coreos/prometheus-operator: Prometheus Operator creates/configures/manages Prometheus clusters atop Kubernetes
March 9, 2019 at 9:41:15 PM GMT+1 - permalink -Prometheus Operator vs. kube-prometheus
The Prometheus Operator makes the Prometheus configuration Kubernetes native and manages and operates Prometheus and Alertmanager clusters. It is a piece of the puzzle regarding full end-to-end monitoring.
kube-prometheus combines the Prometheus Operator with a collection of manifests to help getting started with monitoring Kubernetes itself and applications running on top of it.

Controlling nginx
March 8, 2019 at 12:03:45 PM GMT+1 - permalink -Pour un graceful shutdown de nginx, il faut un SIGQUIT
Kubernetes envoie du SIGTERM alors on peut utiliser un preStop script pour être + cool
https://kubernetes.io/docs/tasks/configure-pod-container/attach-handler-lifecycle-event/#define-poststart-and-prestop-handlersOn peut aussi utiliser le preStop pour s'assuret que le container nginx sidecar s'arrête bien avant l'autre container en posant un lock dans un shared volume. Le preStop de l'autre container va attendre que le lock soit supprimé pour se couper. Le preStop du nginx va supprimer le lock quand il a bien terminé.
On crée le lock dans un postStart

kubernetes-incubator/external-dns: Configure external DNS servers (AWS Route53, Google CloudDNS and others) for Kubernetes Ingresses and Services
March 6, 2019 at 6:10:04 PM GMT+1 * - permalink -marche bien, j'ai quand même créé une nouvelle zone et donné les droits dans le role IAM seulement sur celle-ci pour ne pas tout mélanger
Il faut désactiver le upsert only sinon les entrées DNS ne sont pas supprimées quand le service est supprimé et quand on le recrée, il n'arrive pas à update
