Question about where to find availableReplicas

[Willena]

My actions before raising this issue

• [x] Followed the troubleshooting guide
• [x] Read/searched the docs
• [x] Searched past issues

Expected Behaviour

• The json returned when calling http://gateway:8080/system/functions should return the correct number of availableReplicas for each deployed functions
• The json returned when calling http://gateway:8080/system/function/ should return the correct number of availableReplicas for the functions

Current Behaviour

• For now, http://gateway:8080/system/functions always return 0 availableReplicas for each function in the returned array, whereas http://gateway:8080/system/function/ gives the correct number of availableReplicas

Possible Solution

• Fix the http://gateway:8080/system/functions so that the availableReplicas property get updated.

Steps to Reproduce (for bugs)

1. Create a new swarm
2. Deploy OpenFaas
3. Build and deploy a simple function (for example named: example-func
4. Wait for the function to deploy
5. Call http://gateway:8080/system/function/example-func
6. Observe the number of availableReplicas
7. Call http://gateway:8080/system/functions
8. Look at the array item that corresponds to example-func
9. The availableReplicas value in the object corresponding to example-func is 0 and does not get updated

Context

• Build a simple script that call the API of the gateway to wait for all my app function to be deployed and running on the cluster, in order to start a CI job

Your Environment

• FaaS-CLI version ( Full output from: faas-cli version ): 0.12.4

• Docker version docker version (e.g. Docker 17.0.05 ): 19.03.5

• Are you using Docker Swarm or Kubernetes (FaaS-netes)? Docker swarm

• Operating System and version (e.g. Linux, Windows, MacOS): Linux

• Code example or link to GitHub repo or gist to reproduce problem: X

• Other diagnostic information / logs from troubleshooting guide: X

This is as designed, for the replica count you need to use the status URL

/system/function/NAME

Then why the availableReplicas property is also present in the returned objects of /system/functions if it is useless ?
