Connect to Docker daemon with

Select the method for connecting to the Docker API.

  • Docker for Windows: The recommended option when using Docker Desktop for Windows.

  • Docker for Mac: The recommended option when using Docker Desktop for Mac.

  • Unix socket: This is the recommended connection option for Linux.

    note

    If you get permission denied errors, add the current user to the docker group on the machine, log out, and then log back in. The docker group grants privileges equivalent to the root user. For details on how this impacts security in your system, see Docker Daemon Attack Surface.

  • Docker Machine: If you are using Docker Toolbox for Windows or macOS, this is the recommended option for connecting to the Docker API. If the Connection successful message doesn't appear, check your Docker Machine executable setting on the Docker | Tools page.

  • TCP socket: This method should work for any Docker version and operating system. Use this method only for special cases and custom configurations. In most cases, you should use one of the recommended methods that don't require manual configuration.

    • If you are using Docker Desktop and want to connect through the TCP socket, enable the Expose daemon on tcp://localhost:2375 without TLS option in the General section of your Docker settings. Then set Engine API URL to tcp://localhost:2375.

      If the option is disabled, then you can connect through a named pipe: npipe:////./pipe/docker_engine.

      Leave the Certificates folder field empty.

    • If you are using Docker Toolbox, set Engine API URL to https://192.168.99.100:2376 and Certificates folder to %HOMEPATH%\.docker\machine\machines\default.

    note

    Since the Certificates folder field specifies any folder with certificates, this field corresponds to the DOCKER_CERT_PATH environment variable. For more information, see Client modes in the Docker documentation.

  • SSH: Connect to a remote Docker daemon via an existing SSH configuration or create a new one.

  • Minikube: If you are running minikube, select this option to automatically detect and connect to the minikube's Docker Engine environment.

In the table below, specify the mappings for folders that can be shared between the host and the container volumes.

Use the Edit button to edit an existing mapping, or the Add button to create a new one.

  • Virtual machine path: The path to the directory in the Docker virtual machine's file system.

  • Local path: The path to the local folder that you want to bind to the corresponding directory in the virtual machine.
