Video: Learning Flux and Installing To Homelab

In this video I set up Flux running in a local cluster on my MacBook by following the getting started guide. Then I learn about how to structure the repo according to Flux methodology. I implement this structure in my homelab repo and deploy flux to my homelab cluster. Then I manage to configure Grafana and the Weave UI to be accessbible via ingress using a custom fake domain.

Notes:

kustomization resources live in the cluster
source resources also live in the cluster
To suspend updates for a kustomization, run the command flux suspend kustomization .
To resume updates run the command flux resume kustomization .
use flux reconcile source git podinfo to force a sync, nn waiting
love the fact that helm releases are still accessible and visible on the cluster
flux is just managing helm for you based on code
love the fact that weave dashboard is also part of the cluster manifests
learned about Kubernetes controllers
an operator is a controller
basically everything that enables CRD’s to run is a controller

“A kubernetes controller is a control loop that watches the shared state of the cluster through the apiserver and makes changes attempting to move the current state towards the desired state”

Sources

A Source defines the origin of a repository containing the desired state of the system and the requirements to obtain it (e.g. credentials, version selectors). For example, the latest 1.x tag available from a Git repository over SSH.

All sources are specified as Custom Resources in a Kubernetes cluster, examples of sources are GitRepository, OCIRepository, HelmRepository and Bucket resources.
