Description

Expected behavior

Skaffold resyncs files after a breaking change causes a pod to redeploy

Actual behavior

Skaffold doesn't do anything - it will continue to sync files to the new pod when changes are made but previous changes are ignored. I understand the files are synced to the pod rather than the container, but this requires skaffold dev to be restarted if the pod ever crashes.

Information

  • Skaffold version: v1.33.0
  • Operating system: MacOS 11.6
  • Installed via: Homebrew
  • Contents of skaffold.yaml:
  - image: myapp
    context: myapp
    docker:
      dockerfile: myapp.Dockerfile
    sync:
      infer:
      - '**'

Steps to reproduce the behavior

  1. setup skaffold with file sync
  2. once stable, make a change to trigger the file sync
  3. delete the pod that the file was synced to
  4. examine the new pod, the content isn't synced on pod standup

Contributor guide

Research direction
Investigate the sync behavior when pods are recreated; trace the code path for file sync state upon pod deployment.
