Now we will use Helm to install Weave Flux into our cluster and enable it to interact with our Kubernetes configuration GitHub repo.
First, install the Flux Custom Resource Definition:
kubectl apply -f https://raw.githubusercontent.com/fluxcd/flux/helm-0.10.1/deploy-helm/flux-helm-release-crd.yaml
Check that Tiller is installed.
tiller has already been installed, this command should either return a list of helm charts that have already been deployed or nothing.
If you get the message Error: could not find tiller, see installing helm for instructions.
Next, add the Flux chart repository to Helm and install Flux.
Update the Git URL below to match your user name and Kubernetes configuration manifest repository.
helm repo add fluxcd https://charts.fluxcd.io helm upgrade -i flux \ --set helmOperator.create=true \ --set helmOperator.createCRD=false \ --set firstname.lastname@example.org:YOURUSER/k8s-config \ --namespace flux \ fluxcd/flux
Watch the install and confirm everything starts. There should be 3 pods.
kubectl get pods -n flux
Install fluxctl in order to get the SSH key to allow GitHub write access. This allows Flux to keep the configuration in GitHub in sync with the configuration deployed in the cluster.
sudo wget -O /usr/local/bin/fluxctl https://github.com/fluxcd/flux/releases/download/1.14.1/fluxctl_linux_amd64 sudo chmod 755 /usr/local/bin/fluxctl fluxctl version fluxctl identity --k8s-fwd-ns flux
Copy the provided key and add that as a deploy key in the GitHub repository.
Now Flux is configured and should be ready to pull configuration.
