[docker/cli] Windows Docker image fails to run

GH-docker/cli#6347 • Mar 07, 2026

### ROOT CAUSE The error occurs because the Dockerfile used in the build process does not specify an ENTRYPOINT or CMD instruction. When the container is run, Docker attempts to execute an entrypoint script, which does not exist, leading to the "file not found" error. ### CODE FIX To resolve the issue, modify the Dockerfile to include an ENTRYPOINT instruction that specifies the command to execute when the container starts. For example, if you want the container to open a command prompt, add the following to the Dockerfile:
dockerfile
ENTRYPOINT ["cmd", "/K"]


If you have a specific script or command you want to run, replace the command accordingly.

---

### STEP-BY-STEP EXPLANATION:
1. **Identify the Missing Entry Point**: The error indicates Docker is trying to run a non-existent entrypoint script, likely due to the Dockerfile lacking an ENTRYPOINT or CMD instruction.
2. **Modify the Dockerfile**: Add an ENTRYPOINT instruction to specify the command to execute when the container starts.
3. **Rebuild the Image**: After updating the Dockerfile, rebuild the image to include the new entry point.

This ensures the container runs the specified command upon startup, preventing the error.
