RubyMine 2023.3 Help

Connect and work with JetBrains Gateway

You can connect to a remote server using the SSH connection to develop, run and deploy your project.

You can also connect to development environments running on Gitpod, Google Cloud, GitHub Codespaces, Amazon CodeCatalyst, and Coder.

Prerequisites

Before you start developing on the remote machine, make sure you have the following:

  • Remote machine (a target for an IDE) meets the minimum recommended requirements that can be found in IDEs articles.

  • You have installed a compatible SSH server on the Linux platform.

  • The Linux platform has any recent Linux AMD64 distribution such as Ubuntu 16.04+, RHEL/Centos 7+, and so on. We recommend using machines with 2+ cores, 4GB+ of RAM, and 5GB+ of disk space.

  • You need to have the sftp subsystem enabled on the remote host. In the current implementation, we use it for the backend deployment.

JetBrains Gateway

JetBrains Gateway is a lightweight launcher that connects a remote server with your local machine, downloads necessary components on the backend, and opens your project in JetBrains Client.

You can use JetBrains Gateway as a standalone launcher or as an entry point from your IDE to connect to a remote server.

Launch JetBrains Gateway and connect to a remote server

  1. Download and install the JetBrains Gateway app.

    Alternatively, you can access JetBrains Gateway from the welcome screen of your IDE through the Remote Development option.

  2. Сlick New Connection under the SSH connection provider.

    Connect via SSH
  3. On the next page of the wizard, specify the SSH configuration through which you want to connect to a remote server.

    Connect via SSH

    Alternatively, click SSH configurations to open the SSH Configurations dialog and configure the SSH settings.

    In the SSH Configurations dialog, add the following information:

    SSH configurations
    • Host: specify the address of your remote server.

    • Port: specify the SSH port, which defaults to 22.

    • Local port: specify the outgoing port.

      For example, TCP 10.101.0.1:50705->13.49.137.87:22 (ESTABLISHED).

    • Username: specify the name of a user that will be used to connect to the remote server.

    • Authentication type: select one of the following authentication methods:

      • Password: to access the host with a password. To save the password in RubyMine, select the Save password checkbox.

      • Key pair (OpenSSH or PuTTY): to use SSH authentication with a key pair. To apply this authentication method, you must have a private key on the client machine and a public key on the remote server. RubyMine supports private keys that are generated with the OpenSSH utility.

        Specify the path to the file where your private key is stored and type the passphrase (if any) in the corresponding fields. To have RubyMine remember the passphrase, select the Save passphrase checkbox.

      • Parse config file ~/.ssh/config: select this option if you want JetBrains Gateway to use the .ssh/config file.

    • Test Connection: click this button to see whether the connection is established.

    • Connection Parameters: use this section to configure additional parameters for the connection.

    • HTTP/SOCKS Proxy: use this section to configure proxy settings. For more information, refer to Proxy settings.

    Click OK to save the changes and return to the Welcome to JetBrains Gateway dialog.

    Click Check Connection and Continue to check whether the connection is established.

  4. On the next page, specify the RubyMine version to download to the remote server. JetBrains Gateway displays a list of the IDEs versions that are available for downloading and the already installed ones.

    You can also use "Other options" for setting the alternative sources of IDE installers.

    The version of JetBrains Client downloaded to your local machine always matches the remote IDE version.

the IDE version

By default, the downloaded RubyMine is located in the following folder on the remote server: ~/.cache/JetBrains/RemoteDev/dist. However, you can change it and install RubyMine into a custom location with the following steps:

  1. Click Other options and select the Customize install path option.

  2. In the Install path field add the needed location for the installation.

Add the path to your project on the remote host.

Path to remote project

Click Upload IDE and Connect.

JetBrains Gateway downloads the IDE, and opens your remote project in JetBrains Client. The connection is shown in the JetBrains Gateway window, from which you can connect to other IDEs or disable the connection. This window is hidden to tray by default.

You can override the -Xmx VM options for the backend before you open your project.

Override -Xmx VM options

  1. Launch JetBrains Gateway.

  2. Follow the steps of the wizard. Click Check Connection and Continue.

  3. On the page that opens, under the IDE version field, click Installation options.

  4. From the drop-down list, select the Customize heap size.

  5. In the Maximum heap size field, override the default heap size as needed.

    Note that this field can only contain numeric values and cannot exceed the INT_MAX value.

  6. After you've done with your configurations, click Download IDE and Connect to start your project.

Open recent projects

  1. In the JetBrains Gateway wizard, select SSH from the options on the left.

  2. In the search field enter the name of your project to quickly navigate to it.

    Recent projects

    If you need to quickly access the terminal, click Open terminal.

Change the backend version

  • In the JetBrains Gateway wizard, click the More button next to the name of the recent project and choose the version of the backend with which you want to open your project.

    Change the backend version

    If you can't locate the necessary version in the list, click Select Different IDE and choose the desired IDE version in the IDE version field.

Stop the running instance

  1. In the JetBrains Gateway wizard, select SSH from the options on the left.

  2. When your remote session is active, the Running indicator is displayed next to the project.

    Click next to the project and select Stop IDE Backend to stop the remote session for that project.

    You can also select Remove from Recent Projects to remove the project listed on the page altogether.

Uninstall the backend IDE version

  1. In the JetBrains Gateway wizard, click the Show Options Menu icon against the name of the remote server and select Manage IDE Backends to open the list of installed IDE versions.

    Manage IDE
  2. In the window that opens, click the Close icon next to the backend IDE version you need to uninstall and click Yes to confirm the action.

Connect to a remote project on a manually launched remote IDE (Server-to-client flow)

If you already have RubyMine installed on your remote server, you can launch it manually and connect to the remote project started in that IDE. It works the same way as from JetBrains Gateway.

Use this approach if your company has a custom orchestration or in case your remote IDE starts automatically on its side.

The process can be described as follows:

  1. Start a backend project in the remote IDE.

  2. Select one of the connection links generated by the backend.

  3. Open the link on your local machine.

The main script to run a remote IDE is remote-dev-server.sh, located in the bin subdirectory of your unpacked IDE.

Connect to a remote IDE

  1. Ensure you have downloaded and installed JetBrains Gateway or you have an IDE with the JetBrains Gateway plugin on your local machine.

  2. Ensure you have connected to the remote machine with RubyMine via SSH.

  3. In the remote server's terminal, run the following command:

    remote-dev-server.sh run /path_to_project/ --ssh-link-host host_server_address --ssh-link-user remote_side_user --ssh-link-port ssh_connection_port

    Check the following example:

    If you don't pass the parameters, the script will use the default ones: 22 for port, system user's username, and host from the hostname command.

    ~/RM-213.5744.3/bin/remote-dev-server.sh run ~/RubymineProjects/SampleApp/ --ssh-link-host ec2-13-50-136-85.eu-north-1.compute.amazonaws.com

  4. If the project starts successfully, as an output, you should receive the following 3 links in the terminal:

    • Join link: tcp://127.0.0.1:5990...[ ]: contains the local address and port where the remote IDE is listening now.

      Example:

      tcp://127.0.0.1:5991#jt=71e779a1-070e-4fd3-a4e6-83c1f8cb65a5&p=IU&fp=A42F6041C2878D7A22339ECABF4A9C294F643BG05E91E3DFC06035E03DB71BF8&cb=222.4167.29&jb=17.0.4b469.53

      To use it, ensure the remote machine should be accessible by this local address. For example, for inside-Docker IDE with forwarded/open ports.

    • Http link: https://code-with-me.jetbrains.com/remoteDev...[ ]: contains information about your host-port-user, the IDE and its version.

      Example:

      https://code-with-me.jetbrains.com/remoteDev#idePath=%2Fhome%2Fubuntu%2F.cache%2FJetBrains%2FRemoteDev%2Fdist%2F3e4cd27bfbb95_ideaIU-2022.2.2&projectPath=%2Fhome%2Fubuntu%2Fdevelopment%2Fspring-petclinic&host=ec2-xx-xx-xxx-xx.eu-north-1.compute.amazonaws.com&port=22&user=ubuntu&type=ssh&deploy=false

      When opened in your local browser, it displays a welcome page and tries to call the local Gateway application with pre-filled connection settings values.

      If no JetBrains Gateway application is found on the local machine, you'll be able to download it from the welcome page.

    • Gateway link: jetbrains-gateway://connect#idePath... [ ]: also contains information about your host-port-user, IDE and its version.

      Example:

      jetbrains-gateway://connect#idePath=%2Fhome%2Fubuntu%2F.cache%2FJetBrains%2FRemoteDev%2Fdist%2F3e4cd27bfbb95_ideaIU-2022.2.2&projectPath=%2Fhome%2Fubuntu%2Fdevelopment%2Fspring-petclinic&host=ec2-xx-xx-xxx-xx.eu-north-1.compute.amazonaws.com&port=22&user=ubuntu&type=ssh&deploy=false

      When opened in your local browser, it launches the local JetBrains Gateway application directly without a welcome page.

  5. Copy the generated link and paste it into your local browser allowing it to Open JetBrains Gateway.

  6. All these links can be also opened in the already launched JetBrains Gateway.

    For this, on the JetBrains Gateway welcome screen, paste a link in the Connect to a Running IDE field, click Connect.

    RubyMine downloads the required version of JetBrains Client and opens the remote project inside it.

Registering previously installed remote IDE

Beginning with version 221.5481, you can manually register an existing backend IDE on the remote server and make it visible for Gateway.

To register the installed IDE and make it appear in the list of available builds, follow these steps:

  1. Connect to the remote server via SSH.

  2. Locate the folder with the unpacked IDE and open the bin directory.

  3. Use the command line to run the following command:

    remote-dev-server.sh registerBackendLocationForGateway

    Example:

    sh WebStorm-221.5591.52/bin/remote-dev-server.sh registerBackendLocationForGateway
