Traefik Support

[mikesir87]

In addition to the current controllers, it would be great to support Traefik!

The TraefikService object supports the ability for weighted round robin load balancing and traffic mirroring when using Traefik as ingress.

As a quick pass, an IngressRoute is configured to send traffic to a TraefikService, which then provides configuration for sending traffic to one or more Kubernetes Service objects. While I haven't dived into Argo's architecture, I imagine it wouldn't be too complicated to own and manage the TraefikService object.

While I may not be the best to contribute code, I could try or help with docs and testing the implementation. Or if someone wants to chat on Slack and give me direction on how/where to get started, I can take a crack at it.

we already use traefik ingressroute for blue/green deployment, we would like to try rollout once it supports traefik

We want to leverage traefk for cananry deployment.
I tried following the document to use traefik for traffic management with canary
https://troy.wang/docs/kubernetes/posts/argo-rollouts-support-traefik/
It failed, with below error.

$ kubectl apply -f nginx-rollout.yaml -n argo-demo
error: error validating "nginx-rollout.yaml": error validating data: ValidationError(Rollout.spec.strategy.canary.trafficRouting): unknown field "traefik" in io.argoproj.v1alpha1.Rollout.spec.strategy.canary.trafficRouting; if you choose to ignore these errors, turn validation off with --validate=false

what code level changes i need to do to make it work? since it's written in Chinese, I am finding it difficult to follow.
@debu99 can u help me here

It seems that Traefik will have an implementation for the Kubernetes Gateway API https://gateway-api.sigs.k8s.io/implementations/#traefik

So Traefik support might be available after implementing #1438

Can I take it please ?
