Willingness to contribute

The MLflow Community encourages bug fix contributions. Would you or another member of your organization be willing to contribute a fix for this bug to the MLflow code base?

• Yes. I can contribute a fix for this bug independently.
• Yes. I would be willing to contribute a fix for this bug with guidance from the MLflow community.
• No. I cannot contribute a bug fix at this time.

System information

• Have I written custom code (as opposed to using a stock example script provided in MLflow): No
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows 10
• MLflow installed from (source or binary): pip
• MLflow version (run mlflow --version): 1.18.0
• Python version: 3.7.10
• npm version, if running the dev UI:
• Exact command to reproduce: mlflow run examples/docker -P alpha=0.5 or mlflow run examples/docker -P alpha=0.5 --backend kubernetes --backend-config kubernetes_config.json

Describe the problem

Describe the problem clearly here. Include descriptions of the expected behavior and the actual behavior.

I work on my company laptop which may be the reason this bug happened. I have been trying to use MLflow projects in Docker environment or with Kubernetes as backend. However when I try to run it, it produces PermissionError. The error is produced whenever MLflow tries to remove the temp directory it created in _create_docker_build_ctx function. this is the exact line that produces the error

mlflow/mlflow/projects/docker.py

Line 117 in 221fedc

shutil.rmtree(directory)

Code to reproduce issue

Provide a reproducible test case that is the bare minimum necessary to generate the problem.

Clone MLflow repository and try to run the docker container with the following commands:

• mlflow run examples/docker -P alpha=0.5
• mlflow run examples/docker -P alpha=0.5 --backend kubernetes --backend-config kubernetes_config.json

Other info / logs

Include any logs or source code that would be helpful to diagnose the problem. If including tracebacks, please include the full traceback. Large logs and files should be attached.
