Docker Engine is a containerization technology that allows developers to automate the deployment of applications inside lightweight, portable containers. It is widely used for its efficiency in creating consistent development and production environments. Docker Engine manages the lifecycle of containers, including building, running, and orchestrating them.
When working with Docker, you might encounter the error message: Docker: Error response from daemon: failed to create endpoint. This error typically arises when there is an issue with network configuration or conflicts within Docker's networking setup.
Upon attempting to start a Docker container, the process fails, and the error message is displayed. This prevents the container from being accessible or functional as intended.
The error failed to create endpoint indicates that Docker is unable to establish a network endpoint for the container. This can occur due to several reasons, such as:
Docker uses a network bridge to connect containers to the host network. If there are overlapping IP ranges or misconfigured network settings, Docker may fail to create the necessary network endpoint.
First, check the existing Docker networks to identify any conflicts:
docker network ls
Review the output for overlapping subnets or duplicate network names.
Inspect the specific network configuration that might be causing the issue:
docker network inspect <network_name>
Look for any anomalies or misconfigurations in the network settings.
If you identify a problematic network, remove it and recreate it with the correct settings:
docker network rm <network_name>
docker network create --subnet=<correct_subnet> <network_name>
After making changes, restart the Docker service to apply the new network configurations:
sudo systemctl restart docker
