This is a simple web app serving as a helmfile spec example

About

Simpleapp is a simple web app on flask/python:3.8

Navigate to http://localhost:5000/log

Expected output:

{'bar': 'foobar'}

Helmfile is a declarative spec for deploying helm charts. It lets you...

  • Keep a directory of chart value files and maintain changes in version control.
  • Apply CI/CD to configuration changes.
  • Periodically sync to avoid skew in environments.

Generate charts

$ helmfile repos
Adding repo stable https://charts.helm.sh/stable
"stable" has been added to your repositories

A lot of YAML files should be in output like:

$ helmfile template --skip-deps
Templating release=ingress-controller, chart=stable/nginx-ingress
