# Standard Development Targets
# build - build the project, binaries go into ./bin
# build-image - build a Docker image with the virtual-kubelet binary
# clean - clean up built binaries and cached Go artifacts
# lint - run golangci-lint (set args in LINT_ARGS)
# tidy - "go mod tidy"

# Use the sha for the build as a version for now.

# since commit shas have no order
# BUILD_DATE ?= $(shell date -u '+%Y-%m-%d-%H:%M UTC')
