@adamsitnik, Do we need more overload same as other health checks?

[Alirexaa]

@smnsht, could you add Milvus to labeler.yml and also add healthchecks_milvus.yaml same as other actions?

[smnsht]

@Alirexaa
I've created 3 workflow files & updated labeler.yml

I have to add milvus docker image to healthchecks_milvus_ci.yml - not done yet. I'm checking how I can verify GitHub workflow (unfamiliar to me).

You can see an example below:
https://github.com/Xabaril/AspNetCore.Diagnostics.HealthChecks/blob/65ab619b0e5dcf27940a1a6baf13cc1ad4f79903/.github/workflows/healthchecks_elasticsearch_ci.yml

Also for passing the functional test you need to add milvus container to the actions.
example:

AspNetCore.Diagnostics.HealthChecks/.github/workflows/healthchecks_elasticsearch_ci.yml

Lines 31 to 36 in 65ab619

	elasticsearch:
	image: docker.elastic.co/elasticsearch/elasticsearch:6.3.2
	ports:
	- 9300:9300
	- 9201:9200

Done with GitHub workflow. Tested on my personal account - looks good.
