# Shared Makefile logic for the LocalStack Terraform samples.
#
# Include it from a sample directory:
#
#     include ../common.mk
#
# Customise a sample by setting any of these variables BEFORE the include:
#   TEST_CMD      - command run by the `test` target          (default: ./run.sh)
#   INIT_CMD      - command run by the `init` target          (default: lstk terraform init)
#   DEPLOY_CMD    - command run by the `deploy` target        (default: lstk terraform apply)
#   INSTALL_EXTRA - extra command run by the `install` target (default: check for terraform)
#   DEPLOY_STEPS  - targets chained by `run` and `test-ci`     (default: start install init deploy test)
#
# Use `=` (deferred) for any value that references $(LSTK) or $(PYTHON_BIN),
# since those are defined below, after the point the sample sets its overrides.
