# Description
#
#   Deploy the APM Daemonset POD agent on a Kubernetes cluster
#
# Usage:
#
#     1. Customize the env variables in the container definition (container name: apm-daemonset-pod-agent)
#
#       replace {{APM Daemonset POD agent image URI}} for example: 1234-5678-90.dkr.ecr.eu-west-3.amazonaws.com/alluvio-aternity-apm-daemonset-pod-agent:23.8
#       replace {{ALLUVIO_ATERNITY_APM_CUSTOMER_ID}}, for example: 12341234-12341234-13241234
#       replace {{ALLUVIO_ATERNITY_APM_SAAS_SERVER_HOST}} for example: agents.apm.my_environment.aternity.com
#
#     2. Apply  
#
#       kubectl apply -f apm-daemonset-pod-agent.yaml
#
#     3. Check resources status
#
#       kubectl --namespace alluvio-aternity get daemonset
#
#       kubectl --namespace alluvio-aternity get pod
#
#     4. Clean up
#
#       kubectl delete -f apm-daemonset-pod-agent.yaml
