# This script runs inside a Prow job. It can run unit tests ("make test")
# and E2E testing. This E2E testing covers different scenarios (see
# https://github.com/kubernetes/enhancements/pull/807):
# - running the stable hostpath example against a Kubernetes release
# - running the canary hostpath example against a Kubernetes release
# - building the component in the current repo and running the
# stable hostpath example with that one component replaced against
# a Kubernetes release
#
# The intended usage of this script is that individual repos import
# csi-release-tools, then link their top-level prow.sh to this or
# include it in that file. When including it, several of the variables
# can be overridden in the top-level prow.sh to customize the script
# for the repo.
#
# The expected environment is:
# - $GOPATH/src/<import path> for the repository that is to be tested,
# with PR branch merged (when testing a PR)
# - running on linux-amd64
# - kind (https://github.com/kubernetes-sigs/kind) installed
# - optional: Go already installed

# By default, this script tests sidecars with the CSI hostpath driver,
# using the install_csi_driver function. That function depends on
# a deployment script that it searches for in several places:
#
# - The "deploy" directory in the current repository: this is useful
# for the situation that a component becomes incompatible with the
# shared deployment, because then it can (temporarily!) provide its
# own example until the shared one can be updated; it's also how
# csi-driver-host-path itself provides the example.
#
# - CSI_PROW_DRIVER_VERSION of the CSI_PROW_DRIVER_REPO is checked
# out: this allows other repos to reference a version of the example
# that is known to be compatible.
#
# - The <driver repo>/deploy directory can have multiple sub-directories,
# each with different deployments (stable set of images for Kubernetes 1.13,
# stable set of images for Kubernetes 1.14, canary for latest Kubernetes, etc.).
# This is necessary because there may be incompatible changes in the
# "API" of a component (for example, its command line options or RBAC rules)
# or in its support for different Kubernetes versions (CSIDriverInfo as
# CRD in Kubernetes 1.13 vs builtin API in Kubernetes 1.14).
#
# When testing an update for a component in a PR job, the
# CSI_PROW_DEPLOYMENT variable can be set in the
# .prow.sh of each component when there are breaking changes
# that require using a non-default deployment. The default
# is a deployment named "kubernetes-x.yy${CSI_PROW_DEPLOYMENT_SUFFIX}" (if available),
# otherwise "kubernetes-latest${CSI_PROW_DEPLOYMENT_SUFFIX}".
# "none" disables the deployment of the hostpath driver.
#
# When no deploy script is found (nothing in `deploy` directory,
# CSI_PROW_DRIVER_REPO=none), nothing gets deployed.
#
# If the deployment script is called with CSI_PROW_TEST_DRIVER=<file name> as
# environment variable, then it must write a suitable test driver configuration
