaled Instance Fails When Running "Git Clone" On A Private Repo. I

My autoscaled instance fails when running "git clone" on a private repo.

I do have the SSH key placed at /root/.ssh/id_rsa on the machine, and when I SSH into the machine and run sudo su; git clone <the repo> it succeeds.

Also, in the extra_vm_bash_script field: I added a whoami command which prints root , so it seems like the user being used to run the git clone during task execution is in fact root .

For context, here's the startup command that the autoscaler runs:

python -m clearml_agent --config-file /root/clearml.conf daemon --queue aws_4gpu_machines --docker python:3.9

Full log included...

Wow, it really does not want to show the output of those print statements in stdout. Here's the output of the task from the console after cloning it. Confirmed that the setup script and all code changes are present:

Remove this from your startup script:

#!/bin/bash 

there is no need that, it actually "markes out" the entire thing

Haha, that was a total gotcha for me. Yeah, a lot just wasn't even getting run due to the #!/bin/bash part.

Anyway, wow! I finally got the precious console logs you thought to find, here they are:

Well wow, I figured it out. You equiped me with a solid debugging tool AKA running bash commands within the docker container.

I had to pre-add GitHub and Bitbucket to known hosts by adding keyscan commands

configurations:
  extra_clearml_conf: ""
  extra_trains_conf: ""
  extra_vm_bash_script: |
    echo "fetching github key" && (aws ssm get-parameter --region us-west-2 --name /clearml/github_ssh_private_key --with-decryption --query Parameter.Value --output text > ~/.ssh/id_rsa && chmod 600 ~/.ssh/id_rsa) || echo "failed"
    source /clearml_agent_venv/bin/activate
    echo "fetching github key" && (aws ssm get-parameter --region us-west-2 --name /clearml/github_ssh_public_key --with-decryption --query Parameter.Value --output text > ~/.ssh/id_rsa.pub && chmod 600 ~/.ssh/id_rsa.pub) || echo "failed"
    source /clearml_agent_venv/bin/activate

    # I added these new lines:
    ssh-keyscan github.com >> ~/.ssh/known_hosts
    ssh-keyscan bitbucket.org >> ~/.ssh/known_hosts
