CodePudding user response：

May be you started the Docker after your PyCharm has been started. Simply right click to the Docker expandable item and choose Disconnect and then right click again and choose Connect to restart the connection.

You can follow the official instructions. Particularly this part:

Configure the Docker daemon connection settings:

Press Ctrl Alt S to open the IDE settings and select Build, Execution, Deployment | Docker.

Click to add a Docker configuration and specify how to connect to the Docker daemon.

The connection settings depend on your Docker version and operating system. For more information, see Docker configuration.

The Connection successful message should appear at the bottom of the dialog.
