Docker Engine is a containerization technology that allows developers to package applications and their dependencies into containers. These containers can run on any system that has Docker installed, ensuring consistency across different environments. Docker Engine is widely used for its efficiency in managing application deployments and scaling.
When working with Docker, you might encounter the error message: Docker: Error response from daemon: container is not running. This error typically occurs when you attempt to perform an operation on a container that is not currently running.
This error message indicates that the Docker daemon is unable to execute the requested operation because the target container is in a stopped state. Containers can stop due to various reasons, such as manual intervention, application errors, or system reboots. Understanding the state of your containers is crucial for effective Docker management.
docker stop.To resolve this issue, you need to start the stopped container. Follow these steps:
First, identify the status of your containers by listing them. Use the following command:
docker ps -a
This command will display all containers, including those that are stopped. Look for the container ID or name of the container you wish to start.
Once you have identified the container, start it using the following command:
docker start <container_id_or_name>
Replace <container_id_or_name> with the actual ID or name of your container.
After starting the container, verify that it is running by executing:
docker ps
This command lists all currently running containers. Ensure your container appears in this list.
For more information on managing Docker containers, refer to the official Docker documentation on container management. Additionally, you can explore Docker's automatic restart policies to ensure your containers restart automatically after a system reboot.
