Resolving 'no configuration file provided: not found' in Docker Compose
Troubleshoot and fix the common Docker Compose error 'no configuration file provided: not found', especially in WSL2 environments.
Encountering the error no configuration file provided: not found when running Docker Compose can be frustrating. This error typically indicates that Docker Compose cannot locate its expected configuration file, usually docker-compose.yml or docker-compose.yaml. This article will explore the common causes of this issue and provide actionable solutions, with a particular focus on environments using Windows Subsystem for Linux (WSL2) with Docker Desktop.
Understanding the Docker Compose Error
Docker Compose is a tool for defining and running multi-container Docker applications. It uses a YAML file to configure application's services, networks, and volumes. When you execute a Docker Compose command (e.g., docker compose up), it looks for this configuration file in the current directory by default. If it can't find it, or if it's named incorrectly, you'll see the 'not found' error.

Common Causes and Solutions
Several factors can lead to this error. Addressing them systematically will help resolve the issue quickly.
Troubleshooting flow for Docker Compose configuration file errors.
.yml vs. .yaml) are crucial, especially in Linux/WSL environments.1. Step 1
Verify Current Directory: Ensure you are running the docker compose command from the directory where your docker-compose.yml file is located. Use ls (Linux/WSL) or dir (Windows CMD/PowerShell) to list files in the current directory.
2. Step 2
Check Filename and Extension: The default filenames are docker-compose.yml or docker-compose.yaml. Make sure your file matches one of these exactly. Pay attention to hyphens and case.
3. Step 3
Specify Configuration File Path: If your file is not in the current directory or has a non-standard name, you can explicitly tell Docker Compose where to find it using the -f or --file flag. For example: docker compose -f /path/to/your/custom_compose.yml up.
4. Step 4
Check File Permissions: Ensure that the user running the Docker Compose command has read permissions for the docker-compose.yml file. In Linux/WSL, you can use chmod 644 docker-compose.yml to grant read/write for owner and read for others.
5. Step 5
Ensure Docker Desktop is Running (for Windows/macOS): Docker Compose relies on the Docker daemon. If Docker Desktop isn't running, Docker Compose won't function correctly. Verify that Docker Desktop is active and healthy.
Specific Considerations for WSL2 and Docker Desktop
When using Docker Desktop with WSL2, the integration is generally seamless. However, sometimes pathing or file system nuances can cause issues.
Docker Desktop, when configured to use the WSL2 backend, makes the Docker daemon available within your WSL distributions. This means you should run Docker Compose commands directly from your WSL terminal. The key is ensuring that your docker-compose.yml file is accessible within the WSL filesystem context where you are executing the command.
docker-compose.yml files on Windows drives (e.g., C:\) and accessing them from WSL (/mnt/c/). While technically possible, it can sometimes lead to permission issues or slower I/O. It's best practice to keep your project files directly within your WSL distribution's filesystem (e.g., in ~/myproject).# Navigate to your project directory within WSL
cd ~/myproject/my-docker-app
# Verify the file is present
ls -l docker-compose.yml
# Run Docker Compose
docker compose up -d
Demonstrates correct directory navigation and command execution within WSL2.
Troubleshooting Steps Recap
To summarize, when you encounter the 'no configuration file provided: not found' error, follow these steps:
1. Step 1
Navigate to the correct directory: Use cd to go to the directory containing docker-compose.yml.
2. Step 2
List files: Use ls to confirm docker-compose.yml (or .yaml) is present and correctly named.
3. Step 3
Check permissions: Ensure the file has read permissions for your user.
4. Step 4
Explicitly specify file: If needed, use docker compose -f path/to/file.yml up.
5. Step 5
Verify Docker daemon: Ensure Docker Desktop (or your Docker daemon) is running.
