This is home to example code for exposing SLIs using open source code in prometheus.
$ gcloud builds submit --project $GOOGLE_PROJECTin the root directory.- These images are currently published and publicly available from the project
cre-prometheus-slo-alerting.
- Install Terraform
- Set up terraform env (assumes you have a working gcloud install and a google project):
$ [[ $CLOUD_SHELL ]] || gcloud auth application-default login
$ export GOOGLE_PROJECT=$(gcloud config get-value project)
$ export REGION=europe-west2
$ cd terraform$ terraform init- installs terraform deps$ terraform apply -var "gcp_region=$REGION"- Will ask you before it does anything. Will take ~10m to actually run. You can also runterraform planto just get a dry run output.$ gcloud container clusters get-credentials example --region $REGION --project $GOOGLE_PROJECT- Configureskubectlto work with the cluster you just created.$ kubectl create clusterrolebinding $USER-cluster-admin-binding --clusterrole=cluster-admin --user=$(gcloud config get-value account --project $GOOGLE_PROJECT)- Gives your user permissions to create cluster role bindings that prometheus needs.$ kubectl apply -f ./k8s
$ cd terraform; terraform destroy -var "gcp_region=$REGION"
- Start kubernetes (see https://kubernetes.io/docs/setup/pick-right-solution/#local-machine-solutions ).
- Run
$ kubectl config current-contextto make sure you are in the correct context. $ cd terraform$ kubectl apply -f ./k8s$ kubectl get services --namespace=monitoringyou will see something like:
$ kubectl get services --namespace=monitoring
