Node.js component with hot-reload

Node.js example demonstrating the file synchronization mode.

Init

Deploy component from stack template once to render templates with SuperHub stack parameters:

make deploy COMPONENT=skaffold-nodejs

Alternativelly, edit skaffold.yaml and templates/deployment.yaml to set Docker image, and templates/ingress.yaml to set ingress hostname. Then:

skaffold dev --kube-context $DOMAIN_NAME [--namespace default] [--default-repo <myrepo>] [--port-forward] [--cleanup=false]

Workflow

• Make some changes to index.js:
  • The file will be synchronized to the cluster
  • nodemon will restart the application
• Make some changes to package.json:
  • The full build/push/deploy process will be triggered, fetching dependencies from npm
