traefik-helm-chart VS hub

helm chart Traefik Ingress

For an example, consider the NGINX Ingress Controller Helm Chart and the Traefik Ingress Controller Helm Chart. Both of these charts install an IngressController but they have their own set of features, configuration, and operation. While they do similar things, they are not the same. Rather than having to pull a bunch of yaml files from a github repo, you can execute a helm install after telling helm where the definition of the charts comes from for a given application. Helm will then go and fetch all the manifests contained in the chart and populate values into the manifest from its defined defaults merged with any values that you specify as an override (or option). If another version of the application comes out, rather than having to update everything, you can just run helm upgrade to update the release to a newer chart version (which may update the internal application code). If the chart version didn't change, but you need a newer release version, a lot of times this is handled by a version variable that you can specify. You just update that (either on the command line or in a values file) and run helm upgrade to change the manifests that get pushed and automatically your deployments will get updated.

Traefik was deployed using Traefik's chart (https://github.com/traefik/traefik-helm-chart). Reading the default values.yaml file, I understand that the Prometheus metrics endpoint is enabled by default. I can confirm that I see the metrics when I access the pod on port 9100/metrics/.

You can Just use the Traefik V2 Helm Chart https://github.com/traefik/traefik-helm-chart

A thousand times, yes. I've wanted to write this same article. Thanks for saving me the time!

The industry is going to great lengths to avoid writing configuration in any ubiquitous imperative programming language. We're seeing the proliferation of hyper-specialized, clunky declarative languages with sub-par tooling and package ecosystems. In what world are templates acceptable code? I don't mean to pick on anything specific, but this[0] is the most recent example I've come across, and it's far from the most unreadable examples.

I have Traefik 2 as my ingress controller acting as the reverse proxy, deployed via Helm. I am using the Bitnami Helm chart to deploy wordpress.

You can then use helm to remove the old traefik deployment and install from wherever you'd prefer. I used the official traefik helm. I made sure that I copied the values from /var/lib/rancher/k3s/server/manifests/traefik.yaml to my values file (retrieved from https://github.com/traefik/traefik-helm-chart/blob/master/traefik/values.yaml). Here I also added the helm operator ports.web.redirectTo: websecure (per u/soundwave_rk).

Traefik Helm chart has 402 stars, but the problem here is that 100 people can use it and they don't add stars since they don't log in to GitHub for it. I don't star Debian packages either.

Let's now install a helm chart from an opensource oci repository (ref: https://artifacthub.io/); Just for an example we will install nginx chart.

Helm charts are stored in a chart repository. This repository analogy is similar to docker hub where you can pull or push images. In a chart repository, you can also pull your charts from the repository and update the repository locally for you to use the chart. The repository that hosts Helm charts is ArtifactHub. ArtifactHub is a web based application that enables finding, installing and publishing Kubernetes packages and configurations. Searching for the helm charts can be done in two ways:

When you're on the lookout for readily deployable and customizable applications to integrate into your cluster, your ideal destination is ArtifactHub. This centralized platform serves as a comprehensive resource, gathering an array of public Helm Chart links for your convenience.

Helm has an official Helm Chart repository called ArtifactHub where developers can push and publish their Helm Charts. In this repository, you can easily find Helm charts for any Kubernetes application and reuse them. For complex applications like Jenkins, it is best to use the official Jenkins Helm Chart. Many Developers have contributed to the Jenkins Helm chart and it has all the Kubernetes YAML files. It will save us time in creating our custom Jenkins Helm chart. In this tutorial will search and download the official Jenkins Helm Chart from ArtifactHub. We will then install the official Jenkins Helm Chart on the Kubernetes Cluster using Helm. Let's install Helm.

The next time you want to search for public Helm Charts, I recommend first searching through Artifact Hub (sort by Stars).

You can also add the artifacthub repo file, to claim ownership, it's optional though.
