## Basic targets.
##
## This Makefile wraps basic build and test targets for ease-of-use. Bazel
## is run inside a canonical Docker container in order to simplify up-front
## requirements.
##
## There are common arguments that may be passed to targets. These are:
## OPTIONS - Build or test options.
## TARGETS - The bazel targets.
## ARGS - Arguments for run or sudo.
##
## Additionally, the copy target expects a DESTINATION to be provided.
##
## For example, to build runsc using this Makefile, you can run:
## make build OPTIONS="" TARGETS="//runsc"'
##
help: ## Shows all targets and help from the Makefile (this message).

awk 'BEGIN {FS = "(:.*?|)## ?"}; { \

printf " \033[36m%-20s\033[0m %s\n", $$1, $$2; \
} else { \
printf "%s\n", $$2; \
} \
}'
build: ## Builds the given $(TARGETS) with the given $(OPTIONS). E.g. make build TARGETS=runsc
test: ## Tests the given $(TARGETS) with the given $(OPTIONS). E.g. make test TARGETS=pkg/buffer:buffer_test
copy: ## Copies the given $(TARGETS) to the given $(DESTINATION). E.g. make copy TARGETS=runsc DESTINATION=/tmp
run: ## Runs the given $(TARGETS), built with $(OPTIONS), using $(ARGS). E.g. make run TARGETS=runsc ARGS=-version
sudo: ## Runs the given $(TARGETS) as per run, but using "sudo -E". E.g. make sudo TARGETS=test/root:root_test ARGS=-test.v
.PHONY: help build test copy run sudo
# Load all bazel wrappers.
#
# This file should define the basic "build", "test", "run" and "sudo" rules, in
# addition to the $(BRANCH_NAME) variable.

## Docker image targets.
##
## Images used by the tests must also be built and available locally.
## The canonical test targets defined below will automatically load
## relevant images. These can be loaded or built manually via these
## targets.
##
## (*) Note that you may provide an ARCH parameter in order to build
## and load images from an alternate archiecture (using qemu). When
## bazel is run as a server, this has the effect of running an full
## cross-architecture chain, and can produce cross-compiled binaries.

## These targets faciliate local development by automatically
## installing and configuring a runtime. Several variables may
## be used here to tweak the installation:
## RUNTIME - The name of the installed runtime (default: branch).
## RUNTIME_DIR - Where the runtime will be installed (default: temporary directory with the $RUNTIME).
## RUNTIME_BIN - The runtime binary (default: $RUNTIME_DIR/runsc).
## RUNTIME_LOG_DIR - The logs directory (default: $RUNTIME_DIR/logs).
## RUNTIME_LOGS - The log pattern (default: $RUNTIME_LOG_DIR/runsc.log.%TEST%.%TIMESTAMP%.%COMMAND%).
