Docker Service Status

Use a remote terminal to log in to the server where the instruction stream cloud phone is deployed as the instruction stream cloud phone O&M user (for example, root).
Run the following command to query the Docker service status:
```
systemctl status docker
```
If the value of Active is active (running), the Docker service state is normal. Otherwise, the service state is abnormal.
If the service status is abnormal, run the following command to check the cause of the Docker service startup failure.
```
dockerd --debug
```
If the fault persists, restart the Docker service (for details, see 4) or contact Huawei technical support.
Restart the Docker service. After the restart, check whether the service status is active (running).
```
systemctl daemon-reload
systemctl restart docker
```
- systemctl daemon-reload: Start the Docker daemon process.
- systemctl restart docker: Restart the Docker service.
