Audience Questions from the 2.6 Webinar

Q: Hans Asks: Is 2.6 backward compatible? In other words, can I use a 2.5 configuration and use that with 2.6 without changing anything?

A: Yes, the Traefik 2.6 is backward compatible with the 2.5 version. However, please ensure that all CRD’s are updated before upgrading to the latest version. In the 2.6 releases we have added the new TCP middleware and that the TCP middleware CRD has to be updated. The good practice is to always keep the CRD’s up to date.

Q: Sascha asks: Is secret Management within Deployment with Vault only possible via Kubernetes or is Docker Swarm fully supported?

A: Based on my best knowledge Docker Swarm supports Vault for secret management but personally I don’t have experience with such integration.

Getting started with Traefik on Kubernetes, Traefik Workshop #1

1. I am interested in monitoring traefik with Datadog. Is this workshop with this topic?

There is no dedicated workshop with the monitoring Traefik by using Datadog. I’ve found in Datadog docs how to configure DataDog Agent and tune Traefik configuration to collect the data. However, I’ve not tested that setup.

2. In terms of Capabilities, how would Traefik provide a value add over some in-built services such as Azure LB or App Gateway?

Here are just a few of advantages by using Traefik:
