Levantar Prometheus y Graphana:
docker run -p 9090:9090 -v /c/Users/cha14309/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
docker run -d --name=grafana -p 3000:3000 grafana/grafana

Kubernetes Horizonthal Pod Autoescaler:
minikube start
minikube addons enable heapster
Esperar algunos minutos y:
kubectl top node
kubectl top pod --all-namespaces
Ver Grafana en un browser:
minikube service monitoring-grafana -n kube-system
& minikube docker-env | Invoke-Expression
mvn clean install
docker build -t diegochavezcarro/product-app:1.0.0 .
kubectl create -f .\product-app-k8s-template.yaml
kubectl create -f .\product-hpa.yaml
Ir viendo que pasa:
kubectl get hpa,deployment
No anduvo.
kubectl run -it --rm --restart=Never prueba --image=busybox -- sh -c "wget -O - -q http://product-service/products/:8082"
Probar metrics-server:
git clone https://github.com/kubernetes-incubator/metrics-server.git
kubectl apply -f metrics-server/deploy/1.8+/
kubernetes-sigs/metrics-server#97
Cambiar:
kubectl apply -f .\metrics-server\deploy\1.8+\metrics-server-deployment.yaml
Probar si se instalo:
kubectl top node
kubectl get hpa,deployment
kubectl describe hpa
Se vera como escala hacia abajo
Para escalar hacia arriba:
kubectl run -it --rm --restart=Never loadgenerator --image=busybox -- sh -c "while true; do wget -O - -q http://product-service:8082/products/; done"
Crear multibranc pipeline, en el codigo ingresar la credencial de github con user y pass y elegir el repo
Para los web kooks, aunque no va a andar pq el jenkins es local:
- Add a 'Secret Text' global credential. The secret should be your access token from GitHub that probably has at least write access to repos (I didn't investigate which roles are required). ID and description doesn't matter. This must be 'Secret Text' for the next pieces to work right 2.Go to Manage Jenkins -> Configure System and down to 'GitHub Servers'
- Hit 'Add GitHub Server' Name - doesn't matter API URL - since I don't have a private GitHub Enterprise install (just private repos on github.com) I used the default of https://api.github.com Credentials - the 'Secret Text' credential from earlier (this dropdown only pulls 'Secret Text' credentials) Manage Hooks - checked
- Hit 'Test Connection' to make sure everything is kosher
- Go to your organization and 'Scan Organization Now' on the left
