start: ##@application Start application in containers.

test: ##@application Run tests
	cd portclient && go test ./...

proto: ##@gRPC Generate code from proto file. Requires protoc installs. Would be better to run this in a container to have all the dependencies inside it.
	protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative portsvc/proto/ports.proto

build: ##@docker Builds all images from the Dockerfiles and applies two tags: 'latest' and provided tag e.g, tag=0.0.1 make build
	docker build --no-cache -f Dockerfile_client -t $(IMAGE_NAME_CLI):$(IMAGE_TAG) -t $(IMAGE_NAME_CLI):$(SEMVER_IMAGE_TAG) . && \
	docker build --no-cache -f Dockerfile_service -t $(IMAGE_NAME_SVC):$(IMAGE_TAG) -t $(IMAGE_NAME_SVC):$(SEMVER_IMAGE_TAG) .

push: ##@docker Pushes image to Docker with tags: 'latest' and provided tag e.g. tag=0.0.1 make push
	docker push $(IMAGE_NAME_CLI):$(SEMVER_IMAGE_TAG) && \
    docker push $(IMAGE_NAME_CLI):$(IMAGE_TAG) && \

# If it finds a file matching a command, it tells you it's already up to date.
