Install WKT UI

  1. Download the latest WebLogic Kubernetes Toolkit UI (WKT UI) application installers from the GitHub Releases section of this repository.
  2. Simply run the appropriate installer for your operating system.

Each release has many assets, some of which are needed for the application’s auto-update functionality and are not intended to be used for installing the application. The following table lists the installer file names and their purpose.

Installer File Name Purpose
WebLogic-Kubernetes-Toolkit-UI-1.4.1-arm64.dmg macOS Apple Silicon (M1) installer.
WebLogic-Kubernetes-Toolkit-UI-1.4.1.AppImage Linux AppImage package of the application.
WebLogic-Kubernetes-Toolkit-UI-1.4.1.dmg macOS Intel (x86-64) installer.
WebLogic-Kubernetes-Toolkit-UI-Setup-1.4.1.exe Windows installer.
wktui-1.4.1.x86_64.rpm Linux RPM package installer.
wktui_1.4.1_amd64.deb Linux DEB package installer.

The Linux AppImage package is not an installer. It is a portable packaging of the application that can run directly without installation on a compatible Linux machine. For more information, see

NOTE: On Linux, to get all the dependencies and have them installed in the correct order, you need to use the package manager to install the rpm or deb file. First, be sure to review the Linux prerequisites here.

  • For RPM-based systems, use either yum or dnf; for example:

    yum update
    sudo yum -y localinstall wktui_1.0.0_amd64.rpm
  • For Debian-based systems, use:

    sudo apt update
    sudo apt upgrade
    sudo apt install ./wktui_1.0.0_amd64.deb

If the installation is on a server machine, you should logout from the current terminal session and use X11 forwarding mechanism or any remote desktop application to the remote terminal for launching the WKT UI application.

Alternatively, you can download the AppImage file, copy it to your local file system, then either:

  • Open a terminal, navigate to the directory where the file exists, and make it executable; for example:

    chmod u+x <AppImage Name>

  • Use your file manager, right click on the file, edit the properties, and change the permissions to make it executable.

If you download and run the AppImage file, you get the added benefits of 1.) Not requiring an installation or root access and 2.) Being able to participate in the auto-update functionality, like macOS and Windows.

Helpful Hints

  • When launching the WKT UI application, if you see this:

    libGL error: No matching fbConfigs or visuals found
    libGL error: failed to load driver: swrast

    This is harmless and can be removed by setting the environment variable:


  • If you are storing credentials in the OS native store, and you see this failure message:

    Error occurred in handler for 'save-project': Error: Failed to save credential for image.
    imageRegistryPushUser: Error: No such interface "org.freedesktop.Secret.Collection" on object at path /
        at /tmp/.mount_WebLogpIPFto/resources/app.asar/app/js/credentialManager.js:92:32

    You can solve it by running this command (only once) before launching the WKT UI application:

    dbus-update-activation-environment --systemd DBUS_SESSION_BUS_ADDRESS DISPLAY XAUTHORITY

Application Startup

Application startup detects Internet connectivity to GitHub. If it fails to connect, a Network Configuration dialog appears in which you can set or modify your proxy settings, test your changes, and then restart the application.

Launching the application displays a thorough “Introduction” to the WKT UI. Step through it or dismiss it; you can peruse it at any time using Help > Show Introduction.

Version Updates

Upon application startup, if a more recent version exists, an Application Update dialog appears with these choices:

  • Install Now
  • Install on Exit
    • Downloads the application and installs it after you exit.
    • Not available on macOS.
  • Ignore Update

At any time, you can check for application updates using Help > Check for WKT UI Updates.

For updates to in-application versions of WKT Tools (WebLogic Deploy Tooling and WebLogic Image Tool), select Help > Check for WKT Tool Updates.
