Run Linkerd integration tests.

Optionally specify one of the following tests: [upgrade helm helm-upgrade uninstall deep external-issuer]

Usage:
    tests [--images] [--images-host ssh://linkerd-docker] [--name test-name] [--skip-kind-create] /path/to/linkerd

Examples:
    # Run all tests in isolated clusters
    tests /path/to/linkerd

    # Run single test in isolated clusters
    tests --name test-name /path/to/linkerd

    # Skip KinD cluster creation and run all tests in default cluster context
    tests --skip-kind-create /path/to/linkerd

    # Load images from tar files located under the 'image-archives' directory
    # Note: This is primarly for CI
    tests --images /path/to/linkerd

    # Retrieve images from a remote docker instance and then load them into KinD
    # Note: This is primarly for CI
    tests --images --images-host ssh://linkerd-docker /path/to/linkerd

Available Commands:
    --name: the argument to this option is the specific test to run
    --skip-kind-create: skip KinD cluster creation step and run tests in an existing cluster.
    --images: (Primarily for CI) use 'kind load image-archive' to load the images from local .tar files in the current directory.
    --images-host: (Primarily for CI) the argument to this option is used as the remote docker instance from which images are first retrieved (using 'docker save') to be then loaded into KinD. This command requires --images.
