Apache Ignite su Kubernetes non si unisce al cluster

Question

Sto cercando di configurare un semplice cluster ignite a due nodi con kubernetes. La stessa configurazione funziona correttamente quando si esegue direttamente su VM.

Essenzialmente ho due pod che sono microservizi scritti in Vertx con Ignite come nodo incorporato, pod1 espone 9090 tramite service1e pod2 espone 9092 tramiteservice2

Entrambi i pod utilizzano ignite-serviceper esporre le porte di rilevamento Ignite 47100 e 47500 ed entrambi i pod implementano KubernetesIPFinder

pod1 --> service1(9090, 10900)   |
                                 | --> ignite-service (47100/TCP,47500/TCP)
pod2 --> service2(9092, 10900)   |               ^
                                                 |
    KubernetesIPFinder----------------------------
            ns = ignite-ns
            svc = ignite-service
        ServiceAccount (ignite-account)

Quando si avviano entrambi i pod, posso vedere la scoperta in corso, ma il secondo pod si blocca sempre con i registri seguenti. Non sono sicuro che ciò sia dovuto al modo in cui ho configurato gli oggetti k8s o a qualche contesa di risorse nei k8s.

Se è stata modificata la configurazione per utilizzare i thin client per i pod, tutto funziona correttamente. I pod sono in grado di avviare l'accensione ed esporre gli altri endpoint dell'applicazione vertx

Answer 1

Ho capito qual è il problema qui. Apparentemente ha a che fare con il modo in cui ho configurato l'oggetto servizio in Kubernetes. Non sono sicuro che si tratti di un bug o di una funzionalità, ma sembra che un nodo Ignite possa ridimensionarsi solo sul nodo e non tra i nodi. Ciò che intendo con questo è che l'oggetto servizio dovrebbe essere univoco per un nodo. Se condividi l'oggetto servizio tra nodi (microservizi) prevedendo che il cluster si diffonda su più nodi, si bloccherà. (Non sono sicuro che si tratti di un anti-pattern) Ciò che ha funzionato è stato mantenere l'oggetto servizio univoco per il nodo e quindi ridimensionare il nodo se necessario.

Penso che se questo è il caso, probabilmente dovremmo mantenere i nodi ignite come un cluster separato e non incorporati all'interno dei microservizi.

Answer 2

come per la tua distribuzione Kubernetes, probabilmente hai definito un file readinessProbesul tuospec.template.spec.container

Ciò impedirà la registrazione del pod come Endpointssotto Kubernetes Servicee ogni nodo incorporato di Ignite avvierà il proprio clusternodo di 1 :-/

provalo senza readinessProbee vedi se i tuoi nodi Ignite si uniscono allo stesso cluster.
