Spurious warning when using only remote manifests

[ekuefler]

Expected behavior

I should be able to define a kubectl deploy using only remoteManifests without any issues.

Actual behavior

If I only define remoteManifests, I get a warning like this when running skaffold run:

Starting deploy...
WARN[0001] k8s/*.yaml did not match any file            
 - deployment.apps/manager configured
Waiting for deployments to stabilize...
Deployments stabilized in 13.710431ms

Information

• Skaffold version: v1.23.0
• Operating system: Linux
• Installed via: skaffold.dev
• Contents of skaffold.yaml:

apiVersion: skaffold/v2beta15
kind: Config
metadata:
  name: environments
build:
  ...
deploy:
  kubectl:
    remoteManifests:
    - environments-system:deployment/manager

Notes

I get the same warning if I explicitly set manifests to an empty array. I think there just needs to be a check against remoteManifests here:

skaffold/pkg/skaffold/schema/defaults/defaults.go

Line 199 in fb9c352

if c.Deploy.KubectlDeploy != nil && len(c.Deploy.KubectlDeploy.Manifests) == 0 {

.

Thanks @ekuefler. We will try to clean up this up in our next sustainability sprint
