registry host when pushing image is `unknown`

[XBeg9]

Steps to Reproduce

I have this weird behaviour from vscode devcontainer, any ideas why my host for registry is unknown ?

ctlptl create cluster k3d --registry=ctlptl-registry

k8s_yaml('k8s/ingest.yaml')

docker_build('ingest-image', 
  dockerfile='./services/Dockerfile.ingest', 
  context='./services',
  live_update=[
      sync('./services/ingest.py', '/opt/services/ingest.py'),
      ]
)

apiVersion: apps/v1
kind: Deployment
metadata:
  name: ingest
  labels:
    app: ingest
spec:
  selector:
    matchLabels:
      app: ingest
  template:
    metadata:
      labels:
        app: ingest
    spec:
      containers:
        - name: ingest
          image: ingest-image
          ports:
            - containerPort: 3000

Current Behavior

Pushing unknown:55347/ingest-image:tilt-f179af15c6e37548
     Pushing with Docker client
     Authenticating to image repo: unknown:55347
     Sending image data

ok, I was able to fix it running commands separately

ctlptl create registry registry --port=5005
ctlptl create cluster k3d --registry=registry

tilt doctor

how is the devcontainer set up?

can you try this with the latest version of ctlptl? we made some improvements to the registry resolution logic in 0.8.35
