Installs the Authorino Operator and dependencies to the current kubectl context.

Usage:

  install.sh [options]

Options:

  -v | --version    The version of the Authorino Operator to install. Defaults to 'latest'.
       --git-ref    The Git reference of the Authorino Operator to install.
                    Provide it in the form of a branch, tag or commit hash, alternatively to providing a version.
                    If omitted, the Git reference will be inferred from the version.
       --no-deps    Do not install dependencies.
       --dry-run    Print the commands that would be executed, but do not execute them.
  -h | --help       Print this help message.
