Skaffold: Skaffold doesn't display changes until restarting

[Hudsonzp]

Expected behavior

Upon skaffold syncing a file, I can refresh my browser and see the changes made to the application.

Actual behavior

Even though the file syncs and appears to be going into the proper image, no changes can bee seen until skaffold is interrupted and restarted. Most times it's 1-2 changes behind (example in steps to reproduce).

Information

• Skaffold version: v0.26.0
• Operating system: MacOS Mojave v10.14.3
• Contents of skaffold.yaml:

apiVersion: skaffold/v1beta7
kind: Config
build:
  local:
    push: false
  artifacts:
    - image: test/dev-client
      docker:
        dockerfile: Dockerfile.dev
      context: ./client
      sync:
        '**/*.css': .
        '**/*.scss': .
        '**/*.js': .
    - image: test/dev-server
      docker:
        dockerfile: Dockerfile.dev
      context: ./server
      sync:
        '**/*.py': .
deploy:
  kubectl:
    manifests:
      - k8s-dev/client-cluster-ip-service.yaml
      - k8s-dev/client-deployment.yaml
      - k8s-dev/ingress-service.yaml
      - k8s-dev/server-cluster-ip-service.yaml
      - k8s-dev/server-deployment.yaml

Steps to reproduce the behavior

Page says: Success

1. Changed in code to: Successes
2. After syncing page says: Success
3. Changed in code to: "This is a test for success"
4. After syncing page says: Success
5. --interrupt skaffold--
6. --skaffold dev--
7. Page says: Successes

I've tried hard refreshing, clearing cache, etc. This is happening on 2-3 different computers as well in different browsers. This happens no matter if it's a python change or a react/webpack change.

Setup:

• Docker for Mac running my Kubernetes cluster.
• Microservices with python/flask and react.
• The only other Kubernetes files not included in my skaffold manifest are postgres-ip, postgres-pvc, and postgres-deployment.

Happy to provide any other files or setup information. It's such a weird issue.

[martinsoender]

I'm experiencing the same issue.

[corneliusweig]

@Hudsonzp Can you make sure that you are syncing to the correct destination? Currently the way how the pattern **/*.js works is that it does not recreate subdirectories at the destination. In other words, it puts all matched files flat into the dest directory.
Please try the (currently undocumented #1837) pattern ***/*.js to achieve directory syncing. Does that solve your issue?

[Hudsonzp]

Worked like a charm @corneliusweig. I swapped the pattern for py, scss, js, and my css files. First try I could refresh the page and intended changes. We can close this ticket.

Thanks for your help!
