How to solve the problem that Synology cannot use docker

In the process of using Synology, sometimes you may encounter situations where you cannot use docker. This brings a lot of trouble to users, making it impossible to use the powerful functions of docker when using Synology. This article will share some situations we encountered when we were unable to use docker and provide corresponding solutions.

1. The container cannot be started

If you find that the container cannot be started when using docker, the first thing to confirm is whether your Synology has installed docker. You can find the docker option in the control panel. If this option does not appear, you need to install docker first. If docker is already installed, you can try stopping, deleting, and re-creating the container to see if that solves the problem.

2. Unable to connect to the container

Sometimes, although the container has been started, it cannot be connected to the container. At this time, you can check the container's log first to see if there is any error message. If there is no error message, you can access it through the container's IP address or domain name. If you still cannot access, you can confirm whether the port is correct or whether there is a firewall blocking access.

3. The application in the container does not work properly

Sometimes, although the container has been successfully created and started, the application in it does not work properly. At this time, you can check the log first to see if there is any error message. If there is no error message, you can try restarting the container or reinstalling the application. If you still can't resolve the issue, you can try contacting the app developer to see if similar issue has occurred in the past.

4. Container cannot be updated

Sometimes, we want to update the application in the container, but the update fails. At this time, you can first check the log of the container to see if there is any error message. If there is no error message, you can try to stop and delete the container, re-create a new container, and select the latest image to create.

Summary

The inability to use docker is a very common problem, but it is not difficult to solve. First, you need to conduct an investigation to determine where the problem occurs, and then apply the corresponding solution. We hope this article can help users in need and make using Synology's docker smoother.
