# Examples - showing how to disable syncthing with 'disable_sycthing' go build tag.
#            Each mover has its own tag, just using syncthing here as an example.
#
#   Running tests:                   TAGS=disable_syncthing make test
#   Building the manager binary:     TAGS=disable_syncthing make build
#   Running the manger locally:      TAGS=disable_syncthing make run
#   Building the Docker container:   TAGS=disable_syncthing make docker-build
#
#   Notes:
#   1. Building the docker container will still package the binary for the excluded mover(s), syncthing in this case.
#      Changes would need to be made in the Dockerfile to exclude it.
#   2. When running the docker image, flags for the movers may need to be updated (i.e. the deloyment.yaml in the
#      helm chart would also to be updated) to remove passing in the container-image argument
#      (--syncthing-container-image in the example above).
#   2. Running tests currently will not work if you disable rsync or rclone as common tests in controllers
#      depend on them (see setup in suite_test.go for example)
#   3. If you want to disable multiple movers, use a comma separated list of tags like this:
#      TAGS=disable_syncthing,disable_restic

# file as xyz: ## something, and then pretty-format the target and help. Then,
# if there's a line with ##@ something, that gets pretty-printed as a category.
