Color Coded - Istio + Helm + Codefresh Demo App

What's in the app?

A simple go app that displays a color and dies when you navigate to /die. The whole thing is packaged as a Helm chart and includes a Codefresh pipeline, and Istio configuration.

You can watch a full demo here.

Installation and usage

Some effort will be requried to streamline the setup for testing but it's possible now. These instructions may be incomplete.

2. Fork and add this repo to Codefresh and start with a Codefresh YAML '.codefresh/helm-canary.yml'
3. Set the environmental variables
4. Add a Kubernetes cluster to your Codefresh account.
5. Install Istio and Helm
6. Update DNS with your Istio gateway IP address.
7. Update and deploy the istio gateway configuration under istio/canary
8. Update the base canary configuration under istio/canary.yml with your app info.
9. Install the Helm package once manually (pull this repo, run a helm install) helm install --name colors ./deploy/helm/colors/ --namespace=color-coded --set deployment[0].image.pullSecret="codefresh-generated-r.cfcr.io-cfcr-color-coded"
10. Review the Codefresh yml and update any remaining variables (like Kubernetes context)
11. Deploy!
