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.

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

1. Create a free Codefresh account
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!

A lot of work could be done to streamline this setup flow. Contributors welcome!
