I have the following skaffold:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  namespace: default
  labels:
    app: nginx
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:            
      containers:
        - name: nginx-base
          image: us-central1-docker.pkg.dev/registry/nginx/base:latest
          imagePullPolicy: Always

and am using the following cloud deploy command to deploy it:

gcloud deploy releases create "my-deployment-001" 
    --delivery-pipeline my-pipeline 
    --project my-project 
    --region us-central1 
    --annotations "$annotations" 
    --skaffold-file "path/to/skaffold.yaml" 
    --images "nginx-base=us-central1-docker.pkg.dev/registry/nginx/base:<IMAGE TAG>"

It seems that the nginx-base image is not being given the correct tag. Here’s part of of the rendered skaffold:

        - image: us-central1-docker.pkg.dev/registry/nginx/base:latest
          imagePullPolicy: Always

which still contains the old tag. I’ve tried setting the images flag to something like old-url:latest=new-url:tag, but that doesn’t seem to work either. the documentation seems to imply that one of these would work.

What am I doing wrong?
