@Marvin I got this exception when running

prefect deploy

trying to deploy a

prefect.yaml

file that follows a gitlab master branch: "prefect.deployments.steps.core.StepExecutionError: Encountered error while running prefect_docker.deployments.steps.build_docker_image An exception occurred."

It seems you've encountered a common issue when deploying with Docker in Prefect. Here are a few potential reasons and fixes based on the gathered information: 1. Docker Not Running: - Ensure that Docker is running on your machine. The error may arise if Docker is not active or properly installed.

sh
    sudo systemctl start docker

2. Virtual Environment Issues: - Ensure the necessary packages are installed within your virtual environment. Prefect might attempt to auto-install packages with

requires

, but manual installation sometimes avoids issues.

sh
    pip install prefect-docker>=0.3.0

3. Manifest Not Found: - If you encounter an issue with the Docker image tag, ensure the tag exists or is correctly specified.

sh
    # Example Docker command to pull the correct image
    docker pull prefecthq/prefect:v2.14.6-python3.11

- Alternatively, adjust your

prefect.yaml

to use a tag that exists. 4. Windows-Specific Issues: - Windows users might face specific issues with certain commands. Ensure your

prefect.yaml

and environment are correctly configured for Windows. 5. Repository Configuration: - Ensure your GitLab repository is accessible and properly configured in your

prefect.yaml

. Here are some useful debugging tips and links: - For Docker issues, refer to Prefect's Docker Integration Guide. - For command usage and flags, check Prefect Deployment Guide. Would you like more details on any specific aspect? Seems like asking me for help was inevitable.
