Install the Gloo Edge command line tool (CLI)

You can install the Gloo Edge command line, glooctl, to help install, configure, and debug Gloo Edge. Depending on your operating system, you have several installation options.

Update glooctl CLI version

When it’s time to upgrade Gloo Edge, make sure to update the glooctl version before upgrading.

You can use the glooctl upgrade command to upgrade or roll back the glooctl version. For example, you might change versions during an upgrade process, or when you have multiple versions of Gloo Edge across clusters that you manage from the same workstation. For more options, run glooctl upgrade --help.

  1. Set the version to upgrade glooctl to in an environment variable. Include the patch version. For Gloo Edge Enterprise, specify the Gloo Edge OSS version that corresponds to the Gloo Edge Enterprise version you want to upgrade to. To find the OSS version that corresponds to each Gloo Edge Enterprise release, see the Gloo Edge Enterprise changelogs.

    export GLOOCTL_VERSION=<version>
  2. Upgrade your version of glooctl.

    glooctl upgrade --release v${GLOOCTL_VERSION}

Verify the installation or update

Verify the glooctl CLI is installed and running the appropriate version. In the output, the Client is your local version. The Server is the version that runs in your cluster, and is undefined if Gloo Edge is not installed yet.
