I'm setting up a kubernetes cluster on digitalocean ubuntu machines. I got the cluster up and running following this get started guide ubuntu. During the setup the ENABLE_NODE_LOGGING, ENABLE_CLUSTER_LOGGING and ENABLE_CLUSTER_DNS variables are set to true in the config-default.sh.
However there is no controller, services created for elasticsearch/kabana. I did have to run the deployAddon.sh manually for the skydns, do I need to do the same for logging and monitoring ? or am I missing something in the default configuration.
By default the logging and monitoring services are not in the default namespace.
You should be able to see if the services are running with kubectl cluster-info.
To look at the individual services/controllers, specify the kube-system namespace:
kubectl get service --namespace=kube-system
By default, logging and monitor is not enabled if you are installing kubernetes on ubuntu machines. It looks like someone has copied the config-default.sh script from some other folder, hence the variables ENABLE_NODE_LOGGING and ENABLE_CLUSTER_LOGGING are copied but are not used to bring up the relevant logging deployments and services.
As @Jon Mumm said, kubectl cluster-info gives you the info. But if you want to install the logging service, go to
kubernetes/cluster/addons/fluentd-elasticsearchand run
kubectl create -f es-controller.yaml -f es-service.yaml -f kibana-controller.yaml -f kibana-service.yamlwith right setup. Change the yaml files to suit your configuration and ensure kubectl is in your path.
Update 1: This will bring up kibana and logstash services
