## Metadata for tags

You can also add additional metadata for the different tags used to group your path operations with the parameter `openapi_tags`.

It takes a list containing one dictionary for each tag.

Each dictionary can contain:

* `name` (**required**): a `str` with the same tag name you use in the `tags` parameter in your *path operations* and `APIRouter`s.

docker-hotfix-push: docker-hotfix
	@docker push -q $(TAG) && echo "Published new container $(TAG)"

docker-hotfix: hotfix-push checks ## builds minio docker container with hotfix tags
	@echo "Building minio docker image '$(TAG)'"
	@docker build -q --no-cache -t $(TAG) --build-arg RELEASE=$(VERSION) . -f Dockerfile.hotfix

docker: build ## builds minio docker container
	@echo "Building minio docker image '$(TAG)'"

HUBS ?= $(HUB)

# If tag not explicitly set in users' .istiorc.mk or command line, default to the git sha.
TAG ?= $(shell git rev-parse --verify HEAD)
ifeq ($(TAG),)
  $(error "TAG cannot be empty")
endif

PULL_POLICY ?= IfNotPresent
ifeq ($(TAG),latest)
  PULL_POLICY = Always
endif
ifeq ($(PULL_POLICY),)

### Ihre Tags verwenden

Verwenden Sie den Parameter `tags` mit Ihren *Pfadoperationen* (und `APIRouter`n), um diese verschiedenen Tags zuzuweisen:

```Python hl_lines="21  26"
{!../../../docs_src/metadata/tutorial004.py!}
```
