Flux Lab: Install Flux to a Cluster📜

Install Flux📜


(Fedora Note)

kubectl is a prereq for flux, and flux expects it in /usr/local/bin/kubectl

symlink it or copy the binary to fix errors.

Verify there’s no issue with your IronBank Image Pull Credentials📜

  • The goal here is to left shift feedback of potential problems before they occur.
# Note: In production you'd use an IronBank service account / robot credential like this: 
# export REGISTRY1_USER='robot-ironbank+bigbang-onboarding-imagepull'
# For demos you can use your personal credentials

export REGISTRY1_USER=$(sops --decrypt ~/Desktop/bootstrap/base/secrets.enc.yaml | grep username | tr -d " " | cut -d : -f 2)
export REGISTRY1_TOKEN=$(sops --decrypt ~/Desktop/bootstrap/base/secrets.enc.yaml | grep password | tr -d " " | cut -d : -f 2)

echo $REGISTRY1_TOKEN | docker login --username $REGISTRY1_USER --password-stdin

Install flux.yaml to the cluster📜

cd ~/Desktop
git clone
cd bigbang/

kubectl get pod -n=flux-system

Now new objects types are recognized inside of the cluster📜

kubectl get crds | grep flux

Thanks to flux install adding newly recognized resource types / CRDs In the next lab we’ll get feedback when we run these commands kubectl get gitrepositories --all-namespaces kubectl get kustomizations -A The expected output is: no resources found Unless you already ran kubectl apply bigbang.yaml those are fine / they get fixed in a future lab. The significance of this command is that it at least recognized kustomizations and git repositories as valid object types
