How to use daemonset type install traefik?

[travisghansen]

Several reasons potentially, as I see it generally DaemonSet would likely be used in environments that:

• Do not have support for LoadBalancer services

and/or

• Are fronting the cluster with an external/existing load balancer

It's certainly not uncommon for Ingress controllers to be installed as a DaemonSet using host networking.

Another reason, installing a microk8s on a single vm and wanted to use traefik as default ingress controller.

Fixed by #298

Yes, this would be really nice to have for self-managed clusters with no LoadBalancer service by cloud provider, for example Hetzner Cloud. By the way, nginx-ingress chart has DaemonSet possibility.

The documentation until v2 explicitly mentioned a DaemonSet install: https://docs.traefik.io/v1.7/user-guide/kubernetes/#deploy-traefik-using-a-deployment-or-daemonset

If you are unsure which to choose, start with the Daemonset.

Our use case for DaemonSet-Install:

Cluster in EKS with two Node Pools:

Pool 1: Workers - Not put in any target group
Pool 2: Ingress Nodes - Automatically spawn into a "ingress" target group and get node label app=ingress

We then would install traefik as DaemonSet on app=ingress Nodes and provision an terraform-managed ALB with forwards to that target group.

At least that was the way to go with ingress-nginx and it was nice. But now we need more features from our ingress controller.

why you want to install traefik as daemonset?
it could be done by manually modify the templates but by defaukt traefik will run as standard deployments i think.

Thank you @davidalger for the #298, which allows using Deamonset with Traefik.
