Hi,

These error lines indicate that a DockerException was raised during the execution of a Python script. This exception occurred in the context of initializing a Docker client in your Python application, specifically when trying to fetch the server's API version. Here's a breakdown of the key elements of the error:

client = docker.from_env(): This line attempts to create an instance of the Docker client based on the system's environment configuration. It's generally the standard way to connect to the Docker API using the Python docker library.

self.api = APIClient(*args, **kwargs) and self._version = self._retrieve_server_version(): These lines indicate that the Docker client is trying to initialize the API client and retrieve the Docker server's API version. This is necessary to ensure compatibility of API calls between the client and the server.

raise DockerException(...): This shows that, when trying to fetch the server's API version, a DockerException is raised. This typically occurs when there's a problem communicating with the Docker daemon. The specific error indicated by Error while fetching server API version suggests that the Python script was unable to retrieve the server's API version, which is essential for communication between the client and the server.

Possible reasons for this error could include:

Docker Daemon not started or installed: Ensure that the Docker service is running on your system.
Permission issues: The Python process might not have the necessary permissions to communicate with the Docker daemon.
Network configuration: There could be network configuration issues preventing communication with the Docker daemon.
Incompatible API version: The server's Docker API version may not be compatible with the client library used.
To resolve this error, you should check the Docker service's status on your system, review the Python process's permissions, and ensure that your environment is properly configured to allow communication with Docker.
