  cat <<HELP
This script will run the Kiali molecule tests within an existing OpenShift cluster.
It tests the latest published images, but has options to allow you to test dev images
built from specified branches, thus allowing you to test PRs and other dev builds.

You can use this as a cronjob to test Kiali periodically.

Some of the defaults used by this script assume you started the cluster via the script
provided by https://github.com/kxr/ocp4_setup_upi_kvm - see that project for more details.

To use your own existing OpenShift cluster, you will want to look at the
options -kp (or -kpf), -ku, and -oapi.

Options:

-at|--all-tests <tests>
    Space-separated list of all the molecule tests to be run.
    Note that this list may not be the tests that are actually run - see --skip-tests.
    Default: <all tests in kiali-operator repo /molecule directory>

-dorp|--docker-or-podman <docker|podman>
    What to use when building images.
    Default: docker

-gcp|--git-clone-protocol <git|https>
    Determine what protocol to use when git cloning the repos.
    If you want to upload logs (-ul true), you must set this to "git".
    Default: git

-hb|--helm-branch <branch name>
    The helm-chart branch to clone.
    Default: master

-hf|--helm-fork <name>
    The helm-chart fork/org to clone.
    Default: kiali

-ii|--install-istio <true|false>
    If true, an Istio control plane will be installed
    in 'istio-system' namespace if one does not already exist.
    If false, and no Istio is installed, this script aborts.
    If you elect to install Istio, you can indicate which
    Istio version you want via -iv option.
    Default: true

-ir|--irc-room <irc room name>
    The libera IRC room to send the results message.
    Set to "" to not send any message.
    Default: kiali-molecule-tests

-iv|--istio-version <#.#.#>
    The version of Istio you want to install.
    This option is ignored if -ii is false.
    If not specified, the latest version of Istio is installed.
    Default: <the latest release>

-kb|--kiali-branch <branch name>
    The kiali branch to clone.
    Default: master

-kf|--kiali-fork <name>
    The kiali fork/org to clone.
    Default: kiali

-kob|--kiali-operator-branch <branch name>
    The kiali-operator branch to clone.
    Default: master

-kof|--kiali-operator-fork <name>
    The kiali-operator fork/org to clone.
    Default: kiali

-kp|--kubeadmin-pw <password>
    The password for the kubeadmin user.
    If you want this more secure, put the password in a file and use -kpf.
    Default: <unset>

-kpf|--kubeadmin-pw-file <filename>
    The file containing the kubeadmin password. If the file is not readable by the user
    running this script, the script will attempt to read it via "sudo".
    Default: /root/ocp4_cluster_ocp4/install_dir/auth/kubeadmin-password

-ku|--kubeadmin-user <username>
    A username that has kubeadmin permissions.
    Default: kubeadmin

-lb|--logs-branch <branch name>
    The logs branch to clone.
    Default: openshift

-lf|--logs-fork <name>
    The logs fork/org to clone.
    Default: jmazzitelli

-lpn|--logs-project-name <name>
    The project name within the logs fork/org to clone.
    Default: kiali-molecule-test-logs

-oapi|--openshift-api <OpenShift API URL>
    The URL to the OpenShift API. This is the endpoint used by "oc login".
    Default: https://api.ocp4.local:6443

-oc <path to oc>
    The full path to the 'oc' command.
    If 'oc' is in your PATH, you can pass the option as '-oc \$(which oc)'
    Default: /root/ocp4_cluster_ocp4/oc

-oi|--operator-installer <helm|skip>
    How the operator is to be installed by the molecule tests. It is either installed
    via helm or the installation is skipped entirely. Use "skip" if you installed the
    operator yourself (say, via OLM) and you want the molecule tests to use it rather
    than to install its own operator.
    Default: helm

-sd|--src-dir <directory>
    Where the git source repositories will be cloned.
    Default: /tmp/KIALI-GIT

-st|--skip-tests <tests>
    Space-separated list of all the molecule tests to be skipped.
    Default: <tests that are unable to be run on OpenShift>

-sv|--spec-version <version>
    When the molecule tests create Kiali CR resources, this will be the value of
    the spec.version field. This effectively is how you can test different
    playbooks in the operator.

-udi|--use-dev-images <true|false>
    If true, the tests will use locally built dev images of Kiali and the operator.
    When using dev images, this script will attempt to build and push dev images
    into your cluster. If your environment is not set up for development
    (e.g. you do not have Go installed), then this script will fail.
    If false, the cluster will simply pull the 'latest' images published on quay.io.
    Default: false

-udsi|--use-default-server-image <true|false>
    If true (and --use-dev-images is 'false') no specific image name or version will be specified in
    the Kiali CRs that are created by the molecule tests. In other words, spec.deployment.image_name and
    spec.deployment.image_version will be empty strings. This means the Kial server image that will be deployed
    in the tests will be determined by the operator defaults. This is useful when testing with a specific
    spec.version (--spec-version) and you want the operator to install the default server image for that version.
    Default: false

-ul|--upload-logs <true|false>
    If you want to upload the logs to the git repo, set this to true.
    Otherwise, set this to false. The logs will remain on the local machine,
    but will not be committed to the remote git repo.
    If the IRC message will be sent, you can at least be told if there were
    failures during any one of the tests.
    Default: false
