Failed to start docker container after reboot

If a Docker container fails to start after a reboot, there are several things you can try to troubleshoot the issue:

• Check the container's status: Use the docker ps -a command to view the status of all containers, including stopped containers. If the container is not running, it will be listed as "Exited" with a non-zero status code. This can indicate that there was an error during startup.

• Check the container logs: Use the docker logs [container-name] command to view the container's logs. This can help you identify any errors or issues that the container encountered during startup.

• Inspect the container: Use the docker inspect [container-name] command to view detailed information about the container's configuration. This can help you identify any misconfigurations that might be causing the container to fail to start.

• Check the host's resources: Make sure the host machine has enough resources available, such as CPU and memory, to start the container. If the host machine is running low on resources, the container may fail to start.

• Check the host's firewall: Make sure that the host's firewall is not blocking the container's network ports. If the firewall is blocking the ports, the container may fail to start.

• Restart the Docker daemon: Restart the Docker daemon using the sudo service docker restart command. This can help to resolve any issues with the daemon that might be causing the container to fail to start.

• Try starting the container with docker start command: If the container was running before the reboot, use docker start [container-name] command to start the container again.

• Try removing the container and creating a new one: If all the above steps fail to start the container, you can remove the container and create a new one with docker rm [container-name] and docker run commands respectively.

These are ways to troubleshoot a failed to start Docker container after reboot, and it's worth trying all of them to see which one resolves the issue.
