    sudo dnf config-manager --add-repo https://downloads.k8slens.dev/rpm/lens.repo

    If DNF is not available, use the YUM package manager:

    sudo yum-config-manager --add-repo https://downloads.k8slens.dev/rpm/lens.repo

  2. Install or update Lens Desktop using DNF:

    sudo dnf install lens

    If DNF is not available, use the YUM package manager:

    sudo yum install lens

    sudo yum-config-manager --add-repo https://downloads.k8slens.dev/rpm/lens.repo

  2. Install or update Lens Desktop.

    sudo yum install lens-el7

Install Lens Desktop with Snap#

  1. Optional. Download and install snap. Find Linux distributions that do not have pre-installed snap and installation instructions in Snap tutorials: Installing snapd.

  2. Install the Lens Desktop snap:

    sudo snap install kontena-lens --classic

Install Lens Desktop from the AppImage#

  1. Download the AppImage file.
  2. Navigate to the directory where you have the file downloaded and right-click the AppImage file and select Properties > Permissions.

  3. Select the Allow executing file as a program check box.

    Note

    Some file managers might offer to unselect the Is executable check box or other similar actions.

  4. In the Linux command line, navigate to the directory where you have the file downloaded and type the following commands:

    chmod +x <file-name.AppImage>
./<file-name.AppImage>

Configure protocol handling#

Protocol handling enables external programs to open Lens Desktop. For AppImage or other manually installed Lens Desktop instances, protocol handling must be enabled separately. Protocol handling is not required to run Lens Desktop but some Lens extensions may rely on it.

Note

It assumed that your Linux distribution uses xdg-open and the xdg-* suite of programs for determining which application can handle custom URIs.

  1. Create a file called lens.desktop in one of the following directories:

    ~/.local/share/applications/

    /usr/share/applications

  2. In lens.desktop, specify the absolute path to the unpacked Lens executable. Specify other parameters as follows:

    [Desktop Entry]
Name=Lens
Exec=<path/to/executable> %U
Terminal=false
Type=Application
Icon=lens
StartupWMClass=Lens
Comment=Lens - The Kubernetes IDE
MimeType=x-scheme-handler/lens;
Categories=Network;

  3. Set the default handler:

    xdg-settings set default-url-scheme-handler lens lens.desktop

    If the operation exits with the 0 code, then Lens Desktop is set up to handle lens:// URIs.

Updating Lens Desktop#

Lens Desktop supports auto-updating. When a new release is available, a notification appears in the application.

In-app auto-updates are available only for exe, dmg, and AppImage installations. The Snap instances are automatically updated through the snapd daemon. Update other Lens Desktop distributions manually.

See Lens Desktop release notes for more information about features, maintenance updates, and other updates.

Backup and restore data#

When updating to a major Lens Desktop version, user data such as clusters, preferences, and other configurations migrates to new data structures. However, we recommend you to back up user data. Find default user data locations below:

OS Path
macOS ~/Library/Application Support/Lens/
Windows %APPDATA%\Lens\
Linux ~/.config/Lens/ or $XDG_CONFIG_HOME/Lens
