node-tagger is a Kubernetes operator that applies specified tags to all aws nodes of the cluster.
The controller requires AWS credentials to be set before deploying it. This is accomplished by creating a secret with name aws-credentials in the controller namespace with the following keys:
- AWS_ACCESS_KEY_ID
- AWS_SECRET_ACCESS_KEY
For example running the following will create an appropriate secret in the node-tagger namespace:
kubectl create secret generic aws-credentials --from-literal=AWS_ACCESS_KEY_ID=access_key --from-literal=AWS_SECRET_ACCESS_KEY=secret_access_key --namespace=node-tagger
The operator requires ec2:CreateTags and ec2:DescribeInstance permissions for the nodes that we are going to tag
Deploy the operator dependencies:
kubectl apply -f deploy/service_account.yaml -n node-tagger
kubectl apply -f deploy/role.yaml -n node-tagger
kubectl apply -f deploy/role_binding.yaml -n node-tagger
Deploy the operator:
kubectl apply -f deploy/deployment.yaml -n node-tagger
