Makefile

# To run locally:
# The Makefile will run against a workspace that is expected to have the installer, istio.io/istio and
# istio.io/tools repositories checked out. It will copy (TODO: or mount) the sources in a KIND docker container that
# has all the tools needed to build and test.
#
# "make test" is the main command - and should be used in all CI/CD systems and for clean local testing.
#
# For local development, after 'make test' you can run individual steps or debug - the KIND cluster will be wiped
# the next time you run 'make test', but will be kept around for debugging and repeat tests.
#
# Example local workflow for development/testing:
#
# export KIND_CLUSTER=local # or other clusters if working on multiple PRs
# export MOUNT=1            # local directories mounted in the docker running Kind and tests
# export SKIP_KIND_SETUP=1  # don't create new cluster at each iteration
# export SKIP_CLEANUP=1     # leave cluster and tests in place, for debugging
# export ONE_NAMESPACE=1    # deploy all Istio components in one namespace
#
# - prepare cluster for development:
#     make prepare
# - install or reinstal istio components needed for test (repeat after rebuilding istio):
#   This step currently needs uploaded images or 'kind load' to copy them into kind.
#   (TODO: build istio in the kind container, so we don't have to upload)
#
#     make TEST_TARGET="install-base"
#
# - Run individual tests using:
#     make TEST_TARGET="run-simple" # or other run- targets.
#  alternatively, run "make kind-shell" and run "make run-simple" or "cd ...istio.io/istio" and go test ...
#  The tests MUST run inside the Kind container - so they have access to 'pods', ingress, etc.
#
#  On the host, you can run "ps" and dlv attach for remote debugging. The tests run inside the KIND docker container,
#  so they have access to the pods and apiserver, as well as the ingress and node.
#
# - make clean - when done
#
# - make kind-shell  - run a shell in the kind container.
# - make kind-logs - get logs from all components
#
# Fully hermetic test:
# - make test - will clean 'test' KIND cluster, create a new one, run the tests.
# In case of failure:
# - make test SKIP_KIND_SETUP=1 SKIP_CLEANUP=1 TEST_TARGET=(target that failed)
