Docker Engine Docker: Error response from daemon: failed to remove container

The container is still running or being used by another process.

Understanding Docker Engine

Docker Engine is a containerization technology that allows developers to package applications and their dependencies into a standardized unit called a container. This tool is essential for creating, deploying, and managing containers in a consistent environment, ensuring that applications run seamlessly across different systems.

Identifying the Symptom

When working with Docker, you might encounter the error message: Docker: Error response from daemon: failed to remove container. This message indicates that there is an issue preventing the removal of a container.

What You Observe

Typically, this error occurs when you attempt to remove a container using the docker rm command, and the operation fails. The error message suggests that the container cannot be removed, which can be frustrating when trying to clean up your environment.

Exploring the Issue

The error message Docker: Error response from daemon: failed to remove container usually means that the container is still running or is being used by another process. Docker requires that a container be stopped before it can be removed. If the container is in use, Docker will not allow its removal to prevent potential data loss or corruption.

Common Causes

  • The container is still running.
  • Another process is using the container.

Steps to Resolve the Issue

To resolve this issue, you need to ensure that the container is stopped and not in use. Follow these steps:

Step 1: Stop the Container

First, ensure that the container is not running. Use the following command to stop the container:

docker stop

Replace <container_id_or_name> with the actual ID or name of the container you wish to stop.

Step 2: Verify the Container is Stopped

Check the status of the container to confirm it is stopped:

docker ps -a

This command lists all containers, including those that are stopped. Ensure the container you want to remove is not listed as running.

Step 3: Remove the Container

Once the container is stopped, you can remove it using:

docker rm

If the container is still not removable, ensure no other processes are using it.
