Update cdnos controller image

AWS

To update cdnos controller, update the image tag on makefile: This line:

CONTROLLER_IMG ?= public.ecr.aws/dn/cdnos-controller:<your-tag>

Rebuild the image:

make docker-build

Connect to aws ecr registry:

aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws/dn

Push image to registry:

make docker-push

We want to keep the latest tag updated so tag the image to latest:

docker tag public.ecr.aws/dn/cdnos-controller:<your-tag> public.ecr.aws/dn/cdnos-controller:latest

And push it to AWS ecr:

docker push public.ecr.aws/dn/cdnos-controller:latest

You should now be able to pull the image:

docker pull public.ecr.aws/dn/cdnos-controller:<your-tag>

Manifest

We need to update the kubernetes manifest with the new image tag. Modify this line in config/manager/kustomization.yaml:

newTag: "<your tag>"

Generate the manifest:

make generate-manifest

The new manifest is now available at this path: config/manifests/manifest.yaml.
