How to troubleshoot when accessing the container service fails after starting Docker?

There are various reasons why accessing the Docker container service may fail after startup. Here are some common solutions:

1. Check if the container is running: You can use the command “docker ps” to check the status of the container. If the container is stopped, you can use the command “docker start ” to start the container.
2. Check if the container is bound to the correct port: If the container is providing a service and needs to be accessed through a specific port, make sure the container’s port bindings are set correctly. You can use the ‘docker ps’ command to view the container’s port mappings.
3. Check container network settings: If the container is using custom network settings, verify that the network configuration is correct. You can use the “docker network ls” command to view available networks and the “docker inspect ” command to view the container’s network configuration information.
4. Check firewall settings: If the container service is being blocked in the firewall, you can try disabling or modifying the firewall rules. The specific actions will depend on the operating system and firewall program being used.
5. Check container logs: Ensure to examine the log output of containers by utilizing the command “docker logs “. These logs may contain relevant information regarding any startup failures or service errors.
6. Check the host network connection: If the container is running on a remote host, make sure the host’s network connection is working properly by testing the network connectivity of the host using ping or telnet commands.

If none of the previously mentioned methods are able to resolve the issue, further investigate the configuration and environment of the container, as well as any related error messages. Based on the specific error information, more detailed troubleshooting and solutions can be explored.
