narwhal-delivery-zarf-package-eks-addons

This repository is used to create zarf packages of multiple add-ons for EKS.

The main intention is to be used with our terraform module terraform-aws-eks. These Zarf packages will consume resources staged in AWS automatically or with Zarf you can override the values using a values.yaml file, providing your own values with a VALUES_OVERRIDES Zarf variable for each package.

Utility Dependencies

Example of how to use the Zarf package with arbitrary overrides using zarf dev

The example below will template the output with arbitrary overrides akin to a helm template command.

# make junk dir
DEMO=$(mktemp -d)

# adding extra labels with helm chart values overrides
cat << EOF > $DEMO/cluster-autoscaler-values-overrides-demo.yaml
podLabels:
  extraLabel: "whatever"
awsRegion: "us-gov-west-1"
EOF

# go to cluster-autoscaler package dir
pushd packages/cluster-autoscaler

# template helm charts with zarf dev and zarf variables
# all output
zarf dev find-images --deploy-set VALUES_OVERRIDES=$DEMO/cluster-autoscaler-values-overrides-demo.yaml --why "kind"

# input var file changes
zarf dev find-images --deploy-set VALUES_OVERRIDES=$DEMO/cluster-autoscaler-values-overrides-demo.yaml --why "kind" | grep -A 10 -B 10 "us-gov-west-1\|whatever" 

# cleanup
popd
rm -rf $DEMO
unset DEMO
