Docker

Name

The name of the configuration.

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.

  macOS

  Linux

  Minikube

  • 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.

  • If you are using Docker Desktop, set Engine API URL to unix:///var/run/docker.sock and 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 ~/.docker/.

  Engine API URL: unix:///var/run/docker.sock

  Certificates folder: leave empty

  You can manually configure the connection to the minikube's Docker Engine environment if the Minikube option fails to automatically detect it.

  Run the minikube docker-env command to get the necessary connection information and set the following:

  • Engine API URL: the value of DOCKER_HOST (with https as the protocol instead of tcp)

  • Certificates folder: the value of DOCKER_CERT_PATH

  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.

Path mappings

For Windows and macOS: Specify the mappings for folders that can be shared between the host and the container volumes.

Use to edit an existing mapping, or to create a new one.

• Local path: The path to the local folder that you want to make available for volume bindings.

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