When running skaffold dev with a container that has a listener (in this case Express), the container hangs as expected.
If I remove the listener with simple executable code, it keeps running it over and over.

I tried to search in the documentation but all I can see is that Skaffold should re-run the code only if you make changes.

I expected Skaffold would terminate the container after the run.
Are the restarts a normal behavior? Should I only add to Skaffold services that have listeners?

The following code results in seeing the “test” console.log every few seconds.

skaffold.yaml

apiVersion: skaffold/v2alpha3
kind: Config
deploy:
  kubectl:
    manifests:
      - ./dpl/*
build:
  local:
    push: false
  artifacts:
    - image: myuser/myworker
      context: myworker
      docker:
        dockerfile: Dockerfile
      sync:
        manual:
          - src: 'src/**/*.ts'
            dest: .

index.ts

//import express from 'express'

//const app = express()


console.log('test')

//app.listen(3000, () => {
//  console.log('Listening on port 3000!')
//})
