[JENKINS-58845] Jenkins Docker Desktop git ssh temporary credentials file bad permissions

Hi,

i have the following error message when trying to access my gitlab server via ssh from my jenkins:

 

stdout: 

stderr: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@ WARNING: UNPROTECTED PRIVATE KEY FILE!  @

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Permissions 0555 for '/var/jenkins_home/caches/git-0aa16db65c903d3ced737f801b217112@​tmp/jenkins-gitclient-ssh2425211278542515051.key' are too open.

It is required that your private key files are NOT accessible by others.

This private key will be ignored.

Load key "/var/jenkins_home/caches/git-0aa16db65c903d3ced737f801b217112@​tmp/jenkins-gitclient-ssh2425211278542515051.key": bad permissions

Permission denied (publickey).

fatal: Could not read from remote repository.

My environment is the following:

Host System: Windows 10

Docker Desktop 2.1.0 with Linux based containers

Jenkins Docker Container: jenkins/jenkins and jenkins/jenkins:lts

 

I've a similar setup running with a linux for Docker and there isn't the same problem.

For testing purposes i've installed the latest beta version (3.0.0-beta10) of the "git client plugin" as suggestet in the comment of https://issues.jenkins-ci.org/browse/JENKINS-53933. But this didn't solve the problem.

I'm not sure if the credentials-binding-plugin is the right component for this.

It seems that other people have the same problem. e.g. The comment at the bottom of https://wiki.jenkins.io/display/JENKINS/SSH+Credentials+Plugin .
