Hi All, I'M Having An Issue Running Clearml-Agent In Docker Mode. When Enqueuing A Task To The Docker Agent I Get The Following Error:

Hi all,
I'm having an issue running clearml-agent in docker mode. When enqueuing a task to the docker agent I get the following error:
error: could not write config file /root/.gitconfig: Device or resource busy

which if followed a git credentials error:
Using cached repository in "/root/.clearml/vcs-cache/not_sharing.git/my_secrets_here.git"
The fingerprint for the RSA key sent by the remote host is
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
error: Could not fetch origin
Repository cloning failed: Command '['git', 'fetch', '--all', '--recurse-submodules']' returned non-zero exit status 1.
clearml_agent: ERROR: Failed cloning repository.
1) Make sure you pushed the requested commit:
(repository='git@bitbucket.org:foo/bar.git', branch='master', commit_id='abcdefg', tag='', docker_cmd='foo/bar:latest -v /foo:/bar', entry_point='validation/drive_matcher_ros.py', working_dir='.')
2) Check if remote-worker has valid credentials [see worker configuration file]

I have SSH credentials defined and non-docker workers have no issues with git. Any idea how to solve this?

I did notice that clearml mounts the current user's .gitconfig to the docker's /root/.gitconfig which is what causes the write error. My question is, why does the docker even try to write to .gitconfig if it already exists?

I could not reproduce it... I think the issue might be that this folder is mounted to some host folder which causes a problem - can you check the docker command and see where it's mounted to?

it is /home This is how we share user dirs across multiple servers. I think this might be a permissions issue though. will try changing the permissions on .gitconfig and let you know if that helps

IS it /home ? I think it's only a subdir of home

Hi @<1523701235335565312:profile|HugeArcticwolf77> , is it possible you do not have root privileges inside the docker container?

these are the mounts I add:
-v /home/some_username/workspace/:/root/workspace -v /software:/software -v /images:/images -v /data:/data -v /processedData:/processedData -v /disk1:/disk1 -v /disk2:/disk2 -v /disk3:/disk3 -v /disk4:/disk4 -v /disk5:/disk5 -v /disk6:/disk6 -v /disk8:/disk8

None of these seem problematic to me. The only issue I can think of is that /home is an external mount on the host machine (outside of docker). Should I mount it somewhere?

@<1523701087100473344:profile|SuccessfulKoala55> any update on how to solve this?

yes.

I checked the base docker image I use and noticed that a $HOME/.gitconfig file already exists. would that be an issue given that the .gitconfig of the current user is mounted to that path once the clearml task is run?

And is the $HOME variable set correctly?

@<1523701087100473344:profile|SuccessfulKoala55> the docker user is root, but it does not have the "sudo" group if that's what you mean. Is that required?

EDIT: I just ran "sudo ls" and it returned with no issues so I guess I do have sudo permission :man-shrugging:
