Monitoring of long-running GCP cluster

Prerequisites​

You need to have the following tools installed on your operating system:

You need to configure the gcloud CLI, so it's able to access capact project on GCP. You can follow this guide to configure it.

Setup access to GKE cluster​

Set the following environment variables in your shell:

export REGION=europe-west1
export CLUSTER_NAME=capact-stage

Get the kubeconfig for the long-running Capact GKE cluster:

gcloud container clusters get-credentials ${CLUSTER_NAME} --region ${REGION}

This command adds a new context to your local kubeconfig file. The name of the context will be in the format gke_<project_name>_<region>_<cluster_name>. Switch to the long-running Capact cluster context:

kubectl config get-contexts
CURRENT   NAME                                         CLUSTER                                      AUTHINFO                                     NAMESPACE
*         gke_capact_europe-west1_capact-stage         gke_capact_europe-west1_capact-stage         gke_capact_europe-west1_capact-stage         capact-system
          kind-kind-dev-capact                         kind-kind-dev-capact                         kind-kind-dev-capact                         local-scenario
kubectl config use-context gke_capact_europe-west1_capact-stage

Now run the script to add your public IP address to the authorized control plane networks, so you will be able to make queries to the GKE API server:

./hack/monitoring/manage-ip.sh add

Check the cluster metrics​

Follow this guide to connect to Grafana and check the cluster metrics.

Remove your IP from the authorized list​

Once you are done, run the following script to remove your IP from the authorized GKE control plane networks:

./hack/monitoring/manage-ip.sh remove
