detected dubious ownership in repository at '/tmp/build/get'

[NullOranje]

Describe the bug

When attempting to get a git-resource, we receive the git error detected dubious ownership instead of pulling the source code.

Reproduction steps

1. Deploy concourse quickstart using provided docker-compose.yml (using Concourse 7.9.1)

2. Deploy a simple pipeline:

resources:
  - name: git-repo
    type: git
    icon: git
    source:
      uri: http://gitea:3000/org1/myproject
      username: ((gitea.username))
      password: ((gitea.password))
jobs:
- name: validate-repo
  plan:
    - get: git-repo
      trigger: false
    - task: list-files
      config:
        inputs:
          - name: git-repo
        platform: linux
        image_resource:
          type: registry-image
          source:
            repository: busybox
        run:
          path: tree

3. Unpause the pipeline
4. Receive the following error:

selected worker: 31354ca107d3
Cloning into '/tmp/build/get'...
fatal: detected dubious ownership in repository at '/tmp/build/get'
To add an exception for this directory, call:

	git config --global --add safe.directory /tmp/build/get

...

Expected behavior

Expect the git repo to be available for pipeline consumption,

This seems to be an issue with houdini/Docker for Mac. Running this on a Kubernetes cluster on the same Docker for Mac instance with containerd does not encounter this issue.

Alternative workaround if you work on a local concourse instance:

git_config:
- name: safe.directory
  value: /tmp/build/get

git_config:

This has worked for me on the get step but having the same issue now in the put step as

Identity added: /tmp/git-resource-private-key (/tmp/git-resource-private-key)
fatal: detected dubious ownership in repository at '/tmp/build/put/repo'
To add an exception for this directory, call:

	git config --global --add safe.directory /tmp/build/put/repo

    git_config:
    - name: safe.directory
      value: '*'

Solved the issues for me

Question, where do you writ that, because, i tried on the task, on the resource section, and not be able to works

Even I try this. but still failing

resources:
- name: concourse-examples
  type: git
  icon: github
  check_every: 30m
  source:
    uri: https://github.com/concourse/examples
    branch: master
    safe_directory: /tmp/build/*

Like this

resources:
- name: repo
  type: git
  source:
    uri: https://github.com/foo.git
    # this is to avoid git permission error.
    git_config:
    - name: safe.directory
      value: '*'
