To implement this we should add a query language that allows us to list application that match the query. For a first release the supported conditions should be:
- [ ] Is the label key set?
- [ ] Does the label value equal some value?
- [ ] Multiple selector must match
Eventually we should support something similar to kubernetes query language. We need to make sure that whatever we implement now should allow us to extend it to implement the full query language without breaking existing applications that use this query language.
